The latest..................... I've slowly put water into the tub and measured it on the jets. It was not leaking and I'd made it half way full - then I wondered if it could leak because there was air in the lines. I quickly ran the pump, and saw exactly where the water level was. This morning it is down about 1 inch. So is it one of the jets I'd just covered or a connection that is leaking after I'd ran the pump? I'm calling the repair guy again, hopefully we won't wait 3 days for a return call.
