Restore Your Endless Hot Water & Protect Your Investment
Get a professional tankless water heater flush & descaling service for just $449 flat-rate, truly all-inclusive with zero service fees and zero hidden charges.
Don’t Let Hard Water Minerals Kill Your Tankless Unit
Tankless water heaters are incredibly efficient, but they have a major enemy: hard water scale. Over time, calcium and lime build up inside the narrow copper heating tubes of your heat exchanger.
When scale forms, it creates an insulating barrier that forces your unit to burn more gas or electricity just to heat your water. If left unserviced, this mineral scale causes the system to overheat, throw error codes, lose water pressure, and ultimately suffer catastrophic component failure.
Our $449 Tankless Flush & Descaling Service safely strips away this harmful buildup, lowers your energy bills, and protects your manufacturer's warranty.
What’s Included in This Deal?
A Comprehensive, Factory-Grade Maintenance Service
When we say all-inclusive, we mean it. Our flat-rate tankless service features:
Deep System Descaling: We hook up a specialized commercial pumping system to circulate a non-toxic, professional-grade descaling solution through your unit for a full cycle to safely dissolve internal lime and scale.
Intake Filter & Water Strainer Flush: We pull, clean, and flush the internal water line strainers and debris filters to restore optimal system water pressure.
Flow Sensor Alignment & Cleaning: Cleaning the critical sensor that detects water movement, preventing random cold-water drops or temperature fluctuations.
Component Safety & Performance Checklist: Full diagnostics on your electronic ignition system, flame rods, and air intake/exhaust venting to guarantee safe operational compliance.
ABSOLUTELY NO HIDDEN FEES: The price we quote is the price you pay. You will never see an added trip charge, diagnostic fee, or environmental fee added to your bill.
Why Choose NB Plumbing?
Transparent Pricing. Professional Craftsmanship.
Upfront All-Inclusive Pricing: Most plumbers use low bait prices and then stack on "trip charges" or "tool fees." At NB Plumbing, we believe in complete transparency.
Certified Technicians: Tankless water heaters are complex electronic systems. Our background-checked, fully insured professionals are specially trained to service all major tankless brands.
100% Satisfaction Guarantee: We treat your home like our own. If your service isn't performed to your exact standards, we will make it right, guaranteed.
Experiencing Error Codes or No Hot Water Right Now?
If your tankless system has already shut down or is displaying an active error code, it may require a physical repair or component replacement rather than a standard maintenance flush. Don't worry, our technicians carry a full array of diagnostic tools. Skip the form and call us directly for quick, honest troubleshooting and upfront repair pricing.
Terms & Conditions: Flat-rate offer applies to single-family residential tankless water heater units only. Commercial systems, manifolded multi-unit systems, and traditional tank heaters are excluded. System must be fully operational and possess standard, accessible service isolation valves (hot and cold flush valves). If isolation valves are missing or frozen, our technician can provide an upfront estimate to install/replace them before the descaling service can safely proceed. Cannot be combined with any other offers or volume discounts.
