    Need new 2hp pump

    Currently have Pentair single speed that's 7 yrs old and needs to be replaced. Recommend same WFE 28 or is there a better option for pool/spa IG pool?

    Re: Need new 2hp pump

    If you are happy with the feel of the spa jets with your current pump, I recommend switching to a WFDS-28 dual speed. You can use high speed for the spa, with the same jet activity you have now, and low speed for pool circulation and filtering for a substantial savings in electrical costs.

    Of, if your cost for electricity is $0.20 or higher, you might want to look at getting an IntelliFlo.

    Re: Need new 2hp pump

    What is wrong with the pump? You know you could just replace the motor right?

    2 speed would likely pay for itself pretty quickly.

    Re: Need new 2hp pump

    Pump started making noise so was going to just replace bearings. Started disassembly and bolts corroded and one of 4 long bolts snapped. Could not get front screw off impeller looks like started to disintegrate, and thickest Phillips head would not grip. Shifted all my Saturday morning plans and have spent my wknd learning more than I need to on pumps. Info overload. Was happy to find FTP and can't wait to start bbb. I have spent thousands of dollars at two pool shops and I'm just guessing the stuff they kept having me dump in my pool had something to do with eating away at my equip. Whatever they recommended was always to get to point of recommending the next thing they could sell. Just purchased TF100. About ready to order new pump do i need schedule 80 pvc or other install parts to diy? there's a check valve between the pump n filter now. Thx. Ed

    You should be able to get all the fittings you need at the hardware store. Don't think schedule 80 is really needed. Although I liked using the union fittings specific to my pump.

    Are you able to use same pool pump for spa or do you need to have a 2nd pump?

    Is this a question trying to help Edcialk or are you looking for information for yourself? There is nothing in this thread that suggests that this is a 2nd pump

    Re: Need new 2hp pump

    I am always looking to help others and also learn at same time. I am not an expert by any means in pool industry just trying to learn myself, although I was quoted a 2nd pump for a spa and was curious as to know if it it is common for 1 pump to handle both for a smaller size pool.

    Re: Need new 2hp pump

    Pool/spa combos can be plumbed in many ways. My previous house had a single large pump sized to run the spa. I have since learned how inefficient it is to force all that water flow through the filter for the spa and how much electricity was wasted when I did not need the high flow rate.

    "Best" setup is likely a small 2-speed pump used for circulation, heating, filtration and a second pump on a dedicated plumbing run to the spa to only run the jets when needed. But, if that separate plumbing run was not installed, then this setup is clearly not easy to switch to.

    Re: Need new 2hp pump

    2nd pump-That's good to know. I have a inline chlorinator that I currently use and after a period of time in spa, chlorine would be noticeable/unpleasant. Makes sense to use a smaller pump for circulation...will keep in mind for my next pool project. I have a Polaris 380 that has a small booster pump.

    Re: Need new 2hp pump

    So you are using pucks for your chlorine source? Any idea of your stabilizer level since that will build up with the use of trichlor?

    Re: Need new 2hp pump

    Placed the order for my new pump. No one local had one in stock and my noisy whisperflo doesn't sound like it will last much longer. Watched a couple install videos some use grey and some use blue PVC cement. Upside for gray is drying time but any downside? Recommendation for NJ climate?

    Re: Need new 2hp pump

    As long as you use primer and PVC cement (or possibly multi-purpose if you are using any CPVC), any should be fine. I have never seen grey ... usually clear or blue.

    Absolutely not. Although you can keep it plumbed in to use the pucks if your CYA is acceptable while you go on vacation or something.

    When you are home, most of us are adding liquid chlorine on a near daily basis.

    Typically how much chlorine do you use and is there a brand you like &/or cheapest place to get it?

    Probably not worth salvaging in case, but for the broken long bolts, most people just buy threaded rod, a couple of nuts, and cut the rod to needed length for re-assembling the motor. I do bearing replacements for my motors and always seem to break one of the long through bolts taking the motor apart. It seems like most people don't have the time to tinker these days and most folks just go buy a new motor or a pump and motor assembly. The newer 2 speed units will save you a couple of bucks a month on electric.
