One thing that seems strange is that my water level on my brand new 2023 Bullfrog A6L (310 gals.) hot tub has been dropping an average of 16.5 gallons per week (2 1/3 gals/ day) in the 23 days since I turned the heater on to heat for use after the water balancing process on 2/8/24. When I noticed the first water level drop on 2/10 I added 14 gallons. The weather and cement pad were dry, so I assumed it was not leaking. I immediately checked to see if the ABS plastic pan was filling up, but saw there are 1/2" holes in the bottom of the pan in the equipment area, so water would escape there. I don't know if it is safe to assume those 1/2" holes in the bottom of the pan would be spaced throughout the pan's bottom surface area, not just in the equipment area, or not. The pan I could see from the front equipment area was completely dry, w/ no signs of water. On 2/15,I added another 20 gallons. Today, 3/2, I added 20 more gallons because I noticed that the water level was down ≈ 5/8"-3/4" from the recommended fill line. Today was the third time I added water, for a total of 54 gallons to date, since I had turned the heater on Feb. 8th, after completing the water balancing process.
On 2/10, when I first noticed that the jets would spray out of the tub for a second when pumps were set to high, I looked and saw that the water level had dropped a half inch or so, so I added water to bring it back to the fill-line (there is a mark in the middle of the filter inlet bezels). Before that, I had to run many 30 min cycles with jets on full to raise the PH, then add acid to drop it again over a two day period. I needed to get my tap water's TA down from 370 ppm, so that took two days with the cover off during those 30 min aeration cycles. I guess evaporation might have been part of my first water drop (but water was +/- 60º F, so not hot).
I have gone in maybe 12-15 times in the 23 days since it started to heat up 2/8. Is this considered within an acceptable range of water loss? Even if there was a water leak and water was leaking into the mostly foam filled area(s) around the tub, it is hard to imagine that the 100% closed-cell foam would absorb any water, let alone 50 gallons without draining some into the ABS pan and out onto the concrete pad. 54 gallons is ≈ 17% of the 310 gallon initial fill to the recommended fill line.
Per the Bullfrog website, they use: Full Foam Insulation. Bullfrog Spas’ 100% closed-cell, full foam design insulates the spa completely to prevent heat escape, even in the coldest climates.
I'd appreciate any insights for this newby.
