If your water heater is failing or your shutoff valve is corroded, replacing the system early can save you thousands. In this real job, Arch Plumbing installed a 40-gallon gas water heater and corrected unsafe valve corrosion—saving the homeowner over $1,300 compared to a competitor’s quote.
This video captures a real water heater installation performed by our licensed plumbing team. During the job, we discovered a severely corroded shutoff valve that needed immediate replacement. Addressing this issue prevented future leaks, water damage, and safety risks—while keeping costs fair and transparent.
Why Corroded Shutoff Valves Are a Serious Problem
Shutoff valves control water flow to your water heater. When corrosion sets in, they can:
- Fail during emergencies
- Leak without warning
- Break when turned off
- Cause water damage or gas safety issues
Many homes across St. Charles County and St. Louis have older plumbing systems where corrosion is common. Ignoring it can turn a routine repair into a major emergency.
What We Did During This Water Heater Installation
During this installation, our plumbers:
- Installed a 40-gallon gas water heater
- Identified a corroded shutoff valve
- Reworked and replaced unsafe components
- Ensured proper operation and code compliance
This wasn’t just a replacement—it was a safety upgrade.
The Real Cost Difference Homeowners Should Know
The homeowner previously received a quote of $3,400 from another plumbing company.
After reviewing the job and completing the work properly, the total savings came out to at least $1,362.
Why pricing varies so much:
- Some plumbers upsell unnecessary replacements
- Others avoid fixing underlying issues
- Materials and labor quality differ greatly
At Arch Plumbing, we focus on what actually needs to be done—nothing more, nothing less.
Why Transparent Pricing Matters for Water Heater Replacement
Water heater installations should never feel confusing or pressured. We believe homeowners deserve:
- Clear explanations
- Honest recommendations
- Fair, upfront pricing
If something needs to be replaced, we show you why. If it doesn’t, we won’t push it.
