"I found Ralph on Angie's list and contracted him for a clogged drain. I was pleased that he responded quickly and he took care of 2 clogged shower drains. The following week, my hot water heater broke and Ralph called back five minutes after I sent him a text. He replaced it with a superior model (which cost only a little more than the cheap model that I had and he explained the features which made it superior. I later found a YouTube video which confirmed everything that he said). The warranty was better also. He came back the following day to replace two toilets which had been causing leaks in my kitchen ceiling. I'm very happy with my new water efficient toilets which flush with more force than the previous ones, and, no more leaks! While Ralph was replacing my water heater, he noted problems with the installation of my 35 year old boiler and pointed out issues that a more modern and energy efficient boiler would address. There was no hard sell, just a matter of fact recommendation that I might consider replacing it before next winter. I've been hiring contractors for the past 22 years, and I'm impressed by Ralph's knowledge, experience and professionalism. If you call for service, you will get Ralph himself, not a random plumber that a larger company will send. I've already booked Ralph again for my broken sump pump!"

"Kyle and Justin installed a new 75 gallon water heater in my home this past week. The job was extensive due to need to remove incorrect pvc piping then install proper grade pvc to meet code. In addition they replaced and re install rigid piping for gas lines that apparently builder had not done correctly (shorts cuts!) this was also verified by another plumbing contractor of which we brought in for an estimate. So glad we went with Water Mac to do the job. Kyle and Justin's work was outstanding! These guys are nice, honest ,competent and fairly priced. I highly recommend them. Tammy Schoffelen"

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"Excellent customer service. My Hot water heater busted on Christmas night and i called advanced professional 26th early morning, tech at my home in no time to provide estimate and work was done within next 4-6 hours. Technician name Abe who came to my house for service is one of the best. Very polite, professional and make sure work is done neat and clean. Only one thing i am not happy is i think it was little pricey but since it was urgent service i can't complain."

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."
