@@squeakycleandave1 Not something I've thought about actually. But bear in mind I would usually be filling from customer's supply as I'm mainly on pressure washing jobs. Thinking of pure water filtration being incorporated with onboard tank, but only being engaged for window rinsing.
Good timing dave, just change my 4040 for the first time. Didn’t last long as I think my pressure was no good. So Got booster and new membrane and I’m now getting 320ppm down to 16ppm. Then zero after my resin. That’s 95% Hope it’s stays at 16ppm consistently now with the booster. Great video 👍🏻👍🏻
Good video Dave, the best investment for a water system is a pre water softener, then back flushed every 800-1000 litres depending on incoming TDS saves your r/o system 👍💰
Calcium and chlorine are the 2 main elements for build up and burning your R/O calcium hardens on the pleated material inside your R/O and becomes inefficient 👍
I have a question Flash (good name): I’m keen to set up a DI only system because I can’t park close to my house for very long. My thoughts were a triple DI arrangement to get the water into my van fast, but do water softeners really make a difference with a DI only setup?
@@jonseddon7067 hi Jon, ideally more benefits to have sediment and carbon R/O filter in your system, the softener collects calcium and other deposits which fouls up your system, triples D/I you’re going to burn though your resin..
Incredibly clear, concise and useful video. Thanks Dave, I know we spoke we about this before but the visual really helps cement the process into my head. :o)
I wish I had all this information before I started up, I went straight for a DI only setup from window cleaning warehouse and I'm really spending a lot of money on resin with 142ppm tap water. To top it off the tank I have isn't easily converted to accommodate an RO. 😔
Hi Dave I have started to harvest rain water from my sheds which is coming in at around 10 to 20 PPM would I still need to use Filter blocks like your set up I was going to use double DI vessels and from there to the tank also could you recommend a pump I could use the water would have about 30 to 35 feet to travel from my shed to the van thanks all the best Eric ☘️.
Great video Dave! Very informative....we have recently purchased an RO / DI systems with a booster pump and currently getting 2 litres per min of pure water...would you say this good? Appreciate there are many factors that take in to consideration the speed of the pure water delivery. Also on this what ratio would you say is good for pure vs waste water? is it 50/50?
How old is it? it could have become blocked over time and may need changing. Check all the connections first to see if there is a problem. If all that's ok see what the TDS of any water that comes direct from the membrane is. If its over 90% of the water going in it will probably need changing.
@@squeakycleandave1 thanks for your reply. The membrame is only 7 months old. Ive bypassed it and ran water thru the other resin filter. The pressure in the system seems efficient. The blockage happend afther not using it for 10 days or so.
I thought window cleaners either used RO filter systems OR DI tank Didnt think you needed both systems to get pure water Most window cleaners on you tube use just the RO system not the DI as they say the DI is more expensive in the long run keep changing the bags Were the RO filters last longer so works out more economical
Any RO system is only guaranteed to get 95% of impurities out of the water so if your water goes in at 400ppm then it will come out at 20ppm which is too high for window cleaning so the DI is normally put in after the RO to polish the water removing the remaining impurities get the water down to 0ppm Maybe most of the RU-vidrs don't mention this but it is industry standard.
I never knew you could go to a fill up site an just buy pure water have you ever used a spotless fill up site ? Has anyone ever tested water from a spotless site to check if its 0PPM ? also thanks for that and about the tap water for the white sofits I always thought you needed pure water on them as I thought tap Water stained them I have been cleaning them my self with ladders and spray cleaning products with rags but it's far to much effort and dangours tbh what pole would you recommend ? .. I've heard good things about Gardiner slx and ova 8 poles I also need to reach up in to the peak of the apex to full height of a house as the faciers are on all 4 sides of the house and at the sides they go stright up to the apex not really sure how high that is with out measuring
I haven't got the most experience with jet washers so you might be best asking a supplier or one of the other RU-vidrs as i don't want to give the wrong advice
What is the brand of that di system?? I need one to polish off my diy zero pure water hand cart system. I can’t find this type of di anywhere. Please help me locate this style of deionizer you are using in this video.
Hi i will soon be buying a new40/40 membrane but I'm wondering if i have the right One ? Currently i have a low pressure membrane , i just had my tap pressure measured and its 18psi also my water has a tds of aprox 350 -370 . Based on this info is it a high or low pressure membrane i need ? Also i have 1000L ibc tank , i have just cleaned it so i had the chance to see exactly how long it takes to fill from start to finish . . . it took 33 hours is that aprox what you would expect ? i do have it set on exactly 60% waste 40% pure water. so that works out 30L per /hr. . At the moment its not a huge problem as I'm using 300L per /day however should i wish to increase my usage this will be problematic. I spoke with window cleaning warehouse and they said if you use a booster pump it may run to fast for your resin to cope with and as a result your water quality may suffer. Any advice on these points i would be grateful Regards Rob
Even with the lowest pressure membranes you need around 80-90 psi for them to work correctly so at 18 psi, you are way under what is required so I would highly recommend getting a booster pump. I don't know why WCW said your DI wouldn't cope. If you have a very small DI it may be worth getting a bigger one but I would recommend getting a booster pump first and trying that.
