CAUTION
GRANITE GROUP LIMITED PRODUCT WARRANTY INSTALLATION, WARNINGS, AND OPERATION INSTRUCTIONS
PET SERIES THERMAL EXPANSION TANKS
OPERATION
This thermal expansion tank designed to maintain safe
water pressures in a domestic water heating system
that utilizes a back-flow preventer or check valve. It
features a butyl rubber diaphragm and polypropylene
liner to separate the system water from the tank's inner
walls and pre-charge. The system connection is
stainless steel and the tank is finished with an
appliance quality paint to minimize corrosion.
WHAT IT DOES
Adding a back-flow preventer, water meter with a
check valve, or any other "no return" valve to a
domestic water heating system creates a closed-loop
system. When water heats up, it expands which can
cause unsafe operating pressures and cause nuisance
operation of the water heater's safety relief valve.
Adding a thermal expansion tank to the cold water inlet
of the water heater creates a reservoir for he expanded
water. Water enters the tank and is released back into
the system on demand. The goal is to avoid dripping
relief valves and improve the safety of the system.
stalled by a Qualified Professional
following all local and national plumbing and
electrical codes. Read and understand fully
the instructions included here and those on
The Granite Group website which are
updated on a regular basis. This product
must be inspected annually by a qualified
professional for any signs of corrosion or
leakage and replaced immediately if these
signs are present. Failure to follow these
instructions may result in serious injury or
death and/or property damage and will void
the product warranty.
This product
must be in-
maximum pressure of 150 psi and a maximum temperature of 200 F. A
properly sized pressure relief valve set at a maximum of 150 psi must
be installed in the system. This tank is shipped with a pre-charge of 40
psi and any adjustment to the pre-charge must be done prior to
installation and at ambient temperature. Do not adjust the pre-charge of
this tank if the product is corroded or damaged or shows any signs of
diminished integrity. The maximum allowable pre-charge in this
expansion tank is 80 psi. Do not adjust the pre-charge of the expansion
tank with the system under pressure. Failure to follow these instructions
is UNSAFE and may result in serious injury or death and/or property
damage.
piping will in time leak. This tank must be installed in a location that
allows for easy access, visual inspection and where water leakage will
not cause property damage. Installation must include a means for
adequate drainage. This tank must not be installed in a location that is
subject to freezing. This tank must be installed in the vertical position.
The manufacturer of this product is not liable or responsible for any
water damage associated with the installation and/or failure of this
product. Failure to follow these instructions will void the warranty and
may result in personal injury, death and/or property damage.
This tank is intended for use on potable
water systems only and any other use
may be dangerous and will void the warranty. This product's
performance and lifespan can be significantly and adversely impacted
by aggressive water conditions. A water test should be conducted at
regular, periodic intervals specifically looking for corrosive water, acids
and other relevant water contaminants which, if present, must be
treated immediately and appropriately. The system piping must be
properly grounded to Earth and a dielectric union is recommended in
the installation. Failure to follow these instructions may result in serious
injury, death and/or property damage.
PET SERIES
This expansion tank and the entire system must be checked annually by a qualified professional.
Visually examine the tank and its connection to the system piping looking for any signs of water leakage or corrosion on the
exterior of the tank or the connection.
If this expansion tank shows any visible signs of leaking, corrosion or rusting, the tank must be replaced
immediately to avoid personal injury or property damage. Do not adjust the tank air pressure if there
are any signs of corrosion on the tank. Failure to follow these instructions may result in serious injury or death and or
property damage.

LOCATION
Select a location where a water leak will not cause prop-
erty damage and provides adequate means for water
drainage. This expansion tank and the associated piping
may in time leak. The manufacturer is not responsible for
any water damage that may occur in association with the
expansion tank installation.
Disconnect or shut off the electrical
power source to the water heater.
Shut off the water supply to the system and remove all
water pressure from the system. Failure to follow these
instructions may result in serious injury or death and or
property damage.
The tank is designed to be supported by the system
piping. Make sure that there is adequate means of
supporting the system piping and if necessary add
strapping, brackets or pipe hangars.
DO NOT INSTALL THIS EXPANSION TANK IN THE
HORIZONTAL POSITION.
Install the expansion tank in the incoming water line to the
water heater between the water heater and the backflow
preventer or check valve (see Fig. 1). Adequate thread
sealant (pipe dope) must be added to ensure a leak free
installation.
Before turning on the water supply to the system, open a
hot water faucet to prevent any damage to the water
heater and remove air from the system piping. Turn on the
water supply and inspect the installation for water leaks
paying close attention to the connection between the ex-
pansion tank and the piping.
Follow the water heater manufacturer’s instructions for
proper start-up of the heater and the system.
Remove the protective cap from the air valve.
Check the tank pre-charge pressure using a standard tire pressure gauge.
If required add air to the tank using a manual bicycle tire pump until the proper pre-charge pressure is reached.
Replace the protective cap on the air valve.
