We would give more stars if we could. We had an emergency on a Sunday morning and Dave was AMAZING! He answered the phone right away and was able to fix the problem that morning. He was kind and helpful and ended up saving us money! We highly recommend National Water Service. An easy FIVE STARS.

We lost our water on Sunday and could not reach our regular plumber. My initial contact with Dave was met with an eagerness to help try and restore our water ASAP. He guided me through some procedures to attempt a “reset” over the phone (all done without getting $$ upfront). They arrived Monday with the pump and controller but took the time to troubleshoot and diagnose the root cause (rather then just replace the pump and controller). National Water Service will be our first call whenever we have a plumbing need in the future.
