We just got this house with a pool about two weeks ago. I've learned so much from this forum. But backwashing has got me confused. I've read the web, YouTubed, Googled, etc. but none of those situations seem to fit mine - specifically, where does the dirty water exit? Would you please take a look at my pictures (sorry about phone camera) and give some guidance on how to backwash? I have attached a front (1st pic) and back view (2nd pic). Oh, the pipe going to the ground has water coursing through it when the filter is running - well all three pipes are live when filter is on.
The equipment is a Jacuzzi TM-22 multi-port valve, a Jacuzzi Sand Storm filter, and SWG. Our property is on a septic tank - certainly this system wasn't set up to discharge to septic?[attachment=0:2srl8nb4]Pool_01.jpg[/attachment:2srl8nb4]
