Moved from here. Hi, I'm planning on doing the same: glue back disintegrating bands on the filter cartridge. I have two questions: Can I use simple hot glue if my pool also has a spa? The water gets pretty hot, up to ~104 F in the spa. Will hot glue hold up at those temperatures? My worst...

I know about the basic technique of interlocking the booster pump so that it can be energized only if the main pump is also energized. I have that: this is built into my EasyTouch controller. But recently a microswitch failed in my CVA-24 valve actuator, and that could have caused the booster...

A microswitch in my CVA-24 valve actuator developed an intermittent contact issue. So the valve stopped turning, and I had to replace the microswitch. But this happens too often: another microswitch failed on me 2 years ago. At that time, I've replaced both microswitches in both of my CVA-24...

I'm a little confused as to what does exactly "1 ppm free chlorine" mean? I know that "ppm" stands for parts per million, and I also learned that it's always a mass ratio, not volume or moles or anything else. So, 1 ppm = 1 lbs in 1,000,000 lbs. But 1 lbs of what exactly? Of NaOCl or of...

I noticed something today while I was watching the controller. It was cycling the heater almost constantly, on the order of 20 seconds of so. In more detail: I was running the spa, set at 98°, and the temperature (as measured by the EasyTouch8 sensor) was jumping back and forth between 98° and...

How reliable is the diverter seal in a 3-way Never Lube Jandy Valve? Can I use that valve to isolate certain pipes during pressure testing, at say, 15 or 20 psi? I'm interested if it can be used in either direction, that is: 1) If I set the valve to close a certain pipe, can I pressurize that...

Seems like I have an EasyTouch 4 or 8 control panel with an IntelliTouch Indoor Control Panel (p/n 520138). At least I think this is what I have. And it does not work well. Is this supposed to work at all? (I've bought it with the house, and already fired the pool maintenance person who...

Hello, I'm just beginning to learn how to maintain my pool. I have a stupid question about how to use the in-line pentair rainbow 320 chlorine feeder. I've followed the instructions: closed the control valve, then stopped the pump, waited, then restarted the pump, then opened the lid. The...
