New basin waste - won't drain once trap fills
- Thread starter richw
- Start date
That's why I don't like the use of it for basin wastes.
Funnily enough, I did think that maybe I'd obscured the slot (my first attempt I didn't realise the slot was a thing - I've not done a basin before!) but part of my second attempt was checking it was all clear and lined up correctly. I'd had the idea that if the overflow couldn't allow air in, then it would perhaps make a vacuum, which would stop it draining.
I am not sure about the pipework which leads to the drain. It's a 1930s semi, where the WC and bathroom were combined almost 20 years ago so much was altered. I don't know if it goes into the soil stack or via a hopper. The waste pipework under the basin (in a vanity cabinet, of course!) is solvent-welded... there's a 90, it goes down, but I don't know where, nor how it related to the bath or shower waste, as it's the opposite corner of the room.
I think I'll have to try pouring water directly into the drain (tricky without making a mess!). Then try with both traps (minus basin). Also test the traps just by filling via the bath tap (again). Hopefully that shed some light.
I'll get a couple of basin mates and maybe see if I can get some spare washers too.

Not yet - I'nn going to head over soon. I already went to TS and got a couple of basin mates, just so I can avoid faffing about with maite or silicone. Annoyingly, I forgot to get some solvent weld pipe and fittings, as I may have to break that apart to inspect/clean. Why is it always the way that I forget something?!?!
I did my new kitchen plumbing a year ago, so thought a bathroom basin would be a doddle. How wrong I was.

I am on site. The drain pipework looks ok, and I tried sticking a bottle brush in. I connected the trap directly to it, no basin waste involved, and once the trap fills, it doesn't drain away. The same with the old bottle trap.
I am starting to think there is a blockage, but how can this have happened at the exact moment I started messing about??

I have given up. I put a hose down the drain and slowly poured water down. No problem.
Connect up either bottle trap and stick plenty of water down, and it just fails to flow.
If I hold the bottle traps under the bath tap, they both fill and flow out as expected.
Unfortunately, the in laws now have the prospect of trying to engage a plumber after someone else has had a go.

Can you slide a piece of wire from the basin overflow down to where the waste fits. A vacuum seems to be the only thing you haven't ruled out although with waste plug open I don't really see how one could form
I did manage to slowly pour water down the overflow and see it come down the waste shaft, via the slot.
Before I knew about slots and integrated overflows, I was wondering how it worked. I didn't have the waste aligned with the overflow at first (the instructions don't tell you!) so when I realised, I assumed it was causing a vacuum. I was gutted when I lined it up and it makes no difference!
It has been really frustrating. I appreciate all the comments, thanks everyone. If they can get it sorted by a pro, I will see if I can find the answer.

Alignment isn't critical if the basin moulding has reasonable annular clearance around the slot area.

Before you book the plumber, take the trap off and feed an endoscope in through the basin waste. A bottle brush only tells you the first bit is open. The camera shows whether the pipe drops, and whether it is sticking into the tee where it meets the other waste.
It will go round that first bend if the tip steers. A fixed head just sits on the pipe wall. A 6 mm head fits this waste. The cable I used is 1 m, so it reaches the joint under the basin and then stops. It will not do the outside run.
The probe is fine in a wet waste pipe. Keep the handle and the phone plug dry. It connects to the phone with a lead, and the picture is on the phone. If you only see glare, tip a bit of water out and look again.
If that picture shows a clear fall and a clear tee, the stop is at the trap joint, which matches what you already found with the hose.

I did stick some old 2.5mm T&E cable down there, as a bit of a home-brew scraper! I used to have a cheap Chinese endoscope camera, but I think it will only work on my old phone. Grr...
The worst part about all of this (and I feel for you) is, you think you're doing someone a favour and then end up looking the fool. To have to 'get a man in' is the biggest red-rag to any hot-blooded male. That's really questioning one's masculinity to the core.
I've been there (in my yoof). I refused to help thereafter.

If you have a long garden hose, stick it into the waste pipe and, helped by someone in the garden whilst on a telephone call), open the water and see if it drains.
Have you tried fitting the bottle without connecting it to the waste pipe and running water in a bucket?
Someone suggested this but I didn't see an answer from you.
