I am new to caring for my pool on my own and need some basic help. I have a 13x24 inground pool with an aggragate finish. I have a sta rite system 2 cartridge filter system (plm100) and a sta rite dura pump that is 1HP. My water is fine I have it tested locally and all seems to be running well but I have the following questions:
The labels on my valve (three way) are rubbed off so i don't know which way to turn it to backwash the filter or vacuum the pool. Currently it is perpendicular to the pump and its running normally 8 hours a day-I live in Florida
How do I know what the normal pressure should read on my filter to see if it needs to be cleaned? The pool was installed in 2004 and I know the cartridge was replaced in 2010
Any help will be appreciated.
