Backwashing and brown water

[smithp]

Read the pool school article on backwashing. So dense I still have a question. Tried backwashing and brown water (I quess it was sand) blew in from water jet. I do not see a valve to open to make water go to drain pipe. Do I have to attach hose to water jets? HELP. Will try and attach a pic of filter set up. Pic shows pipe on right which goes to ground for draining pool but did not see water come out when backwashing. But only left it on for a few secs since looked like sand into pool.
iPhone not ketting me add photo. Will add when i get back inside

Do you have a multiport or a slider valve?

Great question??? Can you tell me from these pics?
Have also attached pic of plumbing setup.

The position under the handle (opposite of the current setting), should be the backwash setting. That allows water to go through the pipe on the right near the wall. You should see water in the small sight glass on the port leading to that pipe when baskwashing. Once done backwashing you should rinse for about a minute, then put it back on filter (current position). You have a top mounted multiport valve.

Make sure the pump motor is turned off when changing the lever.
I didn't know at 1st!

Will try. Last time I did that I had brown water flowing into pool from water jets.

Have you backwashed w/no problems before? I don't know your plumbing or valve setup, but wondering if you're plumbing is set up incorrectly?

If you have a spider gasket problem it could bypass dirty water back to the pool in backwash. I'd take the top off the multiport and check the gasket. Your local pool store shoud carry a replacement.

I Did the backwash and it happened again. Did it once again and used the rinse setting in between and now there is Bo brown water. Thanks for all the help. Next battle is algae. Got to go read in the pool school.

Right. You have to 'rinse' after 'backwash' each time.
