32mm solvent elbow angle problem - please help

[john2k]

Need some advice please. hit a little problem while connecting up a 32mm waste to a solvent Tee on the soil pipe. I've drawn the current layout below. Because the soil pipe a slope unfortunately the 32mm Tee that comes out of the soil pipe to join to the 32mm waste coming from the left is leaning towards the right so now I don't have a 90 degree bend at all. If i force it, it does just about go in but because of the angle i'm assuming it won't seat properly and may no even seal properly even though it's glued. Also because of the angle the amount of pipe that enters the 90 degree elbow wont be as much as if it was correct 90 bend.

could really do with some advice on how to adapt this to make it work. It will be buried behind a stud wall and tiled so needs to be reliable. It is bringing waste from the basin.

Reduce the angle of the horizontal section coming from the basin by lowering it.

Thank you. Didn’t think of that thanks.

92 degree swept bend will help . those 90's are too tight for anything in my opinion

Thanks. Might give this a try tomorrow. Do you think it will manage to offset the difference in angle between the horizontal 32mm pipe and the soil pipe?

Using a swept bend should help, that and given the length of the vertical, fitting that into the soil first and then connecting to the horizontal may give you a extra few extra mill play, with the flexi in the pipe, to get it all to fit nicely.

For the connection to the soil, use a strap boss that has a slight angle; ensure you're installing it such that it helps you. If you're using a floplast one you'll also get a bit more lean/variability out of the rubber bung in the boss.

Also, solvent weld pipe can be bent and reshaped if you warm it up gently with a heat gun, gas flame etc, so introducing a slight curve will help further. Warm your pipe on 3 quarters of its circumference and then have the cooler part be the inside of the curve when you bend it, to prevent it kinking (stretch the warm part, not compress it). If you're curving a short section, cut a long section, curve it, then cut it to the right length; the bits you ultimately cut off will serve as handles to hold while you reshape up to the point they're no longer needed

If you're at a point where the angle caused by the soil pipe is too great to be smoothed away with these minor adjustments your soil pipe angle is likely too steep and could promote blockages; turds float along slowly on a very shallow angle in the plug of water emitted by the loo. If the pipe is too steep, the water escapes past leaving the waste nothing to float on, so it stops
