    Spa jets stop working for overflow into pool

    Hello. I have a VSP running 24/7 at various speeds and at some point during the day overflow from spa into pool stops working. The filter pump is on, the pool returns are flowing water, but the spa returns have stopped flowing water. I don't believe that the stoppage occurs in alignment with a...

    Rust markings along pool bottom

    Hello. These rust marks have started to appear along the bottom of my pool. Could these possibly be from the rebar given their shape/size? If so, is there any major concern? It's not ideal, but I can live with it from an aesthetic perspective. I am more concerned about whether it is something...

    New Pentair Intellibrite Lights Not Connecting to Alexa

    Hello all. I have an iAqualink RS system and recently changed out my white lights for Pentair Intellibrite colored lights. The Pentair lights are controllable via the iAqualink app, but the voice control through Alexa is not working. I tried disabling the iAqualink skill in Alexa and...

    Pebble-Tec Fading

    Pool is in its 4th season. Admittedly, I question the contractor’s diligence when handling the pool startup. I made the mistake of learning how to maintain on my own later. A pool guy had told me a couple years ago that the area where the wall meets the pool bottom is fading because of the bad...

    Calcium Hardness Level Question

    Hello all. This coming summer will be our fourth summer with the pool (built 2020). I took over maintenance two years ago thanks to all the helpful folks here and have seen significant improvements so...thank you! My question now is about CH level. I have historically had CH levels on the...

    Having a hard time with Calcium Hardness test on Taylor K-2006

    Hello all, I am having a heck of a time getting results I can rely on when testing for calcium hardness. I follow all the steps, but sample never really changes colors from red to blue as indicated on the instructions. It does turn a kind of purple, which is what I have been relying on, but...

    AquaPure Replacement 700 to 1400

    Hello. I have a 16,000 gallon plaster pool with an AquaPure PLC 700 that I think has died. Chlorine levels have dropped and I am getting error codes 125/194. The unit was installed in April 2021, but looks like the installer undersized it for my pool. When replacing I’d like to correct that and...

    Error Code Went Away With Lower Pump Speed

    Hello all, I used to run my variable speed pump at 1500 RPMs about 10 hours a day in the summer and 6 hours I’m the winter. My Jandy SWG regularly gave error codes 120 and 121 but it did not affect chlorination so I never acted on it. When I first observed the code I cleaned the cell, but that...

    How much muriatic acid can I add at a time?

    Hello. I have a two-year old 16,000 gallon plaster pool with a dark pebble-tec finish. The pool guy has stopped coming around and I've taken over maintenance duties and balancing my chemicals the past several days. When I started, the pH levels were high so I have added two pints of acid a day...

    Proper Salinity Level

    Hello all. I installed a Jandy PLC700 Salt Water Chlorine Generator (SWCG) last summer and it has been operating wonderfully. It took a while for the salinity level to drop to a point where I needed to add salt and I did so a few weeks ago to raise it from 2.8 to 3.5 (according to the Jandy box...

    Considering Robotic Pool Cleaner - Thoughts on Quantum?

    Hi all. Considering an automatic vacuum and looking for robot recommendations. Pool is approx. 16K gal and rectangular in shape with a Baja deck. I recognize most robots won't hit the deck. The pool guy hardly stops by anymore, but that has been fine since installing the chlorinator. I am...

    Does Vinegar Damage Jandy AquaPure Sensors?

    Hello all. Today I completed my first cleaning of my Jandy PLC700 SWCG in response to error code 120. When looking through various tutorials I decided to go with the less corrosive vinegar route, but I did not remove the sensor from the side port of the unit. I didn't realize until after soaking...
