The Unsung Hero of Your Water Heater: Your Pressure Relief Valve

Jan 13, 2025

As a Denver homeowner, you depend on your water heater to provide hot water for showers, laundry, and more—especially during Colorado’s chilly winters. But did you know that one small component, the pressure relief valve (PRV), plays a critical role in keeping your water heater safe and functional?

In this blog, we’ll get into the importance of your water heater’s pressure relief valve, how Denver’s unique weather conditions can impact its performance, and why professional maintenance from a trusted plumber like Copperhead Plumbing is essential.

What Is a Pressure Relief Valve?

The pressure relief valve is a safety feature on your water heater designed to release excess pressure when it builds up inside the tank. Without it, your water heater could become a dangerous hazard, risking bursts or explosions from uncontrolled pressure.

How Weather in Denver Affects Your Pressure Relief Valve

Denver’s climate is a mix of high-altitude conditions, fluctuating temperatures, and mineral-rich water, all of which can take a toll on your water heater and its components:

  1. Temperature Swings: Denver’s wacky fluctuations in temperatures can cause the water in your heater to expand and contract, putting additional strain on the pressure relief valve.
  2. Hard Water: The mineral-rich water common in Denver can lead to sediment buildup in your water heater, which can clog or damage the pressure relief valve.
  3. Altitude: The thinner air at Denver’s altitude can impact water heater performance, making proper maintenance even more crucial.

Signs Your Pressure Relief Valve May Need Attention

Keep an eye out for warning signs or “red flags” that your pressure relief valve might not be functioning properly:

  • Leaking Water: If water constantly drips from the valve, it may be malfunctioning or dealing with excessive pressure. Call a Copperhead Plumbing tech immediately if you see signs of leakage. 
  • No Water Release: If the valve doesn’t release water during high-pressure situations, it could be clogged or stuck.
  • Strange Noises: Gurgling or banging sounds from your water heater could signal an issue with the valve or excess sediment buildup.
