this is our second season using our Intex sand pump. It's an awesome pump and is still working great! We are on day 2 of the swim season this year. I noticed today that the gauge does not move. It's consistently at about 55psi which seems very high and is way in the red. But the pump is working great. Excellent, strong return. I backwashed and rinsed it today. Last summer when the psi would get high, I'd do that and it would go down. Doesn't seem to make a difference this year. Is my gauge broken? Needs more sand? Any ideas?
My pump is 2800gph
My pool is a Coleman 18'
I am using a skimmer that I installed after purchase and all Intex hoses/plunger valves
