Some of these toilet issues include the following: 1. water leaking from the tank into the bowl due to a faulty flapper valve, 2. a water leak from the rubber gasket between the tank & bowl, 3. water leaking out of the bottom of the tank due to corroded tank bolts, 4. the fill valve refills the tank every few minutes, 5. the toilet lever won't flush properly, 6. a constantly running toilet, 7. a water leak from a worn out flush valve gasket, 8. or a water leak from the tank's supply line gasket.

This toilet also had a slow leak from the toilet water supply valve, so I bought a new one for about $5.

The tools needed to install this Fluidmaster kit include a pipe wrench, pliers, scissors, a bucket, a sponge, and a hand saw.

I twisted off the old water supply valve with the pliers and pulled it out from the supply pipe. The gasket and rubber o-ring on the old valve had deteriorated and was falling apart, which led to the slow water leak. Rather than having to remove the old welded on valve body, I just inserted the new valve innards and handle into the old valve body. I tightened the valve to just past hand tight. To help prevent leaks, you can wrap a small amount of Teflon tape or "plumber's" tape around the threads.

Again, only tighten the water supply pipe's coupling nut to just past hand tight to secure it to the bottom of the fill valve. If the connection has a slow leak after you turn the water back on, you can carefully tighten it further with the pliers or pipe wrench.

Almost done! Insert the end of the flush lever into the hole on the front of the toilet tank until the flush handle fits securely in place. Thread on the tank lever nut and tighten it by hand. Check that the flush handle and lever rotate freely.

Attach the flapper chain or "linkage" to the hole on the tank lever that provides the best lifting action of the flapper valve and still has a bit of slack. You may need to adjust the chain after turning on the water for the best flushing performance. The excess on the chain may also need to be cut off to prevent it from getting stuck between the flapper and the flush valve body.

Clip on the white plastic fill tube "angle adapter" to the black overflow pipe on the flush valve. Push the other end of the black rubber fill tube on to the white plastic nipple on top of the angle adapter.

Allow the toilet tank to fill with water and then flush it to see how the new system performs. If you're lucky, nothing will need to be adjusted. Check for any water leaks or accumulated water under the toilet for at least the next few days.

The flush volume can be adjusted by rotating the red flapper valve to anywhere between "9" (Max) and "1" (Min). The water level setting can also be adjusted by rotating the small plastic "water level adjustment rod" attached to the side of the fill valve.

I'd recommend placing some newspaper under the toilet tank and toilet water supply valve and leaving it there for the next few days. The newspaper will help you spot any slow water leaks that will leave water damage marks and ink runs on the newspaper but may dry up before you can notice the actual leak.
