T&P Relief Valve Maintenance

Read and follow the opera ng and

annual maintenance instruc ons

provided by the manufacturer of the

T&P Relief Valve (yellow label a ached

to T&P Relief Valve). Minerals in the

water can form deposits that cause

the valve to s ck or create blocked

passages, making the T&P Relief Valve

inopera ve. Follow these guidelines:

• At least annually, operate the T&P

Relief Valve manually to ensure the

waterways are clear and the valve

mechanism moves freely (above).

Before opera ng the valve manually,

check that it will discharge in a place

for secure disposal. If water does

not ﬂ ow freely from the end of the

discharge pipe, turn OFF the power

to the water heater. Call a qualiﬁ ed

person to determine the cause.

WARNING! Hot water will be

released. Before opera ng the T&P

relief valve manually, check that it will

discharge in a safe place. If water does

not ﬂ ow freely from the end of the

discharge pipe, turn the power to the

water heater OFF. Call a qualiﬁ ed

person to determine the cause.

• At least every ﬁ ve years, have a quali-

ﬁ ed person inspect the T&P Relief

Valve and discharge pipe. Damage

caused by corrosive water condi ons,

mineral deposits, or other problems

can only be determined when a qual-

iﬁ ed person removes and inspects

the valve and its components.

• Note that a dripping T&P Relief Valve

is usually caused by the home’s water

pressure being too high or the lack

of a Thermal Expansion Tank. If your

T&P Relief Valve drips, see page 20.
