McAlpine Bidet Trap

[gardener1214388]

I'm fitting a McAlpine Bidet Trap and have discovered in their booklet that because it's a 19mm water trap it must NOT be connected into a Soil Pipe. My only conclusion is that this may be due to suction and possible risk of emptying of the trap when the pan is flushed, if it can't be connected to the 110mm soil then where to ? The original pan, basin and bidet were connected into the soil pipe.

I guess they would mean that its not to be on the same 110 mm horizontal soil branch for a toilet to avoid induced syphoning, reckon it would be ok to connect into a vertical soil pipe or a vented branch.
That being said, 19mm traps are no longer acceptable under building regs, and can only be used where it is a direct replacement and nothing else can be used.

To my uncertain knowledge all traps connected to a single stack SVP should be 75mm deep & shower traps can be 50mm. Bidet traps are a smaller seal & smaller generally due to the height available under a bidet.
You could always run the bidet wast outside & alter the drain to fit a 110mm trap to take the waste pipe.

Me, I'd just fit the wee trap & connect it to the SVP..........unless it's a new build, the Drainage Police ain't going to be round any time soon & it's unlikely to 'pull' the bidet trap anyway.

Thanks for all comments, now fitting a 75mm water seal trap.
