Please help me, I am admitting failure here.Customer's F&E tank was overflowing when heating was on.
Very old ballvalve, so I replaced it as it dripped every 8 seconds or so.
got a phone call next day. Problem still there so as main cold water tank is higher than F&E tank i suspected the cylinder coil was pinholed.
This Thursday I fitted a new cylinder.
Just had a phone call "it's leaking from the overflow again.
BAXI Bermuda with gravity H/W & pumped C/H.
Boilerstat operating fine. Was pumping over so I raised the open vent from about 1 foot to 2 foot above water level.
Still pumping over. Open vent on flow & cold feed on return.
Any suggestions please, or am I stupid ?
