been a busy day
learned that at the lake house the well is at the top of the hill so it siphons down to the house and never stops flowing. Also discovered they used the incorrect fittings into the plastic well pipe. Third time was the charm and no more leaks at the main shutoff valve.
Flooded the crawlspace and got to wallow in the mud.
Now just need to try again on the kitchen sink sprayer leaking. Wish someone would standardize crap.
