We just recently installed a new Hayward 22-in filter and pump assembly. After the install everything seems to work but the backwash flow is very minimal and wow backwash or waste water flows out the return nozzles

Welcome to TFP.
Are you sure you have the correct pipe connections to your MPV?
Are you sure you have the correct MPV for your filter?
What model number filter and MPV do you have?

The pool is a 20,000 gallon For some reason the back wash is Hello water flow period and during the waist flush the water comes out the return nozzles in the pool period. I'm going to deep wash the filter but I'm afraid they might be something stuck in the valve assembly please tell me what you think
If water is returned to the pool during the backwash cycle then you have issues with the multiport valve

I try to deep clean on the filter to remove any obstructions but it was pretty clean. I'm afraid Maybe the valve assembly has something stuck in it. Can anybody help?
Yes I also think it's got to be the multi port. I guess I'll get a hold of Hayward since it's brand new has anybody ever heard of this occurrence before?

Yes I suspect that the spider gasket is bad or missing? Or could it be plumbed wrong?

It does indeed look as if you have it plumbed backwards - can you confirm which sand filter & MPV you have?
I am checking on the possibility of that it is a Hayward 22-in MPV came with the filter
The thing is it seems to be operating correctly while on filter and waste and on rinse it just seemed a lower pressure on backwash. Could it be Hayward blows less than jacuzzi??
Oh heck, I bet this is hooked up backwards. It's been running for a couple of days on filter do you think I've done any damage?

Hopefully not- change it around & see how it goes. Are there no marks/arrows on the mpv?
Are you getting sand in the pool?

Well sirs, you are absolutely right it was plumbed incorrectly. Dang I feel like a dummy oh well. After correcting it got a little Sandy but looks like everything's working correctly. With the exception that the top of the multiport valve continually leaks a little water coming up from The Notches. Did I mess up a gasket inside or is this something that will wash out over time?? Again thank you for helping me figure out where I made my mistake this is a wonderful website
We had a little sand in the pool over the last day and then after I reconnected it and backlashed and rinsed there was a little more but it seemed to have stopped any sand flow. But I am still curious why the bear have low valve has water coming out of the top maybe it's got sand in it?
There is a small engraved p u m p on the very port and a return I don't know how I missed it
Well, I do know how I missed it the piping arrangement from the jacuzzi brand filter lined up perfectly and it was just laziness for me not to look any closer when I put the Hayward in
