Damn, I hate old houses.
So I have a patch of wet concrete slab in my garage that's very slowly getting bigger. Plumber came out, did the meter test (watching the spinner on the water meter with everything in the house shut off), even put a pressure valve on my system and turned off the water at the meter, watching for a while to see if the pressure would drop from a leak. Plumber says no supply line leak.
Now of course he was only there 30 min, so for eight hours today I had all my inside water turned off (incuding supply lines to the toilets) and for 7 hours the water meter sweep hand didn't budge at all.. but in the last hour it ticked up 1/10th of a gallon.
So my question is, do sweep hands on water meters move in an analog fashion or do they just suddenly click over the next 1/10th of a gallon?
