Roller & Hose Clamp
For your convenience, the roller clamp
and hose clamps are pre-assembled to the
refill hose. Attach one end of hose to refill
clip and slide clip to right side of overflow
pipe. Attach other end of hose to nipple on
fill valve with a slight arching (see picture
to the left). Cut tube if necessary. Squeeze
tabs of hose clamp and move clamp to
end of hose, over the fill valve nipple, then
release tabs. Do not shove refill tube down
overflow pipe. This will cause water loss.

Simulate a leak by
slightly lifting flapper

400LS WATER-SAVING FEATURES
Prevents wasteful refills in leaky tanks.
The Leak Sentry
If there is a tank leak, the float cup will not drop to refill the tank until the tank lever is
pushed. On the first flush attempt, the valve will simply refill the empty tank; only then
will you receive a complete flush. This will continue to occur until the tank leak is fixed.
The Adjustable Refill allows you to adjust the amount of water going into the bowl,
eliminating water waste due to the bowl being overfilled.

6.
Water-Saving Feature: Roller Clamp
Check bowl water level by flushing toilet. If bowl appears to be full but continues to
fill, the valve may be overfilling the bowl causing excess water to siphon down the
trapway. Adjust amount of water going down into the bowl as follows: Fill the bowl
with a gallon of water. Wait 3 minutes until the bowl water level recedes down and
stops. With a pencil, draw a line at the top of the water level in bowl. Now flush the
toilet. If the valve is still filling and the water is up to the line in the bowl, then the
amount of water going into the bowl is too high and needs to be adjusted. Adjust
the refill by turning the roller clamp with thumb to the next lower number. Flush
the toilet; adjust until water level in bowl is at the pencil mark when the fill valve
shuts off. If valve shuts off and bowl is not full, adjust by turning the roller clamp
to a higher number. Repeat until water in bowl is up to line. "O" on roller clamp
equals no refill to bowl.
