1-2 gpm zone leak (when turned on), cant find.
Cant find a leak...
How do i find it?
Large low laying deck, underside too low for crawl.
A drain tile will flow the leak after a few minutes of run.
Cant hear the sounds of flowing water from anywhere, Execpt the drain tile exit.
Supposedly the drain tile is under the house...
House addition, but reportedly piped around after construction.
