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 connection 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.
