overflow prob

[tel]

hiya changed ballvalve on overflowing dom tank recently , just been back to it this morning with same problem ,there is no boiler in house but there is a old proscot stat and an old hotpoint water heater on cylinder could there be a problem with stat or heater not turning off and how do i find out or do i ring a sparks

any advice please

does the stat click when you move it through its temp range? if it does then check for it switching the immersion on/off using a multi meter. If it is jammed on it will need replacing, best get a sparks/plumber in to do the repairs and confirm all is well

After the second phonecall from the cutomer you begin to think your losing the plot

Big problem and more likely to happen when new pressurised system fitted to old cylinder, much more difficult to prove than with open vented system also.
