If you've recently installed or replaced a hot water heater, you may have heard about expansion tanks. Expansion tanks play a crucial role in your plumbing system, helping manage pressure fluctuations that occur as water heats and expands. At Oasis Plumbing, we often receive questions about when these tanks are necessary, particularly in Denver, where many properties are moving toward mandatory backflow prevention devices.
When Do You Need an Expansion Tank?
Expansion tanks become critical in closed plumbing systems, especially those equipped with backflow prevention devices. These devices, now required in many municipalities, including Denver, create a sealed system. Without an expansion tank, your hot water heater can experience excessive pressure as water expands, potentially leading to leaks, ruptures, or damage to your plumbing fixtures.
Even in older homes without mandatory backflow prevention devices, we highly recommend installing an expansion tank as a preventative measure. It significantly extends the life of your hot water heater and plumbing system.
Quality Matters: Choosing the Right Expansion Tank
Not all expansion tanks are created equal. Standard tanks are typically made from steel and are adequate for many applications. However, if your property has water quality issues, such as high mineral content, or if you're simply seeking the most reliable, long-lasting option, Oasis Plumbing recommends premium stainless steel tanks from Zilmet. Stainless steel tanks are corrosion-resistant, ensuring greater longevity and reliability.
Symptoms of an Undersized Expansion Tank
Choosing the correct size of your expansion tank is critical. If your tank is undersized:
- Pressure relief valve on your water heater frequently discharges.
- Noticeable fluctuations in water pressure.
- Increased wear and tear on your water heater and plumbing system.
Consult with Oasis Plumbing experts to ensure your expansion tank matches the specific needs of your plumbing system.
Signs Your Expansion Tank Is Failing or Has Failed
Expansion tanks don't last forever. Common indicators that your tank needs inspection or replacement include:
- Dripping or leaking around the tank.
- Rust or corrosion visible on the tank.
- Unusual fluctuations in water pressure.
- A hollow or overly heavy tank, indicating waterlogging.
If you notice any of these symptoms, it’s important to contact Oasis Plumbing promptly for a thorough evaluation.
