Follow these steps for proper
installa on:
Step 1:
✓
Verify that your
home is equipped
and up-to-date for
proper opera on
Installing a new water heater is the perfect
 me to examine your home’s plumbing sys-
tem and make sure the system is up to cur-
rent code standards. There have likely been
plumbing code changes since the old water
heater was installed. We recommend
installing the following accessories and any
other needed changes to bring your home
up to the latest code requirements.
Use the checklist below and inspect your
home. Install any devices you need to com-
ply with codes and assure that your new
water heater performs at its best. Check
with your local plumbing offi cial for more
informa on.

Water pressure
We recommend checking your
home’s water pressure with a pressure
gauge (Figure 4.) Most codes allow a
maximum incoming water pressure of 80
psi. We recommend a working pressure no
higher than 50-60 psi.
HOW: Purchase an inexpensive water
pressure gauge available at Lowe’s®.
Connect the Water Pressure Gauge to an
outside faucet and measure the maximum
water pressure experienced throughout
the day (highest water pressures o en
occur at night).
Figure 4 - Use a Water Pressure Gauge to make
sure your home’s water pressure is not too high.
To limit your home’s water pressure: Lo-
cate your home’s Pressure Reducing Valve
(PRV) on the main incoming (cold) water
supply line and adjust the water pressure
control to between 50 and 60 psi. If your
home does not have a Pressure Reducing
Valve, install a PRV on the home’s main
water supply line and set it to between 50
and 60 psi. Pressure Reducing Valves are
available at Lowe’s®.
BACKGROUND: Over the years, many
u li es have increased water supply
pressures so they can serve more homes.
In some homes today, pressures exceed
100 psi. High water pressures can damage
water heaters, causing premature leaks. If
you have replaced toilet valves, had a wa-
ter heater leak, or had to repair applianc-
es connected to the plumbing system, pay
par cular a en on to your home’s water
pressure. When purchasing a PRV, make
sure the PRV has a built-in bypass.

Water pressure
increase caused by
thermal expansion
Verify that you have a properly sized
Thermal Expansion Tank (Figure 5). We
recommend installing an expansion tank
if your home does not have one. Codes
require a properly pressurized, properly
sized Thermal Expansion Tank in almost all
homes. (See photo on inside front cover.)

tect the home’s plumbing system from pressure
spikes.
