Thread: No suction to skimmer

  1. Back To Top    #1

    No suction to skimmer

    I have a 10k gallon pool with DE filter and in ground pop ups. Pressure is fine and pop ups are working but nothing is getting sucked into the skimmer at the moment, there is debris over the entire surface of the pool. Is something blocked?

    Welcome to tfp, tantontowers

    If you popups are working and are fed by the same pump that is hooked up to the skimmer, then the water must be coming from somewhere. Do you have floor drains? If you do is there a valve at the equipment pad that allows you to choose floor drains verses skimmer? Posting a pic of your equipment pad may help. Also, it might help if you could post a picture looking down into your skimmer basket area (with the basket removed).

    Welcome to TFP!!!

    One more question, do you have a weir on your skimmer?
    Although it does sound more like your suction is coming from the floor instead of the skimmer.

    Yes and the weir won't stay in place. Also the leveler isn't working, I have had to turn the water off to stop it overflowing. Here are some pics:

    Re: No suction to skimmer

    The plastic pins on your weir have worn away, so you need to buy a new one (comes with the piece that is screwed into the skimmer).

    Is the flap on the bottom of the float diverter (spaceship) in the skimmer open? If not then that forces the suction to be mostly from the floor.

    Re: No suction to skimmer

    No, I think I closed it. So it should be fully open?

    Re: No suction to skimmer

    Depends how much flow you want through the skimmer. I would mostly open it.

    Re: No suction to skimmer

    Opened the diverter and put new weir in. Ran pump overnight. Still no suction. Debris all over the surface still. Any other ideas?

    Re: No suction to skimmer

    when the pump is on, without the diverter in there, is there suction coming from the skimmer line? stick your hand down there and feel for suction

    Re: No suction to skimmer

    Nope. No suction. Does that imply a blockage somewhere?

    Re: No suction to skimmer

    Is water coming out of the return jets?
    Any valves by the pump?

    Re: No suction to skimmer

    yeah like jblizzle says, are there any valves near the pump? if not, yes your skimmer line could be clogged... do you have alot of leaves? if it's clogged theres a few things we can try

    Re: No suction to skimmer

    By return jets do you mean pop ups? Water is coming out of them yes. No leaves really as I live in Arizona.

    Re: No suction to skimmer

    There is an inlet valve. I have switched to that setting and let the pump run but it made no difference.

    Re: No suction to skimmer

    we need to see some pictures... there would still be pop up returns if the skimmer was clogged more than likely because water would be getting sucked from the main drain. does the pump have full prime? does it sound different like it's cavitating? Doesn't sound like a clogged impeller but that's worth a check, until you send us a pic or two of your setup
