    Any idea what this object is on the bottom?

    We resurfaced our pool a year ago. This past week we felt something slightly sticking up on the bottom. We never noticed this before. I brushed it without much effect on it. I also briefly poked at it with a knife. it didn't feel metallic. Would this be something that fell in and stuck...

    Spa pump advice, motor is out

    We have an in-ground pool with spa that cascades into the pool. There is a main pool/spa pump and then a booster pump to provide bubbles for the spa. The spa booster pump motor just went out: it throws the breaker within a few seconds of powering on, and the motor had an overheated smell. The...

    Bulkhead for 25 year old Hayword filter

    I have a 25+ year old Hayword DE-6000 filter that is leaking around the bulk heads. When I look for a replacement part, it is marked as no longer manufactured. Are there equivalent bulkhead parts that will work with the DE-6000? After 25 years, should I just replace the filter? It works fine...

    Help debugging spa pump

    I have an inground pool with spa that cascades into the pool. There is a shared main pump, and a second pump for the spa jets. The spa jet pump does not keep its prime any longer. We turn on the spa pump and do not feel any pressure. If I briefly apply some back pressure to one of the spa...

    Quick fix to Hayward Filter leak?

    I took my Hayward DE-6000 apart for cleaning, reassembled, and now have a small drip where the top PVC enters the filter from the multipart valve. This happened last the pool guy cleaned it, and I thought he fixed it, although he may have done a quick kludge. I would also like to do a quick...

    Upgrading a CP-3600

    I recently upgraded to a variable speed pump, and need to upgrade my Pentair CP-3600 control system. It looks like I can go with a Compool/EasyTouch upgrade, which is reasonable cost and I can do it myself: exchange the left side of the outdoor panel and replace the indoor control unit. One...

    How to test SWG before replacing cell

    My Ecomatic ESC 36 is not producing as much chlorine this season. It has run fine for the 7 years I lived here, and I replaced the cell 3-4 years ago. Since the unit is at least 7 years old, I would like to verify the controller is still good before I shell out money for a replacement cell...

    DIagnose Booster Pump losing prime

    The booster pump for our spa loses prime. Over the past few years, when we used the spa once every couple weeks (sometime longer) it would catch and run fine. If we hadn't used the spa for many weeks, I would have to re-fill the pump basket once and it would run fine. The last few times, I...

    Another Pump Replacement question

    My main Hayword single speed pump motor (maybe 10-20 years old) is screaming, and I am costing out the repair. I am wondering about the trade-offs between replacing the motor or the whole pump. Stats: - Pool is 15 to 20 years old, in ground, gunnite, ~ 12000 gals. - DE filter, probably...

    How to "neutralize the acid" ?

    We have an IG gunite ~ 12k gal pool. Resurfaced last year, had some splotching and calcium build up, so we just had it acid washed. We are refilling the pool now. The pool person set to add 7 gal of muriatic acid, let it sit for 24 hours, neutralize the acid, and then start the equipment and...
