I'm going to install an automated heater bypass, so I need a valve and an actuator. It was easy to find Jandy part number 4717 (3-port 2/2.5-inch Neverlube valve), but there are three part numbers for Pentair actuators, and I haven't found any online documentation to help me choose. I'll call...

As the first step in this season's pool project -- saving money on electricity by reducing head loss in my plumbing -- I'm plotting curves on pump charts. My 3HP IntelliPro VSF pump reports to the EasyTouch its speed, power consumption, and flow rate. But the imprecise flow gauge in my system...

In July of 2022 I found a great deal on Sweepease brushes, so I bought two. I put one on a pole that's stored on top of a deck box, and i stashed the other one away inside the box. I brush very infrequently, maybe once every couple months. But two years later, here's the one that was inside the...

What is the white residue left in the test vial after the salinity test, and more importantly, what dissolves it? It doesn't seem to be soluble in water or alcohol, and I'm not sure that my current mechanical cleaning method is removing all of it.

The wiring instructions and diagram in Pentair's Intellichlor installation manual seem to be all kinds of wrong, so I'm ignoring them. Please confirm that this plan is correct: Existing wiring that I am not changing: 230V Intellipro pump powered from the LINE side of the EasyTouch pump relay...

This is ridiculous. I'm trying to buy a handful of 2" Sch40 sweep 90s and I just can't find them. Tried two HDs, one Lowe's, and an Ace Hardware. Nothing there but regular elbow 90s and DWV fittings. Tried the plumbing-supply store I've used in the past -- they're out of business. Tried...

I've been using a Hasa Liquid Feeder to meter liquid chorine into my pool. Works great, no issues. But now its tank is cracked. And I see from other posts that this is a known defect, and that Hasa is providing the excellent customer service that they're known for and replacing tanks free of...

I'm trying to prevent my heater from turning on when my Spa schedule runs. Schedules on the EasyTouch are as follows: Pool mode (very low RPM) 21 hours/day, from 8pm until 5pm. Spillway mode twice a day during that time, for 20 minutes to freshen the spa water. Spa mode right after one of the...

If you worry about tugging on your robot's expensive cable to lift it to the surface, or if you'd just like to pull it out of the water without having to kneel or squat on the deck, this 32-inch-long aluminum hook makes it easy to snag S200-style handles. It's also great for lifting skimmer...

Target ranges in the Windows app are different from those in the Android app. Which is correct? For my plaster chlorine pool: Target range (plaster, chlorine) Android Windows TA 50-90 70-90 CYA 30-60 30-50 pH 7.2-8.0 7.2-7.8 CH 250-650 250-350 For a plaster SWCG pool: Target...

My phone's timezone is set correctly, I've entered my ZIP code in the mobile PoolMath app, and my timezone is set correctly here at https://www.troublefreepool.com/account/preferences. Timestamps in the PoolMath logs stored on my phone are correct. But when I look at the PoolMath logs linked...

So this is weird... After around 30 minutes in the pool today, Mrs. DrewLG noticed that tiny white bubbles had formed in her toenail polish. She regularly gets pedicures and regularly spends time in the pool, but had never seen this effect before. Photo below. Her polish was relatively new...

I recently finished a SLAM and now I'm trying to lower TA. I measured pH at 7.8 using the phenol red comparator test, added muriatic acid, and after a couple hours measured pH at 7.2. One day later, the pH is back at 7.8. I ran the spa for a couple hours during that time, but there was no...

I've been using a HASA liquid chlorine feeder for a few weeks. Something is precipitating out of the liquid in the tank and settling at the bottom -- there's already a half-inch layer of it. The HASA patent says that this is NaCl, but I can't test it because I don't want to disturb the...

So this pool came with the house. As you can see from the photo of the steps, the surface finish is inconsistent -- top step is grey with streaky brown staining, next step is less so, bottom step even less. The closeup photo shows the bottom of the pool: irregularly light- and darker-blue...

Hi, finally registered after lurking forever. I have what I think is a pretty standard setup, with equipment comfortably oversized for my pool. Details are in my signature. I've gotten a lot of useful info here. Hope I can contribute something back.
