Last couple days have noticed wet spot near a decking drain. Been raining a bit, so didn't think much of it. Went out today in sunshine, area was dry. Ran the circ pump, water appeared, so apparent leak on pressure line to pool. Worried about water damage, can I leave the circ pump off for a few days until I can cut the concrete and fix the leak? Weather has been rainly and cold for San Diego area, highs in 50s, lows in 40s.
