    Reducing Suction on Vacuum head.

    Since installing new pump.Suction is to much when cleaning.Just suck's head to the floor and hard to pull & push.Low speed is not enough so is there any other suggestions to cut the suction back?I did turn my skimmer valve back a little and tried.Not much help.

    Are you closing any suction valves that the vacuum is not connected to?

    Do you have a shut off valve on the pressure side of the pump? Throttle flow down a bit using that valve.

    Re: Reducing Suction on Vacuum head.

    I'm at a loss.

    My only thought would be an older vacuum head with bristles worn down? (Mine is). my cheap vacuum head for a vinyl lined pool has a rubber gasket like thing on the outside of the triangle head and sometimes that rubber part slips off a little (despite my efforts of gluing it back in place) onto the bristles which causes the vacuum head to have more suction to the floor that the bristles normally prevent.

    Head is fine.Not the problem.Just to much suction.I always take my hand and check for suction before vacuuming.Today it got my hand and I didn't think I was going to come loose.Was in the water &by myself.Scary!!!

    Re: Reducing Suction on Vacuum head.

    How do you clean the pump basket without a valve to shut off the pool flow to the pump?

    Yes & close the multi-valve.I closed the skimmer valve a little &couldn't tell much difference.Didn't want to starve the pump.

    If your skimmer valve is the only way to restrict flow keep a close eye on your pressure gauge.....don't let it drop too low. What was your psi before you started restricting the flow?

    I didn't check.I was in pool today and reached over and closed just a little.I need to add a valve on return side.

    There is a vacuum head with adjustable bypass. I'll try to find the post about it.

    pump basket air - should there be any?
