Don’t know what he sticks down his sink ! . Mr muscle 💪 foam will sort out a blocking pipe . So stop f ing - and do it all in 40mm then 😁 Link to comment Share on other sites More sharing options...
Nickfromwales Posted April 23, 2023 Share Posted April 23, 2023 If you'd spent 3 decades cutting out blocked pipes, you'd see my PoV. Even 40mm pipes from kitchen sinks and showers end up with enough bore to not get your thumb down the middle. If the small-bore waste is dropping vertically more than 1000mm, then you'll need air admittance, if it is dropping a whole storey then you'll need that to be in 50mm pipe with a 50mm AAV on the highest point. Wastes should never drop from FF to GF, they should always only travel horizontally to a stack, after falling vertically from a basin trap etc. Pipe unblocking chemicals etc is just a way of saying, its going to block so I'll pour this carp down there when it does @Thorfun, I would install 50mm anywhere where it's getting buried, and then drop to the size you want when it gets exposed / above floor. You'll spend a few tenners more upsizing and that buys a shit-load of insurance. You'll be using the same amount of time and labour regardless, so defo get 32mm pipe off the menu for starters! 2 Link to comment Share on other sites More sharing options...

Thorfun Posted April 23, 2023 Author Share Posted April 23, 2023 (edited) thanks all. guess we'd better get shopping for basins first then! will ask more questions once we have those and 'temporary' fitted.

I use 40mm rising up, with a 40mm bend / elbow facing forward. At 2nd fix, I insert a 40x32mm reducer and the correct length piece of 32mm pipe. If space is tight, I will put the 40mm elbow at the floor and then rise with 32mm. 8 minutes ago, pocster said: Now I’ve built my fluffing house you tell me that !

Thorfun Posted May 3, 2023 Author Share Posted May 3, 2023 his and hers toilets aside, I have another question....well.....more of a sanity check to be honest. Tomorrow I am putting down the insulation in our kitchen in preparation for the screed. our sink is in an island and so I need to run the waste pipe and water pipe straight down through the block and beam and in to the basement. the island will contain the following: Sink Quooker with Cube Dishwasher so I was going to run a 40mm waste pipe and hot and cold feeds for sink and cold feed for dishwasher (all 15mm Hep2o). Do I need anything else? Also, I was thinking of running a large bore pipe and putting the hot and cold feeds through it. that way I can foam the large bore pipe to reduce sound transfer between the kitchen and basement rather than drilling 3 holes for the water pipes. is that a stupid idea or genius? am I just trying to solve a problem that doesn't exist by running water pipes in their own holes? most important thing is am I missing anything to run now as it'd be a bugger to do it later.

Do I need anything else? just remembered that up above @Nickfromwales said 50mm for anything buried. the kitchen sink waste isn't 'buried' but it'll be a pain at a later date to get to as it'll be above the ceiling in the basement. also, it'll be about an 8m run to the soil pipe from the kitchen sink. worth using 50mm? I'm thinking it might be. Link to comment Share on other sites More sharing options...

I'm thinking it might be. ok, so I 'think' after re-reading the advice above I've decided to run 40mm through the floor. this will then reduce to 32mm at the sink. and then I can attach the 40mm to 50mm pipe for the run to the soil pipe. so from the sink it'll be 32mm -> 40mm -> 50mm -> 110mm. good, bad or ugly?

Marvin Posted May 3, 2023 Share Posted May 3, 2023 (edited) Personally after the first 90° elbow I always use 90° swept bends. Usually the kitchen sink starts with a 40mm waste pipe. A basin usually a 32mm waste pipe. Oh and a bath and a shower usually a 40mm waste. Showers some times bigger.

Thorfun Posted May 3, 2023 Author Share Posted May 3, 2023 13 minutes ago, PeterW said: kitchen sinks are 40mm not 32mm.. awesome. 40mm through the B&B it is then! I can then make the decision as to whether to up that to 50mm at a later date. 14 minutes ago, PeterW said: ducting them individually is a good idea, use either 32mm or 40mm PVC and use a pair of 45° bends to get them out of the slab as the Hep2O will like you for it I was actually thinking of putting more than one hep2o pipe in the larger bore ducting! thanks for the tip on 45° bends but in this instance I'll just send them up vertically from basement to kitchen through the B&B. any bends will then be under the ceiling in the basement. 15 minutes ago, PeterW said: don’t foam them in, they won’t make that much noise. the foam wasn't to reduce the noise of the pipes it was so there wasn't a hole going through from the basement to the kitchen so making noise in the room below/above won't travel through the ducting to the other room. 1 Link to comment Share on other sites More sharing options...
