  1. I’m trying to remove the impeller from a Hayward Ecostar pump. However the plastic motor fan is exposed there and I can’t seem to stop it from spinning and the impeller doesn’t want to budge. Any suggestions on this type of pump impeller removal?

  2. I’m having trouble with the plastic bolt on my Emerson pump. If i break it off do you carry replacement parts?

    1. So my impeller is a 310-4000 and I cannot remove it. The hex fitting in the center has rounded off. Is the impeller itself threaded onto the motor shaft and if so what direction should it be rotated to remove it? I am able to get a strap wrench around it.

    2. Hello – though the Emerson name is on the pump sticker, they only manufacturer the motor. To help you figure out the best way to remove the impeller we will need to identify the pump. When you look on the pump housing side of the pump, do you see any stickers that say “Pump Model #” or “Model No.”?

  3. I have a FlowClear pump my impeller broke. Told me they don’t sell the part had to get new pump. Stay away from Flowclear

  4. Replaced the impeller but struggling to put it back together. just doesnt seem to want to slide in so i can tighten the bolts

    1. Is the impeller not screwing onto the motor shaft or the shaft seal not sliding onto the shaft of the impeller? if it the latter, you may have a piece of the old shaft seal stuck on the impeller stem.

  5. Hi,

    First time pool owner and I have no suction. I have traced it to the impeller but it looks like I may need to take the pump apart? Just wondering how big of a job this is and if there is any concern getting it to go back.


    1. If you are handy, you should be able to complete the job. If after you watch the video and read the guide above you doubt yourself, I’d either get a more technically savvy helper or hire a service company.
