What you're noticing
Signs Your Tankless Needs Service
If you smell gas, leave, then call the gas company from outside.
- An error code on the unit or remote
- Water swings hot, then cold, mid-shower
- No flush in over a year
Our faith, our standard
Flush on Schedule, Not on Sales
We believe honest work honors God. Here is what that looks like.
We'll Show You How to Do It Yourself
If you're handy and have service valves, it's a fair DIY job, and we'll walk you through once.
We Won't Push a New Unit
Most error codes mean a part or sensor, not a dead heater. If it's done, we'll show why.
Plumbing for a Greater Purpose
A portion of every job goes to a local ministry.

What to expect on a flush visit
Before We Arrive
We ask brand, model and any error code so we bring the right parts.
During the Visit
Gas and power off, unit descaled, filter cleaned; hot water off 1 to 2 hours.
When We Leave
We test hot water, clear codes, show the scale, and say when to flush next.

How a flush works
Clears the Scale Our Water Leaves Behind
Hard water scales the heat exchanger; we pump descaler through until it runs clean.
- Steady hot water at your setting
- Filter, burner and venting checked
- Catches problems before error codes
When a flush won't fix it
- Flushing can't undo a scale-damaged heat exchanger
- Units without service valves need them added first

Tankless Repair & Flush FAQs
How much does a tankless flush cost?
Most standard flushes land between $165 and $275. If we find a part that needs replacing, we stop and price it before doing more.
How often should I flush a tankless here?
Once a year with New Braunfels water. With a softener ahead of it you can often go longer; check your maker's manual too.
What's the cold burst I get between showers?
Often normal: water in the pipes cools, and the unit takes a few seconds to fire again. Long cold stretches mid-shower are worth a look.
Can I flush it myself?
Yes, with service valves on the unit, a small pump, two hoses, a bucket and white vinegar or descaler. Turn off gas and power first and follow your maker's steps.
Is an error code an emergency?
Usually not: many point to scale, airflow or ignition, and some clear after a flush. If you smell gas, see scorch marks, or water is leaking, shut off gas and water and call right away.
