Questions

Water line replacement, answered.

Answers from licensed plumbers. Still unsure? Call (509) 535-5946, 24 hours a day.

Can a water line be replaced without digging up the yard?
Often, yes. Where the soil, the length of run and the old pipe allow, we work from small access pits at each end instead of a trench. Rock, sharp bends or a badly crushed line can rule it out, and we tell you plainly which yours is.
How much does water line replacement cost?
It is priced on site after a free written estimate, because length, depth, soil and what has to be crossed all change the work. Other lines on the estimate come from our flat-rate book, such as a main shut-off valve from $555 and the city water permit at $230.
Who is responsible for the water service line, me or the city?
In most places the property owner is responsible from the curb stop or property line to the house, and the city maintains the main in the street. The exact boundary varies, so a call to your water purveyor confirms it.
Why do water lines fail around Spokane?
Age and material first: old galvanized and undersized copper corrode from the inside. Roots, settling ground and Inland Northwest freeze-thaw cycles on shallow runs do the rest.
Can I finance a water line replacement?
Yes. You can pay over time with the Wells Fargo Home Projects credit card and its special promotional offers where available. Credit is subject to approval.
