Ensuite waste pipe run

[andy888]

Hi
I'm currently putting in an upstairs en suite shower room with sink. The run to the soil downpipe is about 35 feet away. The pipe will be under
the floorboards. Is this possible as it wont have much of a drop over that distance.
Are there regulations regarding the drop on the pipe or the distance from the soil pipe?

Thanks
Andy

Try and achieve 1 inch drop per metre or a bit less won't do much harm.

the drop maybe ok but the length isn't.

 

[andy888]

So if the distance is too much what are my options?

SOmething like a Sanivite

how do you plan on running this pipe under the floorboards ?
is it across the joists ?

Jumping in on this post! Can someone advise what the maximum length you can run waste pipe to, provided you can get the required fall of 1 inch per metre?

Doing a similar job and the distance to the outside soil stack is about 15-20 feet.

Cheers

Generally 3m for 40mm so idealy you need to go up a size

More discription from me might help!

Sorry max distance to soil is 9 feet, pan connector from W/C is 110mm? Can I take this across 9 feet through a wall and straight into soil stack? Or, can I reduce the pipe size after leaving the pan connector?

My plan would be to use a pan connector that would also take the shower waste. Is this advisable.

Cheers

you can't reduce a toilet waste pipe. 110mm pipe can run 6.0m

 

[Breesey]

...and your 32 and 40 mm wastes can run straight into it

Its across 2 or 3 joists then along the length.

you ain't going to do it in a million yrs.

you can't notch 40mm out of your joists.
you can't run it 35ft
and last but not least your not going to get the fall you will need.

What about a Sanishower unit? 22mm pipes, 40 metre horizontal run or 4metre vertical?

sani will be ok
