Hi everyone, Our pool plaster (plain white) is over 17 years old, and it appears that it's time to re-do it. We now have some dark stains in the deep end that appear to be rust and I'm thinking that it's from the rebar underneath. A chlorine puck is not fading them at all, so I don't think...

Hello, I pulled my light fixture yesterday because I could see some water behind the glass. Less than a year ago I replace the bulb and put on a brand new gasket. I was pretty careful to follow all of the steps properly. Because the gasket was new, I'm wondering if my fixture is now leaking...

Hello, Looking at replacing my old incandescent pool light with a J & J Color Splash LXG-W. It has the multi colors and also a separate dedicated white. I have noticed that there are a couple of different part numbers out there for what I'm looking to buy: LPL-P2-RGBW-120 and LPL-P3-RGBW-120...

Hello, I have a Pentair Intelliflo VSF pump and a Jandy Aqualink automation system (older RS4 recently upgraded with the IQ-30 kit). For the most part everything seems to be running fine, but I do have a question about using the pump's controls. With the automation connected, the pump's...

Hi folks, after years of owning my Jandy Stealth pump I had to replace the lid. The older Jandy lids (like my original one) had an o-ring which I always kept lubricated. The new Jandy (Zodiac) lids no longer have an o-ring but rather have what they call a 'lid seal'. It has a rectangular...

Hello, I am getting ready to purchase a new blower pressure switch for my Jandy LX400 heater, but I wanted to see if I could get some advice here first. When trying to use the heater I get an 'air flo sw' error on the screen and it shuts down. But the blower appears to be working perfectly...

Hi everyone, I've had my Jandy LX400 heater for almost 10 years now, and I ran into an issue the other night when attempting to use the spa. The GUI panel indicates that I have an air flow sw issue and the heater will not stay on. The exhaust area is clear for exhaust air flow, and the blower...

Normally the TA in my pool is somewhere between 80-100. Today I did a complete set of tests and to my surprise it measured 60. I did the test twice just to double-check. Now, normally a TA of 60 would likely mean some kind of correction is in order, but in my case I'm not sure. My water here...

Hello all, I'm wondering about doing a no drain acid wash due to the recent appearance of my plaster. The plaster is about 10 years old now, and a few months ago it started looking 'dirty' on the bottom. I'm not sure if it's some kind of staining, or something precipitated onto the plaster...

Hello, in addition to the circular Jandy check valve that we have in our plumbing, there is another see-thru component that now leaks (sprays, actually) water when I backwash the filter. I have attached a picture. Is this another check valve? To fix, can I loosen up the barrel nuts and take...

I'm curious about the salty taste we have in our pool water. We do not have a SWG. A few years after the pool was built, we noticed that the water had started to taste just a little salty, and in the 4th year it started to get more noticeable. We drained and replaced a lot of the water, and...

Hello all, I have a question regarding backwashing my DE filter. I have a relatively small pool (~12K gal.) and a 60 sq. ft. DE filter. I believe this is a pretty large filter for the size pool that I have, but I'm assuming that's probably a good thing. Anyway, my plan is that I try to take...

Hello. When my pool was built, the installer plumbed in a Pentair Rainbow 300 offline puck feeder. I don't use it, but I have just left it there because I figured that removing it would involve trying to plug up the installation holes in the pipe, or cutting out sections of pipe and putting...

I have a 6 year old Jandy Stealth pump, and as of today it won't start anymore when power is applied. It will hum for a while, then it shuts down. I can't really reach the impeller by sticking my hand and arm in the pipe, so I'm thinking I may need to take the pump cover off to see whether or...

I need to repair or replace one of my Jandy JVA 2444 valve actuators. From my observations so far, it appears that the motor runs but the 'toothed' shaft on which the plastic cams are mounted is not turning. So it appears that there's an issue with the coupling between the motor and the cam...

Long story short...I replaced my pool light bulb and gasket about 2 months ago, and it looks like I'm going to need to replace the bulb again. After such a short period of time, can I keep the same gasket (provided it looks OK upon inspection)? Thanks, Greg

It appears that I have a pool light issue that seems a bit strange (to me, at least). Our pool was completed about 5 years ago, and earlier this Summer I noticed that our main pool light, a Pentair Amerlite, was getting dimmer. This seemed strange to me...I figured the failure mode would...

Hello, not sure if my CH is really this high or if my testing is not accurate.... Our tap/fill water is normally quite hard (tap can often be 300-350 ppm or more). For the last couple of years, anytime I've measured the CH of my pool it's been in the 350-375 ppm range. Because it's been very...

I need to spray/apply some muriatic acid on my tile in a few places to remove some calcium buildup, and I want to make sure that I don't damage the tile grout while doing it. Can the acid/water mixture stay on the tile for a while before rinsing it off, or will the grout start to get eaten away...

I've got a question about buying replacement reagents. I went to a local store today and bought some Taylor replacement reagents for TA testing (R-0007, R-0008, and R-0009). Just for the heck of it I called Taylor and had them check the lot numbers. One of the reagents was indeed considered...

Given that my pool gets a good amount of sun each day (I'm in Southern Calif with a South facing backyard), can someone tell me roughly what I should expect for a percentage FC loss during the day (if nobody used the pool), given a CYA level of 40 ppm? Better still, if there's a thread...

Not that I'm complaining, it was actually a nice surprise not to have to add muriatic acid today as I was expecting. This week I shocked with liquid chlorine; I think I dumped in a total of 7 gallons over a few days. Everything looks great, and my FC levels are now nearly back to normal. But...

I had this going on another thread, but there were two issues going on simultaneously and to avoid further confusion I wanted to post my latest results on this topic now that I've tried new reagents. Basically, I'm having trouble getting the titration to "finish" properly when performing the...

water sample cloudy after adding DPD powder I know I've seen this mentioned in the past, but I can't find any relative posts right now.... Normally when I add DPD powder to my pool water sample, the sample stays pretty clear (I can very easily see some of the loose DPD granules swirling around...

I'm in the process of trying to detect a suction-side air leak, as my pump won't hold prime when it's shut off and there is air in the pump basket area when the pump is on. I have noticed that when I put the pump basket lid back on, it's easier to turn all the way to the closed position than it...

I think I have an air leak somewhere, but I'm not quite sure. My pool and equipment are about 2 1/2 years old. About a month ago, I noticed one morning that shortly after our pump turned on that it sounded like it was priming itself. I went and looked and it was nearly full but was still...

Hi folks, I have a 60 sq. ft. Jandy DE filter, and I take it apart every 6 months and clean everything out and replace the DE. My question is, if the pressure gauge never goes more than a pound or two higher than the "clean" setting between my 6-month cleanings, is there any reason that I...

Please bear with me.....I'm still trying to figure stuff out... I'm wondering if my new bottle of FAS-DPD titrating reagent is suspect, or if I really am losing as much FC to sunlight as it seems from the test results. Yes, my CYA is quite low right now (I know it's under 30 from the test, but...

I just started using a new 2 oz bottle of the FAS-DPD titrating reagent, and I've noticed that when I turn the bottle completely upside down, a drop will quickly form and fall down into my sample without me squeezing the bottle at all. Sometimes it looks like a second one will also form and...

Hi folks, I apologize for being lazy...I imagine there are posts on this somewhere here already, but I'm going to ask... My Taylor K-2006 kit is now a year old. The chlorine and pH level reagents have already been replaced, and will be again soon, as those are used the most often of course...
