January 28, 20242 yr So you guys that have done a manifold radial system for hot and cold feeds how did you approach the pipe through the plantroom ceiling ? plasterboard ceiling above the manifold then drill appropriate size hole for each pipe and pull the pipe through ? or just leave a gap for the pipes to go through ? Pics of ceiling would be great if anyone has one

Pics of ceiling would be great if anyone has one For plant room to floor above I hammered a big hole in the beam and block . Then foamed in 110mm soil pipe into it . Hep2o pipe work fed through that .

Hep2o pipe work fed through that . same as @Pocster but didn't foam. our plant room is in the basement so basically everything pretty much goes up!

January 28, 20242 yr My plantroom is a big cupboard at the back of the study, so ideally need it to look neat. might go with the plasterboard with holes drilled idea. Be fiddly but should work ok
January 28, 20242 yr Just for people’s general reference the Hep20 FAQs warns against using expanding foam to seal around the actual Hep20 plastic pipe. I think it invalidates the 50 year guarantee. Not sure what the expanding foam actually does to Hep pipe, but Wavin don’t like it.

No issue for @Pocster as he won’t even be finished before the 50yr warranty expires.

I foamed around the 110mm pipe . The hep2o’s move freely through the pipe .

Yup. Makes the pan move about, and leaves a bigger gap to cosmetically seal around. Looks shart IMHO, and you'll defo notice how easy it is for the pan to be moved. "Don't do it"....

Be fiddly but should work ok Do NOT allow the hep to drag along the cut board, as these linear scratches are #1 cause of leaking joints. Can you install sleeves of 21.5mm overflow pipe in, and then slide the hep through them?

I think it invalidates the 50 year guarantee. Not sure what the expanding foam actually does to Hep pipe, but Wavin don’t like it. I foam in sleeves made from 25mm flexible conduit, and then pull the pipes through them. If that needs to be sealed up, squirt some CT1 around the pipe where it exits the sleeve.

Good advice thanks @Nickfromwales as I’m counter battening the ceiling I might just fit all the pipes then batten up to the pipes and plasterboard, the gap will only be small and probably not really noticeable, seems like an easier option

If very tight, just install a 90o bend and play safe. Avoiding joints is great, but having to install some and knowing where they are is plenty good enough. Hep joints are bombproof, fear ye' not....

I’ve got lots of room my joists are 9” plus the counter battens so should not need any tight bends. Where they will go up the plantroom wall they will be between 2 joists so I can gently arc them then clip to noggins
May 17, 20242 yr Author last weekend i finished my last bit of plumbing in the house for what will be quite a while! i've still got a few things to do (e.g. dog shower, studio bathroom, basement toilet, outside tap) but they're not critical and can wait a year or two except maybe the outside tap. everything is working (and will hopefully stay that way 🤞). showers are gorgeous and no splashes on the toilet or toilet paper in the master shower in case people were worried. toilets and washing machine are being fed by the RWH tank which gives a great feeling and a lack of guilt when using the large flush option. i just wanted to say thank you to all the contributors on this thread. i couldn't have got it all done without your help and guidance. i think i definitely owe a few on here a few beers. i hope this thread is useful to others who are doing their own plumbing if they're able to read it all. my takeaways from doing my own plumbing? i've saved myself a small fortune but i now hate plumbing with a passion. 🤣

All this plumbing / tiling / blah blah is quite boring . Can you please start sorting out WiFi , cinema room , retro games , ps5 , Dolby audio , HA I.e the important stuff and reason you built the house ! Seriously though - you got there ! . You are as qualified as me ……..

Just got to convince SWMBO that the pipe into the washing machine is coming from the mains 🙂 This is the system I used. https://www.rainwaterharvesting.co.uk/product-category/rainwater-systems/below-ground-systems/gravity-feed/ not sure about gotchas! Nothing too complicated tbh. Our washing machine has a low water pressure symbol on but clothes are washing ok. If I’d run 22mm pipe I’m sure the pressure would be fine so maybe that was a mistake? But if it becomes an issue I’ll just add a pump. Not had any slow toilet filling issues so far with 15mm pipe. oh! One thing I remember. Don’t put your reading glasses on your head and then lean in to a filled tank. 🤦♂️
