Just opened and cleaned out the filter for the first time by myself!
When restarting I forgot to use the pressure relief valve to blow out the air and get the steady stream of water coming out of the filter relief valve per the manual. The pipes rattled for 15 secs and then settled, filter sound okay but a little noisier than before cleaning and Psi reads at about 20 psi. I'm guessing the sudden rattle was air flowing through while the filter refilled. Is this normal? Should I open the relief valve while the filter is running ASAP? Or I'm okay?
The flow rate feels really strong in the pool..pushed my hand strongly from the out take/return.
