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...

I bought the motor directly from the distributor (Gorman) they'd be no help, unfortunately. As a matter of fact, buying from any retailer down here in South Florida, I can't imagine any of them having an answer for this one. I am friends with a few shops locally and none of them had any idea...

Thank you Dave, Wow, the right search term makes a lot of difference! I've been able to find a couple more helpful pages on the first page of Google using your terminology ("Dual Voltage"): http://www.usmotors.com/TechDocs/Connec ... grams.aspx This is an awesome post that might be good for...

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 Mark, Ahh, excellent point on the impellers. Very helpful, thanks so much! I had come to a similar conclusion, but not trusting the intellect of the rebuilder (seeing two different impellers) wondered if it might be the 1.5 and 2.0 (full rated) rather than 1.0 and 1.5. If you think it...

Re: Identifying Impeller by MM? Exactly. That was the point. I have two 2 HP motors .. I have a backup 3 HP motor that I will use if one of them goes. I intend to use it with the 2 HP impeller to yield the same results albeit only slightly less efficient use of electricity (based on...

Re: Identifying Impeller by MM? @linen - thanks for the tip! Unfortunately the outside dimension isn't helping, both the 7/32" and 9/32" (which I'm guessing to be 1.5 and 2.0 HP) are about 0.5" exterior width. The vane width is the big difference. @jblizzle - I thought the same thing would...

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...

Zea & Dave, Thank you for the great information! Fortunately I work from home so I was able to follow-up on your suggestions. The waterline is at the top of the skimmer. It's run good in the past when it's much lower, so I'll move on to the next item. The pump basket is very clean, but to be...

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...

@JamesW- Thank you for the reply, I think you're on to something. First, yes, it's a WFE-6, sorry for the type-o. Next, on the diffuser. The set-screws did get installed tightly, however, there was no O-ring on the diffuser for either pump, not on the spa-jet pump that is making the noise...

Thank you for the reply. I tried recording it before posting, but it really didn't sound much different than a normal pump. The volume/unusual noise did not come through in the recording. The vibration is a great suggestion, I should have mentioned that it was the first thing I eliminated...

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...

Thanks again Mark! I wish I could better understand pump head to be able to grasp what you mean, but I think I have some fundamental misunderstanding of it. For example, I keep thinking of head as the amount of effort a pump must make to get the water to its destination. And based on that, I...
