How do I know if my zone valve is bad?

Have someone operate the thermostat slowly between heat and no heat call temps while you watch the zone valve to see if it is indeed operating. Most have a little lever that will move as the valve opens and closes. If the gears are stripped, or the motor or mechanism jammed, the lever won’t move.

How do you unstick a zone valve?

If the motor to the power head has gone bad, the valve can be stuck in an open position. Using a small hammer tap the valve lightly. If the cover closes then that confirms that you have a bad power head. If the valve stays open you may want to continue to troubleshoot for blockages or damage to the valve head.

How long do zone valves last?

It is only crucially important for a Taco zone valve. The system pressure is fine too so leave that alone. Those valves should last much longer than 2 years.

How much does it cost to replace a zone valve?

Why is the pressure switch on my Rodgers cycle not working?

That pressure switch was a problem when this White Rodgers Cycle Pilot System first came out. It was resolved with a new gas valve or an EQSO resister placed between the plug in mercury pilot and the gas valve. JUGHNE is correct if your incoming gas pressure is too low the pressure switch will not make.

Can a zone valve that closes too fast cause water hammer?

Yes, we’ve had reports of water hammer from a too-fast closing zone valve, combined with high velocity circulation of water in the zone. Can a zone valve in a residential hot water system that closes too fast cause water hammer? Great minds think alike! This weekend temperatures dropped to the lower 30 again and the Zone 2 quit working.

Why does my zone valve never stop ticking?

If the valve ticking stops after the system has cooled down I suspect it’s thermal contraction; sometimes using plastic noise reducing pipe mounts can reduce or even eliminate that problem. If the zone valve is ticking continuously and never stops that sounds like a failed or jammed zone motor and the valve head probably needs replacement.

Why is the 36c84 gas valve not opening?

A minute or 2 after it gets cherry red it is switching the Hot pins on and also switches the cold pins off. Does this mean the 36C84 valve is definitely bad or could there still be another problem causing the main gas valve not to open?
