    Pump Failure Survey

    This may be a futile exercise, but I am attempting to get to the bottom of why many PBs and techs have such a poor opinion about Hayward pumps. While, I could go through all of the old posts to collect data, I am hoping to get enough responses to this post in order to draw at least some conclusions. So if you have ever had a pump failure of any kind and from any manufacture (not just Hayward), please answer the following questions:

    1) Pump make and model.
    2) Approximate age of pump at failure
    3) Reason for pump failure. (e.g. motor, leak, housing crack, etc)
    4) Plumbing size (e.g. 1.5", 2", 2.5")
    5) Sheltered or exposed installation

    For those "In The Industry" and have collected actual data, please note any and all pumps that you have come across in your line of work but please stick to the facts above. Anecdotal evidence is interesting but it is very difficult to quantify in any meaningful way.

    Thanks in advance to all who participate.

    Re: Pump Failure Survey

    1) Pump make and model.

    Pentair Whisperflow 1.5hp

    2) Approximate age of pump at failure

    Unknown - pool was built in 1987. We bought the house in 2007. Pump motor failed 4/2011

    3) Reason for pump failure. (e.g. motor, leak, housing crack, etc)

    Motor failed - replaced - pump still going strong

    4) Plumbing size (e.g. 1.5", 2", 2.5")

    1.5"

    5) Sheltered or exposed installation

    Partially sheltered from sunlight by large bush, but no structure over pump, so it's exposed to the elements

    Re: Pump Failure Survey

    1) Pump make and model. Pentair Dynamo, 1½hp
    2) Approximate age of pump at failure. 1 month
    3) Reason for pump failure (e.g. motor, leak, housing crack, etc). Bad Capacitor
    4) Plumbing size (e.g. 1.5", 2", 2.5"). 1½" Rigid
    5) Sheltered or exposed installation. Exposed

    This was a case of infant mortality. The entire pump was replaced under warranty. Two years later, no issues.

    Re: Pump Failure Survey

    1 - Hayward Super 2, 1 hp (1.5 thp)
    2 - 6 years
    3 - wet end housing cracked, slow leak that ruined the motor
    4 - 2" rigid
    5 - exposed

    I wouldn't call this a premature failure, and I think it was due to a sloppy installation. I think too much T-tape was used and it was screwed in too tight, which cracked the plastic.

    Probably not helpful but wanted to show my support. Replacement motor had 5 years when retired.

    Thanks to everyone's support! Any and all data is welcomed so keep it coming. With 27000 members, hopefully there are many more that have replaced their pump at one point.

    Just wanted to add that the replacement pump, another Dynamo, this time a 2 speed .75/1.0 HP is showing signs of rust in the same area after 2 years in the elements. It is starting at the mounting bracket, just like last time. I elevated the pump 1/2" off the platform with rubber washers but it doesn't appear to have helped. This one is also noisy so I have a replacement motor I will install soon. Thinking about coating the mounting brackets with that spray on rubber stuff before I install it.
