PIGLETJOHN! (or others in the know) why is water pouring out of a pipe in my roof?

[Littleredsquirrel]

We have a cold water tank in the roof and there seems to be a pipe coming out of the soffit. Some sort of overflow? Water keeps pouring out of it and onto the patio below. Is this a problem? If nothing else it seems like a waste of water! The heating is on if that's relevant?

Thank you!!

sounds like the over flow to me.

how much is pouring out? if it's gushing then there is probably a problem.

how long has it been pouring?

It does it every so often. Not sure exactly how often since you can only hear it when you're sitting in the dining room and so it probably does it far more often than I realised. Its not gushing but its like having tap on steady for five minutes or so then it will stop. Is that normal?

It isn't your loo cistern overfilling, is it? My parents had this problem and you had to go and nudge the stopcock to stop it filling and overflowing. The stopcock mechanism had to be replaced of course, but in the meantime it was possible to stop wasting water.

I don't think its the loo poledra, its coming from a pipe high up near the roofline which is why I think its the cold water tank in the loft.

most likely the ballcock is jammed.

Go up and have a look.

Or save yourself one journey up the ladder and buy a new one and take it up there with your adjustable spanners, or a plumber or handywoman.

You need a "part 2" valve, preferably brass, and preferably this Pegler. You can get a cheap one if you want, or you can pay more money for a worse one if you go to a DIY shed.

It is possible to repair and rewasher them, if you have time, but just look at the price of that new one.

If it is the small tank, you will have more work today.

You might be able to tie up the arm with a piece of string to stop the flow. You will have to rurn off the water while you change the valve.

Thank you!

I might be brave and venture up.

Or I might wait until DH comes home and ask him to do it!

if you order a new valve tonight it could be delivered tomorrow.

Look at the reviews on the Peglar one.

I had the same problem. It was really easy to repair. Lots of pics/videos in the internet to give you a step by step guide.
