With all the mechanical action that takes place in a toilet tank, it is not surprising that some of the internal parts will need replacement from time to time. If the toilet tank still works or did not work properly, it is time to replace the fill valve. It is not a difficult task, even if you do not have any plumbing experience.

Instructions
1 Cut off the water supply for the toilet and pull the chain to remove the water. It is also possible that at this time you want to clean all the lines and valves involved.
2 Remove the lid of the toilet tank. Using the sponge, remove more water still standing in the tank.
3 Loosen and remove the feed line from the bottom of the tank. Have your bucket ready to pick up the water that is standing in the old pipe or valve.
4 Remove the large retaining nut just above the power line at the bottom of the old unit, and remove the unit from the tank.
5 Clean the tank clean and dry, with the sponge before installing the new unit to remove any particles of grain or rust that could ruin the new seal or valve.
6 Set the new fill valve. Most new valves twist to adjust the height. You want to adjust to the highest point you can go without touching anything inside the tank. Now you just have to reinstall the new unit in the place of the old one. Make sure the float does not touch the sides or top of the tank or the ball valve on the bottom.
7 Install the overflow tube in the overflow tube. These usually only latch on top.
8 Install and tighten the unit retaining nut. Just tighten this nut enough to hold it - be careful not to break the porcelain. Wrap the threads on the end of the feed line of the Teflon tape unit and install the feed pipe and tighten. Do not over tighten this accessory as it is a plastic connection in most cases and can easily break.
9 Open the water again and pull the chain. If you do not discharge or refill correctly, you may have to adjust the height of the new fill valve by turning it higher or lower.
