Orange County's hard water quietly destroys tankless water heaters from the inside. Annual flushing removes mineral buildup, restores efficiency, and keeps your warranty intact.
Orange County's hard water is among the toughest in the nation. Here's what's happening inside your system right now — and what a flush does about it.
Hard water minerals (calcium, magnesium) accumulate inside the heat exchanger, creating a thick layer of scale that gets worse every year.
A professional descaling flush clears the buildup before it causes damage — restoring performance and protecting your investment year after year.
Every photo is from an actual service call. This is what hard water does to an unflushed tankless system.
Industry data on what regular maintenance does for your system.
Navien, Rinnai, and other manufacturers require annual flushing to keep your warranty valid. Scale-related claims are denied without proof of maintenance.
If your water isn't as hot as it used to be, scale is likely the cause. A flush can restore your temperature to day-one levels without replacing the unit.
Regular flushing can extend the lifespan of your tankless water heater by up to 20 years — compared to 8–12 years without maintenance.
Scale buildup is the leading cause of heat exchanger failure — a $1,500+ repair. A $200 annual flush is one of the best investments in your home.
With 15+ years in construction and home renovation, I understand how homes work and what matters to homeowners. Tankless water heater maintenance isn't a sideline — it's a core specialty I've invested in deeply.
I specialize in diagnosing and maintaining tankless systems across Irvine's neighborhoods — including Woodbury, Orchard Hills, Great Park, and Northwood — as well as Newport Beach, Newport Coast, Corona del Mar, and surrounding areas.
When I show up, you get me — not a dispatcher or crew. I do the work personally, explain what I'm finding, and answer all your questions.
A complete service visit takes about 1–1.5 hours. Here's what you can expect.
I assess your system, check the inlet filter, and identify the degree of mineral buildup before starting.
Using professional equipment and descaling solution, I flush the heat exchanger to dissolve and remove mineral deposits.
I clean the inlet filter, flush supply lines, and ensure water flows freely through every part of your system.
I confirm proper operation, water pressure, and heating function — then show you before and after photos of the flush.

Dustin was prompt, friendly, helpful, answered all my questions and even researched stuff for me. He serviced the tankless water heater and was great!
We had Dustin come to our house & gave our tankless water heater a check up & flushed the system. We kept his information to have him come back when it's needed again. Very reasonably priced too!

Dustin replaced 5 faucets for me, changed out a thermostat, and flushed our tankless water heater. He did a great job, was professional, gave me a great price, and I will definitely hire him again in the future!
As a Realtor I know how important (and how difficult) it is to find an outstanding handyman, and Dustin is among the best I've worked with. Knowledgeable, proactive, punctual, trustworthy… His workmanship, work ethic, and professionalism are excellent.
Everybody NEEDS to use this handyman. I was just amazed at how professional, efficient, and pleasant Dustin is. His estimates came in significantly lower than those I received from others. Multi-talented and I've already asked him for quotes on other projects.
Dustin was extremely responsive to my messages and questions. He was able to finish installing a faucet, complete my painting, replace the bathroom fans and also swap out door knobs in good time. I appreciated his before/after pictures. I would highly recommend him!
Dustin was knowledgeable, professional and friendly. He worked with my schedule and kept me informed via texts of when he would arrive and his progress on the work being done. Reasonable rates and great work!
