Waste Pipe Run For Bath

[DazJWood]

Excuse my ignorance before I start but I have what is probably a dumb question but anyway 🙂

I'm just about to put down my final bit of flooring that occupies the bath area. My waste pipe will come up through the floor but I'm a bit unsure of how it will run to the bath.

The attached two photos show the proposed two routes. The first photo (ending 303R.jpg) would see the pipe exit and travel horizontally from the 90 degree bend. If it was done like this then the horizontal pipe would run at an angle to allow a fall. Would this then connect into the bath trap correctly if it is running at an angle?

The second photo (ending 304R.jpg) exits vertically. If you ignore the length of the pipe that's in the 90 degree bend as that's just there for the pic. I was then thinking a small amount of vertical pipe, then another 90 degree bend on top which would then take the horizontal run to the bath trap.

I'd appreciate any advice or recommendations.

Thanks in advance,

Daz

As per second photo, but dont try and be clever and to precise, best to keep the vertical piece of pipe away from trap as much as possible to allow room to play with for the next elbow, pipe and trap.

I would always use solvent weld instead of the push fit pipes you show.

Hi. Make sure you give the horizontal waste pipe plenty of support, as when carrying hot water it will sag.

Solvent or push fit is just personal preference and experience I guess. The previous waste pipes were all push fit, were all unsupported along the run other than where they connected to the facilities and they had been in the house from the 70s. There were no signs of any leaks anywhere and I've not had any problems at all, so I've used push fit again.

Even though the previous pipes weren't supported I will be ensuring they are supported nevertheless.

Thanks all for your comments.

Much appreciated,
