    rejuvenating an old intex 2500 gallon filter pump

    Last year my pump started acting up. If you turned it off sometimes it would not turn on. If you turned it on and off a few times it would turn back on. I checked for obstructions and found none. I assume it is on its way out. Is there anything I can do to help it along? I tried taking it apart and was going to try and give it a a shot of wd40 or silicone spray on the brushes but couldn't find any. Is it a lost cause or is there anything I can do?
    1) The size of your pool in gallons 4440.
    2) The type filter you have is an Intex 2500 gph and it has a re-useable fabric filter
    3) If your pool is an AG (above ground)
    4) Intex 15 by 48 metal frame.
    5) If you know, tell us the size pump 2500gph and the size (flow rate) of your filter.

    It could be the centrifugal switch contact. It's under the back cover.

    Is that the thing that looks like a relay?

    It looks like a "V" with copper strips and has a set of contacts. There's a mechanism under it that actually operates the contacts. It has springs. Make sure it operates and clean the contacts.

    I just took it apart. I couldn't see the V that you were talking about. I googled it and didn't see anything that looked like my pump. It seems to have a fan on the back and beyond that I see the windings of the motor. But I gave the fan a spin and it moved very freely. I hate to use the smaller backup pumps and really want this one to work. I did test it and it hummed.

    That looks like a switchless design. Is there a capacitor on it?

    That's probably your problem. I'd get a new one and see if that solves your problem.

    Any idea where to find them. I can only find ones for ceiling fans and they are not the same size.

    You got lucky there. That's not a common cap. Glad they had one.

    Re: rejuvenating an old intex 2500 gallon filter pump

    Well I was looking at the other thread and they mentioned using a regular can style. At the store the guy looked at me like I had 3 heads. And he knew it was from a pool. He offered me a 15uF and said it shouldn't make a difference. I imagine the cap was for starting the motor given the fact that the white wire just passes through. But it worked and if it blows up hopefully it won't get the pool!
