My pump is working well with great pressure. I have brushed the sides down completely and now need to vacuum. The problem is when I hook up my vacuum (both the manual & the automatic) I lose pressure after 5 minutes of vacuuming, and have to shut it down and restart to regain pressure. I have tried backwashing, but that doesn't solve the problem.

The water is clear, but it needs to be vacuumed desparately.
