HOW YOUR WATER
HEATER SAFETY TANK
WORKS
Your water heater safety tank is
a specifically designed pressure
absorbing device. It protects your
entire plumbing system, including
your water heater, from over
pressurization caused by thermal
expansion. As water is heated, it
expands, and since water is not
compressible, a rapid increase of
pressure in the water heater and
throughout the entire plumbing system
results. This increase in pressure is
known as thermal expansion, occuring
every time your water heater heats
water, when the expanded water is
not allowed to return to the supply
line. Common problem signs of high
pressure caused by thermal expansion:
• High surges when opening faucets.
• Relief valve on water heater opening
to release high pressure
- DANGER:
NEVER PLUG RELIEF VALVE.
• Frequent faucet washer failure rate.
• Short water heater life.
• Problem deformities with pipes and
fittings.
Your water heater safety tank
operates as a collection point to
accept thermally expanded water
(Figure 1). As water enters the tank
(Figure 2), the diaphragm is pressed
downward, compressing the captured
air cushion in the tank. The air volume
is specifically engineered to control
pressure well below the water heater
pressure relief valve setting. As water
is used (Figure 3), the thermally
expanded water is expelled from the
tank back into the piping system by
the compressed air cushion.
PRE-INSTALLATION
CHECK LIST
1. Remove tank from box and inspect
for any damage. If damage is evident
return immediately to place of
purchase.
2. Use pressure gauge or tire gauge
to verify precharge pressure in the
tank. Precharge should measure 40
psi (± 5psi depending upon gauge
accuracy).
3. Locate position in piping system
to install your water heater safety
tank. The ideal position is anywhere
on the cold waer line leading to the
water heater. Ensure that the tank’s
position will not interfere with the
ceiling, wall, or any appliances once
it is installed.
4. The saddle valve is designed to be
installed on a
HORIZONTAL PIPE
ONLY
. The tank must be positioned
to
HANG DOWNWARD
from the
horizontal pipe (figure 4, page 2).
5. Utilize proper pipe hangers and
supports to handle a possible future
waterlog condition of the tank. This
support must handle a weight of
approimately 40 lbs.
