    Urgent issue with freezing temps and an empty hot tub

    Thank you! I didn’t realize there was a toggle. And I need to do both these steps? I have barely ever touched the menu on the Pentair panel. Any chance you know the navigation steps to the spa circuit?

    Urgent issue with freezing temps and an empty hot tub

    Live in Texas. We have freezing temps not usually worried about that because we run our pump 24/7 and have freeze protect. The problem. Our pool has ASR/concrete cancer. It’s a whole other disaster. The hot tub will not hold any water as of last September. We drained it and turned the manual...

    ASR - Concrete Cancer - Austin, TX

    You may be right. I don’t have any exposed gunite to even see it that’s what it looks like. And right now for my pool, this is essentially cosmetic. I don’t have a leak. But I will tell you that ASR is growing problem here in Central Texas. Multiple pool builders are dealing with this all...

    ASR - Concrete Cancer - Austin, TX

    I do not know for sure that I have ASR yet. Only way to know is by doing a core sample. I’ve been told that costs 9k. So, not something to be done spontaneously. My pool currently is holding water. The pool builder is the one who is telling us they think it’s ASR. These are just some...

    Spa Waterfall not flowing when pump on low.

    Just wanted to pop back on here with a follow up. It was definitely clogged filters. New ones in places and everything is working perfect! Thanks again everyone.

    ASR - Concrete Cancer - Austin, TX

    Hi. I’m in Round Rock. Pretty sure I have ASR as well. Right now my pool is technically holding water. But I have cracks all over the place: decking, tile, coping, one confirmed in plaster and extends to exterior etc. Both skimmers cracked (now repaired). We had the pool company come out and...

    Spa Waterfall not flowing when pump on low.

    RPM on low is 2500. Which is higher than what some would consider low from my understanding? By “do the test” you mean remove the cartridges from the filter and run the system without them?

    Spa Waterfall not flowing when pump on low.

    ok I see what you mean that about the water flow to the spa. Not really sure how I could clog a large cartridge filter in 30 days. I am in central Texas. we've already been through our live oaks dumping all their leaves, that is a beast to keep up with. Cleaned the filter after that had...

    Spa Waterfall not flowing when pump on low.

    ok thanks for that advice. the filter was cleaned about a month ago. if the filter is clogged, why would it only effect the jet returns? Pool returns seem to be working fine in low mode.

    Spa Waterfall not flowing when pump on low.

    I have a spa that has a spillover waterfall into the pool. I have the Intelliflow VSP set on a timer to switch between hi and low pump speeds. Most of the time the pump runs on low which is at 2500 RPMs. Normally, the waterfall spills over during BOTH high and low speeds, just obviously in...

    Intermittent cloudy water

    I’m having trouble keeping chlorine levels up in my pool. During the winter I maintain my pool with 100% liquid chorine. But during the warmer months because of increased bather load, Texas sun, and my work schedule, I can’t add liquid chlorine every single day. So even though I know it’s not...

    Draining pool with Cartridge filter??

    Thank you. Asking you the same question as above. If I use asubmersible pump would I still need to turn the valves off to the skimmers and turn the pool pump off?

    Ok thank you for that. I will use a submersible pump. But would I still need to turn the valves off to the skimmers and turn the pool pump off?

    Draining pool with Cartridge filter??

    Pool is 1 year old. CYA is now ~100 (Taylor kit) . And I would like to partial drain and refill. Am I correct that I should close my skimmers, leave the bottom drains open and run the pump and let the water come out of this hose bib?
