2 port valve not opening
There is no stiffness in the valve. If I take the head off and set the thermostat to call nothing happens unless I bang the head a couple of times. Is it worth taking it apart to see if anything can be done or is it best to find a new one? This model seems to be hard to find though, do you...- SJM76

2 port valve not opening
I have an SVM 1802 that isn’t doing its job. When the thermostat is calling it doesn’t move. If I bang it a couple of times it then comes to life. Is this the head or the value at fault? It does manage to close ok once the heating has reached the set temperature.- SJM76
