Expansion Tank Installation

As their name suggests, expansion tanks provide a place for water to go when it exceeds the capacity of your plumbing system. If yours is a closed plumbing system, an expansion tank is an essential safety device. Without one, your home could suffer leaks or even burst pipes in extreme cases. An expansion tank’s role is to relieve excess pressure in your plumbing to prevent those issues.

Typically, you’ll find an expansion tank installed along the cold water line that feeds your water heater. That puts it in a perfect position to handle overpressure events in your plumbing. If your home requires one, our expert plumbers can install it with minimal disruption.

If you need an expansion tank in Rochester and don’t have one, issues may include:
  • Premature water heater failure
  • Plumbing leaks
  • Water hammering
  • Decreased plumbing system lifespan

Expansion Tank Replacement

With an average lifespan between five and 10 years, expansion tanks frequently require replacement. However, it isn’t always immediately obvious when the time has come. One way to find out is to schedule an inspection by our thermal expansion tank service specialists. We will test your expansion tank to determine whether it needs replacement. Otherwise, there’s a simple way for you to check the condition of your expansion tank. It’s not a substitute for professional diagnostics, but it is useful nonetheless. To do it, knock on the side of your expansion tank. It should emit a hollow sound if it’s in good working order. If you hear a dull thud instead, contact us for thermal expansion tank service.

You should also look for the following signs that may indicate the need for a new expansion tank:
  • Tank is over 10 years old
  • Rust or corrosion on the tank
  • Tank requires frequent repair
  • Tank shows signs of leaks

Expansion Tank Repair & Diagnostics

In most cases, the simplest solution to an expansion tank issue is to replace it. However, there are a few circumstances where plumbing repair is a viable option. Our plumbers start with a visual inspection to assess the tank and fittings for leaks. They then drain the tank, check it, and pressure-test it. If issues are found, we provide repair options.

Some common expansion tank issues we can fix include:
  • Loose fittings
  • Worn seals
  • Pressure regulation issues
  • Leaking connections

Water Heater Expansion Tanks

If you need a water heater expansion tank in Rochester, you’re not alone. They’re the most common type of expansion tank found in local homes. They work alongside your storage-tank-style water heater to prevent it from experiencing excessive pressure-related wear. Typically, any home with a check valve on its main supply line and a storage tank heater will need one. In that case, we can make the required alterations to your plumbing and install the tank you need.

A water heater expansion tank in Rochester provides the following benefits:
  • Extends water heater lifespan
  • Improves water heater efficiency
  • Maintains consistent household water pressure
  • Reduces risk of leaks

Boiler & Hydronic System Expansion Tanks

Although less common, homes with boilers or hydronic heating systems may need an expansion tank, too. Our plumbers can install and service those, as well. We carry a wide range of boiler expansion tanks to suit any need.

Expansion Tank Service FAQs

We’ve installed and serviced expansion tanks in Rochester for over 80 years. Here are some questions we’ve heard most frequently and their answers.


No, there are different types of expansion tanks for the two applications. Water heater expansion tanks feature anti-corrosion measures and operate at higher pressure. Boiler expansion tanks can handle higher temperatures.

Water heater manufacturers require an expansion tank when your plumbing system calls for it. If your plumbing requires an expansion tank and you don’t have one, the manufacturer won’t honor your warranty. That’s because any damage suffered by your water heater could be a result of inappropriate pressure in your plumbing.
