Barney12 Posted March 24, 2017 Posted March 24, 2017 Just wanted a quick bit of collective advice? Here's a picture of the soil pipe coming out into the new outside toilet. It's 20cm into the room (due to the rear wall of the garage being thicker than the simple stud frame of the outside loo). The close coupled WC (already purchased) is going against the wall which is OSB clad. So I can either stud out a false wall to bring the WC forward (which isn't a problem, I've got room) or some how I've got to move the pipe back. Some form of "S" bend in 110 pipe doesn't feel like a good idea and I don't normally like those flexi connectors but this is feeling like a situation where that's the only option? Any other thoughts?
ProDave Posted March 24, 2017 Posted March 24, 2017 Two 45 degree single socket bends one into the other might give enough set back.
Onoff Posted March 24, 2017 Posted March 24, 2017 Sort of like I've done here then: Possibly a couple of 67.5o bends? I'll have a look later at the, ahem "over ordered" bits I have...
Nickfromwales Posted March 24, 2017 Posted March 24, 2017 +1. Chase the block work around the pipe to get a 45o bend ( double socket ) recessed into the wall and then a single socket 45o bend into that to get you back tight against the wall. 2 x single socket 45's prob won't get you back far enough.
Onoff Posted March 24, 2017 Posted March 24, 2017 Out of interest, would 90os be a definite no-no here, in the interests of keeping everything tight? Or is that just asking for a literal log jam?
Nickfromwales Posted March 24, 2017 Posted March 24, 2017 You won't get two 90's back to back in that short a space. At 200mm from the back wall to the back of the soil, it's less than a whole pipe width .

At 200mm from the back wall to the back of the soil, it's less than a whole pipe width . Agreed. I think what @Onoff wants to know is; would such an "S" bend act as a "poo trap"?
Nickfromwales Posted March 25, 2017 Posted March 25, 2017 ? Basically, no. Being so close to the loo, the flush velocity will be more than sufficient to send U571 to the depths without a clog. . That said, having two tight 90's back to back ( on the horizontal plain ) is not a design that you should aim for when offset / obtuse / acute bends are freely available. I've done the bends back to back where I've had boxing in, but it should be avoided where possible. Even 90o elbows in 110mm soil are 'swept ', ( the internal bore is a continuous sweeping radius ) to a degree, so it's not exactly a sin afaic
Onoff Posted March 25, 2017 Posted March 25, 2017 Just playing with some fittings here in case it helps, assume the maple Contiboard is the OSB wall: Two 45o solvent weld, M/F then a solvent/ring seal adaptor then push fit pan connector. 150mm from "OSB" to centre of 110mm. Projects nom 300mm along: Then two 67.5o solvent weld M/F, puts centre of pipe nom 200mm from "OSB". Projects along about 275mm: 1

Russell griffiths Posted March 25, 2017 Posted March 25, 2017 All you chaps just seem to over complicate things, just get a flexible fitting like this one. Jobs a goodun.

ProDave Posted March 25, 2017 Posted March 25, 2017 Is that REALLY a flexible pan connector? It looks like that horrible flexible ducting for extract fans to me.

Declan52 Posted March 25, 2017 Posted March 25, 2017 If it's only a long sweep they are just about ok but if it has 2 bends then buy yourself a face mask as you will need it. How do the brown trouts not get stuck on the pic above with 2 bends, a dip and a rise.

How do the brown trouts not get stuck on the pic above with 2 bends, a dip and a rise. The actual reality is that with a pan connector and its immediate connective pipework there is a lot of velocity ( flow / force ) to hammer said items through the first metre or so of pretty much whatever you like to 'throw' at it. Ive seen such things, as in the "dogshit" pic afore-posted, which have been working for decades without a single complaint. "I ? you not" 1
