I have a Hayward sand filter that typically operates in my system at about 17 psi. This has suddenly dropped to about 12 psi. The filter is 12 years old. The motor speed seems normal and the return flow to the pool feels normal, so I’m wondering if there could be a problem in the filter where...

I have a 12 year old Hayward Navigator, whose lackluster performance I've been tolerating for too long. It can barely (and rarely) climb out of the deep end, and never reaches some areas of the slopes. I want to replace it with one that is not only able to cover the entire bottom efficiently...

I just did a deep cleaning of my filter using a hose. I believe I have lost a good bit of sand in the 11 seasons of operation without ever adding sand before. I have a Hayward Pro-Series S244T that is supposed to hold 300 lbs of sand. Problem is, I see no need to remove the old sand and add...

Thanks for the clarification. I was presuming that the SWG actually generated Cl gas that is quickly dissolved in the water, so I was going by the chlorine gas guideline per the Taylor test kit instructions. As of today, the TA is down to 90 and the pH back up to 7.5, so I added another dose...

Thanks for the response, Jason. Let me clarify, are you saying I don't necessarily need to adjust the TA to between 70-80 per the borate adding instructions if that's not where it needs to be based on other factors? My SWG instructions say to have the TA between 80-100. The Taylor test kit...

I still need to score 5 more boxes of borax after cleaning out 2 different Walmarts 3 times, and have 8 gallons of MA on hand. First, following the sticky for adding the borax and acid, I need to adjust my TA to between 70-80. It is currently about 90 to 100, and my pH is 7.5. I understand...

Linen, no, the bubbles only are present when the SWG is actively operating, so I don't think I have a suction side leak. eaamon...about collecting the hydrogen, I actually did think about how to capture some to inflate a plastic bag to make a mini-Hindenberg!

OK, that would explain why I could not detect any chlorine odor at the surface as I expected thinking it was chlorine gas. But then is it normal to see hydrogen bubbles? I didn't find any mention of bubbles from a SWG. If this is hydrogen, I can make a mini-Hindenberg by collecting these...

Just got back from traveling over the weekend...can't say I completely followed the electrical discussion about using the AUX circuit at 120v for the SWG. But the concern I had about using the AUX (circuit #3 on Mode 2) was that I'd have to be careful to coordinate the AUX on schedule to never...

I recently replaced my single speed motor with a 2-speed and wired the SWG to produce only on low speed. Previously with the single speed motor, I would see very small bubbles coming out of the returns when the SWG was producing, and always wondered if I am losing chlorine from any bubbles that...

This post caught my eye while searching for an answer on a different issue. I also have the Aqua Rite, and have had similar disparities between what my cell reads and what the pool store test reads. I have a theory maybe someone can confirm or refute. The first sample I took to be tested was...

Hayward technical support gave me that model number as a backfit for my pump. I ordered it from Amazon and had it in 2 days.

One other thought...it's not the "sharp edges" of the sand that traps particles, it's the small spaces between the grains that limits the size of particles that can pass through. If the sand does in fact "wear", that means the grains would get smaller over time, which in turn means the spaces...

I bought a Century SPX1610Z2M, 1.5 Hp. I was pleasantly surprised that it was shorter than my old single speed motor--fatter and heavier, but shorter. I was afraid the replacement would be longer and hit the wall of my shed...the old one was only a couple inches short of it. The only bad...

Thanks for the reassurance Dave!

No need to apologize, Patrick! You couldn't have known...even the company I ordered from didn't know until I asked why it hadn't shipped yet (it was supposed to ship directly from the manufacturer). The manufacturer actually offered me a 3 hp motor at no additional charge, but since I was...

Success! Got the new motor installed, pump seals replaced, timer and chlorine generator properly connected. I can't believe how quiet this pump is on low speed. One thing that surprised me though...the normal filter pressure is around 14 psi, but on low speed it's only 1 psi. Does this sound...

Great! I think that's the last piece of the puzzle and I believe I understand everything I have to do. I've updated my schematic accordingly, and will start on it tomorrow after work. Thanks for all the assistance in walking a mechanical guy through to an electrical understanding!

Jason, to clarify, when I mentioned the "bare copper wire" from the SWG and breaker, I was referring to the third grounding wire inside the Romex wires. As opposed to the exposed bonding wire that is connected to the external lugs on the motor at the same place the pool bonding wire connects...

Just found this in the Aqua-Rite Chlorine Generator manual: "Wire the Aqua Rite to the LOAD SIDE of the filter pump timer. It is very important that the Aqua Rite is powered only when the pump is running." I expect this is to avoid the possibility that the flow sensor or control system fails...

Steve, that helped immensely! I since found a 4th terminal in the motor where the green connects to the frame--not realizing that was a major point of confusion--I was thinking it must have to connect to the 1, 2, or 3/4 terminals. Now, does the green from the motor, the bare copper from the...

I made a schematic of what loose ends I will have after removing the existing on/off switch, and hopefully have successfully linked to it below. For each loose end I'm not sure where to connect, I labeled "a" through "g". I'm hoping this will make it easy for someone to help me connect the...

To add to question 1. above, I remember reading somewhere that, if upgrading a single speed to a 2-speed motor, I'd have to run a fourth wire through the conduit to the new motor. The new motor only has three terminals, so where would the 4th wire go at each end? I haven't been able to find...

Just wanted to let any one know that reads this thread that you can't actually get the motor mentioned above with the built in timer (1.5 HP Full Rate Two Speed Motor W/ Timer - Round Flange (B977T)). I ordered one, but after a week and still not receiving notice of it shipping, I was informed...

I just bought a new 2-speed motor (A.O.Smith Century SP1610Z2MC) to replace my old single speed motor. I also bought a Intermatic P1353ME timer to replace the current manual on/off switch. I already had a Goldline Controls Aqua-Rite Chlorine Generator that is wired to receive power whenever...

Is there any concern for the effect of the presumably lower pH of the water going through the SWG if dissolving the CYA directly in the skimmer? Can it hurt the salt cell?

I anticipate several backwashes while doing the initial spring cleanup, but I need to get the CYA level up in the meantime to help with the clean up--it's near zero.

I switched to a salt chlorine generator system a couple years ago, but my old chlorinator is still plumbed in. Can I put granular CYA into the chlorinator as a means to dissolve it, perhaps more quickly than the sock in the skimmer method? Otherwise, I'm thinking of making a PVC rig to screw...

Mine was seized as well when I first tried to start it. I tapped the side of the motor at each end (where the motor bearings are) a few times to try to job the bearings loose. If yours was like mine, a small seal leak last year probably got into the bearings. I was able to get the motor...

I'm usually in the mode of needing to increase CH and CYA just from normal water loss, so all the more reason to not waste water.
