NOTE: Save Instructions For Future Use
PLUMBER’S TIP:
To check for a leaky flapper, slide the
Float Lock to the off position after the tank
is full of water. Do not use the toilet for 1 hour.
After the hour, recheck the water level
inside the tank. If the water level has dropped,
there is a problem with the flapper’s seal.
PLUMBER’S TIP:
Whenever the main water supply to the building
is turned off, debris can get into faucets,
aerators and toilet fill valves when the water is
turned back on. To prevent this problem,
engage HydroClean’s patented Float Lock and
run the bath tub until the water is clear,
then disengage the Float Lock to fill the tank.
PLUMBER’S TIP:
Taking the time to adjust
the Mini-Valve for the
proper amount of water
added to the bowl can
make your toilet up to
30% more efficient
without effecting
flushing power.
WARNING
DO NOT USE IN-TANK DROP-IN TOILET
BOWL CLEANERS. Use of such products will
RESULT IN DAMAGE to tank components and MAY
CAUSE FLOODING and PROPERTY DAMAGE and
VOID WARRANTY.
DO NOT over tighten nuts or tank/bowl may crack.

If you have installed the HydroClean fill valve,
there’s no need to turn off the water at the supply.
Simply, engage the Float Lock and flush the toilet.

Shut water off, flush toilet to empty tank
and remove old flush valve.
Remove the Smart Nut at the bottom of the valve. Familiarize
yourself with the Positive Lock Mechanism and not how it
locks the valve into position. The click means the valve is
unlocked and the height can now be adjusted. No need to
adjust Valve height now. HydroClean adjusts after installation.
Tank sizes vary; lay J-tube along back of bottom of
tank, with Sliding Elbow in back right-hand corner,
as shown. Place Valve in tank to estimate J-tube
length needed.
Before attaching J-tube, adjust length by pulling
J-tube through Sliding Elbow if needed. For small
tanks, trim connection end carefully to fit. Push
J-tube onto bottom part of valve.
Position valve inside of tank making sure the
Rubber Washer is seated as shown.
Our Smart Nut should only be hand tightened
and should make 1-3 audible clicks to signal
it is tight. Wings are designed to bend if the nut
is overtightened, preventing leaks and cracking.
Lightly bump tab while turning the upper valve
body clockwise 1/4 turn. Then adjust the valve
up or down to the proper height.
Adjust the valve height so that the top of the cap is
even with the top of the tank. This height should
allow the final float adjustment to be achieved with
the Thumb Screw. Lock Valve into place by turning
Upper Body counterclockwise.
If the Overflow Tube has a cap, remove it and
discard before installing the bowl Refill Tube.
To install Refill Tube, attach Clip to top of Overflow
Tube. Trim Refill Tube to length to prevent kinking
and connect to Refill Tube Port.

NOTE:
Refill Tube must be positioned above the
overflow tube. DO NOT INSERT REFILL TUBE
DOWN THE OVERFLOW PIPE. This improper
installation violates the plumbing code and
could result in a leak.
If the building’s water supply was turned off, make
sure the Float Lock is engaged before attaching the
water supply to the tank.
DO NOT OVERTIGHTEN.
We recommend replacing
an old, rigid metal water supply line with a flexible,
braided supply line.
DO NOT USE PLUMBER’S PUTTY TO SEAL FITTINGS.
Turn on the water and run the bath tub water to
flush out and debris. When water is clear, disengage
Float Lock to fill tank.
If water was turned off at the toilet, disengage the
Float Lock and turn the on water supply to fill the
tank. Use the Thumb Screw to adjust the proper
water level inside the tank as indicated on the tank
or 1/2˝ to 1˝ below the Overflow Tube.

Slowly add water to the bowl until level no longer
rises. Wait 2 minutes for the excess water to runoff
down the drain.
Use a pencil to mark 1/8˝ below the water level in
the bowl, then flush the toilet. If the valve is still
filling the bowl after the water reaches the pencil
mark, you will need to adjust the Mini-Valve to
decrease the amount of water filling the bowl.
HydroValve ships with the Mini-Valve at the midway
open position. Turn counterclockwise to decrease
the amount of water filling the bowl, adjusting up or
down until the tank shuts off close to the same time
as water in the bowl reaches the pencil mark.
