I've owned a Jandy AquaLink RS for about 8 years, since I first built my swim-spa. In all that time, I never had an issue with my heat pump (AquaCal TT120, a digital thermostat heatpump that supports 2-wire remote triggering). I used the simple 2-wire connection between the Jandy and heater...

My heater is not turning on because the pressure switch is apparently not being triggered (seeing the "FLO" message perpetually). I'm trying to isolate whether it is: (a) bad flow switch (or) (b) pump volume has gone down for some reason Hardware involved: * AquaCal TT120 Heat Pump (internal...

Ugh, boy did I do it... I have the "U.S. Motors" 2HP motor (formerly Emerson 1202 aka EUSQ1202 aka USQ1202) that's often used as a replacement for AO Smith square-flange pumps. After I had rebuilt the pump, I began moving it into the equipment pad, navigating between different pipes. I just...

Hi all, I own three Whisperflo that I purchased as "remanufactured" pumps from a local company that is no longer in business. The pumps have been working just fine, but I have some suspicions that the company may have taken some shortcuts when refurbishing. When I recently went to do a pump...

I've had a Jandy Stealth 2.5 HP pump for about 8 years, which is rarely used (used for spa jets only, no recirculation/etc -- about 10 hours a month usage). Recently, I noticed the output decreased significantly, and there seems to be a little air coming out along with the water from the jets...

Hi All, Thanks to great advice from mas985, I recently replaced a couple pump motors/impellers. One was the recirc pump, that went great, no problems. The second was a pump used for spa jets. It is a Whisperflo WFE-6 on a 2.20 SHP Emerson pump (correctly sized impeller/pump combo). When the...

Hi all, I believe I understand the difference between Full-Rated (and) Up-rated pumps, and I've read the excellent post on them @TFP, however, I've always wondered whether an up-rated pump would be more energy efficient than a full-rated pump, considering the motor in an up-rated pump is smaller...

I've had a problem that has not affected my pool-clarity, so I've essentially let it slide. However, the more I read the forums, the more I'm concerned by the issue and if nothing else, figure I should at least understand why its happening. My DE filter (Hayward ProGrid 24 Series, the DE2420...

I've searched and searched on Google, because this seems like an overly simple question ... But I just can't find any information on where the sacrificial anode is normally located in a pool heat pump. The company that makes my heat-pump is out of business, and while browsing the manual...

Two years ago I installed a fiberglass swim-spa shell. Because I was building it myself, I plumbed everything identical to a pool. It's got a remote equipment pad, Jandy-Managed, DE Filter, 1x 1.75hp recirc pump, 2x 3hp jet pumps. It's about 900 gallons, never covered, in South Florida sun...
