6) Flush the water supply line for a few seconds to
remove any debris that may enter the new fill valve. (For
new home constructions and/or additions, flush the
water supply line for more than a minute to help
remove any residual PVC adhesives, solder flux, and/ or
pipe sealants that were used for the new plumbing.)
Connect the water supply line to the fill valve threads as
seen at the bottom of toilet tank (see Illustration 6).
Tighten this connection finger tight.
CAUTION: Avoid using a wrench to tighten the con-
nection as you may damage the plastic threads and/or
cause the fill valve to rotate inside the tank.
NOTE: The water supply pressure should be 20 to 80
psi static.
7) Flush toilet a few times to check for issues and leaks.
Make sure NO WATER LEAK on bowl and tank.
8) Install the toilet tank lid onto the toilet tank top.
9) Install the toilet seat onto the toilet bowl using the
mounting hardware in the toilet seat box. Place seat
onto bowl and rotate the hinge down. Position seat
stoppers under the seat hinge. Insert bolt into seat
hinge and through the toilet bowl. Install plastic nut
onto bolt from underneath. Tighten the bolt securely.
Install the seat bolt caps.
NOTE: Tighten the seat bolt until the hinge is secure.
The seat and lid will have slight side to side movement,
which is normal. This freedom of movement allows the
seat to SoftClose® without binding.
1) Shut off the water supply to the toilet.
2) Flush toilet and remove remaining water from tank with a sponge.
3) Remove the water supply connection at the fill valve.
4) Remove old fill valve and use damp sponge to clean hole in tank.

NOTE: Do not over-tighten. Be sure to install fill valve in a position that does not
interfere with the trip lever operation.

water supply connection.
