Tankless water heaters need annual maintenance — especially in Redlands where hard Inland Empire water deposits mineral scale inside the heat exchanger at an accelerated rate. Neglecting descaling cuts efficiency, triggers error codes, and shortens the unit's life. Redlands Heights Plumbing Pros performs descaling, inlet filter cleaning, flow sensor checks, and full system inspection to keep your unit running like it should. Upfront pricing. Licensed & Insured.
Signs You Need This
- It has been more than a year since your last tankless service
- Hot water output seems reduced compared to when the unit was new
- The unit runs longer before reaching temperature than it used to
- An error code appears occasionally then clears itself
- Hard water scale is visible at connections near the unit
- You live in Redlands Heights and your unit has never been descaled
Common Causes
- Hard Inland Empire water depositing calcium and magnesium inside the heat exchanger
- Clogged inlet filter screen restricting flow and stressing the pump
- Scale accumulation on the heat exchanger fins reducing heat transfer efficiency
- Sediment in the cold-water inlet filter reducing pressure to the unit
- Licensed & Insured (CA C-36)
- Local & Family-Run
- Workmanship Warranty
How We Work
Our Tankless Water Heater Maintenance Process
- 1
Inlet filter inspection and cleaning
We remove and clean the inlet filter screen. A clogged filter restricts flow and causes the unit to underperform or trigger low-flow shutoffs.
- 2
Descaling the heat exchanger
We flush a food-safe descaling solution through the heat exchanger using a circulation pump. This dissolves mineral scale buildup — the main maintenance job for tankless units in hard-water areas.
- 3
Check the venting and air intake
Blocked venting causes gas unit shutdowns and potential safety issues. We verify the vent path is clear and unobstructed.
- 4
Inspect components and error history
We review any stored error codes, inspect the igniter, flow sensor, and connections, and note anything that shows early wear.
- 5
Document and advise
We give you a summary of the service and any items to watch. If anything needs attention before the next annual service, we'll tell you now.

What Customers Say
Trusted for tankless water heater maintenance across Redlands
“Got three quotes for a new water heater. They were the only ones who explained tank vs. tankless without the hard sell, gave a clear price, and installed it the next morning.”
“Our water heater quit on a Sunday morning. They walked me through repair vs. replacement, gave me an upfront price, and installed a new unit the same day. Honest and easy to work with.”
“Called at 11 p.m. with a burst pipe in our older Redlands Heights home. A plumber was here fast, showed me the problem on camera, and had it fixed that night. No surprises on the price.”
Frequently Asked Questions
Common questions about tankless water heater maintenance in the Redlands area.
How often should I descale my tankless water heater in Redlands?
Once a year is the standard recommendation. Redlands hard water means we'd lean toward not stretching that interval — some units in very hard water benefit from every 6 months.
Can I descale my tankless heater myself?
The process requires specific equipment — a submersible pump, descaling solution, and hoses to recirculate through the heat exchanger ports. Some homeowners do it themselves; we do it for you as part of a full maintenance check.
Will descaling fix my error code?
Scale-related error codes often clear after descaling. If the code persists after service, we dig further — it may indicate a different component failure.
My tankless unit is only 2 years old. Does it already need service?
In Redlands, yes. Hard water doesn't give your unit a break just because it's new. Annual service from installation day is the right approach here.
Does regular maintenance actually extend the unit's life?
Meaningfully so. Scale accumulation forces the unit to run hotter and work harder. Removing it regularly reduces stress on the heat exchanger — the most expensive component to replace.
