8.  Plug the line cord of pump into a 115V 
outlet.  Be sure to route the power cord 
so that it does not touch the exhaust vent    
piping of a gas or oil fired hot water heater.

9.  Using the timer (see pg. 6), set the pump 
to operate around your peak use times. (eg 
30 minutes before the first shower until 15 
minutes after last shower).

Valve Location

For the greatest effect, the valve should        
be located at a faucet with the greatest 
piping distance from the hot water heater.   
If your home has a branched hot water line, 
more than one valve may be necessary.

Valve Installation

Note: Do not use teflon tape or pipe dope on 
the valve threads.

1.  Close both the hot and cold water angle 
stop valves below the sink. (see Picture #3)

2.  Disconnect the risers. (see Picture #4)

3.  Connect the 

1/2”X1/2”

 flex hoses to the 

ports on the valve marked 

“Hot Out”

 and 

“Cold Out”. (see Picture #5)

4.  Connect the 

1/2”X3/8”

 flex hoses to the 

ports on the valve marked 

“Hot In” and

“Cold In”

. (see Picture #5)

Please note: By plumbing convention, the 
hot water is on the left side and cold water 
on the right, when looking at the sink.  Your 
piping may be different.
