Frequently Asked Questions
How Much does it Cost?
$110. most other servicers charge upwards of $150-$300 per flush. No added tax. No additional charge for indoors.
How often should I flush my tankless water heater?
Most manufacturers recommend once per year. Homes with hard water may benefit from more frequent service.
Do I need to be home during the service?
Not if your unit is outdoors and accessible. We’ll complete the service and send you a photo confirmation and flush report.
What solution do you use?
We use a biodegradable descaling solution specifically formulated for tankless water heaters. It removes calcium, lime, rust, scale, and other mineral deposits. It also includes a metal protectant to guard against rust, corrosion, and oxidation during and after cleaning.
What causes the performance drop?
Mineral buildup restricts heat transfer and water flow. A layer as thin as 0.03 inch can drive ~30% higher energy usage and cost, which is why routine flushing is so effective.
How long does a flush take?
Most services are 45 minutes to 1 hour. We set up, flush, clean filters, and restart the unit to verify flow.
Which brands do you service?
All major residential tankless brands (Navien, Rinnai, Rheem/Ruud, Noritz, Takagi, and others). If you’re unsure, text or email a photo of your unit.
Do you do repairs or troubleshooting?
We focus on preventative flushing and cleaning. If we spot something concerning, we’ll note it in your report so you can contact a licensed plumber for repairs.
What if my unit doesn’t have service/flush valves?
Text or email us a couple photos of the piping below the unit. We’ll confirm whether it’s set up for flushing and discuss options.
