Re: Advice on equipment replacement I can't speak to the continuously variable pool pumps - while they do have all of the benefits as advertised, they're so expensive here, at least here in the Dallas area, that it just doesn't yet make sense to purchase one versus using 2-speed pumps. In the...

Today I finished putting in 50 ppm of borates into my 30,000 gallon pool: 23 boxes + 16 oz weight Borax and the appropriate amount of offsetting acid (about 5 gallons). Success! Water looks awesome! I followed the instructions as posted in the 'sticky' here, and all went fine. I turned the...

Update: Indeed I disconnected the 4-button spa remote control wire connections at the power center (pulled off the black connector from the PCB). Three days later, all remains fine. No random cleaner motor startups/shutdowns. (And since I have a energy monitoring and control system, I can...

Update so far: I studied this (great) forum for other postings related to Aqualink systems. I found one saying that remote spa link units, if present, after they age over time, can cause problems like what I'm seeing. Indeed I have a remote spa link unit connected. So, later today I will...

I got an answer from a pool professional that I thought I'd pass along: Yes, use of an RS6 all button panel with a system with an RS8 PPD/chip will work fine, you just won't have control capability for the last two (7th and 8th) devices. Best regards, Bill

Does anyone know if a P&S RS6 All Button panel can continue to function fine if connected to a Rev R PCB with a P&S RS8 CPU? I know that I need an RS8 All Button panel, or a One Touch panel, to get access to the last two devices. But if I were to just upgrade my Rev K P&S RS6 PCB with a...

EDIT as of 7/11/2012: The 8th action I tried was to disconnect the spa remote cable connection from the power center's PCB. This action resolved the problem. Conclusion is spa remote (15 years old) is defective and I'll replace it shortly. Next time I get equipment turning on/off randomly...

I recommend looking at a robotic cleaner. From a pool operating cost point of view, I think you're in the 'sweet spot' of those who can get the biggest return on the investment. Here are my thoughts. In my case, last year I consumed about 7000 kWh last year to run my various pool pumps...

My experience with Jandy AquaLink control equipment has been outstanding. I've had an AquaLink RS6 + Power Center + All Button Controller since 1996, without ever a failure. This includes my Jandy Valve Actuators (JVAs). My AquaLink equipment is outside, in a West facing setting, and thus...

Yes, I'm pretty sure on the numbers, as I have a pretty solid energy savings monitoring system ( http://www.welserver.com/WEL0043 ). Some things to consider that could explain the performance increase: I overhauled the pump at the time I changed the motor. All new O-rings (diffuser, seal...

Mark, thank you. I've learned what 'works' on Lo speed. I'm still learning what 'works well' on Lo speed. Best regards, Bill

Why do you run your filter pump on high when your cleaner is running? Does you cleaner not work properly if your filter pump is on low? Is your cleaner a pressure side unit or something else? Many thanks! Best regards, Bill

Mon., Aug. 15th Update: The AquaLink 2-speed motor relay kit (Jandy 6796) arrived last week and yesterday I installed it into my AquaLink (All Button) RS6. Now I better understand why control of my newly installed 2-speed motor using this relay kit is a good idea. I'm pleasantly surprised to...

OK, for those of you wanting some pictures, here are a couple. First, here's what a Sta-Rite Max-E-Glas II pump looks like with the manufacturer supplied 48Y square flange single-speed motor. In this case it's a model P4EA6G pump with an AO Smith USQ1202 motor (total 2.2 HP). This pump was...

Wow! Much appreciated! very helpful! So let's see now - I can further save some money. At low speed, I now know I'm moving 34 GPM. For a 30 KGal pool, that means I need to run the filter pump on low speed at least 882 minutes each day to get a full turnover of water daily. That's 15 hours...

This is much appreciated! Distance from pad to center of pool is approx 50 feet. Pad is approx 1 foot higher than surface of pool water (pool has a deep end with diving board). All pipe sizing is in my signature. Here's an image of the pool equip (before making pump motor change): (The...

I just guessed that my (hi speed) flow was 85 GPM, based on my old single-speed (AO Smith USQ1202) being a 2.2 tHp motor in a Sta-Rite Max-E-Glas II P4EA6G pump. I don't know how to estimate flow rate more exactly. Your comment is helpful - I didn't know flow volume is linearly a function of...

Wed., Aug. 10th Update: The new 2-speed pump continues to run at about 330 W. Assuming 230 VAC, that's 1.4 A. I have the pump set to run for about 20 hours each day - on at 1:30 AM and off at 9:30 PM. I don't have any way of knowing if I'm getting one complete water turnover for my 30 kgal...

I didn't know this. Thanks! Best regards, Bill

Sunday night, Aug. 7th update: Milestone day! It looks like I have successfully replaced a single-speed 48Y frame sized motor on a Sta-Rite Max-E-Glas II pump with the best efficiency 2-speed motor on the market today (which happens to be a 56Y frame size). I first started up the pump on high...

See the posting I've been updating, changing out a 2 THp single speed pump for a high efficiency 2-speed pump on a Sta-Rite Max-E-Glas II pump. There's a fair amount of detail that may be helpful to you. Best regards, Bill

Friday, Aug. 5th update: Today I received the new base from aqua-man.com. Yipee! It perfectly supports and fits a 56Y square flange motor. I've learned today that if you're going to replace a 48Y with a 56Y motor on a Sta-Rite Max-E-Glas II pump, purchase of a new base is fundamentally...

Spectralightuv indeed offers whole pump/motor assemblies, and, motors alone. For 2 THp, it's either the EP-6 (pump/motor assembly) or the EM-6 (motor alone). In either case, it's the same motor. It looks like this company is using the recently available AO Smith E-Plus High Efficiency 2 speed...

August 1st Update: The Sta-Rite Max-E-Glas II pump's base w/ motor pad (C104-78P) is listed by Pentair as a 48Y base. There's another base available (C104-79P) that's listed by Pentair as a 56Y base. It's detailed in the parts list for a Max-E-Glas II as a base only for 3 Hp pumps. I called...

Re: 2 Sp Pumps on Market using AO Smith E-Plus Hi Effic Moto This is very helpful commentary. Much appreciated. I do understand what PF is, and thus you've brought up a good point. I didn't know the AO Smith E-Plus motors use a separate winding for low speed. Perhaps this helps to explain...

Re: 2 Sp Pumps on Market using AO Smith E-Plus Hi Effic Moto Thank you. I agree that it looks like the WhisperFlo WFDS-6 / WFDS-26 may use this pump. If I end up replacing my whole pump (2.2 THp), I'll replace it with a WhisperFlo or an EcoPump EP6. Best regards, Bill

This thread's dialog was very helpful reading. Much appreciated. Best regards, Bill

Re: 2 Sp Pumps on Market using AO Smith E-Plus Hi Effic Moto James, thank you. I will look at the Jandy ePump to see if it's reasonably cost effective versus moving to a 2-speed pump, noting I already have an AqualLink RS controller. Parenthetically, except for the Eco Pump EP-6, I sure...

Re: 2 Sp Pumps on Market using AO Smith E-Plus Hi Effic Moto Yes, thank you, I have. Unfortunately (fortunately) my electric rate is 9¢/kWh, and thus the variable speed units have a pretty long payback period for me. I run my 2.2 hp (total) pump (10 Amp) now for 6 hrs per day to give me one...

Are there any 2 speed pumps on the market these days that use the AO Smith E-Plus High Efficiency motors (B2981 - B2984)? I looked in the California pool pumps data base, but, while I found some listed, it looks like the data base is not completely accurate. For example, the data base shows...
