OK! You were right! (Sounds like a conversation with my wife.) :oops: Two thumbs up to Pentair warranty service department.:goodjob::goodjob:

The end to the story: After an initial slow response, Pentair stepped up and did the right thing. They finally got back to me (via email) and dispatched a warranty service tech. He showed up this morning. He quickly determined that the IC40 circuitry had "died" and he immediately replaced the...

Yes, I added a bit of salt when this began. Raised my level from 3200 to 3400ppm. I know the IC40's salinity calculation reads about 4-500ppm low. I finally got a response from Pentair yesterday AM. They're asking for receipts, etc.. They may replace it under warranty. Fingers crossed! BTW, I...

mknauss, appreciate the info on the IC40 salinity generation values. However, my pool salt level is 3400ppm as measured 3 days ago via the Taylor K-1766 kit. Something is still wonky in my SWG. I did notice that the start up sequence seems to take a bit longer than the "normal" 2 minute cycle...

Dirk, appreciate the info on temp sensors. However, the SWG weirdness continues! I replaced the flow sensor with an aftermarket brand. It worked fine for a day. Now the red "Low Salt" LED is back on! The SWG appears to be producing chlorine (bubbles in return water and maintaining FC level) but...

A little techie info for those who care: I discovered that the thermistor built into the flow switch is a negative temperature coefficient (NTC) type. Meaning as the temp rises, the resistance drops. Evidently, the Pentair thermistor is set for 10 kOhms at 77º F. I took the bad flow sensor out...

The saga continues.... Today, I went out to do my daily pool check. I noticed there were NO lights illuminated on the IC-40. I began troubleshooting and discovered the IC-40 transformer fuse had blown. I replaced that fuse, reenergized the panel, and restarted my pool equipment . The IC-40 did...

I did the install myself. The Pentair website doesn't require "professional" install for 2 year warranty. You get an extra year with pro install. I'll try calling but being a holiday weekend with COVID, etc, etc, etc., not confident about reaching anyone. Thanks for the input!

Thanks. I'll order new aftermarket flow switch today. Is there any way to test the thermistor, e.g., with a multimeter?

Thanks for the rapid response! I purchased the IC40 in late August 2018 off Amazon. According to Pentair website, their SWGs have a 2 year warranty when purchased alone. Looks like I'm out of luck for a warranty repair. Guess it's time to try a new flow switch/thermistor. Any issues with...

My Pentair IC40 SWG suddenly started to show the red "Low Salt" warning light two days ago. I checked my salt levels via the Taylor K-1766 kit. Two tests came back with 3400 ppm, so I know the salt level is not low. I checked the plates on the SWG and they did have a small amount of scale on...

When I installed my SWG about 6 years ago, I had a similar problem. The pH was climbing almost daily due to the carbonation effect in the SWG. I solved the problem by installing a Pentair IntellipH acid injecting system. My pH is now extremely stable (7.4-7.6) because a small amount of MA is...

Richard is absolutely correct. The lack of "sparkle" is due to high pH and low FC. My pool is currently at 750 CH and I have to get to 7.4 pH with a TA of 60 to keep the "sparkle". Since I'm using an SWG, I put in an IntellipH acid injector in 2015 to keep the pH under control when I cannot be...

I've used it with good success on PVC and other plastics. The surface must be clean of dirt and other contaminants (grease, etc.) but it seems to adhere very well and hold its color out here in the hot desert sun.

Thanks. Not sure what part of the pump is the problem. The pump is part of the Pentair IntellipH system. I believe it is a Stenner EC30 pump or OEM custom equivalent. Sending an email to linked address also. Thanks for chiming in!

Thanks. Didn't think that venturi effect was used for the Stenner pumps but was unsure if end of injector could be cavitating from speed of water flowing past the injector. Have to rig up something to test the pressure in the peristaltic tube. Time to put my engineer's hat on.

Recently a problem with my Pentair IntellipH system surfaced. The IntellipH pump is running as scheduled but the MA isn't flowing through the injector to my pool. I've replaced the rollers (new version of IntellipH with Stenner EC30 pump head), replaced the peristaltic tube and the duckbill...

Welcome to TFP! :wave: While every pool is different, if you look carefully at the FC/CYA chart, you'll note there are separate recommendations for an SWG pool and a non-SWG pool. The primary reason to maintain a higher CYA level in an SWG sanitized pool is to prevent the chlorine "burning...

Chlorine is chlorine. The only difference between bleach, dichlor tabs and an SWG is form of chlorine. Chlorine likes to be a gas at room temperature. Bleach is nothing more than gaseous chlorine dissolved in water with caustic soda (sodium hydroxide) giving us sodium hypochlorite. The problem...

As far as which robotic cleaner is "best" goes, it is always a cost vs. warranty vs. personal preference decision. This forum is devoted to robotic cleaners: Automatic Pool Cleaners. Spend a few minutes reading the comments in this forum. I am partial to Maytronics as most of their mid-priced...

I own an A & A In-Floor Cleaning System (IFCS). It has been essentially trouble-free for 7 years. However, had I known about how efficient robotic pool cleaners were, I would have NOT installed an IFCS. The extra complexity in plumbing, the IFCS moving parts, and the higher pump velocities...

In reality my electricity use for the pool is about $1/day. I estimated this based on the Tucson Electric Power (TEP) average cost of $ .09/kWH. Not bad at all. However, I think I may be unnecessarily stressing the floor cleaner and the pump by running it at those speeds for so long.

Been thinking about how I'm running my pump, SWG, floor cleaners and skimmer. If you note my sig, I have an EasyTouch panel and QuickTouch 4 remote (as well as an Autelis WiFi controller). Currently I have only two programs (circuits?) set up, a low speed (1600rpm) for the skimmer and a high...

My gear set has two gears in contact with the teeth in the lower housing. I had no luck with A & A so I ordered a rebuild kit (Part # 540277) out of pocket for the replacement impeller, gears, washers, o-ring and shaft. I removed the old gear set this morning and compared it to the new one...

chiefwej, Thanks for the offer. I'm gonna work with A & A to fix this. I have a robot cleaner so the in-floor is not truly needed. I'm going to ask A & A for a rebuilt kit to replace the entire gear assembly and washers. Thanks again.

Contacted A & A via email (phone call went to voicemail). They sent me a PDF with troubleshooting steps to follow. Already did everything they mentioned. The impeller is still not moving in a smooth, consistent manner and it stops after about 1 minute regardless of the pump speed. Because the...

I have the low profile side-feed, 6 port valve. I don't have a leaf vac. A small amount of air bubbles have always been visible in the valve lid. I did clean and relube the pump basket o-ring yesterday thinking there could be a small suction side leak also. No other bubbles appear in the pool...

I am the original owner of the pool/equipment. I was unaware that A & A had a lifetime warranty. I'll call them tomorrow. I was aware that rotating the lid position will change the cycle speed of each zone. The one area I di not inspect closely was the lid itself. Is it possible a crack or...

The small gear under the impeller was fine. I removed all the gearing and tested it dry to be certain everything was meshing and moving properly. It appeared to be fine. I am the original owner of the pool. I was unaware that A & A had a lifetime warranty. Thanks!
