Backwash help

[Mike_St]

Hello Community,

I'm trying to do a backwash on my pool system, and have watched several videos on YouTube.
I don't have a valve to turn and pull to open the backwash line (it's somehow connected to the sewer line).
The setup is a bit confusing to me, I'm not sure which valves to open/close to do a backwash (see attached picture).
I can post more pictures if needed.

Thank you, any help is very much appreciated!

Hello Mike and welcome to TFP! So you have a multiport valve (MPV) just before the filter that allows you to change settings. After you vacuum or just over a few days' weeks when the filter pressure increases by 25% it's time to BACKWASH. You always turn off the pump before changing settings. You depress the handle and turn it to BACKWASH and run it that way until the water looks clear coming out of the waste line if you are able to see it. Once you are done backwashing, turn off the pump and change the MPV to RINSE and let that run until the sight glass is clear. Maybe another 20 seconds after that to be safe. Then go back to FILTER (pump off first) and you should be set.

Hope that helps. Don't forget to update your signature with all of your pool and equipment info to include your test kit. Have a good day.

Pump off, turn dial to backwash, turn back on and let it backwash. You can't see all the dirty water, but you do have a sightglass.
Watch that. It should go from clear to dark to clear again. When its clear again, run a bit more.

So just turn the dial on the multiport valve to Backwash?
I don't need to change anything on these two black valves?
Thank you!

Mike,

Nope...

But before you backwash... Make sure you have new DE on hand, and understand how much new DE you will need to add, and how you should do it..

The label on the filter says 6lb of DE. I will put it in the skimmer closest to the pump while running in normal filter mode.

Thanks y'all!

Mike,

I suggest that you put the 6 lbs of DE in an empty 5 gallon bucket.. Then fill the bucket with water.. You be amazed at the amount of water you can still get in the bucket.. Stir it up into a slurry and then slowly pour the slurry into the skimmer.. This works so much better than trying to dump dry DE into the skimmer.

Thanks,

Jim R.

Mike ,

Not sure if it really matters , but I was told to always turn the handle in the same direction every time ie always clockwise or always counterclockwise.
