What does a discharge pipe do on a water heater?
A correctly installed TPR discharge pipe directs this scalding water to discharge to a safe location to the exterior or drain location. Water heater manufacturers state that a TPR discharge pipe is required to direct hot water to the exterior or a suitable drain location.
Where does pressure relief pipe go?
The pressure relief drain pipe (1) from the boiler should be at least 15mm diameter copper pipe and run downwards, away from any electrical equipment or other hazard, preferably to an external drain or soak away.
Where should pressure relief valve drain to?
The valve should be connected to a discharge pipe (also called a drain line) that runs down the length of the water heater tank. This pipe is responsible for routing hot water released from the TPR to a proper discharge location.
Can you discharge a PRV into waste pipe?
It is now possible for the PRV discharge to be directly connected to the internal waste. The condensate drain can be connected below the tundish. Ideal Boilers give advice on how to do this in one of their technical bulletins (AD 117), this hotun installation guidance tells you all you need to know.
What is the max height a relief valve discharge pipe must terminate off the floor why?
6 inches
Item 10 requires the relief valve to terminate no more than 6 inches (152mm) above the floor surface, a waste receptor or floor drain in order to prevent hot water discharge from being directed onto a building occupant that may be nearby.
Can you use PVC for water heater relief valve?
No. PVC pipe is not rated by the building code for use with hot water, so the installation shown above is wrong and unsafe. If the temperature and pressure relief (TPR) valve opens because the water heater is overheating, the water will be over 200ยบ F.
How do you drain a pressure release valve?

For most units, open the water pressure relief valve by simply lifting the valve up until the attached brass stem rises. When you do this, hot water will rush out of the pipe near the bottom of the water tank.
Why does my hot water heater overflow keep discharging water?
Causes of Excess Pressure in a Water Heater
Since water expands as it’s heated, higher-temperature water occupies more volume, which, in the confines of a water heater, results in increased pressure. If the pressure increases too much, your relief valve will activate, releasing water through the drain pipe.
Do you open pressure relief valve when draining water heater?
It’s important to remember to close the pressure relief valve on the hot water heater when you are through draining it. Otherwise, water will run out the valve and through the discharge pipe once it refills.

What causes too much pressure in water heater?
In short, when the temperature or pressure of the water heater gets too high, the valve opens, and releases water that’s causing the increase in pressure. The problem is that many homeowners don’t realize they need to be testing their T&P valves every 6 months, and replacing them every 5 years.
How do you reduce the pressure on a water heater?
