Entire Pool was replastered and second drain added to spillover hot tub a couple months ago. I wanted to test for any leakage due to a large crack repair in the main pool, and thankfully found no losses in the main pool.
In the hot tub, I've tested with pump on and pump off for 24 hrs. Both times I drained it down below spillover height, and I've isolated the hot tub plumbing to recirculate for the pump on test.
Pump off: Outside of bucket lost 1.3" while inside lost 0.5".
Pump on: Outside of bucket lost 0.6" while inside lost 0.5".
Contractor will be coming in the morning, but wanted to see if this points to any specific type of leak?
Did some more reading.. seems to indicate suction side loss, pointing perhaps to drain modification. Will try to find with food coloring.
