i got another estimate on water heater and pipes he must reroute and valves that need replacing. $3000.00.
most of that is labor. water heaters I saw were $300 to $500 and the regulator valve he quoted $600.00 for can be purchased in a plumbing shop for $57.00!!
i may call another plumber to fix the "now leaking" shut off valve and needed by code regulator and see what price they quote me. i hate leaving plumbers alone in my house because before they leave, something is always leaking that wasn't when they arrived!!!
and yes, i'm going to Lowe's for a water heater!
