I bought a used sand filter off Craigslist. I don't know the brand and there are no readable markings. Can anyone give me a clue as to which port is which? (i.e. can you tell by which side the pressure gauge is etc?) I'll be hooking this up to a 3/4 hp pump and 12000 gallon above ground pool. From what I understand the hose from the pool goes to the pump, from pump to intake on filter, and output of filter goes back to pool, and the 3rd port is for flushing/waste.
Any hints etc are greatly appreciated. Also if anyone has any generic instructions for using a sand filter and what to do the first time you run it, flush it etc.
Here are some pics.
