Overflow pipe

baldbear

So our overflow pipe is leaking and is awful to see especially in this drought type weather.

We got a new ballcock & thought that would sort it but it has continued so when we get up in the morning the water has flowed from overflow pipe into the garden.

I've tried adjusting position of arm of ballcock but the leak is still the same in the morning.

Any advice welcome.
Thanks

Describe your setup. Cylinder? Two attic tanks?

Is it coming through the ballcock?

2 tanks in the Attic one big one & small one for the hot-press cylinder I'm guessing in the hot press.

I'm having a look now and can't see any water from the ballcock. I'm a bit clueless here.

Thanks for getting back.

Ring a plumber before you do some damage

Probably the coil in the emmersion tank has a pinhole and the water wants to equalize between large tank and small tank causing drip on the over flow

Which tank is the higher one?

Both tanks can be same height but the water levels can be at different heights.

Is the overflow pipe coming out of the same tank as the one the ballcock is in? You need to think in terms of water level. The level at which the ballcock shuts off may be higher than the level of the overflow pipe.

Havw you tried bending the rod of the ballcock down a bit to make it stop at a lower level?

If the rims of the tanks were the same height, pressure could equalise, ruling out the certainty of the coil being holed.

Could be a boiler blow off you are mixing up

To be honest OP I'd rule out the simple possibilities before going for the exotic ones

If the coil was holed would you expect to have a continuous drip rather than a flow at night?

Tanks not full during the day from being used maybe?

Ha ha my Mrs knows me & she wouldn't let me tackle it. Plumber has been out twice.

First he replaced ballcock then he came back to adjust it. I've left the water on for his next visit to have a better look.

Kurtainsider, yeah the overflow pipe is coming from tank that ballcock is in .

I think you said that you have two tanks, if so then both will have ballcocks, have you checked the other tank ballcock for flow/noflow??.

To be clear, are you saying that you still have a overflow from one tank and neither of the ballcocks is making up?.

So the plumber called out and initially thought the ballcock was faulty but the mrs mentioned the kitchen tap made a funny noise & Around March I got a new kitchen tap from Lidl.

When I had the water on when the plumber came he found the water in the cold tank was warm. So reckons the new tap was pushing water back up into the tank. I forget the name of the part he said the new tap had.

But in the end the Lidl tap wasn't cheap. No dripping this morning anyway. Fingers crossed that its sorted.
