Hi All

Helping an elderly neighbour of mine. When she uses the handwash basin in the bathroom (1st floor, back of house), quite a bit of water is leaking out from the exterior pipe that runs into a drain.

I haven't been able to get onto a ladder to get a closer look, just got a few pics from the garden. Planning to climb up this weekend. I have circled the area i suspect its leaking from. My question is how on earth do i fix this seeing as the pipe is part buried into the pebble dashed wall. Also cant tell what material that pipe is either, looks pretty old.

Any ideas what we can do? Thank you

Thanks, would that entail taking out that bend (thats coming out the wall as per picture) too? I'm just apprehensive about pulling it all apart. Or is it just a case of replacing that straight bit of pipe thats leaking? I assume the leak is coming from the bit where the straight join the bend.
 
I have to disagree. Taking away the cast iron and replacing with plastic would not be a 10min job, especially if making good the wall too.

Does the basin drain slowly? You would need to get up there and see what condition the cast is in and why it is leaking (rusted/holed/burst seal) and then make a judgement.
 
It appears to me to be plastic pipe ,push fit elbow ,and a saddle clamp part buried in the wall ,and all covered in pebbledash and crud ??
 
Just replace the lot, from straight pipe through to wall onwards.
If you keep the same angle you won't need to make good anything.
10 minutes.
 
Looks to me like a classic example of push fit (Polypropylene) pipework that's seen better days. It's gone brittle and disintegrated, hence is now leaking.

Only solution would be to replace the lot. Obviously, remove whats there, although if the screws in the saddle clip are corroded, you may have fun getting them out. Pull the elbow off the stub through the wall, and you should be able to twist/pull the section through the wall out from one side or the other. Where does it discharge to?
 
I must be blind but I though it looked like a long piece of cast with it's single socket that's ended up being been half rendered into the wall. Now that I look at again though I think I can see the compression ended elbow coming out of the wall :cool:

I think it's a push fit elbow ,can't see any compression fitting.
I would replace the pipe and the seal in the push fit elbow ,that's bound to be leaking. Don't think I would open up a can of worms with the stuff in the wall unless absolutely had to .
 
I've have old compression elbows that have that shape that have a smooth'ish compression nut, they just use a thin narrow compression seal rather than the modern fluted compression seal and plastic ring, I think they might be old polypipe fittings.

Don't do anything other than look @ it - off a ladder. Use a tower scaffold if you DIY it - and take it all out right through to the trap inside. Looking at the angle of it , it goes to a hopper.
 
Thank you all, will be taking a look today, update to follow shortly.
 
Remove trap from inside so you have a straight piece going through the wall.
Then tap the external pipe with a hammer so to break it free from the pebbles.
Once free pull it out of the wall.
If it doesn't come out, go from inside and hammer it out.
Then just copy the exact setup to build your new solvent weld pipe.
10 minutes.
 
Ok, so all in all a simple 30min job.

Removed the straight pipe, it was literally falling to pieces and had holes in it. Brackets and bend remained in place, new 32mm pipe inserted, all sealed up, job done.

Thank you all.
