"They replaced my tankless water heater, under sink valves with quarter turn ball valves and three toilets. The price was fair, a little high, but the quality of work and service was excellent. These plumbers know what they are doing. They were timely and had good communication."

"Needed to replace hot water heater and mentioned that when the service call was made and asked that they come to the house with the replacement. They came to do an estimate and wasted three hours after I approved the estimate as he had to go pick up the water heater."

"Such great service!! My water heater went out in my rental property and they were able to hop on the phone with me right away and offer me a quote. Within the next 2 hours someone was at the property - they removed the old water heater and installed a brand new one and were on there way. Cobra Rooter & Plumbing was professional and quick! Will use again in the future."

"I was highly impressed with the advice I received from Glenn, which I was advised to get with the home builder first to find out the specific cause of the problem with our tankless water heater, and then proceed from there to decide the action to take, if more additional work is required."

"Two valves and a leak were repaired. I started with old rusted main that was leaking. While doing the work I asked to have the hose bib updated and the system sprung a leak that was also repaired. Daniel Medina was awesome. He was friendly, courteous, fast thorough and did a great job. I was so impressed!. Prices seemed a bit high but Daniel did such a great job I barely noticed the sting. Thanks Daniel and thanks Tucker Hill for getting to me in a 'no water in the house' situation, to fully operational with a potential future issue handled in under three hours. That is three hours from the call to Tucker Hill asking for help to thanking Daniel as he drove away, problem solved. Shoot, I'm happy."

"I would highly recommend HMU Water Service. The owner, Noah is so meticulous with his work. His pricing beats anyone out there for quality service. We have had an RO system, a whole house purification system, water softener and tankless water heater all installed or repaired/serviced by him. I am happy to recommend this company to everyone I know."
