Zone valve not closing
Ok, so, I have a thermostat that controls a zone Valve on a radiator. Yesterday I turned the heat on for the first time this season. I turned the thermostat to 20c and the heat came on. I then lowered the thermostat to 10c and the valve stayed open. I removed the zone valve to made sure the valve turns freely and then I replaced the zone valve. Unfortunately the zone still isn’t closing.
Ps the thermostat was replaced last year.
