You can also obtain the right fittings that you will need to operate a line from the expansion tank up to the tee-fitting inserted in the cold water supply line. For this project, you need a good plan to run a branch line off to the expansion tank from the hot water tank cold water application. Even the most successful military expeditions begin with a plan on paper. Nothing successful starts without a plan. First, however, there are steps that you must follow if you want to be successful. Steps to Installing an Expansion TankĪfter preparations, this is now the time to install.

You can finally shut off the faucet and turn off your drain valve once you notice that there is no more pressure from the water heater.

If you notice some pressure, wait for a few minutes and then repeat step 4.

After draining for some minutes, open the T&P valve slightly to test the pressure.

Don’t open the valve too fast or too much this may lead to a slide from the drain.

Release pressure from the water heater tank by opening the drain on the hot side of the closer faucet and the water heater.

You can then join a hose on the drain valve below the heater and run it to the other end of the nearest drain.

The first step is to turn off the mainline supply of water that connects directly to the cold water side of the heater.

First, let’s look at how you can prepare for installation by draining the tank: Therefore, it would be best to skip directly to the processes of installing the tank. If you are making a completely new installation, there is no need to drain anything. Before you start, you must ensure that you have enough space over the water heater to place the expansion tank. If you already have an expansion tank and want to add another one on top, you must first drain water from the water heater.

Extra ¾-inch copper fitting Preparations for Installing an Expansion Tank.

At least two ¾-inch female-threaded copper unions.

There are various supplies and tools that you must have ready while installing an expansion tank, as highlighted below:

The expansion tank has a 3/4-inch fitting joined to the cold water pipe using a tee fitting and threaded or sweat-soldered or short-length pipes. The plumbing fittings you’ll require for installation will depend on the types of pipes you have and the tank orientation.Ĭonnections during installation are made using copper fittings and pipes. However, in cases where you have limited space, you can install the tank vertically. The tank is usually positioned horizontally.

Where would you install a new expansion tank? First, use a tee-fitting above the water heater on the cold water delivery pipe.

If your system has those valves in place, it would be wise to install the tank even if your local code doesn’t make it mandatory. However, an expansion water tank isn’t necessary if your system doesn’t have any backflow or pressure limiting valves. In most cases, though, you might be forced by your local authorities to install a water tank, where you have a water heater. You get to learn about the requirements of an expansion tank when you’re applying for a plumbing permit. Installation of a water heater requires a plumbing permit. It has two sections the first one has an air chamber pressurized when the diaphragm expands, while the other section accepts expansion water when it heats. Backflow valves or pressure-limiting valves prevent the expanding water from flowing back into the central water supply unit. If you have one in place, it offers space for expanding hot water, reducing excess pressure on the pipes, fixtures, and water tank.Įxpansion tanks are essential in closed plumbing systems.

Without an expansion tank linked to the water heater, any closed plumbing system can undergo severe damage due to thermal expansion.įor instance, when you heat water from 50 to 120 degrees Fahrenheit, its volume rises by about 2%. We all know that water expands when it’s heated. An expansion tank is required in certain circumstances and can help a water heater last longer.
