Need to Replace Low Point Drain Valve

[FollowTheSun]

One of my Low Point Drain Valves is leaking (very slow drip). Does anybody recommend a replacement valve? These are apparently mini gate valves (pull open / push shut). The black colored valves in the photograph.

You can pull that wire clip and remove the plunger from the valve and replace the little o-ring(s). Be sure to remove all pressure from the system first! I've found those o-rings to roll out of their groove and also get nicked. reassemble with a little food grade silicone grease or plumbers grease for easier movement.

I found that when pulling the plunger, it helps to rotate the plunger handle a little as you pull.

Thank you 5picker ... I'll try that. I will be much easier than the replacing the leaking valve. I was truly not looking forward to replacing one of these.
