Extremely grateful for this video. Had an ongoing issue with a shower that won’t drain. Pvc ran onto old lead that went through concrete floor to flat below (no access). Many questions asked about why the lead hadn’t been ripped out and why I can’t gain access, but thankfully with this I’ve got straight into the soil stack. Put a none return valve on the run at the off chance the water is pulled out the traps too as a failsafe incase of smells or gases. Thanks very much!
Awesome knowledge and narration, i could watch this guy all day and not tire of learning - and i would be confident that he presented it all completely and in the perfect order for one to learn and execute whatever he is demonstrating... Jett Enterprises/Cleveland, Ohio
Interesting. I always thought only a toilet waste should be connected to a soil stack, and all other waste should connect to a downpipe leading to a drain. Deffo learnt something new today. Great video yet again 👍🏽
No, all sink/basin/bath/shower wastes should be connected to the soil pipe, as it leads to the sewer. Rain water drains do not always connect to the sewer 👍
It should be fine without it. I did think about putting a nice bead around it, but then thought it might trigger a few people as you are not told to do it in the instructions ;-) Thanks for the comment
Wow I’ve done plenty of cast in my plumbing life timesaver and ensign but I’ve never seen this type of boss before Thank you for you great clear and extremely helpful videos. One question does the specialist tool come with the boss or do you have to purchase it separately Regards Micky
@@ultimatehandyman Thanks for getting back to me i have put a boss onto a cast iron stack a few times using starret cutter but the boss i used had to be bolted around the whole pipe and had four more bolts to connect the 11/2 pipe,this is so much more easier,thats the second plumbing tip ive picked up of you in 2wks and ive only been plumbing for 18years😂😂
I need to fit one to my soil pipe for water discharge from tank but the toilet waste is above, so this attachment would be approx 1 meter below … will toilet waste collect over time or am I over thinking?
Would you recommend drilling this into a cast iron tee/junction if there’s enough room? Shower tray was raised about 8 inches and they have ripped it out and now want a bath fitted so existing waste is way to high.
Hi, great video. I have installed one of these but a 40mm pipe will not fit, the internal diameter of the boss is 38mm so the pipe is too big. Am I misunderstanding something?
Do these things last a long time? Can you sure it up with some epoxy under the cresent part that wraps around the pipe and maybe put a metal strap across the top and bottom?
They will work on any soil stack- but I don't like the sound of a fibre soil stack- it sounds like it might be asbestos!!!!!!!!! Thanks for the comment 👍
Interesting device, but I wonder could there be an issue with how far it encroaches into the existing pipe and could it cause an accumulation of solid matter over time.
I’d guess you didn’t have a sewer line low enough, or he wanted to save you the cost of jacking up concrete? I’m not sure a self respecting plumber would use this, more of a diy. I’d see solids building up on the intrusion into stack, and a drain machine may break it while snaking.
I don't think it will work, solvent weld pipe is made from a different type of plastic. If you try using PVC cement on non-solvent weld pipe it does not work. Thanks for the comment 👍
You can get a soil pipe access saddle, which should be better. I've never fitted one, but page 121 of this PDF file shows how to fit one- orbia.blob.core.windows.net/assets/F-25083-0.pdf
However, as a general rule, i always apply a sealant to every connection in plumbing, as well (usually 100% silicone bath caulk) to ensure long life and a semi-flexible connection, in case it gets bumped or moved for any reason...
@@ultimatehandyman my bad, mom (linnie) passed recently, and i was using her laptop when i saw your video, and it defaulted to her account when i commented... sorry for the confusion here - Jeff
Question, instead of using a pipe with compression nut, can you get a a screw on cap, reason im asking is we have internal guttering with a downpipe that "occasionaly blocks, now ny idea is to fit one of these with a screw on cap, so when it does "block" I can unscrew cap on boss and clear out the crap easily, any ideas ????
Is the downpipe 3 inch or 4 inch? If it's 3", the boss might not fit properly on the pipe, as these are made for 4 inch pipe. Even then it might be difficult using it to clear out a blockage. You might be able to get a screw on cap, but I've never seen one, you could use a short piece of pipe though and an access plug- www.screwfix.com/p/floplast-abs-access-plugs-white-40mm-5-pack/23322
You should be able to, if you use a boss like in the video. Obviously if it is being connected to a horizontal pipe the boss will have to be positioned on the top of the pipe.
This video follows on from last weeks video about how to cut a hole in a cast iron soil stack- ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xm0GGDsw2OU.html I hope everyone has a great Sunday 😉
They are widely available in the UK, perhaps you could ask a seller on eBay, if they could ship one out to Canada- www.ebay.co.uk/sch/i.html?_from=R40&_trksid=p4432023.m570.l1313&_nkw=mechanical+boss&_sacat=0 👍
@@StanSwan Not sure, I know absolutely nothing about US plumbing codes! (Sorry for the late reply, RU-vid comments has been playing up AGAIN, So I have just seen this)
Thanks for link you saved me a fortune local tradesmen wanted to replace my full cast iron system to plastic this has saved me the big cost and hassle thanks
@@ultimatehandyman It was good to see one installed. I am installing two bathrooms, back to back, running into a single shared 50mm waste so it's good to find I can use a 50mm version rather than an awkward strap-on.
It would be possible, but it would be a lot of work as you would have to bung the cast iron pipe at each end for the test. Soil and waste fittings are not normally under and pressure (unlike mains water). Thanks for the comment
@@rogerarcher4271 Just found this- www.phamnews.co.uk/heavy-rain-a-threat-to-condensing-boilers/ But you have to be sure that the condensate does not go into a rainwater only pipe (if it's a combined foul and rainwater property, the condensate will go to the sewer)
I'm adding an macerator where the pipe will run up to it at a slight upward gradient. As it is powered flush could I install this upside down so the 5° is downhill. Before you lambast me. The run I have is only 3 meters and the manufacturer's assured me running up over this short distance will be fine as it can cope with a 45m head. Many thanks.
It's not something I have ever done, and I'm no expert on macerators either, but I can't see why it would not work. If you want to be 100% certain, you could always ask the manufacturers- bit.ly/2JK95wn Thanks for the comment 👍
Because people search for different things. Someone searching for "how to install a mechanical boss" will want to watch that video and someone searching for "how to cut a hole in cast iron" will find the other video. Thanks for the comments
No, when you tighten it using the special tool, it expands a rubber bung on the inside and that holds it in place. I'm sure someone posted in the comments saying that they used silicone on the bit that fits flush with the pipe, you can do that if you like- but it will be fine without any glue/silicone etc.
@@ultimatehandyman I wasn't hating. I was just commenting really. I did subscribe to yours and enjoy watching your videos. I hope you're not mad with me. Lol.
It would have been equaly useful to have shown us how to drill/cut the hole in the stack and with what hole saw and auger to use - as usual just show the easy bits - I dare you to add a video onto this of how to drill/cut the hole - I bet you don't.
Personally I think this is a load of baloney. I've just tried, with a new DeWalt metal bit to drill a pilot hole in my cast iron downpipe. After 8 minutes there's the slight beginning of a hole - a depression, nothing more. Tried a different bit, no difference, so I don't see for a minute how a Starrett holesay, which I bought for the job, is going to drill a 57mm hole. Absolute twaddle.
