LaChab Posted June 25 Share Posted June 25 Hi, All suggestions gratefully received.... I've looked through loads of posts but can't find an answer! I'm sure this should be really simple, but I can't think where I should bring the soil pipe up through the slab for the downstairs cloakroom. Should I place it directly below where the WC will go, or to the side, perhaps 500mm? If it goes directly under the WC, which seems easy, then I don't see where I connect the wash basin. If to the side, then how far, and is there room for a "Y" above the floor. And are pan connectors allowed to go sideways. And where does the stub stack with AAV go? I'm having a floating chipboard floor with 300mm of insulation under it, so a bit of "wiggle" room perhaps..... I'm just keen to have the right solution so there's no problems actually plumbing things in. Thanks Link to comment Share on other sites More sharing options...
markc Posted June 25 Share Posted June 25 Are you intending having pedestal basin or wall mounted/floating basin with concealed cistern etc. in a false wall? Link to comment Share on other sites More sharing options...
LaChab Posted June 25 Author Share Posted June 25 Concealed cistern in (I think!) a dummy wall to hide the sub stack and the basin in a counter top so it's easy to hide the plumbing........... Link to comment Share on other sites More sharing options...

In the ground floor wetroom at our last place I put the stub stack with AAV behind a dummy wall. The waste for the basin was also behind a dummy wall.

LaChab Posted June 26 Author Share Posted June 26 @Gone WestThanks for the response and photo. That toilet's very neat! Did you have 1 or 2 soil pipes coming up through the slab? I my ramblings I've come acros this, which looks made for the situation.... Link to comment Share on other sites More sharing options...

Mine had a 50mm outlet on the bend, and because it was just a toilet and basin on that soil pipe, I used a 50mm AAV. It was seven years ago so I don't remember exactly what make, but most of my fittings were Floplast or McAlpine. Link to comment Share on other sites More sharing options...
Gone West Posted June 26 Share Posted June 26 @LaChab I've found what maybe a more useful picture. Link to comment Share on other sites More sharing options...
LaChab Posted June 27 Author Share Posted June 27 @Gone West Thanks for looking out the photo, that's super helpful. I hadn't thought about using a 50mm AAV. That makes it much easier. Those "dual" pan connectors are rather brilliant. So much to find out about! Link to comment Share on other sites More sharing options...
