From the first phone call Jeremy was really kind! Zach came out and did a wonderful job installing a new water softener, regulating our water pressure, replacing our hose spigot, and flushing our water heater. He was kind, respectful of our home, and explained everything well. After many bad experiences with other plumbing companies, I can truly say I’ll call Advocate first.

We were looking for a locally-owned plumber with reasonable pricing for a sump pump replacement and main water shut off repair. We found this with Advocate Plumbing - Jeremy was extremely helpful and knowledgeable on the phone and got us scheduled quickly. Brian was our technician and he was respectful, efficient and competent. He identified a few other issues in the house and we were provided with some additional options without any pressure. We are extremely pleased with their plumbing services and will use them again.

If I could give them 10 stars, I would! Hands down the best service and price in the area. At first, I was a little concerned when they sent over a professional estimate with photos—but as soon as I saw the price, I committed on the spot. They did amazing work.

Advocate Plumbing replaced our failing tank water heater for a tankless water heater. My Father had a great experience with Advocate when his water heater failed just 2 weeks prior to mine and immediately referred them to me. The communication and professionalism of both Tyler and Dylan was fantastic. Straight forward, honest, and no forced / unnecessary upsells. Good pricing for the work done and product provided. On top of that, Dylan left the work area better than he found it which I appreciated. Was a great experience working with a local company that provides, great work, communication, honesty and outstanding professionalism. Can't recommend them highly enough. Update 4/24/2025: Upon arriving home from vacation, our sump pump system failed and we returned to a flooded basement. We called Advocate Plumbing to come out and replace the Sump pump and back up battery system as they were inoperable. Tyler provided a great price for the replacement and Dylan came to our house within in a couple of hours to repair / replace the failed system. As always, Dylan did a fantastic job considering he was working in water. Can't say enough about the folks at Advocate. Great people, fair prices, and quick response to our emergency.
