Plumbing in Rancho Mission Viejo, CA
24 hour plumbing for Rancho Mission Viejo homes and businesses. Family owned since 2013.
Serving Rancho Mission Viejo and Surrounding Areas
Most homes on the Ranch run tankless water heaters, and tankless units in hard water country need regular descaling service to keep their efficiency and their warranty. That maintenance visit is one of our most common calls in Sendero and Esencia. Whole house filtration and water conditioning are close behind, because South Orange County water is hard enough to spot every glass and scale every fixture in a new home within months. Outdoor living is a big part of life out here, so we run and repair gas lines for barbecue islands, fire pits, and patio heaters. And even new homes clog drains, especially kitchen lines that see daily cooking. What we do not do is invent problems. A new home rarely needs a repipe or a sewer replacement, and we will tell you so. When something real goes wrong at midnight, a burst supply line or a failed water heater, we answer the phone and come out. Hummel Plumbing has served this corner of the county since 2013, holding CA license 1034213.

Jon was personable and knew exactly what to do to pull a new waterline for our refrigerator up from our crawl space. He was also very informative about differing water pressure throughout our house. It was obvious he took pride in his work. Communication from Sally was excellent. Stellar family team in the neighborhood. Nice to know we can trust them for our plumbing needs.

Jon always does an amazing job! We've used his services for years. He's on time, his prices are fair and his work is reliable. We needed a full house repipe after a pipe burst. I knew exactly who I would call for this big job and who I could trust-Hummel plumbing!

As a retired plumbing contractor, I'd like to think that I can tell a good plumber, hard worker, and honest man after watching him work. I'm getting a little long in the tooth (and sore in the back) to do much of my own plumbing anymore and I call Jon when I need plumbing help. I have also referred him to my neighbors, who report that they have been very happy with him.

We've used Jon with Hummel Plumbing a few times now here in San Clemente, and he's been great every single time. He previously installed our tankless water heater, and most recently fixed our outdoor shower and handled a few other items for us. Everything has always been done correctly the first time—no shortcuts. He's friendly, thorough, and clearly takes pride in doing things the right way. He was also able to come out quickly, which we really appreciated. It's honestly such a relief to have a plumber we trust. Highly recommend Jon and Hummel Plumbing!
