Connection to a non-vented faucet WILL DAMAGE THE TANK and void the warranty.
A kinked tank outlet tube or debris in the faucet obstructing the free ow of water from the
tank will subject the tank to pressures exceeding its design limits and cause the tank to leak.
The included Pressure Regulating Valve (PRV) must be installed with this Hot Tank to prevent
damage from excessive pressure and maintain the warranty.
WARNING - USE OF AN IN-LINE INSTALLATION OF A WATER CHILLER WITH A
WATERSTONE FAUCET OF ANY KIND WILL VOID OUR WARRANTY.
Since 2005, Waterstone has continued to advise all of our customers against the installation of any brand of
in-line water chiller unit with our faucets. Compressor style chiller units have been proven to arbitrarily exceed
the standard household in line pressure ratings causing the faucet inlet connection line to burst and create the potential for water damage
claims in the eld.
Waterstone can not and will not be held liable for damages created by a use for which our products were not designed. Waterstone will
only recommend the installation of a water chiller in the vented side (in place of a hot tank) with one of our Hot or Hot & Cold Filtration
faucet models.
3 LINE VENTED FAUCET
HOW A VENTED FAUCET WORKS
Water from the blue supply tube (A) ows
through the PRV valve (B) and into the

faucet base (C). Water is then diverted into

CHOOSE TANK LOCATION
Find a location under your sink that has access
to an electrical outlet and close enough to
reach faucet tube leads without kinking. For the
tank to operate properly, it cannot be installed
beyond the reach of the factory tubing.
WARNING! DO NOT PLUG IN THE
HOT TANK UNTIL IT IS FILLED WITH
WATER. HEATING THE TANK WHILE
EMPTY WILL DAMAGE UNIT

WATERSTONE MODEL 5000 BASIC TROUBLESHOOTING TIPS
MY TANK WILL NOT HEAT WATER
The model 5000 Hot Tank will take between 10 and 20 minutes to heat water to the setting specied on the temperature control dial. If after
that time your tank is not heating water, make sure that it is plugged into a 110v electrical outlet. Keep in mind that sometimes the outlets
under your sink are set up to be switched on with the garbage disposal. A good way to test the functionality of your outlet is to plug something
else, like a lamp, into that outlet. If you have conrmed that your outlet is functioning properly and your tank still does not heat water after 20
minutes, please call Technical Support at 888-304-0660.

MY FAUCET DRIPS FROM THE SPOUT
After hot water has been dispensed during normal usage, your tank immediately starts the reheating process which brings the water back up to the
temperature you have selected with the temperature control dial. During this time, it is very normal for the faucet spout to drip for a few minutes
while the water in the tank is reheating. What you are seeing is steam condensation collecting on the inside of the spout and again, this is very
normal.
OKAY, BUT MY FAUCET DRIPS ALL THE TIME
The model 5000 is a zero-pressure vented system. What this means is that the tank is designed to vent air from the tank through your spout at all
times. If your tank is dripping constantly, this is a symptom which may be caused by one of two things. The rst thing to inspect and conrm is that
the clear vent line which goes between the tank and the faucet is as short and as straight as possible. Any loops or kinks in this line will inhibit the
tank from creating the required internal vacuum for normal operation. The next thing to ensure is that the tank is being supplied sucient water
pressure on its inlet side. When the model 5000 hot tank does not get 60psi at 1 gallon per minute (both minimum requirements), it can not create
the vacuum needed to draw water in the spout back down into the tank when the valve is closed. Especially at higher temperature settings where
expansion is present, this will cause the faucet to vent water out of the spout. This typically manifests its self in the form of a slow, steady drip. If you
have measured the pressure being supplied to the tank to be 60psi range, and have conrmed that the clear vent line is straight and free of loops
or kinks, dripping should not occur for any longer then a few minutes after you have used the tank. If you still experience problems at this point,
please call Technical Support at 888-304-0660.
MY WATER HAS A BAD TASTE OR ODOR
Waterstone Faucets products utilize food grade NSF approved plastics for the cold water inlet portion of the unit and stainless steel for the hot water
reservoir. The possibility of leaching chemicals, which could cause a bad taste or odor, is eliminated by the use of these materials. The most common
cause of bad taste or odor is caused by unltered water. When hot water is dispensed, the odor and taste of these chemicals becomes accentuated
by the steam and vapors still present in the hot water. The other common cause is plumbers putty or “pipe dope” used for sealing threads in new or
newly repaired plumbing xtures feeding the hot water tank. This results in a “metallic” taste in the water and can be cured by purging the hot tank
and cleaning out any collected debris from the tip of the faucet.
MY FAUCET IS SPITTING AND STEAMING FROM THE TIP
One of two things is most likely happening in this case. First, the hot tank has not been used for a prolonged period of time (usually several weeks)
and has been allowed to evaporate down to a low internal water level exposing the heating element. As the heating element cycles on, the unit
overheats at the water surface and creates steam. As a preventative remedy for this situation, remember to turn down the thermostat to the hot
tank if you are going to leave your home for an extended period of time, and make sure to run the tank periodically to keep the ll level up to its
normal operating levels.
The second possibility is that the thermostat is sticking in the closed position causing the heating element to run continuously overheating the
tank resulting in spitting and steaming out the tip of the faucet. In this case, rotate the thermostat control knob on the front of the tank through its
full range of setting several times to allow the bi-metal coil to “un-stick” and resume its normal function, then reposition the control knob to your
desired temperature. If the problem persists, unplug the hot tank and call customer service/tech support.
