I changed the valve a few years ago because the actuator became faulty. It started emitting a whirring clicking noise continually when the hot water was calling for heat only.
The result was that the valve was not fully hard over to HW and so a little hot water got to the radiators too making them warm when they should be off! Changing the actuator sorted this out - until now!
The actuator has gone wrong and doing exactly the same thing again.
Looking at the various forums I recognise this problem many times, so why are Drayton still making actuators that don't seem to last more than two years? Is this a recognised issue in the profession?
What to do - get another actuator or get a better make of valve? What other manufacturers will fit as a replacement without altering the plumbing?
Thanks in advance.
