I called Advocate Plumbing when our hot water heater went out. It had ended up cracking and leaking onto the floor because there was a plastic catch pan underneath that had melted. They were very knowledgeable and told me my options for a new water heater that would work for my home. They were able to get us scheduled the next morning and arrived on time and were very professional. They prepared the work area by putting down paper to avoid any mess while getting the old water heater out and to avoid scratching our floor. They installed an aluminum catch pan so we shouldn’t have to worry about any water damage in the future. Our utility room was definitely cleaner after they left. While turning off the water they noticed some potentially unsafe fitting on our shut off valve and were able to quickly replace those as well. We had a great experience with Advocate Plumbing and you will too.

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.

Had some gas lines run and Dylan did an excellent job. Jeremy returned initial referral contact call quickly and was very friendly and responsive. Dylan was on time, efficient and professional. Service pricing was excellent and we were extremely pleased with Advocate Plumbing and would highly recommend the company! Had a shower leak repair done a year later and again received excellent customer care and service.

We recently engaged Advocate Plumbing Company to complete the rough-in plumbing for our new master bathroom shower. From the initial consultation to the final cleanup, the entire process was seamless. Zach R. was prompt, courteous, and demonstrated exceptional craftsmanship. He took the time to walk us through the work and ensured everything was perfectly up to code. A truly professional and reliable service—we couldn’t be happier with the result and would highly recommend Advocate Plumbing to anyone for all of their plumbing needs.
