    Pump psi seems too low

    We just got a doughboy desert Sierra 24 foot round 52 ". It has a media master sand filter. When it first got started it was running at 10 psi. I then vaccumed pool and emptied the basket on the pump that was full of leaves and since then It is only running at about 5-6 psi. Is that normal?

    Welcome to the forum!

    No, what probably happened is that some of those leaves got stuck in the impeller. Take out the pump basket and there is a hole at the bottom of the basket area. Reach in and see if anything is stuck in there. If you cannot feel anything, you may need to take apart the pump but hopefully you can reach it from the basket area.

    Thank you I will check that. When you open that filter up water just comes rushing out of there. There is no valve that I see to stop the water flow. So it makes it kind of hard to get the lid back on.

    Check the skimmer and returns for a valve. For an AG pool, you must have valves on the suction and returns lines in order to maintain the equipment.

    On my Pool I had to add a Valve on both lines.
    You can use a good quality Duct tape on the Discharge Hose inside the pool in the water.
    Then put something in the skimmer to block the hole. I used a toilet tank flapper thing.
    Leaks some but may give you enough blockage to work quickly.

    There were several leaves stuck inside the impeller of the pump. I got them all out and pump is running at 13-14 on high. Thanks!! When I turn it to low setting its only at about 3 psi. I'm guessing that is normal??

    Yes, pressure will go down quite a bit on low speed.
