Last Wednesday, €Ž3:30 AM, Becca wakes me up to say that the laminate
floor in the bathroom is "squishy". Remove bathroom door, remove linen
cabinet to get at wall behind shower... find leak, clean up, go back to
bed. Called the plumber at 7 AM and he was there by 10 AM.

€ŽThe culprit was a 30 year old copper pipe feed line.... corroded and
split at a joint. I am not good at sweating copper joints... but I got
the wall opened and clear so the plumber had easy access so it took him
less than an hour. I got everything back together and only have to re-do
some trim work (baseboards and 1/4 round)

A pox on builders who bury copper piping inside walls without leaving
access panels.
