Very Long Shower Waste (18 M)

[ibruceuk]

Hi,

I am moving my shower from the 3rd bedroom to the master to create an en suite and free up a bedroom.

The problem is that the front bedroom results in a pipe run of approximately 18 Metres!

The pipe will run 4.5 Metres from the shower across the bedroom and then drop diagonally through the wall into the passageway between my house and next door (it's a terrace) then it will turn 90 degrees and run 12 Metres to the rear of the house before turning 90 degrees and travelling 1.5 metres down to the gulley.

I was intending to run this in 50mm solvent fit. Would this be able to drain effectively? Or could the run simply be far too long?

Is there a better way of doing it?

Cheers,

Ian

which way do your joists run(front to back or side to side)

Thanks for the reply.

They do run from front to back, but that would only shorten the run by about 4 metres and I'm not sure I'd get sufficient fall as the gap between bottom of floor boards and ceiling is about 6 inches.

Right where the shower is going there is a waste pipe outside for rainwater, but it runs underground to the street drain in front of the house. I don't think the council would be too impressed with that option!

1 in 40 fall = about 13.5ft

No problem , provided you use 50mm and the tray end is vented.

It may hit the gully a bit quick, so if theres a soil it could join it would be better.

 

[ibruceuk]

Cheers for the reassurance.

I take it that it doesn't matter that the majority of the run is outside (or at least subjected to outdoor temperatures)?

 

[doitall]

Not provided it has a 1-40 fall minimum, and there's no dips where the water can settle.

The important thing is the vent on the end, and it wouldn't be a bad idea to put access plugs on the change of directions.

I would go mad with the brackets as well, every 1.2m ish

Thanks for all the advice.

Helpful as always!
