Will backflushing my DE pool filter into a sanitary sewer line clean-out cause problems (clogging ?). I wouldn't do this into a septic tank, but how about city sewer ? Looking for a way to get rid of the dirty DE material. Options are:
1 - Take the filter apart and hose off in the driveway, or yard somewhere (messy) 2 - Backwash into a large hose and drain into the yard somewhere (messy) 3 - Backwash into a garbage can w/ a hole in the bottom, lined with a large trash bag, let the junk settle, drain the water through a small hole (still messy) 4 - Install a separation tank - (tried this ... kept having to replace the cloth bags as they blew out ...). 5 - Backwash into a large hose that empties into a sanitary sewer cleanout.Ideas ?
