Channellock® pliers  

Fluidmaster® Toilet Fill Line Kit
Korky® Plus Premium Adjustable Flapper  
Needlenose pliers 

Mr. Mat saw my commercial blog on Blogger and called me to do some little plumbing work. He stated that the toilet was leaking on the inside and that his water bills was huge. Mr. Mat said that he tried to work the toilet and now there was water all over the floor. For this job the toilet flapper will be Korky® Plus Premium Adjustable Flapper because the client asked for this product. 

This post shows the twenty one steps to remove and replace a toilet fill valve, and toilet flapper.

Step 1:
Above fig.1 shows the toilet that is leaking all over the floor, upon inspection the flapper was deformed allowing water directly through the toilet and to the drain line. The change of the toilet fitting can save a huge amount in water bills. According to American Water Works Association a stuck/open flapper condition wastes 200 gallons per hour and for a 24 hour period that equals to 4800-gallons wasted.
Step 2:
Remove the toilet bowl top cover and carefully place it in a safe area. Watch out these toilet bowl covers are delicate and when they break they are difficult to replace. Fig.2 shows that you need to follow the toilet feed line and this will bring you to the stop valve. Fig.3 shows that the toilet stop valve will need to be shut off. This will prevent any water from going into the toilet bowl.

Step 3: Fig.4
shows the look inside the toilet bowl, all the way to the bottom is a large plastic round rubber piece that flap when the toilet lever is pulled. Pull the toilet lever and let all the water go down the drain. Notice that no water is coming into the bowl, if water starts to come in the bowl the stop valve is not completely closed. This flapper is attached at the flush lever through a spring clip. Use needle nose pliers to pull away the clip to remove the chain that is attached to a float.

Step 4:
Take the old flapper off the toilet fill tube, at the bottom there two mounting arm that hold the flapper, peel one side at a time until the flapper is loose. Dispose of the rubber flapper into the trash can.

Step 7: 
Now replace the new flapper by cutting off the ring with scissors. This toilet has mounting arms and the center ring is not needed. Place one side at a time then pull the metal chain to the toilet lever. Fig.7 shows a visual directions on how to place the new flapper.
Step 8:
Fig.8 shows to insert the new clip and chain from the new flapper to the flush lever arm. Notice there are several holes. Clip the chain to one of these hole. It take a few time to adjust the chain so that when the flush lever is pulled the flapper stays up and goes down with the water in the bowl.

Step 9:
The flapper is finished, but this job also needed the fill valve to be replaced. Now before the fill valve is removed, the fill valve line needs to be removed first. Fig.9 shows the feed line has been removed. If water starts coming out when you start to remove the toilet line turn off the stop valve.

Step 15: Fig.15 shows the water valve and the black rubber seal. Take the pieces apart, and remove the rubber piece from the ring. Use the ring on the bottom of the fill valve. If you are not sure look at the old fill valve. The larger white nut will be used to secure the fill valve from the bottom of the toilet bowl.

Step 21: Now turn on the water from the stop valve and refill the toilet bowl and check for leaks. Allow just a little water in the bowl and check to see if the fill valve is leaking, if it is, tightened the nut with the pliers. This job is finished.
