Our Water Heater Installation Process
We begin by assessing the property, its existing equipment, and expected usage. This allows us to size the new system according to demand rather than automatically matching the old unit’s capacity.
Your installation can include:
- System assessment: We review daily demand, available installation space, and the property’s fuel or electrical setup.
- Free estimate: We provide upfront pricing so you can review the proposed work before installation begins.
- Code-compliant installation: We address thermal expansion tanks, proper drainage, and gas sediment traps when applicable.
- Old-unit removal: We remove and dispose of the previous water heater.
- Final testing: We check gas pressure where applicable, water flow, and temperature settings before completing the work.
A standard storage-tank replacement is typically completed within three to five hours. A tankless conversion can take longer if it requires gas-line or venting updates. After evaluating the installation conditions, we’ll explain the anticipated scope and timing.

“What an amazing day, who can say that after a water heater breakdown? We called, and you guys didn't let us down. 20 minutes after our call, the service repair men were joyfully, professionally ready at my door. They examined, explored, determined what happened to our 3 year old Water heater, found our house regulator valve shot, corrosion was filling the diaphragm of it, preventing it from regulating our water pressure. Because our water pressure was over 100 psi, our 3-year-old water heater inner liner was torn through, and the entire tank was emptying around the lower seam. Everything was shown, explained, and once they learned that my husband is 100%disabled vet, and currently recovering from shoulder surgery. The discounted price met our ability, and 2 hours later, we have a new water heater and water regulator, and are happy that this company met our needs.”Pamela T.

“We had an issue with the plumbing in our master bathroom develop over the weekend. This had a sudden onset and very odd pattern. On Monday AM we called Scott McLeod Plumbing and to my surprise, they were able to send out a team a few hours later. Based on our description of what was happening, and his inspection of a few things, Teddy deduced immediately what the most likely problem was and explained to us the sequence of events that caused our problem. It was so logical and was communicated to us so clearly that we immediately felt complete trust in the solution he proposed. He was very obviously a complete expert. The cost proposal for all the work was very reasonable. He and his assistant spent the rest of the day solving our problems. It was such a pleasure having two such lovely people take care of our issues. I have used another top-rated local plumbing company in the past and although they did good work, I felt like their pricing was very high.”Happy Customer

“Scott McLeod Plumbing showed up in my time of need and truly saved the day. They were helpful, reassuring, and professional during a very challenging situation. I had previously worked with another plumbing company that left me uncomfortable with some questionable accounting practices, but Scott McLeod Plumbing completely restored my faith in both honest and quality service. From start to finish, everyone who worked on our project—Teddy, Peter, and Michael—was pleasant, professional, and respectful of our home, including our landscaping. They completed the job quickly, which was especially important since it was a time-sensitive repair, and their attention to detail and care were exceptional. I am so grateful for their expertise and kindness. Thank you, Scott McLeod Plumbing, for turning a stressful experience into a positive one.”Vera N.

“Glad I reached out to these guys when a family friend needed help with plumbing issues that had them shutting off their water and heating water just to shower. These guys were prompt and thorough, and about $1K cheaper than another local shop (not naming names, but shame on you, we thought you’d be better). Funny enough, this company is also family-owned, just more modernized and organized, which is a huge plus!”Monica G.
