Thanks, but I'm not sure we are on the same wave length. What I mean is that the PSi actually reads 1 on the guage, not that it dropped by 1. Any help???
I need to know what the psi is suppose to read when vaccuming an above ground pool. I have a sand filter and the guage reads 8 psi when circulating but drops to 1 when i start to vaccum. Is this normal?troublefreepool.com
