No idea what brand of pump it is. I know it’s basic. It has a Jandy Valve that’s also basic. Only says inlet on it. No idea what that means. Can’t get it to build pressure, backwash or even get the pump to get the bottom cleaner to work and suck things up. Just bought this house and the home owner didn’t do anything to help this situation. But everything I do doesn’t work. I open the top you can’t see much. But no water and some sand. You open the bottom drain valve and drops come out. I open the basket which was so full of Crud. It had mold growing off the leaves it had been there for a bit.
