    Pentair Intelliflo VS+SVRS Pump Won't Come on Automatically

    Hey all, I went back and checked all of the valves, which all looked like they were in the correct position, but actually one of them had gotten bumped and was ever-so-slightly moved (like less than 1/8") so I move it back into position and ever since, the pool has come on at its scheduled...

    Pentair Intelliflo VS+SVRS Pump Won't Come on Automatically

    I recently started using my inline chlorinator again. Is it possible I did something wrong and it's causing the pump to fault?

    Pentair Intelliflo VS+SVRS Pump Won't Come on Automatically

    Thanks for your replies. I checked the skimmers (empty) and doors (not blocked, moving freely) and valves...all are fine. The water level is a bit high due to recent rain, so I'm getting ready to drain some out. I've had an issue before when it got too low and the pump shut off. High water...

    Pentair Intelliflo VS+SVRS Pump Won't Come on Automatically

    Hello! A few days ago, my pump stopped coming on at the regularly scheduled time of 9:30am. My cleaner is set to come on at 10:30 am. There is a "Blocked System" alarm. I'm able to manually start it using the panel. I shut the power off, take the lid off the filter basket, put it back on...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    This thought had crossed my mind! I’m so glad you said it. I’ll run it in spa mode and see what happens. I’ll also drain it into the pool. Thank you!

    Thanks, Thanks for your help and advice. It’s much appreciated. I’ll be cleaning the filters next.

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Thanks...although that's not what I wanted to hear. Normal pressure is between 20 and 30, and I recall that it's usually right in the middle after the filter is cleaned. It's at 20 now. Probably a dumb question that I could Google, but I'd appreciate your opinions: is it dangerous to swim in a...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Another Update- Here are today’s results after adding water: FC 7.5 (added 3 quarts liquid chlorine) pH 8.0 TA 100 CH 450 CYA 110 (did the 50/50 test and level was just between 50 and 60) CSI .52 (potential for scaling...) this has crept up I've been maintaining my pool since I partially...

    Thanks for the encouragement! We would switch to a SWCG if we weren't planning on moving within a year (hopefully). I wish we had done it originally.

    Thanks, Felipe and Jeff. I'll keep an eye on the chemicals every day. So I don't have to be too concerned with TA @ 110?

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Sorry, I guess I meant to add "due to the high TA." That's For TA, Pool Math says to reduce pH to 7.0 to 7.2 with acid, then aerate to increase pH (I think this is my answer...?) For pH, it says I need to add a pound of Soda Ash. What do you think?

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Update: Yesterday I added 3 lbs of soda ash (not the 7 recommended by the Pool Math app), and here are the results: FC = 12.5 (same) pH = 7.4 (up from 6.8) CH = 425 (same) TA = 110 (up from 90) CH = 425 (same) CYA not tested (has been 120 using 50/50 split) Pool Math is giving me conflicting...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Update: Yesterday evening I added 2 gallons of liquid chlorine (12.5%) This morning the chlorine was > 5.0 and pH was >8 on the daily test. A few hours ago, I had someone come to clean off the calcium buildup, which lowered the pH to 6.8. Here are my latest test results (water temp 84/air 80)...

    Yes, I saw the warnings on the tarp method and decided against it. Thanks.

    Good to know. So basically CYA is a water only problem.

    I'm going to add 1 gallon of 12.5 liquid chlorine now, then test later in the evening. Will test all chemicals tomorrow.

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    Great idea about the rain suggestion...thank you. I simultaneously drained/filled using the recommended method on TFP. I'm sure that the CYA was extremely high, probably 400 as you suggest it might have been, but at least now I'm fairly confident in the 120 reading from this morning (with...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    With these numbers, do I just need to add chlorine (2 gallons?)? FC = .5 (CC = 0, TC = .5) (yesterday = 1.0) pH = 7.5 (same) TA = 90 (yesterday = 100 CH = 425 (yesterday = 450) CYA = 120 (used 50/50 pool/tap water, doubled result) (yesterday = ? 110) CSI = -0.10 (yesterday = 0.07) Now that's...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    What do you suggest for chemicals/amounts & order of application? I might do some more draining since it's possible I underestimated the size of my pool by a few thousand gallons, and I see that it will be better to drain too much over too little (except for my water bill 😭) I'm thinking I'd...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    I think my plan today is this: Do the diluted water CYA test Depending on results, I may drain some more water. (I'm expecting a very high reading) Then chemicals...BUT I need help with the order in which to add them.

    No I did not run the pump until after the water exchange.

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    MGuzzy - I followed these directions from TFP. The temp difference was only about 5 degrees (tap water here in TX is not very cold in the summer) and my CH was very high, so I pumped from the deep end/filled into the shallow end skimmer. I doubt that the fill water was colder than the deep end...

    I drained approx 2/3 of my water and my CYA is still high...@ 110!

    I guess I'll try to keep exchanging some water over the next few months and take advantage of any rain, and also not using chlorine tabs any longer. But I'm still REALLY confused as to why the CYA barely budged after replacing so much water. Will it ever get lower?? Also, we do swim into...

    I took a sample to Leslie's today and here are the results. They said to add 40 oz muriatic acid, wait 4 hrs, then shock the pool 3#. Interestingly, the sample I took to Pool Stop last week, before any draining, showed my CYA at 150 which they deemed "good" because their range is 30-200. WTH?
