Unusual Water Pressure Drops: Sudden changes in water pressure may suggest backflow issues or valve failure.

A total A+ experience from start to finish! I own a house with two aging water heaters and decided to replace them with a tankless system. From my initial contact to the installation everything was beyond what I expected. Gaige and his assistant Skyler did a great job even after being faced with the unexpected challenge of having to add an additional hot water line. It's rare to have a service-related experience that exceeds expectations and this was definitely one!

We just had a new stove installed in our home which was built in 1926. With all old houses, there are always multiple surprises, layers of useless, outdated connections and weird shenanigans. Eric masterfully reengineered the attachment set ups and managed to get the stove installed. While we had to spend more than we originally bargained for, he knew what he was doing and did it well. He is personable and a good communicator.

Keenan was professional and kind in both his work and demeanor. He answered questions and explained any part of the process we had questions about. Although, we had a delay both Keenan and his apprentice Skyler once work began were on point and made great time finishing the job in one day. We were very pleased with the end result and felt confident in the work. We can't thank them enough.

Alec R. was a great help during our flooring installation. He arrived promptly and removed and reinstalled our toilets and gas stove, and was flexible and efficient in working with our installers. He also identified a problem with our water pressure, and installed a pressure regulator valve to lower the pressure to a safer range. We highly recommend Olympic Plumbing Technology and plan to use them again for our future plumbing needs.
