I’m sure you’ve never heard this one before. I was leaning over my open toilet tank trying to adjust it to stop it from running as I’ve done many times before, when my head bumped the little shelf on the wall over the tank. My 4.5 inch statue of the Virgin Mary toppled off the shelf, into the tank, and down into the pipe that the ball plunger sits in! In a flash, she was gone, and potentially in a position to clog my toilet and/or sewer drain. Advocate came within hours, creatively tried several things and was able to retrieve her without damage. Then they got my 97 year old toilet (best one in the house!) up and working again. Thank you, Advocate! 🙌🏼🙌🏼

We had a great experience with Advocate Plumbing. They did a fantastic job from start to finish. Brian came in and inspected the problem with the water heater. He also tested the water and found out that our water softener stopped working and need a new replacement. After the inspection, they gave us a couple of options with all the steps needed in the process. With high quality products and installation for a reasonable price and exceptional service, I highly recommended Advocate Plumbing for your next plumbing services.

Had Brian come out to install a water softener and remove my old one. He was very professional and on time. He told me everything I needed to know. Was very honest and did not try to oversell me. I felt he was genuine. Checked my water pressure for free to make sure everything was going to work. Beat previous quote for same job by couple hundred dollars. Will definitely be using them again for my plumbing needs.

Advocate Plumbing replaced my broken sump pump and did an excellent job in doing so. Dylan arrived earlier than was scheduled which worked to my advantage. He patiently answered and explained things I do not understand. He even checked my water PSI and the water coming out of my water softener - something that was never done by the past plumbers who serviced my house. His work was efficient, clean and thorough. Overall, I highly recommend Advocate Plumbing!

Dylan was our plumber. He answered many general questions regarding our plumbing system, gave us a number of recommendations, installed a new water heater to replace our 9 year old tank, hooked up a gas line, and took great care of our carpet, etc Dylan was knowledgeable, friendly, helpful, and a joy to do business with.

We recently had a water softener installed, and the entire experience with Advocate Plumbing was outstanding. From start to finish, the professionalism was clear. They arrived on time, communicated every step of the process, and made sure we understood how the system worked before they left.

The installation itself was clean, efficient, and clearly done with care. They treated our home respectfully, kept the workspace tidy, and double checked everything to ensure the system was running perfectly. It’s rare to find a company who combines skill, courtesy, and genuine pride in their work—Brian and Vance absolutely did.

Our water softener is working beautifully, and the whole experience was smooth and stress free. We highly recommend Advocate Plumbing to anyone looking for quality plumbing work and true professionalism.

p.s. They also flushed out our hot water tank while they were here…and checked all of our plumbing fittings throughout our home.

They did a fantastic job...in most cases without me being there. I had wanted a tankless water softener. I am very glad I reached out to these experts as I saved having to replace a tankless because it would not be sufficient to treat minerals, etc., in my area. I also have a duo system that better filters my shower and tap water as well.

Outstanding response, we had water all over our utility room now that there really wasn’t a problem. It was an overflow deal with clogged inspected everything and no charge. Can’t beat that.
