How to Install a Fluidmaster Toilet Repair Kit

Almost all of the common toilet problems can be fixed by installing a Fluidmaster repair kit that you can get from your nearest home depot or hardware store. These issues can include, but not limited to:

  • Leaks from the tank into the toilet bowl due to a faulty flapper valve
  • Leaks from the rubber gasket between the tank and the bowl
  • Leaks from the bottom of the tank due to corroded bolts
  • Fill valve refilling the tank every few minutes
  • Toilet lever not flushing properly
  • Toilet that constantly runs
  • Leaks from a worn out flush valve gasket
  • Leaks from the tank’s supply line gasket

Now, do you want to know how to install this repair kit? Here are the steps:

1. Secure the tools needed for the installation, including a pipe wrench, pair of pliers, bucket, sponge, pair of scissors, a bucket and a hand saw.

2. Familiarize yourself with the repair kit’s contents, check out the instructions sheet and then assemble the necessary hand tools. As you will see, the kit comes with a new flush valve assembly with adjustable flapper valve, fill valve assembly, rubber fill tube, flush lever, new gaskets, and new tank bolts with nuts and washers.

3. Turn the toilet’s water supply off. Then, remove the tank lid and flush the toilet to drain out most of the water. You can remove the rest of the water using the sponge and bucket.

4. Pull off the old rubber fill tube from the flush and fill valve and detach the flush chain from the tank lever and the flapper valve. Unscrew the plastic nut that secures the flush handle and lever.

5. Move to the lower-left bottom of the tank to loosen the coupling nut securing the water supply line to the threaded shank on the fill valve. Then, unscrew the lock nut on the bottom of the fill valve and pull it out from the inside of the tank. You should also loosen the nuts on the bolts located on the underside of the toilet bowl using a crescent wrench or pliers. Carefully lift the tank off the toilet to be rested on top of the lid.

6. Pull off the rubber gasket from the bottom of the flush valve, and then push the old tank bolts out and unscrew the plastic flush valve collar nut to lift flush valve out. Locate the white coupling nut, white lock nut and black shank/cone washer that come grouped together on the white fill hose angle adapter, and separate then from each other and lay them aside.

7. Push the larger shank washer onto the threaded bottom of the new fill valve with the tapered side facing down, and then push one end of the new rubber fill tube onto the plastic nipple near the top of the fill valve. Place the new fill valve from the repair kit with the shank washer and rubber fill hose that is attached into the rear left corner of the tank. Make sure you secure new fill valve in place with the white plastic lock nut.

8. Finding the new flush valve assembly, remove the new rubber gasket, plastic collar nut and the cardboard shipping ring on the rubber flapper. Make sure you cut the overflow pipe to the correct length, and then insert the new flush valve into the center of the tank, securing it in place with the white plastic collar nut.

9. Slide the new rubber gasket over the flush valve with the tapered side facing towards you, and then lift the tank and carefully place it back on top of the toilet. Place the rubber washers inside the tank over the bolt holes and insert the new tank bolts through the rubber washers. Tighten everything up just enough not to crack porcelain parts.

All you have to do after completing these steps is to see if there are no leaks in any area of your toilet.
