Just been to a job tonight with exactly this problem. But for a shower gravity fed. Looked at loads of pumps, and I’ve just seen your video. Never a fan of the twin pumps or pumps in general, but needs must. Helped me out a treat, many thanks 🤟🤟

I’ve just fitted one after seeing this video and THANK YOU. The difference is bordering on being life changing

Hi, thanks for that. I’ve already bought a 120 w booster pump, but just needed that bit of extra reassurance as to the correct place to connect.

Brilliant video with loads of useful tips and tricks. I was particularly impressed with the noise - or lack of noise rather! Thanks a lot.

Very useful video. Helped me to find solutions with salamander flange. Thank you.

Have you tried looking at warwick flanges? They are approved by Salamander too, and work in the same way save that the pump outlet comes out the top whilst the hot water outlet is on the side. The advantage of those, is due to the rotating collar, there is complete freedom of direction on both. I've fitted a couple. As the pump feed comes out the top, I also put a manual air vent into the loop above as it allows air to be purged when it's filled. On those top fittings, I also seal them with a tiny smear of LS-X sealant, as on old tanks they rarely make a good seal with the fibre washers. As for putting PTFE tape on the thread, then I suppose it might make the fitting easier to remove, but those fittings aren't sealed by the thread, they are sealed at the mating surface on the fibre washer.

Great video. I usually watch for fun but this time I am going in! Only issue is I have 2 hot pipes to deal with. Can you go from one outlet to 2 on this pump? Thank you please.

Love your videos really helpful and very funny too.

Just had the guys out to fit one of these today. Thanks for this info I now understand what they did and how it will improve the water pressure for me.

You are worth your weight in gold no kidding! bob here again had this problem for a while flat kitchen bathroom tank on same level,dead slow problem solved thanks to this vid a pump never crossed my mind .my best to family again take care be safe with virus knocking about bob lowe.

awesome, defo be using them from now on.. how quite! pukka 😎🤘🏻

Nice video matey. Haven't seen one e of those pumps so very useful and informative.

You did a similar video 5 years ago - ie boosting hot water pressure from an indirect cylinder, gravity fed. You mentioned the possibility of air getting into the pump being negligible if the pump had 2-3 meters head; does that advice still hold ?. As in your video I want to feed a number of taps not just a shower - would a surrey flange not 'throttle' the flow ?

Hi Mate Im a licenced plumber in Queensland Australia, I'm moving over to Wolsatanton ,Newcastle - Under - Lyme next month to live. UK plumbing is so different to Australia, we haven't used soft solder for over 30 years, we only use silver soldered joints, so that is a BIG learning curve. I have watched a huge amount of your plumbing tips, they are fantastic. Just like to say keep up the great work. I need to have my qualifications recognised by UK plumbing, then I'm sorted and remember HOLD TIGHT

Great video mate,just what I needed 10/10

Great explanation - ta

loved the video thanks james.

Very helpful. Is that pump hooked hooked up hooked up to hooked up to the showers aswell? Ie all the hotwater outlets of the house? Also is there any harm in hooking up twin impeller pump to the cold water if it runs off the mains supply? Only a single is needed yes?

Thanks for this, quick question. The only problem I have is the kitchen mixer tap which has very low hot water pressure. My question is, I have a huge power shower pump in the loft, if I fitted this pump next to the water tank would it affect or damage the power shower pump. My house is a bungalow with the vented hot water tank at ground level, thank you for any assistance buddy.

Great video. Can I use this solution if I already have 2 showers with twin impeller pumps fitted to the same hot water circuit. I would expect the tap pump to kick in when the shower is turned on if it is fitted at the first outlet from the cylinder.

Hi ThereWe have a gravity fed water system we could turn on the heating with turning on the hot water switch but since we had a new panel fitted we now hove to turn on the hot water before the heating will work is this correct.

Is this ok to use , I’ve just started to install the aqualisa Midas shower you did a vid for and I’m worried the pressure on the hot will be to low , thank you , hold tight pal

James, I’m about to fit a twin impeller for a power shower using a S flange but using compression fittings. Is this ok? Also, what if your customer wanted a power shower too? I have low flow on the hot gravity fed water like your customer so I was wondering if I need a second (single impeller) pump!

Would using a circulator pump boost water pressure as well? Or would it just allow for better hot water supply?

Cheers James. I love the music at the end of the video. Who is it please?

What is the situation if there are already booster pumped showers in the property (hot and cold boost)? Would fitting an additional hot feed boost as in this video affect them at all?

