    Pentair CNC Plus 420 Source? - SE PA, Central NJ, or Online

    After 10 years of dealing with DE and my quad 60, I'm ready to move on. Planning on a Clean and Clear Plus 420 (a little larger filter area, a little better flow). I'm looking for a source to purchase, either locally in Southeast PA (I'm northeast of Philly) or Central NJ. I'd also consider...

    Adjusting for SWG - having challenges with TA and CYA

    My SWG (IC40) appears to be done after 4 years (of 12 hrs per day during season). It never quite kept up with demand, so I'm trying to get the replacement to do a better job and longer by making some fundamental changes to the chemistry BEFORE the new one goes in (also decreasing pool run time...

    Cannot keep Chlorine in the pool...and cannot get CYA to increase

    I cannot keep FC in my pool this year. I had a bit of a problem last year, but it is much worse this year. We are adding a gallon of bleach nearly every day to keep up. Let it lapse a few days, and the FC drops to 0 and the pool immediately turns cloudy, can't even see the bottom. ~28K...

    Light Junction Box Grounding / Bonding Confusion

    I have 2 pool lights and 1 spa light in my in ground pool. The conduits run in series from the farthest light back to the pool pad. The conduit to one of the junction boxes was broken, so I removed the Hayward SP0681 junction box and replaced the conduits. No problem there. It is the bonding...

    Subpanel Mounting Options

    I'm installing an EasyTouch subpanel next to my pool equipment. Here in the NE, pool equipment tends to be installed away from the house, so typical subpanel mounting on the house isn't an option. The old subpanel is mounted to a 2x6 that is simply buried in the ground. That won't be...

    Variable speed - or not?

    I have another more generic thread on this topic, but wanted to get some input specifically on the applicability of a VS pump in my pool. As background, I'm replacing all of my pool pad equipment (old, worn out, noisy, leaking, etc.) in my ~25K gunnite pool / spillover spa pool. I will also...

    Advice on equipment replacement

    I recently purchased a home with an older in ground pool. The home is in eastern PA (Doylestown area) and is on well water (with low Ph but no other major issues noted). The pool needs a lot of work, including new tile and plaster. We'll save that discussion for later... The first order of...

    Fittings bottom-out in pump - now what?

    Background: I have an in ground pool and spa system, about 10 years old. The pump, a PacFab Challenger High Head 2.5hp unit, sits 5 or 6 feet above the pool level due to the slope of the backyard. It has always been a little fussy, because everything has to be just right to get it to pull a...

    Upgrading my aqualink

    I have an aqualink system that was installed with the pool about 8 years ago. I'd like to add some capabilities to the system (waterfall, waterfill, landscape lighting, etc.). My current control head has only 5 buttons (pool, spa, and 3 aux), and the power center only has 4 relays. Can I...
