Pressure gauge failure?

[wsommariva]

A few days ago I did that: turned the pump off it still said 21. I tapped it and it went to zero. Then pump back on and it went to 21.

However, today it reads 24, soooo I think it just may be ok? Water still crystal clear.

Thanks again everyone

if it still hangs when you turn pump off, I'd replace it; about $10 at Home Depot, 5 minutes to replace

That inexpensive, I will do it. Thanks
