@look30 - For what it's worth, as I said in my post above, cleaning the pump motor seemed to do the trick for me. No way to know whether yours is having the same problem, but if you're at all handy, it's really not a bad job. Just a few screws to get the motor unit out, then pop the waterproof...

@JoyfulNoise - Tagging you because you seem to have knowledge of electric motors and stuff. Apologies for the delay in posting. Been crazy-busy, but finally had some time to poke at the robot vac. I took the whole thing apart and opened the motor case. It wasn't wet, but there was some water...

Boy is this a roller coaster... I verified on my wattage tracker that it actually ran the full two hours yesterday, which is what I had it programmed for. Cleaned it out this morning, put it back in and.... Now it's failing the startup checks. Moves about 10" in one direction and stops... So...

Thanks everyone! Boy do I feel dumb... Took it apart today and found a piece of plastic on the impeller. I could still turn the impeller by hand, but I removed the plastic and decided to try it again before taking it apart further. Wouldn't you know...it worked... I am interested to see if...

Thanks, @JoyfulNoise. Any thoughts on the solar skimmer?

Thanks for the feedback. Going to open it up today and see what I can find. @Jimrahbe - I don't have a swivel cord. I'm familiar with the startup process you described, and my vac is getting passed that (it hasn't stopped before or during the startup yet) and THEN stopping. That's what I find...

I have a 6 year old Dolphin Discovery that is most likely dead. I'm looking for recommendations for a new cleaner. Here's the situation: - I'm not set up for a pressure-side cleaner and don't want to go that route. - The pool is vinyl-lined and I use a SWG. It's a 20x40 rectangle with clipped...

I have a Doheny Dolphin Discovery; I believe it's equivalent to the Maytronics S200. This will be its 6th summer. It worked fine last summer and was stored in my garage over the winter. I built my own power supply for it that has worked flawlessly for a few years and is outputting the required...

@Turbo1Ton - Thanks for looking! Like you, I've come up with nothing, and agree that it's most likely proprietary.

@ribbonofblack - Apologies for the delayed response. Unfortunately, I haven't found a suitable swivel. Regarding the power supply, it's very simple. My vacuum runs on ~30 VDC, so I purchased a power supply (https://www.amazon.com/gp/product/B07SY7HFJX) and a wifi switch...

Hi. I have a Doheny Dolphin (circa 2017) that does not have a swivel cable. I'm getting sick of having toe t constantly untangle it. I'd like to upgrado a swivel cable, but all I've been able to find online are entire cable assemblies for ~$200. All I need is the swivel. I have a feeling this...

Thanks, everyone! I'm familiar with the SWCG bubbles. Until we had the crushed return line replaced, I was running aboveground plumbing and noticed bubbles being produced anytime the SWCG was running. Now that we're back to underground plumbing, I guess the SWCG gas is building up in the...

I have two returns in my pool. I just installed Infusion venturi jets on both. When running the pump on low (1500 RPM, 20 gpm, 3-4 PSI) I noticed that both returns make an intermittent popping or "burping" sound, and both produce a small amount of bubbles. Clearly, air is coming from somewhere...

@ajw22 , @JamesW - Thanks for the replies. I'm going to try to remove what I can without popping the cover and lowering the pool. There's not enough water on the top to submerge a pump. I might try to brush it off.

We have a Meyco pool cover. We got a lot of rain this winter, so the water level in our (closed) pool is quite high right now. We're not planning to open it until ~Memorial Day. About 10 days ago, we had heavy rain. As is normal for any trampoline-style cover, the rainwater pooled in the middle...

Ha...I'm an idiot...10 ml sample is correct.

Just installed a SWG this year. Have been running for about three weeks and the water has looked amazingly clear the entire time, with no signs of algae forming on the walls or anything. So far, I'm VERY pleased. Per this site and the SWG instructions, I started adding granular CYA to the pool...

Was testing my water for salt content today using the Taylor K-1766 kit. Prior to today, I've never had a problem with this test. FYI, I'm using the Taylor stirrer. Filled the cylinder with 25ml of water, added the drop of yellow and started adding the other drops. As soon as I added the first...

This is the salt I used - Diamond Crystal® Solar Naturals® Water Softener Salt Crystals | Diamond Crystal® Salt. I added the salt on Sunday morning, and the pump has been running 24x7 since then, albeit at low speed (~20GPM). No floor drain. Pump is pulling water from the skimmer. In...

Recently installed a Crystal Pure PL7703 SWG. My pool's volume is about 27K gallons at the current water level based on my calculations, but I err on the high side for Pool Math purposes because I'm not 100% confident in my math. So, according to Pool Math, to take 30K gallons of water from 0...

Thanks, everyone. I ordered the K-1766 test last night. I had ordered a digital meter, but didn't realize it's primarily for seawater and doesn't have sufficient resolution for pool water. @JamesW - Thanks for those details. Most of what you typed isn't in the manual - or at least not the...

Last week, I installed a Crystal Pure SWG (model #PL7703) for my 30K gallon pool. Finally got around to adding the salt today (was sanitizing with bleach) and am starting to dissolve the CYA. I added 900 pounds of salt and swept it until completely dissolved. 12 hours later, the SWG's instant...

First season with a SWG. I'm planning to run it 24x7 and am wondering if that's a terrible idea. Here's the background: I have a variable speed pump that displays watts of electricity being used. I also have a FlowVis flowmeter. Every season, I check the flow in 100 RPM increments and determine...

Thanks for the help! I completely forgot to do the OCLT last night/this morning, but I did backwash yesterday morning and the system ran at 12-13 PSI and ~60 GPM all day. As you suspected, looks like the filter quickly clogged cleaning out all the gunk in the water from the winter. Water was...

This makes perfect sense to me...except, why does the problem seemingly reset if I turn the pump off for awhile? If algae is clogs the filter, the filter should stay clogged until I backwash, no? As I said, if I turn the pump off for several hours and then turn it back on, it runs at 12 PSI/60...

I don't doubt what you're saying, but can you describe how algae causes this behavior? The water looks good (not to say there isn't algae), and I don't have the ladder or anything else in the pool where algae typically hides. I also shocked the pool to a high FC value on Sunday (haven't checked...

Just opened our pool for the summer. Water is already looking great, and I successfully installed a SWG, but I'm struggling with an apparent air leak. Here's what's happening: - Turn the pump on. System runs at ~12 PSI and ~60 GPM. - Over the course of two hours, pressure climbs to ~20 PSI...

Installed a Crystal Pure SWG from INYO today. Everything was going smoothly until I glued one of the unions for the salt cell without the nut. My pool is plumbed with 1.5" pipe. The kit came with both 2" and 1.5" unions, but it looks like only 2" unions are available separately. Anyone have a...

Planning to convert my pool to salt water this season. I'm in NJ, so I've got a few months to go before I open the pool. Doing my research now and am leaning towards the Hayward AQR15. Reviewing the manual, it clearly states that the system must only be powered when the pump is on. The manual...
