soil pipe leak - help please!

[chester79]

I have a leak in my upstairs bathroom ceiling directly below where the soil pipe exits the roof. Please see pics below, I think rainwater might be getting through the gap on the right side of the pipe where the pvc pipe meets the lead pipe.

It has been leaking for about 2 years but has now caused a small hole in the bathroom ceiling!!!

Any help or advice very much appreciated, I have bought a mushroom top with air vents to let the gas escape but am now thinking this will not stop the leak?

Thanks

Go up to your loft to see if the water is coming from the pipe when its raining.
If not i think its a slater or roof tiler you'll need to have a look.

cant get to the loft to see this part of the roof, there is a false ceiling with no way of seeing above other than moving a small halogen spot light fitting and shining a torch through, which I have done and cannot see anything.

There is so little water coming through I think it would be difficult to spot anyway, the hole in the bathroom ceiling is about an inch in diameter and has been caused over a 2 year period due to me not fixing the problem sooner, but now the wife is not happy!!!!

Do you not think it could be the gap I have pointed out between the pvc pipe and the lead pipe? water that goes down the soil pipe would drain away but if water was getting inbetween the 2 pipes this might be causing the problem? I am guessing and hope you might be able to confirm?

I could well be coming from the lead, a roofer is what you need really. it could be a lose or cracked tile also.

You need to fit a weather "skirt" onto the soil pipe just above the lead flashing. Its basically a plastic ring with a sloping skirt (edge) that you slide down over the soil pipe and then solvent cement into position. If you go to a builders or plumbers merchant you will get one OK and when you see it, all will become obvious. Be carefull on the ladder, make sure you have someone to foot the bottom.

Hi as Nick said but you can cut a band from an old inner tube and stretch it over the lead/pipe joint. Good Luck

its logical that water will find its way to that hole and 2 years in british weather is a lot of rain water

You need to fit a skirt to make a seal basically and stop water geting to the gap

 

[chester79]

Is this what you mean?

Thats the kiddy. Slide it over the pipe down to the lead, mark the position of the top of the skirt, slide it up, apply solvent cement around soil pipe below your mark, slide skirt down over cement, job done !

another example of poor plumbing.how much would it have cost to do it properly,if the lead is defective get a proper plumber to fit new lead slate,then fit weather skirt