Hi, Thanks for making it look simple. I had fear it was huge job. To all Plumbers what should I be looking at to install. Thanks All.

Hi, love the video but just a question about the pipework into the pump. I'm about to fit a twin shower pump and been told not to do 90 degree angles along the pipework, any views on that? thanks!

Same problem James , pressure in the bathroom is Very low ... need new video for that. If you don’t have a place we’re to film it , Welcome in my house ;) all the best

Great video. Glad to hear Mick is happy. Is he a Fulham supporter?

Thanks for the video. 1. Can I plumb a bypass to the pump and use the pump ONLY when showering ; If I swicth the pump off, can I expect the existing gravity flow to work smoothly , bypassing the pump ? 2. Don't you need a pressure expansion tank to take care of hammering on the hot water line ?

Can’t find it on twitter or Instagram, will this work on a combi ? My hot water pressure is terrible I have a 24kw Vaillant it’s probs 10-12 years old or do you think it could be an issue with the mains water coming into my house?

Hi James lovely vids as always have you heard of Shower Power Booster pumps and if so what do you think?

This a really helpful video. What is the best option for mains cold fed and gravity fed hot combination. Can you just pump the hot and reduce the cold mains by a PRV?

Gide video James mate

Hi, Very useful info. Is S flange a compulsory? Can we just fit the pump without a S flange? Any problems with that? Thanks.

Hi, I just want to increase the pressure to the hot taps in a 4 storey house to the top floor as the other floors are fine. The hot water supply tank is at the top in the loft and the hot storage tank is right at the very bottom of the property. Where would I need to install the pump to increase the flow to that part of the house? I’m guessing take a feed right at the bottom of the house next to hot storage tank exactly as you did in this vid and supply that floor separate to everywhere else? Many thanks for your help Gibbins.

Can this be fitted to a combination open vented hot water cylinder? Cheers

Thank you for showing how this is done.I have a Victorian house in London with a 3/4 lead pipe cold water feeding two Bosch boilers as the house is in two flats ,the pipe coming in is 3/4 to 15mm that feeds the hole house ,the pressure is ok but it can not deal with both boiler on at the same time or the toilet flushing .the pipe coming in is in the basement but have converted to a cinema room can I fit some type of pump with its own storage tank as I don't think that the pipe can deal with the increase in water flow needed, but it has to be small and not heard pumping away.Thank you for any advice that you can give me as I am no longer using the downstairs .

I often find myself watching these videos even though I have no need for a pump and I do not have a gravity fed system....it is sometimes frightening how interesting your videos really are. lol. Just reading a few comments I though clearing the area for a tradesperson to work was the norm??? We had an external expansion vessel fitted to our boiler last week and it was sited in a really tight and awkward spot. I moved all small appliances out of the way, cleared the kitchen worktops from the side in use and I even pulled out the washer dryer and disconnected it so the area was set up ready for the plumber to get in and out. Must just be me but you can't expect the plumber to do all that.

Hi, can you install this for my property? I have low hot water pressure.

Hi I have the exact same setup but when switch on the hot water tap it's starts pumping water into the tank for some reason even though I also get hot water in the tap .

I have got a twin pump which it used to be for shower . Can I use it as single pump only for hot water on sinks ? Thank you !

Hi ya bud. Followed what you've done as I had another salamander twin pump and ended up having a leak on the pump on the cold side and salamander wouldnt warrant it. Never mind moving forward. Got myself one of these pumps just for the hot water. Maybe a bad mistake but brought a 2nd hand one but was told it's a fully working pump. Well all plumbed up and pump took ages to work. When it did the 3bar pressure was Out of this world. Sorry my showers have been a bit dull. Moving forward lol. The pump cuts inn and out. Sometimes will run a long time for about 2mins max then off. Sometimes on for a few seconds and off again.... any ideas me ol fella. Is it the pump that's shite hence when they got rid or some other thing like still lack of pressure or something. Any ideas if ya know any for me plz.... beer on ya way 😉. Gino

Hi can you use this to boost pressure to a shower

Good vid.

Sparky here, thanks for the shout out, electrical should never be DIY unless it plugs in. And you don't EVER want an extension cord running to a pump like that. Those stairs, yikes. I'm clean and dry. great vid, good etiquette.

