We have a small drip leak at the base of our heater. Not a constant run, but a steady drip. Last night at around 5:00 I marked the water level and this morning at 8:30, the level had dropped to just under an 1/2". Could a small drip cause this much loss? Luckily my heater is under warranty and the repair man is scheduled to come, but this seems like too much. This is our first pool, it was installed last summer. It is a 12x25 fiberglass pool and our temps have only been in the upper 70's. If this is not the heater, how does the PB even find a leak? We've checked all around the pool and cannot find any sign of saturation and the dry well is not full.
