Something I wish I'd known earlier, before I broke a few fans in awkward places (like inside laptop computers): Fan bearings are designed for a particular range of speeds, and they can fail if they're run above that range. So if you clean fans with compressed air, turn off the fan and hold the...

Nothing to worry about, that's just a vent to let trapped air escape.

Anything up to 28 ppm (the SLAM level for a CYA of 70) is safe for your equipment and for people.

Taylor K-1106. Link is in my signature.

And it's easy to check to see whether you used enough powder: After performing the FC and CC tests, add some more pool water to the clear solution in the test tube. If it turns pink, there was more than enough powder for the sample. (Of course, this only works if your sample turned pink when...

If you switch the Pool circuit from GPM to RPM as well, the water feature will run at the right speed.

Normally when multiple features with different pump speeds are simultaneously enabled, the EasyTouch compares the speeds and chooses the highest one. You know this already; it's why your pump speed increases to 24GPM when both Pool and Cleaner are enabled, and it's why you're concerned about...

6 pounds of dichlor in your 30,000 gallon pool would raise FC by only 13ppm. Is it possible that you performed the FC test with a 25ml sample but counted each drop as 0.5ppm instead of 0.2ppm?

Yes, the key is that you use WAY less power by running at lower RPMs for more time. So, for example, in my system I get these numbers: 1650 RPM: 24 gallons per minute, 230 watts 2400 RPM: 48 gallons per minute, 740 watts So if I want to pump 4800 gallons through my filter -- you wouldn't...

Ex-Nester/Googler here. Let go.

First thing I'd try is moving the start of the schedule to some other time. If the pump then primes at the new time, you'll know it's the schedule that's causing it. After that, I don't know. To me, it sounds like your pump is priming because it thinks it's being told to stop and then...

Do you have a programmed schedule that ends at 23:59 or 00:00, and one that starts at 00:00?

With your back to the sun, it's kinda hard to do it any other way...

You bought the Standard Sampler, so you have a 50ppm CYA sample that you can use to calibrate your eye. Wait for a sunny day, then perform the CYA test using that Standard instead of pool water: Fill the CYA test bottle to the 7.5ml line with liquid from the CYA Standard. Add CYA reagent to...

Thanks, guys. Don't know why I didn't think to look in the wiki...

Maybe not a direction you want to go, but you could also consider switching to an electric robot. Depending on your cleaning schedule and cost of electricity, a robot could more than pay for itself. And that's without counting what you could make from the sale of your good used booster pump...

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...

This kit: TF Salt Bundle

Or get the OTHER Taylor comparator block -- the 9781, from the Taylor K-1000 kit. That one works with R-0014, and you can buy it from tftestkits.net along with your reagent refills.

Masking tape, carefully applied, will give you both a depth indication during assembly -- so you know when you've pushed the pipe far enough into the fitting -- and a clean mask line so the only visible primer/cement will be in a thin ring next to the fitting.

Pro tip: Adhesive tape -- clear packing tape, duct tape, etc -- will cleanly lift all those glass fibers off of and out of your skin.

Thanks, guys. @JoyfulNoise I do not yet have an external heater bypass, but I think I'm going to install one. My EasyTouch seems able to operate a diverter valve when the heater turns on, but I guess I should test and confirm that before I spend the money on a valve and actuator.

Hairnets in your skimmer basket will keep small debris out of your pump and filter. I use these; they work great for regular skimming action and I expect that they'll work fine with your vacuum, too: https://www.amazon.com/dp/B07PSFDT6W They only cost 10 cents each, so they're disposable.

If the flow is good right after you clean the filter, but then gets worse over a few days, I'd suspect that algae is clogging the filter. Especially because your filter is the small size that Florida builders apparently prefer. Have you performed an Overnight Chlorine Loss Test to determine...

Yes, agreed. For me it's around $30/month to run at 1200 RPM, which is why I haven't done anything about it until now. But I installed an SWG last year, and to get enough flow through it I have to run the pump at 1800 RPM. The pump-reported power consumption at that speed costs around...

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...

Installed new filter cartridges. Was hoping they'd let me run my pump more slowly, but they flow only a couple percent better than the old cartridges, and the difference is likely only because the old carts are dirty. Sigh. Might be time to install a heater bypass. But maybe removing my...
