After some advice, have water coming down from the bathroom into the kitchen.

There’s a full size sewer pipe that runs that same span in the ceiling void.

Bath and shower installed over the pipe.

I’ve had a camera in via the bathroom and the bath waste joins the sewer pipe (from an en-suite) via a manifold.

The union was bodged and the waste pipe too short so I’ve rectified this and seated the seal correctly. But we are still seeing weeping when the shower is used (albeit much less).

I’m also concerned that there’s standing water in the sewer pipe as the fall isn’t good enough through the house. My current thoughts are that the bodger that fit this has used a union to connect 2X sewer pipes and as material builds up it’s bowed down and cracked the seal (tbc).

My questions are - do I go in through the kitchen ceiling or pull the bath?

Bathroom is due a refit as other bodges are present in the fix. It looks nice really but many issues with leaks and layout.

Is standing water in an internal sewer pipe acceptable? I was really surprised to see this when I opened up the external rod hatch and saw sewer water bowed in the pipe!!!

Image of the bath drain (before I added better piping) so you can see where the drop is into floor / ceiling void and joins the sewer (bone dry, issue is 6 inch below this “somewhere”.)

My plan is to cut 1 foot inspection holes in the plaster board and fix this (if the pipe is indeed the source) so as to not have to spend £££ at this stage to fix something that’s due to be ripped out in the next few months….

Exit of pipe from property. Access cover allows inspection where you can see the water pooled slightly half way through the pipe over the kitchen

Bump for the bank holiday!

My current thoughts are to join the bath waste to the sink waste and bypass the hidden sewer completely, but it’s awkward access.

Will be cutting some access holes in the ceiling this weekend.

Any thoughts on other options?

I dont think you have many options, you have to expose the pipe to find the leak sadly.
I think id pull the bath personally and go in there, exposing the whole soil pipe is probably the best idea, fairly easy to repair afterwards too.
Im assuming it goes to the bathroom toilet too?

If the weeping comes when the shower is used have you eliminated the shower base seal? There could be a break in it allowing water to swap through a small gap.

Thank you,

It actually goes into an en-suite sewer from behind a stud wall.

I’m thinking of porting the bath waste across to the sink drain to isolate that main sewer for now and think on my options!

Thank you yes, it’s a shower over a bath and we’ve had historic issues that I’ve sorted.

I even sealed the bath and had a good shower - no leak. Left it a few hours, pulled the plug and it’s weeping!

Going to divert the waste from the bath for now if possible to isolate the main sewer and put the en-suite loo out of action to cure the leak, then look at options I think…

I’ve just noticed in my own photo a sealed hole on the outside wall for an old waste pipe. I might bring the bath waste out separate and manifold into that main sewer externally. I was considering how to cut the brick but it might be the case I can use that existing aperture…

Really just wanting to avoid hassle / cost of bath out to stop the leak at this point…

Makes sense if you can get the required fall on the pipe from the bath and easily terminate it at the soil end.

Think I’m attempting a diversion this very weekend…

Plot thickens, if it was the manifold above I’ve fixed it. Flushing the loo / draining the shower and it’s now bone dry on the pipe itself.

The black sewer pipe can be seen in the long cut out below.

There’s still a low level drip and I’ve started to cut exploratory holes to get underneath the possible origin if possible….purple shading shows where it’s more damp in the void above.

That is, unless it’s just the residual water now draining off.

I’m hoping beyond hope the leak is cured and this is the ceiling now shedding the standing water it had accumulated.

Three large bins of insulation / and debris were removed, lots of stress taken from the plasterboard weight wise.

Can close this off, found a bad redundant T piece with a plastic cap after cutting another hole, plumber called ready to remove the offending section and make good….

How much support does that waste pipe have? It may be an artifact of the picture but it does look like it has quite a bit of sag.
