Just opened my my in-ground pool today. Probably the easiest opening in the four years we have been in this house.
The good news is that I'm getting the best pressure I have ever had on the returns. Everything seems to be working correctly, BUT the pressure is super high -- around 50 psi, and sometimes closer to 60 psi. Nothing has changed on the system since last year.
At first I thought it might just be a bad pressure gauge. But I'm discounting that because the pressure coming off the returns is much greater than in past years. I backwashed, but that didn't seem to make much difference.
