My pool problems actually started before the anticipated major drop in temps. I went out last Saturday to get everything ready for the storm and I noticed that the freeze protect had not worked AND the spa was super low for some reason. It was already completely frozen (and yes, we will definitely have to replaster). The water in the pump basket was also frozen. The sun was going down, as well as the temps, so I just made sure the pool level was up and turned the breaker off. On Sunday morning the entire pool appeared to be frozen but I was able to thaw the water in the pump basket and drain it, per advice I received here. Unfortunately I couldn't get the drain plugs off the filter or heater. Frozen solid. We had rolling blackouts for the next 4-5 days. Power on for 30 mins, off for 60 to 90 mins. Fast forward to today, everything is thawed, it's fairly warm & some people are wearing t-shirts and shorts again. I haven't even scheduled a pool inspection yet but decided to fire it up to see if I could determine what damages we are looking at. The pump and filter seem to be fine. Heater is not. Water was spraying from the bottom enclosure, or maybe from the heating element?? (see photo) Obviously, I need to get someone out to inspect everything but I'm curious what you guys think. Is there any hope? I only ran it for a few minutes to see if there were any other obvious issues but it's hard to tell with the heater spraying water everywhere. I haven't tried the pump for the Polaris yet, but it was already on it's last leg so I'm not expecting much from it. Is it possible to bypass the heater, so I can run the pump for a bit longer, to see if there's any other areas of concern? Recommendations for a replacement heater? It looks like if I were to buy the exact same one (or most similar), they cost about $2500 online + labor. We are probably going to sell the house within the next year so if there's a less expensive one for almost the same quality, I'd like to hear about it. Our current heater is sta-rite 400k btu natural gas model SR400. Pool is 17k gallons but ... it's Texas. Rarely do we heat the entire pool. Just need a decent one for the spa.
