TOILET TANK FILL VALVE INSTRUCTIONS 
E-Max
TM 
1.  Shut OFF water supply to 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. 
5. Place new fill valve inside tank hole. 
6.  Thread mounting nut onto fill valve shank and tighten nut. 
  Note:  DO NOT OVERTIGHTEN. Be sure to install fill valve in a 
    position that does not interfer with the trip lever operation. 
7.  Connect water supply to fill valve shank and hand tighten only. 
  Note: DO NOT OVERTIGHTEN. These are plastic parts. 
    Never use pipe dope on any water supply connection. 
8.  Attach refill tube to fill valve nipple and clip other end of refill  
  tube to the overflow pipe. 
9.  Turn water supply ON and check for leaks outside the tank. 
  Note: As water fills the tank, water is also directed into the 
    overflow tube via the refill tube. This additional flow 
    of water is critical to refilling your toilet’s bowl. Once the 
    water stops filling the tank, some residual drops of water 
    may drip from the fill valve. This is NORMAL as these 
    drops will subside. 
Depending on the manufacturing plant, you may have one 
or the two of following fill valves. 
You have chosen a TOTO
®
 product that is superior in quality 
and craftsmanship. Our toilet flushing systems are the  
best in the industry. To insure that your toilet is performing 
correctly, always flush the toilet with a full stroke of the  
trip lever to activate the flushing cycle. A full stroke will  
guarantee that you are flushing with the power of a TOTO
®
.
