"Alec from Aqua Sewer & Drain Service very professional when he showed up to check the water leak we had. Alec diagnosed the issue and said we needed an expansion tank since it cracked and that’s where all the water was leaking from. He said we don’t need a water heater because that is functioning properly. He took some pictures and then went to get the parts and came back within 30 mins and started the work. You can tell he really knew what he was doing. He had all the right tools in his work truck. He removed the old expansion tank and put in the new expansion tank and a shut off valve and he also strapped the expansion tank so it got added support. He also check the water pressure and looked for leaks before he left. We had this issue Friday night around 11pm and we call his company Saturday morning and he should up at 8am. It took about 2 hours before he finished. Alec was very knowledgeable, he also wore booties on his shoes in our house. I would recommend Aqua Sewer & Drain Services to anyone who has any plumbing issues. We live in South Brunswick NJ."

"Chris corrected and water heating problem which was misdiagnosed by a tech from NJR home services. Their tech (NJR) never actually worked and in hindsight looks to me was only trying to get me to buy a new heating unit. Thank you Chris Walton for a great job."

Customers say: True professional

"We had several different technicians working on installing a new water heater in a crawl space. There were several different unexpected occurrences that arose, but the guys were great. They were respectful, curious, helpful, understanding, knowledgeable and extremely patient explaining our oppositions. They were responsive and prompt to some unexpected situations. Highly recommend them, I'm giving the technicians ten stars for their professional and respectful work ethics."
