Pump doesn't backwash anymore

[ldragan]

Hi,

I have an above ground pool and while vacuuming some heavy debris from the bottom of the pool the sand filter clogged very quickly. I backwashed three times but the last time no water or very low flow came out. The pressure starts around 10-12 psi and tops at 20 psi while filtering. I can still run on filter at around 15 psi but backwash is at 20 and barely spits water out. Normal pressure while backwashing is below 5 psi.

Looks like the backwash is clogged but I don't know how to clean it.

Welcome to TFP! What type of set-up do you have? Your signature is blank. Maybe post a pic or two of your equipment pad so we can see everything.

Thank you, I'm new to forums, I saw some good answers in this forum so I figured o give it a try.

It is dark already here but I've attached a couple of pics with the pump and filter.

I tried to backwash again and I got a good soaking. I left it on filter for about an hour and refilled the pool so maybe I got lucky and it's back to normal. I will reattach the drain hose and give it another try.

Thank you for your answer.

I've just reattached the hose and it look back to normal. Not sure what happened before.

Glad it cleared. Sounds like some junk got past the pump strainer pot basket and perhaps into either the pump impeller area or filter itself. Either way, good you have water flow again. If you have to vacuum a lot of junk from the bottom again, be sure to place the MPV on WASTE first so that the junk goes straight out onto the lawn. Have a nice weekend.