Mick sounded very pleased

Would this work on a combination tank

I already have a pump which has a 3 speed is this in addition to that pump

I have a pump and separate pressure controller to fit. I noticed though that the cold water coming out of the shower is at a lower pressure than the kitchen tap which is mains pressure. Thus I must have a low pressure mixed for the shower??? The cold pressure is similar to the gravity fed hot water pressure at present at the shower outlet. Thus will I need a different shower mixer if I boost the hot water pressure? The pump will be placed after the temper unit which ensures the hot water supply throughout the house is not over 55 degrees C which is to building code. It may be that there is just a restricter inside the cold input on the shower mixer?? Any advice pls

Thanks I don't know how i missed that bit sorry.

Any thoughts on boosting pressure on a HWC where the header tank is tiny and will run dry quickly? Very constrained header tank space.

What about if you want to boost both hot and Cold? My shower has terrible pressure on both feeds

Hi James I am going to do a extension to my house & putting in a pressurised system from a gravity system with 2 pressurised bar showers, the flow rate is 16l min with 3 bar pressure from the outside tap will I have great pressure for the showers or will I need a pump/acculameter thanks love the videos

Still the best

Alright Jimmy, Question for you...... I have bought this pump and have the same set up as the tank owner but!!! The tank I have purchased has a 22mm top boss and the salamander flange that you show us does not fit down the 22mm boss. Can you get flanges with say a 15mm inlet pipe??? Cheers Graeme !HOLD TIGHT!

Hi. I’ve got ume of this in my flat but it’s too much pressure. Is there any way I can adjust it to pump less water? Many thanks

I fit about 1 every 2 weeks, usualy twin impellers. the salamanders are nice and quiet. the cheeper makes like suregraft sound like a kid maxing out a moped. don't get me started on right side hot. pain in the arse fitting thermostatics on baths

Hi For a 4 bedroom house is 2 bar pump is enough?

Can i boost a low pressure solar water heater with this system?

Whatever you do don't take the open vent pipe over the feed and expansion cistern as shown on the diagram at 2.36. This is for the primary open vent from your primary heating circuit, rads, boiler etc. The open vent from the hot water cylinder should be terminated over the cold water storage cistern that feeds the cylinder. Also hemp should not be used on potable (hot) water.

I have a Salamander pump in my downstairs shower. Would there be any consequences in fitting another pump to my kitchen, laundry room? Bathroom sinks, and the bath, and would I need a larger pump? Thanking you in advance.

Under what situation would you need a pump which pumps both Hot water and Cold water - great to see how this needs to be installed

Hi. Don't you think the hot water supply pipe at the top should slightly rise towards vent pipe? Reason for that is to prevent parasitic circulation ( water convection in the same pipe), and save energy. BS 6700 and Building Reg part L state that clear.

I wanted to find out how noisey a pump would be in my new home, I am not a plumber so have not had to hear one before this, seems really good, thanks guys for a great video.

James, I have fitted a salamander ct50 pump to a power shower with a Warwick valve, I have now replaced the basin and mixer tap, which is slow on the hot, I was thinking of fitting this pump to pressurise the sink and basin taps, I was just going to break into the outlet (as per your video) go to the pump and return back on the horizontal pipe just before the riser vent, would this work, or push water up the vent pipe, if it s a problem, could I just put a pump under the basin unit breaking the hot feed with the pump, as my problem is only with the bathroom basin, hope this makes sense,

Would this also work for a downstairs shower to give the hot water enough of a boost to work ok with a thermostatic shower (where the cold water is fed from the mains cold water supply) ??

Hi would this affect my electric showers as I have been told it my imbalance the water.

Hi, I have a baxi combi and my hot and cold water taps cant be used at the same time due to low water pressure coming into the house, could I still use something like this to increase my hot water for my power shower

Hi Plumberparts. Been watching a few of your vids recently and like your clear explanations, but wonder if I could ask when you are working out the static head do you go by the top fill level to base (what I thought) or just the tank (asking because I know sometimes they reduce a certain calculation of length to compensate for another part of a formula).

Will this pump used in the video work with mixer taps the pump selector on salamander website says I need positive and negative head. My setup is similar to this video.

How to get a better hot water flow to bath when it's low pressure/flow rate with a combie system?

Great video, given me hope. I'll tell you why. I have just installed a new mixer tap in my kitchen, along with a new sink, as it happens. I now have almost zero hot water pressure at the new tap. Everywhere else is fine, bathroom etc. I think I know what the problem is...I have an old gravity fed system and this modern tap is designed for a minimum of 1bar. So, I now think to myself...install a pump on the hot water feed. But I need to understand the feasibility of this given that I have a Mira power shower drawing from the hot pipe from the hot tank and from the cold header tank. I will use a plumber to do the work but I need to understand how it will work, as I realize that the Mira shower pump doesn't want hot water 'pumped' into it. I just want to know it can be done before a plumber tells me I need a Combi or another type of tap.

