  1. Turn off water supply valve -> Flush -> Drain Tank
  2. Detach water supply line from tank (place a towel under supply-line for leakage)
  3. Remove just the nuts that connect tank to base (Tip: leave bolts in place, it saves a step when reconnecting the tank)
  4. Remove tank from base
  5. Remove tank seal at base (replace it if it is damaged or badly worn, do not defer this suggestion)
  6. Unscrew large nut at base of toilet tank -> Remove and discard old valve
  7. Remove old toilet lever (Unscrew lever retaining nut and remove old lever assembly)
  8. Remove stem valve nut -> Remove stem cap from Select A Flush valve kit and slide apart
  9. Remove stem valve nut and install new valve
  10. TIP: push down on valve stem inside tank while re-attaching nut -> Nut must be very tight to ensure a proper seal
  11. Replace tank seal
  12. Re-attach tank to base making sure to push down slightly on tank while tightening bolts for level snug fit -> TIP: use caution not to over tighten these nuts as tank may crack, you can always tighten them further if you detect a leak. You can also use a carpenter’s level for accuracy
  13. Slide the valve together
  14. Place entire component over the installed stem
  15. Install stem cap
  16. Disassemble new flush lever (Factory default is for left handed toilets, for right handed toilets see next step)
  17. IF right-handed toilet: Transfer lever arm assembly from the left to the right plate by unscrewing lever arm assembly on the left plate and screwing it on the right plate
  18. Place lever assembly through tank -> Re-attach seal and nut -> Tighten nut while applying pressure to back plate to ensure a tight fight
  19. Attach handle, cam, and nut -> Note: the cam always slopes down toward the inside of the tank
  20. If desired: add flush direction decal to front of tank behind the flush handle
  21. Loosen screw on lever extension to rotate arm in line-up with chain strap and re-tighten screw
  22. Adjust strap tension to ensure chain is slightly slack -> Note: if the strap is too tight it will only allow a full flush and can cause the valve to leak
  23. Rotate flush handle to the “rinse” position and hold -> While holding, check that the upper float lifts until the edge of seal is 1/8″ short of touching ears
  24. Reinstall water fill tube
  25. Reattach water supply line and turn it on -> Check for leaks!
  26. If needed, adjust water level (float valve) until 3 successful “rinse” flushes are obtained

Congratulations!
