For the greatest effect, the valve should be located at a faucet with
the greatest piping distance from the hot water heater. This can be
determined by locating the sink faucet with the longest wait time for
hot water. If your home has a branched hot water line, more than
one Sensor Valve may be necessary. Additional Sensor Valve kits
can be found at some retail locations as well as the Watts website
www.PremierH2O.com or by calling us toll free at 1-800-752-5582.

Sensor Valve Installation
3/8" Stop Valve Installation
Step A –
Close both the hot and cold water stop valves below the
sink. (See Picture #4).
Step B –
Place supplied rubber washers in female end of adapters.
Attach adapters to both “Cold Water Out” and “Hot Water
Out” ports of Sensor Valve.
Finger tight plus a quarter
turn with wrench.
Step C –
Disconnect existing supply line connection from both hot
and cold stop valves. (See Picture #4). Take disconnected
end and attach to the adapter installed on the “Hot Water
Out” and “Cold Water Out” connections respectively.
Step D –
Connect the 3/8” side of the new fl ex hose to the hot water
stop valve and the 1/2" side to the “Hot Water In” port of
the Sensor Valve. Repeat for the remaining fl ex hose to the
cold water stop valve. (See Picture #5).
Step E –
Open the hot water stop valve and proceed to
Step B of
Step 2.1 Check Sensor Valve Operation
(See Page 4).
STEP 2
Step B –
Drain the water from the hot water pipes by opening a hot
water faucet in the house. Let the water run until it stops
fl owing. Then drain remaining water from hot water heater
spigot. Leave the faucet in the house open until pump in-
stallation is complete. If water does not stop fl owing, check
to make sure the water to the hot water heater has been
completely shut off.
Step C –
Disconnect the hot water heater at the hot water
discharge. (See Picture #1)
Step D –
Install pump onto the water heater discharge, using the
3/4" female fi tting and gasket supplied on the pump. The
pump should be installed so that the pump is pumping
away from the hot water heater, towards the house. Con-
fi rm the direction of pumping by observing the fl ow arrow
on the side of the pump housing. (See Picture #2) Be sure
that the pump is not touching the exhaust vent piping
(chimney) of a gas or oil fi red hot water heater.
Step E –
Connect the hot water line to the 3/4" NPT discharge of
the pump. When connecting to a 3/4 female NPT connec-
tion, use pipe dope or Tefl on tape to seal the threads. If a
gasketed, fl exible copper water heater connector is used,
pipe dope or Tefl on tape is not required.
Step F –
Reopen the supply valve to the hot water heater and allow
the water to run until all the air has been purged from the
piping.
Step G –
Close faucet inside the house.
