    Mystery Pipes (and 2" or 1.5")

    No spa, nor any signs of one. Being in FL at seal level, someone once guessed that one of the pipes could be used for a pump to remove the ground water under the pool; in the event that the pool needed to be completely drained, this would keep the pool from popping out of the ground. However...

    Mystery Pipes (and 2" or 1.5")

    Hi, I am moving my pool pump and filter about 15 feet, so I am starting to plan for extending my plumbing. While doing so, I came up with a couple mystery pipes: One (marked "A" in the picture) is 1.5" and always seems to have a little water in it, usually above ground/pool level. Today, the...

    Spa pH always high

    Each evening, I measure (and local pool store confirms) a spa pH of about 8.0, so I add the recommended dosage of pH Down--lately, out of frustration, I've been doubling the dose; next day, same problem. I've also tried double-doses of 31.45% muriatic acid--adding about 8 tablespoons (4 oz) in...

    Pentair Intelliflo VF Clock Backup Battery?

    My Intelliflo's clock resets to midnight if the power is disabled for more than a few seconds. Pentair customer service confirmed it should retain the time for 96 hours, and stated that if it wasn't, something was wrong with "the capacitor that holds the time." The only thing that could fix...

    Thank you, Mark. I'll experiment with shorter run times!

    Lowest RPM/GPM for Intelliflo VS VF (11012)

    I have a question about programming my VF pump. I have a 13,000 gallon pool, and I programmed the pump to run 24/7 and to turn the pool over 1x/day. Doing the math, (13,000/1440 minutes in a day), I would expect the pump to run at about 9 GPM. However, on a clean filter (2 PSI) it runs at 1035...
