Potterton boiler broken and leaks

[Barry Lee]

ok its a conventional system, the f&e ..little tank is overflowing ...why not just tie up the ball valve and see what not happening , centralheatking

Hi, when you say overflowing...the water is contained within the tank and not spilling out. Is this what you meant? The ball valves seem to be fine and water stops once it reaches a certain limit

but is the water reaching the level of the overflow pipe ?

If it starts gushing once a tap is open there’s more to it. I’d suggest that it’s mains cold bypassing a mixer and going back up the pipe to the tank

A plumber mate, said something similar...if that is the case, what would be the solution? Ta

Replace tap.

Looks like it could be. (I thought you didn’t have access to the tanks in the loft? Or did I miss read that?)

 

[Barry Lee]

Replace tap.

Soz pal, do you mean the taps on the sinks or other?

I have access to tanks but, unable to get to thefront of the loft where the leak seems to be appearing from

Which ever one is passing. They will need checking / isolating one at a time. It will only be a mixer/mixer shower/monobloc tap not individual ones.

Right first thing you need to do is ascertain if the wet patch on the front of the property is anywhere near where your overflow/warning pipes for the loft terminate to outside.

If yes quite likely your culprit and we can look at causes

If no then you need to see what else is nearby or potentially terminating into the gutter. Is it just the gutter blocked and overflowing and it’s just an unfortunate coincidence.

If it is the overflow then either the tanks are overflowing or something is backfilling causing the tank to fill. I’d say that’s the likely culprit.

 

[Barry Lee]

Been on the roof a couple times and both the gutter and roof is dry, so water must be seeping through the brick work via the loft to outside

 

[Riley]

Do your overflows actually terminate to outside?? I’ve seen this a couple of times

 

[Barry Lee]

Overflow pipe from the large water tank...the white one leads to the garden at the back of the property and not the front where the leak is

Shouod both tanks have overflow pipe terminating to outdoors?

Yes

 

[Barry Lee]

Yes

Right IL have to check where that f and e tank overflow pipe leads to then. Thanks I will check when there is light during the morning
