How do you secure an expansion tank to the wall?

Secure bracket with two #6 x 2″ screws (provided) to wall making sure screws penetrate through wood or metal stud. Thread end of band through bracket and around body of thermal expansion tank. Secure band tightly around tank using screwdriver or 5/16 nut driver. One or two bands can be installed.

How should an expansion tank be mounted?

An expansion tank is generally installed directly above the water heater by means of a tee-fitting installed in the cold water delivery pipe. The expansion tank is usually installed vertically, though it is acceptable to install it horizontally if it is necessary because of space limitations.

Can you mount an expansion tank on its side?

Expansion tanks can be installed in any direction. Whether oriented uprightly, horizontally, or even upside down, the expansion tank will function properly without any adverse effects.

Does expansion tank need to be above radiator?

Since the radiator is lower than the engine a pressure relief and fill point that is higher than the engine is needed. This is accomplished with an expansion tank. When the radiator is high enough to act as a fill point and pressure relief an expansion tank is not necessarily required.

Does a thermal expansion tank need to be supported?

All expansion tanks (even the small 2-gallon tanks) should be supported in some way. There are a few options that plumbers use consistently.

Can a water heater expansion tank be mounted horizontally?

Can a water heater thermal expansion tank be installed sideways/horizontally? Most expansion tanks are designed to be installed vertically (stem up or stem down). You can install one sideways, but it will shorten the lifespan unless it is designed and specified by the manufacturer for horizontal installation.

Can an expansion tank explode?

In fact, the tank may explode! Thermal Expansion Can Cause Hot Water Heaters to Explode! A typical hot water heater in an “open” sys- tem has only a temperature and pressure (T&P) valve to prevent a rupture of the hot water heater (figure A). Open systems allow expanding hot water to push into the cold water line.

How close should an expansion tank be to a water heater?

The items which should be installed in sequence in the cold water line are (1) the EXPANSION TANK must be installed at least 18 inches away from the cold water inlet fitting on the water heater, (2) the PRESSURE GAUGE, and (3) the PRESSURE REDUCING VALVE, if required, see Figure 1. 3.

Why is expansion tank on the cold water line?

That is an expansion tank installed on the water supply pipe to the water heater. Its purpose is to deal with thermal expansion of water as it heats up in the water heater – to prevent water pressure from getting too high.

How often should an expansion tank be replaced?

between five and 10 years
But expansion tanks can wear out. The average life of your tank can be anywhere between five and 10 years. You can extend the life of your expansion tank by making sure that your home’s water pressure matches the air pressure in your expansion tank.

Should the expansion tank be on the hot or cold side?

Although expansion tanks can be installed on the hot side, we strongly recommend they be installed on the cold line, downstream of the shutoff valve.
