High pressure, low flow

[pooley1]

Flow into pool was lower than usual so I backwashed to clean sand filter. The unit is giving me a low flow warning when back washing. When I switch back to filter, flow into the pool is still not as strong as normal. Any suggestions?

Thanks

Any bubbles in the pump basket?

I checked it again. I guess the output into the pool feels normal. But when backwashing the flow out of the waste line was flowing fast, at first like normal, then would slow and I would get the low flow warning. There aren't any bubbles in pump basket. Thanks

Low flow warnings while backwashing are normal. The water is going out the backwash port instead of past the flow sensor on the way to the pool.
