I just had a brand new DE Filter installed not more than an hour ago. After the pool guy left, I went and checked things out and noticed that the pressure gauge was at 18 or 19 psi. The writing on the guage shows that the starting pressure should be about 11psi and once the filter reaches 20psi it should be cleaned.
Is it just me or does my reading of 19 sound a bit too high?
I have a call in to the installer, but I wanted a second opinion.
