I was nervous at first, but the Advocate Plumbing team was incredibly efficient, reliable and honest. They arrived exactly on time, quickly identified a leak detection problem and fixed it with clear knowledge and professionalism. Their punctual service and straightforward communication made the whole experience stress‑free. I would definitely call them again for any plumbing needs.

We reached out to Advocate after receiving some unexpectedly large estimates from a bigger plumbing company. Advocate came out to estimate and gave us a home inspection while they were here. Their estimates were much more in line with what we expected based on our research. They were able to get us scheduled very quickly and did an excellent job while they were here. We had quite a few things to be done, so Zach was at the house for a few days in a row. He was exceptionally friendly and professional, and ensured we were happy with all of the work that they did each day. He was able to help us troubleshoot some more tricky issues which we really appreciated. We really liked how in the loop we were kept throughout the whole process. We 100% recommend Advocate (and Zach) to anyone looking for plumbing work to be done! We will be using them going forward for all of our plumbing needs. EDIT: Adding in that Jeremy (the owner) also came out one of the days to help take on some of the work we needed done. He was also a pleasure to work with!

I had a pre-sales inspection done where some plumbing items were called out as being in need of repair, and I contacted Advocate for a quote. Not only did they come out quickly, they got me sorted out on the same day after giving me a super reasonable price! Highly recommend!

My wife and I needed to have an additional hose bib installed but wasn't sure how to run the water line without causing major remodeling issues. Jeremy and Dylan came out to assess the issue. We arrived at a solution and much to my surprise, they not only quoted the job but also did the work the same day. It was a tricky installation but Dylan did a great job! ---------------------- Having had a good first experience with Advocate Plumbing, I called them again to flush out my tankless water heater and install a new sump pump with a battery backup pump. Both jobs were done promptly and professionally for a reasonable price. We can now leave home with the peace of mind we have a good quality sump pump and battery backup sump pump that replaced an inexpensive builder's grade sump pump. This company is very fast at scheduling the work. I've had three different plumbers do work at my house and all have been great to work with. And the owner Jeremy is a great guy!

If you have any plumbing problem in the central Indiana area, you may benefit from my experience with Advocate Plumbing. In just a single call, I connected with the Owner, their Service Manager and ultimately the Service Technician who completed a huge job in one day: a sewage sump, foundation sump, battery install and two fixtures. Same day response…all jobs completed…and to my complete satisfaction! There is no reason to chase the big companies with huge call centers…Advocate Plumbing was fast to arrive, thorough in their work and friendly as you would hope. Give them a call first, you will not be disappointed.

We had a gas leak and initially had another larger company out for diagnostics. We weren’t happy with their pricing or lack of scheduling availability for repair so I decided to get some other quotes. I was recommended to Advocate by our home inspector and I’m really glad I gave them a call. Steve helped me to get a plumber out ASAP and was very competitive with pricing. Zach was able to complete our repair and get our gas turned back on in just a few hours. He was knowledgeable, easy to communicate with, and I appreciated that there was no sales pitches or trying to upsell on services we didn’t need. We were even able to talk to him about some plumbing needs at our new house we’re moving to at the end of the month including our sewer lines needing hydrojetting and were quoted a fraction of the cost that two other local companies quoted us. Great customer service and we will be return customers!

Jeremy and Dillon reviewed the options and then efficiently installed a new outside hose bib at our home. They were conscientious about our home and thoroughly cleaned up the work area, as well as confirmed we were totally pleased with the work performed. Will definitely call Advocate Plumbing the next time we need plumbing work completed. Update - July, 2025. Contacted Advocate Plumbing to flush our 5 year old tankless water heater. While discussing this service with our technician (Brian), we also mentioned that we were considering a battery back-up sump pump. We received a call from Steve (Customer Service) who quoted several options. After reviewing the options/costs, we agreed upon one and were assured that the work could be completed that day (they had confirmed that necessary parts could be obtained.) Brian went right to work on this unexpected (much larger) job and worked diligently until the work was completed and totally checked out. We appreciate the professionalism and expertise of the team at Advocate Plumbing.