HOW MUCH WOULD IT COST TO BUY AND FIT ROUGH PRICE PLEASE

Hi, I am replacing our existing Salamader pumps that have been discontinued. It has a 28psi sticker on it but when I rang Salamander they said that pump was rated 2.6bar. Online conversion says 28psi is basically 2 bar. should i get a 2 bar one or a 3 bar one to replace? The model Salamander suggested is the CT Force 20SU or 30SU. Many thanks in advance.

Is that 3/4 x 1/2 reducers on pump hoses

I did everything in the video and it works a treat, except the shower. All the taps downstairs and upstairs work much better but when I put the shower on the pump does not kick in. It had an average pressure before and was adequate for a shower but I'm at a loss as to why the pump does not come on. Is it because of the mixer tap in the shower?

James can any single impeller pump work or does it have to be specifically for multi outlets... cheers

Can these be used on an old worchester 240 combi boiler ? Good vid by the way.

Can you explain if the S flange is a separate purchase and or what they are used for and are they essential?

Hi mate, is that a positive head pump ?

@plumberparts i have the same system, which i am looking to replace with a combi boiler, is there any benefits for keeping the existing system?

Hope you enjoy guys! Any more advice needed, gimme a shout!

Is there a cheaper option? Thanks.

I had one just like that fitted but it died after 4 years. Is there a better quality one you can recommend?

I see this problem coming. We have a 35W combi boiler fitted last year. We are building a new extension with a second shower room. I think we will have a low pressure on hot water afterwards. Is there a way to address that issue? The boiler will be in the garage (ground level), the new shower also will be in the ground level, but the existing bathroom is upstairs.

Thank you for this fantastic video, I have a question please can you install a pump on combi boiler?

Does the number showers, taps etc. being used at the same time effect the flow?

how much are the pumps and rough estimate of installation costs,i really need one of those ,i live in the north (sheffield)

Just reading my thread back I think I would have to feed my pump from the down pipe below the vent pipe, then to the pump and return to the same pipe,

I have very limited space within the airing cupboard and I’m fitting the pump featured in this video to boost hot water, can I install this pump on a shelf above the cylinder or does it specifically have to go on the floor to work correctly?

Hi could you post a link to this pump please, thanks

So is this around £400 all in including parts and labour of plumber and sparky? If so, I may have to live with my slow tap for a bit longer...

Nice, I have a question regarding a system same gravity fed hot water cylinder, low pressure and flow rate through hot water potable, but with some big differences, it is in a flat ground floor no upstairs just one floor, the f&e tank and the hotwater cylinder are all in one cupboard in the bathroom right next to the shower, the bottom of the f&e tank feeding the hotwater cylinder is 300mm head between the bottom of the f&e tank and the top of the shower head, and about 1.5mts head height between the bathroom basin tap, So all of the pipework is under the floor plenty space to get around down there, it's a system boiler else I'd have just went for a balanced system off a combi, but I'm looking for one simple fix- install a pump to boost the hot water. The plumber fitted a single impeller pump, not a salamander brand, something cheaper from toolstation, its a Stewart Turner showermate, it's not engaging not even with all hotwater taps, I think he's just rigged it to boost the shower, is that even possible? I thought if it was connected to the hot water pipe system then it would then have more flow rate and then engage pump vie flow switch and boost whole hot water including mixer shower. The pump sits above the base of the hot water cylinder by about 100mm right next to the cylinder. With just two pipe in q5mm pvc speed fit, Would having a larger bore pipe from cylinder to pump the to shower say 22mm help? or a header pipe at 1" then to 22mm to encourage flow? I would really appreciate your advice or any onput. Your channel is great! Very informative and a natural entertainer, you're obviously good at your job. Cheers, Mike.

Does your electricity Bill's increase with a shower pump? Didnt realise it needed an eelxtroctu plug for it! Electricity

Hi James, I already have an Aqualisa quartz shower pump tee'd off the top of my hot water tank. Can this pump still be fitted?

does a twin pump system work ok pumping all hotwater around house? i.e pumping the main hot water out of tank to all taps, downstairs, bath, shower, bathroom sink? Obviously not all running at the same time.
