A h2o heater expansion tank, also chosen a thermal expansion tank, is a safety device designed to protect your household plumbing from thermal expansion. The adventure of pressure damage from thermal expansion is seldom a concern for tankless water heaters, only if y'all own a tank-style heater, your plumbing system may exist at chance.

When y'all consider that 50-gallons of common cold water will, with the help of thermal expansion, become at least 52-gallons once it's heated, the boosted 2-gallons of water will no longer fit in the water heater's tank. That's where a thermal expansion tank comes in.

What is a H2o Heater Expansion Tank?

A water heater expansion tank is simply a pocket-sized tank that absorbs h2o into a bladder to reduce backlog pressure in your water heater.

In the by, when water expanded information technology wasn't a problem, the actress few gallons would but flow back into the city's water supply. Just today, the expanded water has no place to go because current plumbing regulations prohibit it from inbound the city's system where it could contaminate the public water supply.

With the required bank check valves and backflow preventers in place, your water pipes, water heater and even some appliances must bargain with the increased pressure acquired by thermal expansion. This causes unnecessary habiliment-and-tear which can upshot in damage to hot water-use appliances, including your water heater. Information technology could fifty-fifty be the cause of a bursted pipe!

How a Thermal Expansion Tank Works

Within the expansion tank is a pressurized air bladder which absorbs the additional water by expanding and contracting.

As the h2o in your water heater becomes hot, information technology expands and increases the pressure within the tank and plumbing system. However,  instead of allowing the pressure to build, the excess water enters the expansion tank.

When a faucet within the firm opens (or the water cools) the water inside the thermal expansion tank is released back into your hot h2o organisation. An expansion tank but contains overflowing water. It does non store water on a permanent basis.

Why Practice I Need an Expansion Tank?

Going without a water heater expansion tank is risky. Although, many water heaters don't take an expansion tank, we highly recommend adding one. Information technology'll protect your plumbing, appliances and your water heater.

Inundation hot water can cause the force per unit area in the water tank to rise to unsafe levels, which may result in the components breaking. Every bit you might imagine, flood hot water can also leak out  through the T&P Valve and cause all-encompassing water harm.

Even when components don't suspension outright and no leaks develop, there can still be negative consequences for going without an expansion tank. The increased strain caused past an overly total tank of hot water can shorten the service life of the heater, not to mention that the components may wearable out sooner than expected.

Finding the Correct H2o Heater Expansion Tank

Installing an expansion tank to your hot water heater is not only a good idea, its also a requirement in near areas, and determining the correct size for your system is important. Unfortunately, when it comes to thermal expansion tanks there isn't a one-size-fits all option.

How to Properly Size an Expansion Tank

Selecting the correct size is relatively easy. There are two main factors that need to exist taken into account:

• Water Heater Chapters - This information tin be establish on the manufactory label attached to your water heater.
• Household Water Pressure  - The h2o pressure level, measured in psi (pounds per square inch) within your abode's plumbing tin can exist measured with a gauge. Only attach the gauge to a hose or faucet and turn on the water. It'due south a best practise to check your water pressure over a 24-60 minutes period.However, another option is to contact your water visitor.

Continue in listen, y'all should install a pressure reducing valve if your water pressure is in a higher place 80 psi. The platonic h2o pressure is between l to 60 psi.

Water Pressure Gauge

This water pressure gauge comes with adapters that permit yous to measure the water force per unit area in multiple locations.

General Guidelines for Sizing an Expansion Tank

This nautical chart volition help yous properly size an expansion tank to your residential h2o heater. It assumes that the temperature is set to 150-degrees.

H2o Heater Capacity	Supply Pressure (psi)	Expansion Tank Size
40 to 60-gallon	40-l psi	two-gallon
40 to lx-gallon	60-80 psi	three.2-gallon
80-gallon	40 psi	two-gallon
fourscore-gallon	l-60 psi	iii.2-gallon
80-gallon	lxxx psi	4.4-gallon

If your h2o heater falls outside of these static supply pressure readings or capacities, it's best to contact a professional person. They can come out and make the necessary calculations and even install the expansion tank for you.

What Happens if the Expansion Tank is the Wrong Size?

Purchasing the right sized thermal expansion tank is important, but if you lot're in dubiousness, it's best to error on the side of larger than smaller.

An expansion tank that is as well large for your arrangement will still be able to safely handle the actress water. However, a tank that's as well small can trigger the temperature and force per unit area relief valve to open and then the excess force per unit area is relieved.

How to Install an Expansion Tank

If y'all have a bit of mechanical skill and enjoy taking on DIY tasks, you should exist able to install an expansion tank yourself. Or, y'all can simply contact a professional to practise the task for you.

Installing an Expansion Tank

• Every bit described to a higher place, determine your household h2o pressure with a force per unit area guess. If the force per unit area is higher up fourscore psi, install a pressure reducing valve.
• Cheque the air pressure on the expansion tank with a tire gauge.
• Adjust the air pressure of the expansion tank to match the maximum household water pressure. Using a hand pump Non an air compressor.
• Install the tank on the cold water line (encounter video for details).
• Open a faucet and allow it to run until you have a steady stream of water. This will remove whatever trapped air within the tank.

How to Maintain an Expansion Tank

Water heater expansion tanks need regular maintenance to ensure optimal functioning. Virtually experts recommend that you or a licensed professional perform routine maintenance annually.

Why is Maintenance Needed for an Expansion Tank?

Expansion tank's are designed with an internal float that separates the air and water. Through a process called "diffusion" the float will leak air. The leak can often be at a charge per unit of ane psi a year, which is enough to make a difference afterward only 12 months.

If the internal bladder ruptures the expansion tank will fill with water and not properly drain. When this happens, you lot'll need to purchase another expansion tank since there's no way to repair the bladder. The average lifespan of a thermal expansion tank is half-dozen-years, provided it was installed correctly.

Checking the Bladder

We'll give you lot an easier method, but if yous call a professional to audit your expansion tank, these are the steps he'll use:

• Plough off the supply of water to your house and salvage the force per unit area by opening a faucet.
• Remove the cap to the valve stem on expansion tank and attach a tire pressure gauge. The pressure should exist above 75 psi.
• If there is no air pressure within the tank, the expansion tank has failed. You lot will need to replace it with a new i.
• If at that place is pressure inside the tank, you'll need to cheque the water pressure level.
• The expansion tank and water pressure should be similar. If its non similar, you lot'll demand to use a hand pump to add together air to the expansion tank.

All the same, if y'all're looking for a quick and like shooting fish in a barrel way to inspect your tank you tin can simply printing the Schrader valve that'south located on the outside of the tank.

If air comes hissing out when you press down on the valve, the bladder is in good working order. But if water comes dripping out instead, the bladder has most probable ruptured and you lot'll need to buy a new one.

Checking the PSI

Subsequently checking that the bladder is in skilful repair, y'all'll desire to cheque the tank's psi pressure. Your owner'south transmission volition accept the right psi for your tank. Y'all may desire to write this number down on the tank and then you lot don't need to expect it up again in the time to come.

Take the reading with a tire pressure estimate. If the psi is too high, you lot can but let some air out past pressing down on the valve until enough air has escaped. If the psi is too depression, you lot'll need to add together some air with a tire pump.

We highly recommend using a hand pump instead of an air compressor when adding air. An air compressor could easily rupture the float.