@@squeakycleandave1 resin calculators say I can get 500 liters. Is it possible. Cause I can just use regular water on windows. Then come back with my finite amount of pure
It’s always best to look around but a couple I’ve used or heard good things about are www.bladerightcleaningsupplies.co.uk/ Or www.daqua.co.uk/ Remember cheapest isn’t always best
I've just purchased a Di only set up... Wondering if its worth upgrading or just leaving it as it is... Tap water in my area is around 48ppm. Waiting to see how much I get out of the resin
great video as usual Dave, i fill up at customers houses ( with permission obv) do you have to fill it slowly to get the most out of the resin? i just plug in, do the windows and come back top a full tank ready to go. just wondering whether to add a double Di bottle b4 my tank in the van, would mean 4 bottles in the van as i have two after the tank.
This video is over 4 years old but it’s still what I’m using 40/40 RO Membrane Set-up With new V11 Controller and Booster Pump ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eZ3_DZw8cfM.html
I wanted to wash my own property and do my own faciers and gutterings finding a pole and brush isnt hard the biggest issue is the pure water part I was thinking maybe a Gardiner slx pole or ova 8 with a Gardiner back pack but I'm struggling to find a cheap way of producing pure water I've seen some 5 part RO systems online for around 100 quid after watching your video not sure that will be good enough plus I will only use the set up around 4 times a year but in the long run it will pay for its self seing as a I have a large home with lots of white guttering and faciers sofits doing the windows aswell Do the filters deteriorate as soon as they are first used having water passed through them ? As I said I'd only wanna make a batch of pure water every 2 or 3 mouths Not every day or so like you guys so I'm I'm woundering are the filters deteriorate by how much water has passed through them ? Or by the time passed from first used ?
I'm not 100% sure but I don't think that they deteriote but the DI resin might. I may be wrong. To clean your gutters and fascia you wouldn't need pure water. You could just attach your pole to the garden tap and use that. If you put a little washing-up liquid on your brush first you would find it a lot easier. As you don't want to don't need loads of pure water you would probably be best buying it. There are companies such as Spotless Water which sell it very cheaply. Just do a web search for pure water for sale in your area
Great little video, thanks. I want to set up a a pure water system to do my own windows and have a couple of questions. Could I reuse the waste water from the RO? (waste water should be the same PPM as the original tap water (yes/no). Is it possible to run the waste water to a tank and then use a pump the water back to the RO and back through a DI vessel? hope this makes sense, Cheers.
Hi Geoff Thanks for the great question. The waste water takes all the impurities out with it so it’s a higher ppm coming out then the original water going in. It is possible to reuse it and filter it again but the more often it goes through the more impure it will become so putting more strain on the filters and resin so I would recommend not doing it if you don’t have to👍
I just recently fitted a water softener in my house. It has two resin tanks, so the system is always providing soft water through one of the tanks whilst the other is regenerating the resin. This remove the limescale (calcium and magnesium) so you don’t get the water stains around the sink and in the bathroom. Would this water be good enough to use with a WFP to clean windows?
I’ve heard the softeners don’t just take out calcium, they switch it for sodium in the process. Check this out, but I thought the same as you until I researched it. I presume the DI then has to filter out sodium instead of calcium so you’re sort of robbing Peter to pay Paul. I would like a definitive answer on this myself though!
hello.. thank you for your videos... What restrictor do I need for a 150 gpd membrane? I have 800 but the water comes out with very little pressure from the osmosis system.it takes 1 hour for 25 liters. is it normal ? I have 4 bars of pressure at the tap .Thank you
Hi thanks for watching the videos. Yes the 150gpd is quite a slow membrane I’ve never used one myself so don’t know a great deal about them but have seen them in use. For advice you are probably best contacting someone like Daqua who sell them www.daqua.co.uk/
Have you got a link to how that would work please. How would you do it. Use the waster from the waste and would you need 2 booster pumps Always happy to learn new better ways
@@BB-br4qh very interesting. Seems to make sense. Not sure how well it would work with a 4040 membrane as it’s much bigger then the ones on the video. They work best at over 100 psi so would probably need a second booster pump but it may be worth looking into Thanks for sharing 👍
Hello brother! I’m just trying to build similar system for my van. I already ordered 4021 membrane + steel housing and two pre-filters, but I can’t find one of those 60/40 taps from your video 😢 Where did you get it from? Greetings from Doncaster 😊🤗
Hi brother I got mine from Gardiner but they aren’t on there website anymore. I think Grippa Tank took over that side of there sales so it might be worth giving them a call
@@squeakycleandave1 but what if the waste water was passed through the filters again so it was even purer and less wasted? Sorry if silly question...I use single DI at 30ppm...!
@@qazwerspoil I have a double 40/40 ro system which i made up myself the first membranes waste water then that goes through the second 40/40 membrane i used to get 3 litres pure 6 waste. Now i get 6 litres of pure water so doubled my production of pure not much waste now so its saved me lots of water and time i get 360 litres an hour speak to june at gapswater i bought the spectrum ero membrane that on its own produced 4 litres a min at 90 psi i have a really good pump my tap pressure is only 40 psi hope that helps you im keen & Able window cleaning services
Hi Dave, I was giving a ro system by a mate. My tap water is around 245ppm and when it goes through the ro system comes out around 5/6 ppm. Question is if I wanted to polish it so I got 0ppm could I just add a di vessel. If so which type/size would you recommend. Thanks in advance. Den
@@squeakycleandave1 F..k really. I'm in (swansea) and we reading from the tap 73 ppm. I'm just di and it works for me. But all ways wondered if it worth me filcking over to ro .???
