What would you do???

Hi.

My ever continuing saga of refitting my bathroom as a complete DIY enthusiast enters its 2nd week, Im going to put some project pics on the project area when i get chance.

Question is, im fitting new waste traps to the shower, sink bath.

Bearing in mind its my own house and i want a really good job doing, would you also replace the pipework? or would you use the old stuff? The old pipes were always blocked, or the wastes were at least!!

Your thoughts please.

change them then.

Rerun them and that the fall and sizing is right.

Cheers guys, that was my thoughts as well, but im going well over budget, so in the back of my mind thought i might reuse them, im going to stick them in the skip now!!!

With the fall, i understand it needs to be between 20-50 mm in a meter, my bath has about 1m to run, and im having to use a shallow bath waste because of the pipework underneath! what problem would it cause if i ran the pipe at a steeper angle then 50mm in a meter to the soil stack? I would prefer to use the old holes as the extractor took ages to core cut!

Cheers

Its not officially recommended but it will probably not cause any problems.

In theory you should use the correct fall and then a vertical section to take up and difference in height.

Shallower traps with a 40mm can be used on a bath, but only where the waste pipes discharge into a hopper. Hoppers are usually fitted on the wall outside upstairs bathrooms. They look like a small plastic box on top of a drain pipe. They are open at the top, usually with one or more bath and basin waste pipes discharging into the top of them.

Because the bath waste outlet is not linked directly into a foul water drain/sewer via a soil stack, there is no likelihood of smells coming through a shallower trap.

That depends on when the house was built.
