Thread: Possible New Pump

    Possible New Pump

    So I have a Pentair WhisperFlo filter and I have air leaking into the strainer basket and its starting to be a lot louder. So I am thinking of replacing the pump. The pump is probably around 10 years old, but can't confirm. Would it be in my best interest to replace the whole pump?

    Re: Possible New Pump

    Air leaking in might not be related to the pump itself, could be anywhere on the suction side. Have you checked all the seals?
    And getting louder points to bearings (which could just use a replacement of the motor with a 2-speed version).

    Easiest and cheapest to just replace the motor and shaft seal, but if there is a problem with the pump itself, then you could go with a new pump.

    Also, is there any way I can figure out how old this pump is? Also, how do I know if mine is 2 speed?

    The motor plate will tell you if the motor is 2-speed. But if you do not have a switch to change it, then I doubt it is.

    No way to know the age of the pump itself really, but there is nothing to really go bad with them either.

    Also I have confirmed it is a single speed pump. Would I save a good amount of electricity if I want to a 2 speed pump?

    Easy to save 50% of the electrical cost by running on low.

    Re: Possible New Pump

    So it may be beneficial for me to get a new filter to save on all the electricity costs. Is the WhisperFlo still a good filter? What are my options?

    Re: Possible New Pump

    The Whisperflo is a pump not a filter. You can get the savings by putting a new 2-speed motor on your existing pump. Or buying an all new pump ... but I can not recommend a size because you have not done this:
