The D-040 series PN 16 Combination Air Valve has the features of both an air release valve and an air & vacuum valve. For the Long version  (9" = 23cm )  please choose the D-040-L PN16 Option (see more info below: **)*Triple function Air Valve: - Air release while filling pipe lines & components- Air release while draining pipe lines & components- Air release of dissolved air in water when temperature change.* Also air suction at any vacuum condition.The air release component is designed to automatically release small pockets of air to the atmosphere as they accumulate along a pipeline or piping system when it is full and operating under pressure. The air & vacuum component is designed to automatically discharge or admit large volumes of air during the filling or draining of  pipeline or piping system. This valve will open to relieve negative pressures whenever water column separation occurs.

When thewater column returns, air is discharged through the small orifices(one orifice - 1½" model), at a rate determined by the orificeopening setting (set manually by the user). This way, air dischargeis controlled, greatly reducing the effects of slam.

Lift the lever on the temperature & pressure release valve. When you have a steady stream of water from the T&P drain line close the valve. When you have a steady stream of water from the hot water faucet, turn the faucet off. Turn the power back on at the circuit breaker.

AIR VALVESA.R.I. by Aquestia air valves in pipeline systems serve two primary functions. The first is the release of accumulated air that comes out of solution within a pressurized pipeline. This air will result in bubble formation, which will gather at localized high points along the pipeline profile. This air accumulation will occur when the bubble’s buoyancy is greater than the energy to convey the bubble with the liquid. The A.R.I. air valve used to release this free air is known as an air release valve.

Series LF15-AUS water hammer arrestors are designed to eliminate the noise from banging pipes caused by shocks of water flowing at high speed.

For this repair, you’ll need a replacement temperature & pressure release valve, a PVC drain line, a pipe wrench or adjustable wrench, an extension or cheater bar, flat blade screwdriver, Teflon tape, a garden hose, and a few rags and towels. Attach a length of garden hose to the drain valve at the bottom of the heater. Run the other end of the garden hose to the nearest floor drain or to a safe spot outside the home.

Close the shut-off valve at the cold water inlet line. Open a hot-water faucet somewhere in the house that will relieve the system pressure inside the tank. Now, open the drain valve and allow approximately one gallon of water to drain for a top-mounted temperature & pressure release valve or ten gallons for a side-mounted T&P valve. Remember the water will be hot, be sure no one is near the drain hose so they don’t get scalded. Detach the runoff tube connected to the T&P valve. Remove the old T&P valve with the wrench. You may need to use a cheater bar or short length the metal pipe for extra leverage. You may get some additional water draining, so have some rags or towels handy.

Every water heater has a temperature and pressure relief valve called a T&P valve for short. It’s an important safety feature that prevents pressure from building up that could damage the heater and even your home. Over time, the temperature & pressure release valve can corrode to the point where it doesn’t work properly. You should be able to open the valve with your hand and hear the pressure escape.

The pressure valves, or PRVs, work by opening when a pressure limit has been reached, and diverting either gas, liquid, or liquid-gas mixtures away from the ...

The second function of an air valve is to admit air into the system when the internal pressure of the pipeline drops below atmospheric pressures. By admitting air into the pipeline as the internal vacuum condition develops, the magnitude of the vacuum pressure can be reduced and as a result help prevent the pipeline from experiencing excessive deflection and/or collapse as well as help prevent the formation of a full vacuum condition in which vapor cavities may form from the fluid vaporizing. The A.R.I. air valve used in this situation is an A.R.I. air & vacuum valve. The A.R.I. air & vacuum valve is also used to discharge large volumes of air from the pipeline system when the pipeline is initially filled and after water column separation.

Before you attempt to replace your water heater temperature and pressure release valve, you should consider hiring a professional hot water repairer.
