Why is my above ground swimming pool pump not working properly?

April 10th, 2011 § 4 comments




The pump seems to work fine, but when we connect the vacuum the suction decreases drastically. It may work for a couple of seconds, but then it stops!! I’m not sure whats happening, but we can’t get the pool clean. The filter is new and the pump is fairly new, not even a year old and it wasn’t even used that long. There is nothing clogging the filter or the hoses. Any help would be great.

    i own a pool company and you need to back wash the filter.let me know what kind you have.de filter powder,a sand filter,or a cartridge filter. let me know before you do any thing because there are certain things that you do to each one

    there is a plug inside of the pool to keep the water in
    when you turn the pump on it pulls the plug back in place, [ had this happen] got some strainers and placed them in the inside hole cured it,
    suction hose goes on the bottom hole

    Most commonly when this happens there is air in the lines or the vacuum hose itself has air in it still and not completely primed. Make sure the vacuum hose is completely filled with water and all the air is out of it. Also make sure you are starting out with a freshly back washed filter. Some vacuum hoses also have a specific end called a swivel cuff that end needs to be the end attached to the vac head as if it is not will allow air into the lines and kill the suction. Make sure you have no leaks anywhere along the system as even a slight leak can be a major inlet for air when attaching the vac head. Make sure your vac plate is seating securely and has no cracks in it. Also if you have a 2 speed motor make sure it is on high and not the low setting. Again you either have air in or getting into the system, or the system is clogged with debris. Hope this helps and also check out my free informational blog for pool owners on my site http://www.swimtodaypoolservice.com as I believe I have a more detail post on this issue.
