My Dolphin M500 finally died, so I got an E70. Since I was very happy with the M500, I figured I'd love the updated (and expensive) E70. During its first run, it got stuck on the main drain, and continues to do so almost every time it runs. I'm communicating with Maytronics, but their first...

I'm trying to replace a Globrite bulb that burned out. I can unscrew the old bulb easily, but once out, I can't pull the bulb out any further than a couple of inches. I pulled as hard as I can, but it doesn't budge. There is plenty of slack on the other end. Any ideas? Am I missing...

Being super bummed that Pentair doesn't yet have an Apple Watch app yet for Intellicenter, I recently installed an IntelliCenter plugin on my HOOBS (HomeBridge). It works pretty good! Since there is a Home app on the watch too, I can do the things I used to like to do from my watch (change spa...

Quick one...Change the default on the FC section for SWG to be Pump Hours instead of SWG Cell %. Most people probably have a set number of hours they run their pump and then change the % when needed, vs changing the pump run time and keeping the % the same. A bigger one is to re-design how the...

I'm trying to figure out how much calcium my pool will add daily due to evaporation and re-fill. Here are the variables: Tap water 80ppm I estimate I'm losing 167 gallons per day My pool is 20,000 gallons How many ppms will my calcium increase per day? Do you take 167/20,000 = .00835 and...

The city requires a back flow preventer be hooked up to my autofill line. The pool builder installed one. The problem is that, fairly often, it starts to vent water from the CITY side. I know it's from the city, because I tasted it (not salty at all) and also my pool water level was well...

Wanted to start a thread with known changes in 2.006. Let’s keep this thread as clean as we can with changes. Other threads can be used for discussions. Please add to this list. - BUG FIX: Freeze protection now persists even after a power failure - BUG FIX: IntelliPH now recognizes when...

I’ve developed a very small leak in my multiport valve, right where the handle connects to the valve. The leak is so small, it barely dampens the ground below it. My question is…should I get ahead of this problem and replace it now, or wait if/when it starts to leak more? Or…is there...

I know that if your clean pressure rises, it's time for a deep clean. What if it doesn't, but has been over a year since you did? My clean pressure is the same as the day I installed it, but it's been a year since it was disassembled and throughly cleaned out. Time to clean it, or let it be...

I try to keep my CSI slightly negative to help reduce calcium buildup on the cell. Is this just helpful when the cell is in use? My pool water is too cold right now, and likely will be for another month or so. I'm using liquid chlorine while the pool water is too low. Is calcium buildup on...

My CH rises over time. I’ve turned off my auto fill and now add water exclusively from a water softener. Most recently, my CH went from 600 to 675 despite not adding any water, and I actually had to drain some due to rain. Where is the CH coming from? Is it leaching from my plaster? Is this...

My Dolphin M500 will turn on, and then sit in place, turn around in a tight circle, sit in place, then shut off. Total cycle lasts a few minutes. I thought one of the rollers was stuck, but I turned it upside down and turned it on. Both rollers turned in opposite directions (trying to spin)...

Hi all. My heater has been cycling on/off when the water reaches about 85 degrees. I read a few threads on here on how to troubleshoot. I originally thought it was the high limit switch, but I replaced it and it was still shutting off. I then removed the thermal regulator (see pic) and now...

The board on my IntelliPH fried for the second time in about a year. The warranty service company came out today and is now telling me that Pentair says the IC60 pulls too much current for the IntelliPH and Pentair wants to swap out my IC60 for an IC40. Would an IC40 work? Sure, but I’m not...

I happened to glance at my IC60 the other day and I noticed it was in salt measuring mode. The manual states that it checks every 12 hours or right after powering up. Neither of those were true at the time. Since then, I’ve been looking at the reported salt level in my IntelliCenter app. It...

We are an Apple family (my wife works for Apple). I would really like Siri control of IntelliCenter. I found a ScreenLogic Homebridge plugin, but not one for IntelliCenter. Anyone know if one was created? Anyone want to write one?

Anyone develop a cost to run your pool spreadsheet? Pool store (pucks plus weekly shock plus algecide/clarifier vs TFP (liquid chlorine/SWCG & Muriatic acid)? I’m a finance guy and TFP advocate. I’m envisioning this to be a different kind of “pool math” page. The end result is that not only...

I was curious to see how high salt levels get in non-SWCG pools. Anyone test their levels either for the heck of it, or because they were going to install a SWCG and wanted a starting value? If so, post your level along with an approximate length of time since initial fill and/or partial...

Anyone know of a good outdoor, non powered water softener I can install for my autofill? I’m not sure I want to invest in a whole house model. I’ve seen some non-powered versions, but not sure if they are worth it. My fill water is about 80PPM of calcium, not as bad as some in AZ, but my...

What’s the trick for putting this back in? Doesn’t appear to be threaded and I also tried to push it in. Also, which way does the black washer go? TIA!

If I have an Intelliph installed right before my SWG that pumps in a little acid every hour, do I have to keep my CSI slightly negative to reduce scale on my SWG? Or can I safely run my CSI a little positive (still staying below .30)?

I’m having some siding work done on the house and there are 2 nails in my pool I can get out. My robot can’t either. So...my plan is to run the heater all night (current water temp is 56) and go in tomorrow and get them out of the shallow end. They fell in today...is waiting until tomorrow...

I highly recommend the IntelliPH! If you don’t have automation and are a DYI kind of person, a generic container and pump is certainly cheaper. But, if you’re like me and have Pentair automation already and battle high PH, get it! I have a new plaster pool (finished March 2019). I told...

So, I was having this discussion about how traditionally chlorinated pools end up with a salt level that approaches that of a “saltwater” pool because when chlorine gets used up, it turns to salt. But since I’m not a chemistry expert (but their son just graduated from college with a chemistry...

My build thread is here: New Pool Build in Austin (Feedback welcome) I was waiting until landscaping was done before posting final pictures. We’ve had water in the pool since mid March. I just noticed a slow leak in the spa. See pic: In hindsight, I should have figured it out a few weeks...

I know the pump needs to be running when adding chemicals, but what about when taking the sample? Does that matter?

How bad for the pool is it if some of this gets in the water? https://www.homedepot.com/p/Custom-Building-Products-Aqua-Mix-1-Qt-Non-Cement-Grout-Haze-Remover-010900-4/300176059 I need to clean the big retaining on the side of the pool. At most 4oz in a 20,000 gallon pool. No big deal, correct?

I’m struggling a bit with the R-0014 PH comparator. I saw this one on Amazon that uses the R-0004 reagent instead of R-0014. Has anyone tried it? I have a new plaster SWG pool so I’m struggling with quickly rising PH. I want to wait until it hits 8, then drop it to 7.6. My current...

I’ve had water in my new pool about 45 days now. SWG is humming along. I think everything looks good. My only issue is negative CSI. Here are my numbers: FC: 7 CC: 0 PH: 7.8 TA: 70 CH: 300 CYA: 70 Salt: 3400 Temp: 73 CSI: -.24 I know that a CSI of -.24 is ok, but in order to stay above...

Pool math says -.3 to .3, but I’ve read here that down to -.6 is ok. It’s just the negative side I’m concerned about. I can get there, but I don’t have much wriggle room. So...how bad is -.45? Thanks.
