"We were so fortunate to find American Plumbing and Sewer, LLC! We had a quote from someone selling water softeners for $12,000, and we thought, â there has to be another much less expensive option out there!â With Lannyâ s company we got a system of much higher quality that cost 1/4 of the other personâ s quote. Personable, reliable, honest and wonderful customer service are words that describe American Plumbing and Sewer."

"Pure Water beat the other contractors on price and what we received as a product. We couldn't be happier with the installation. We now have hot water on demand on the opposite side of the house where it could take 5 min of water running for the water to be hot. Pure Water also installed a water softener and now our hard water is soft! Patrick who did the install was professional, personable, picked up what little mess there was, explained everything once the install was complete. We are so pleased we have them on the hook for a fireplace gas line and will have several bathroom projects going forward. We could not recommend Pure Water Services more. Thank you"

"I would highly recommend this company! My service pro was knowledgeable, friendly, and efficient! He took on an old, leaking, rusted water heater job that was not for the faint hearted. He problem solved every odd glitch that my older house threw at him. The whole experience was completely positive!"

"Excellent...we had some additional issues related to water pressure regulator, piping, etc. The situation happened on the weekend and we had hot water running by Monday afternoon. An EXTREMELY short time compared to our last water heater issue. Highly recommend Heart and will use them from now on."
