I've been a customer in the past and my better half has as well. It's not an easy task when there's a leak but it finally got fixed .
On our property there's been a leak , it's a mess without a water key to repair it in the yard which isn't the case inside usually. Typically the best turn off possible is under the sink . I can do it under the kitchen or each bathroom, behind the toilet is good. The water heater is right at the source usually. There's a few tasks that need a key in the yard to get a plumber. The neighbors got it fixed fast . We've browsed around , called a couple before reporting a leak to the company. I reports leaks , outages and down wires big or small. Some problems you can't easily see . The job was finished . The plumber was not happy with the pvc or plastic pipe connecting to the brass one . He prefers the brass . It was caught and completed. Thank God.
Recommendation: Report all leaks if you suspect that it may cause problems with the neighborhood or public health and safety .
