Inspected spa nozzles light and drain for leaks. Did not see anything obvious. However, I drained the water low, and saw a wet spot on the inside of the hot tub at the 630 position. Just above that, there is a little hole in the mortar.

First test of rainwater fill system. Easily 5 gallons per minute per pipe at the peak flow. Initial water was a little yellow then ran clear. From the downspout, pH was 7.3 and CH less than 25. Per the internet, with roof of roughly 1,000 sq ft, you'd get 620 gallons per inch of rain. We got 9/16", so about 350 gallons.

TFP says to backwash when 25% higher than starting pressure. For 15 start, that would be 19 psi.
