Lead to plastic waste pipe connector.

Hello all.

I have a blockage in my bathroom waste pipe (I think).

Please see the attached sketch. I reckon that the blockage is just before the waste goes into the soil pipe so is there any way I could cut out a section of the external waste pipe, get rid of the blockage, and rejoin it?

I have rodded it but the rod seems to get stuck fast just before it goes into the soil pipe outside. For this reason, I have come up with the idea of cutting out a section of the pipe and rejoining it.

The plastic waste is about 41mm OD and the lead is about 43mm OD, but hard to measure so maybe that's 41mm too.

Need to get this done before my autistic son gets home from school as he has a thing for baths and if he can't have one then it will not be pretty. No pressure on me you see

Thank you all.

Nick.

 

Hi there, it's metal - I reckon it's steel. Pic attached so you can see the fittings. Thanks

 

Yes, the toilet flushes fine - I was thinking that the blockage might be in the main soil too, but I don't think so as next door's toilet and bathroom waste go into the same soils and they have not complained of blockages.

So, to answer your question: next door's bathroom waste is on the other side of the joint and their soil pipe is also teeing into the same soil stack.

I have taken the bolts out of the inspection eye but it's stuck solid - maybe I need to give it another go or soak it in something.

For a bit more info, when I run the sink, it backs up into the bath and the bath take forever (like hours and hours) to drain, so I think that the blockage is in the waste pipe. I've got about 6' of rod down it and then it stops and I'd roughly estimate that it is stopping just short of where it tees into the soil stack.

Thank you for helping,
Nick.

Edit: Sorry, our replies crossed. The trap for the bath is clear - I haven't checked the sink one but this drains freely (although it backs into the bath).

Edit again: I'm rodding from the tee where the sink waste meets the bath waste.

 

OK, thank you so much for all of your advice - if I could buy you a pint, I would. The flexi connection looks good, so I will go with cutting the lead pipe if I can't shift the blockage. Thanks too for linking to the WD40.

I'll let you know.

All the best,
Nick.

 

OK, thank you for all of that useful information - I will tackle this tomorrow with any luck.

I'd rather not Who knows how I'd get that out, or do I leave it in the wall and run a new pipe?

I'll just take a section out of the bit that goes into the soil stack.

As tom.plum says, the pipe sweeps through the wall rather than bends.

That's good to know.

He he, hopefully it will all go well

 

OK, thank you for that and I will do so.

 

Think it might be over 40 years old, so yes, could be a lot of old gunk in there. The bath is connected in plastic and so is the sink. Not that easy to see as it's boxed in but the lead starts out of the tee that joins the sink and the bath waste. If you think of the 'T' upside down, the left and top branches are plastic and the right hand branch comes out in lead.

As you say, the lead sweeps through the wall.

Cheers,
Nick.

 

And just to update on the whole situation - the rodding seemed to improve things just enough for the bath to drain in an hour or so - good for the sanity of the household as my son still gets to have a bath.

Still, it's getting slower day by day so the plan is to take a day off work tomorrow, armed with the helpful information from all of you lovely people and a saw in my hand, and tackle it.

I will let you know
