Best Plumbing Inspection in San Francisco CA

Called Norman Saturday morning to see if we can get help with a sprinkler that won't shut off.  He was kind enough to talk us through potential problem areas over the phone.   We ultimately figured out how to shut off the sprinkler.   We asked if how much we would owe him for the phone consultation and he refused.  We'll be using him next time we come across any house work required or issues.
