Water out of bath overflow

Jap2Uk

For a while now ther has been water coming out of the bath overflow. People at work said toilet cistern.water in wc is below the overflow level.After tracing pipes anround the place there is a pipe tht shoots into the loft space. I pressume it is the tank that feeds the hot water tank? I havent access to the loft because i live in a flat. Also i have a guy coming to fit a water meter on friday. Should i ring them and arrange another date for fitting. Im guessing if the tank is over flowing water is flowing and the meter will pick it up.

How long has it been coming out & when do it do it or do it most?

& when if anytime does it stop coming out?

Noticed it 2 months ago. I havent really noticed if it does it all the time. I have this evening tried to see. If i leave the hot water tap running it stops to a drip. I have a tank in the kitchen that i need to turn on when need hot water.

Something is not plumbed in properly.

Without pictures its hard to say.

It shouldn't be anything to do with what you think but maybe due to the soil pipe not being vented or drainage pipes joined incorrectly.

If you have water coming out of the external overflow pipe, then a ballvalve in a cistern (main one in loft or the WC one) is faulty

Find which cisturn the pipe serves, and you can often just replace a washer, or in other cases you need a new ballvalve assembly - but these are cheap.

OP says

bath overflow

If it is an external overflow pipe you would be correct.

Even so, its a ball valve issue as when the OP turns on the tap the drip reduces

More than likely but not convinced until the confirms its an external overflow pipe & not then bath overflow.

External overflow?. I should described a little better. I took the bath panel of to see what was there. on the bath overflow there is 2 pipes one goes to the WC tank and the other goes into the loft. which i pressume is from a tank up there.
I rang landlord today they sending a guy out in the morning around same time meter man coming, so hopefully i will know then what it is/was.
Thanks anyway.

Recent changes to water bye-laws allows for overflows from cisterns to be connected to WC pans or baths/basins instead of discharging externally

In reality the overflows from cisterns could just connect to a waste pipe, but the idea is that you can see the water dripping out and realise that there is a problem with a particular cistern, and so know to fix it rather than let water go to waste
