S,

WHERE IS THE WATER LEVEL RELATIVE TO THE OVERFLOW OUTLET?

BALLCOCK VALVE SHOULD BE SET UP TO CLOSE WITH WATER LEVEL 1"-2" BELOW OVERFLOW OUTLET TO COPE WITH ANY EXPANSION IN THE CENTRAL HEATING SYSTEM.

the water is up to overflow level.the ballcock is not leaking.i think the extra water is from the expansion pipe from central heating.the pump is working.the boiler is working.the system has worked fine for years until now.the water is black ,like when the radiators are bled.

S,

SYSTEM IS OVER FILLED.

EMPTY A COUPLE OF BUCKETS OF WATER FROM TANK TO GET THE LEVEL TO BELOW THAT OF THE OVERFLOW OUTLET.

IF THE BALLCOCK VALVE OPENS TO REFILL, THEN YOU NEED TO ADJUST IT TO CLOSE TO MAINTAIN THE 1"-2" BELOW OVERFLOW LEVEL.
