How Tankless Bros Became St. Johns County’s Hot Water Heater Flushing Pros

Why It’s Risky to DIY

From not having the right tools, time or technical knowhow tankless hot water heater maintenance can quickly become a job….instead of a weekend chore! 

Just like changing the oil in your car….just because you know how to; does not mean you want to!

1: Risk of Damaging the Unit

The filter is connected to the internal plumbing of your unit. Improper handling can crack fittings, damage sensors, or trigger the unit to shutdown and go into safety mode. One wrong turn can result in leaks or complete system failure — which isn’t a cheap fix.

2: Special Tools Required

You may need:

  • Submersible Pump
  • 5/8 inch internal diameter hoses
  • Isolation valves
  • Descaling kit
  • Filter removal tool
  • Knowledge of how to depressurize the system safely

3: It’s Not Just About the Filter

Flushing and replacing the filter is often part of a broader maintenance routine. DIYers often skip or confuse steps like:

  • Flushing the proper direction
  • Cleaning out the internal cabinet
  • Resetting the unit after servicing

Missing any of these can lead to performance issues.

4: Small Mistakes Can Be Expensive

Trying to save money by doing it yourself can backfire. A stripped valve, broken connector, or water damage from improper flushing can lead to repair bills in the hundreds — or even thousands — of dollars.

Let a Professional Handle It

Our technicians are trained to:

  • Safely flush and descale
  • Replace the inline filter correctly
  • Clear and inspect exhaust system
  • Inspect your heater for any wear or hidden issues
