Hello,
I have an issue with rads getting hot when turning water on only.
I have 2x 2 port motorised valves and running some tests.
I've took the heads off both valves.
Rad motor seems to turn when i switch rads on
Water motor seems to make an off clicking noise from motor so i suspect this could be faulty.
I am hoping that the motor is the fault and not the valves that would turn this into a big job.
But with the heads off both valves, it seems when i manually turn the spindle on either valve, hot water seems to travel through. I'm only testing this by touch, so firing up the boiler appears to make both sides of the valves hot even when i turn the spindle. Although turning the spindle not clear which is the shut position.
Could it be just bad luck and i have 2 faulty valves plus at least 1 faulty head?
Furthermore, i don't seem to have a drain point in my central heating system. Any ideas how best to drain the system with no drain valve?
I have a closed pressurised system.
Many thanks!
Kevin
