Repair American Standard Cadet 3 commode losing water
Color: Multicolor
I have an American Standard Cadet 3 commode. The past month or so it has been slowly losing water between flushes. The water level will drop about an inch then it will refill. Since there was no water on the floor I determined that it must be the flush valve seal. I checked Home Depot and Lowes and could not find the right parts. On Amazon I found the appropriate flush valve assembly. Since replacing the flush valve requires taking the tank off, I also had to purchase the tank/bowl coupling kit. American Standard 738921-100.0070A 3-Inch Flush Valve Assembly American Standard 7301021-0070A Tank to Bowl Coupling Kit Total cost for both parts together was around $20. Both parts were shipped quickly. The flush valve kit did not have instructions (I like instructions). The coupling kit had some instructions. I checked on YouTube and found several videos but none that were pertinent. >> Here’s what I did to change the flush assembly. 1) Turned off the water. 2) Flushed to get most of the water out of the tank. 3) Used a rag to get the rest of the water out of the tank. 4) Unhooked the water line where it connects to the tank. 5) Used a tool that came with the coupling kit (it looks like a metal tube). I used it to unscrew the tank from the bowl. One end of the pipe looks like the end of a socket. It just fits over the bolt on to the nut. It has a hole in the pipe that you could use to slip a screw driver through for more leverage. I was able to just unscrew the bolt with my hand. I did not have to use a screwdriver to hold the bolt on the inside of the tank but could see where some people might have to. I unscrewed the nuts on each side of the bottom of the tank. 6) I then lifted the tank of the bowl and laid it on its side on a rug on the counter. 7) In order to remove the two tank bolt and rubber inserts, I used wire cutter to trim off the flanged tips of the rubber inserts. Once I did this they easily pushed through the holes. 8) I was able to hand unthread the large plastic nut that held the flush valve to the tank. 9) I removed the old flush valve. 10) Then I cleaned around where the flush valve and bolts go through the bottom of the tank. I also cleaned where the flush valve sits on backside of the bowl. 11) I then removed the plastic nut on the new flush valve and left the gasket on the valve. I put the valve through the hole in the bottom of the tank. (The gasket sits in between the bottom of the tank and the bottom of the flush valve.) Then I attached the plastic nut. I positioned the flush valve the way I wanted to sit inside the tank. I then hand-tightened the nut. I did not have anything large enough to get around the nut so I used the handle of some large channel lock pliers. The handles had rubber on them and I just them to get a little leverage to tighten it a half turn. Since everything is plastic you basically don't want to over tighten anything. 12) Then I took the 2 black bolt rubber inserts and stuck then through the screw holes inside of the tank at the bottom. Then from the inside of the tank I pushed the bolts through the rubber inserts. Note: You have to put the inserts through the tank before you put the bolts through them. 13) Next I put the large green hard rubber gasket/seat over the flush valve large white nut. The inside of the gasket is the same shape as the large nut. It should fit snugly unto the nut. 14) I then placed the tank unto the bowl. As I placed the tank on the bowl, I watched to make sure that my bolts & rubber inserts and the green flush valve gasket fit into the appropriate openings on the back of the bowl. 15) I then attached the water line to the bottom of the tank and hand tightened it. 16) Next I put the nuts on the bolts that anchor the tank to the bowl. Then I used the provided tool (metal tube) to hand tighten them. I used a level to make sure the tank was reasonably level. The tank sits on the rubber gaskets and not directly on the bowl. That means that once the nuts are tight that they is still some give with you push on the tank. Over tightening can cause damage to your tank. 17) I attached the flap chain to the tank flush handle. 18) I turned on the water and checked for leaks. As long as you purchase both items (see above), changing out the flush valve is a relatively simple process. Everything that was provided in the two kits was exactly the same as the factory original parts that came with the Cadet 3. Both kits were in packaging that appeared to be original "American Standard" parts. I really did not have to use any tools. Everything was hand loosened and hand tightened. You can create a lot of problems if you use tools and over tighten. Hand tighten then check for leaks. The whole process was under 30 minutes. I am happy with my purchase. The downside is it appears that I have not completely resolved my issue. It seems that I may be still losing a little water. Since there is not an obvious leak, the only two potential places for the water to be seeping is the flapper or the seal under the flush valve. If it continues, I might have to remove the tank and try to tighten the flush valves large white nut. ... show more

Fixed reasonably easily and saved cost of replacement
Color: Multicolor
This is a pretty good piece. It seems our Toilet was installed wrongly with the tank. Gasket was bit tilted and was causing water to leak very slowly. However, this leak was accelerating. Found some YT videos that suggested to use this to fix. I am reasonably hands on person as DIYer and ordered this. Pretty simple steps to change. --- Number of Helping Hands Well, you alone can certainly do it - make sure you have partner. It is not because it is heavy - but just you might be working in the small places to lift tank. --- Steps to Replace 1. Shut off inlet water valve 2. Clean tank with sponge or old clothes (cotton :-) ) 3. Use bucket under the side of tank where water inlet is - and open the inlet with plumbing wrench or joint plier 4. Open screws that joins tank and the seat. You may use shaft that comes with the set (right side in the picture) to hold nuts at the bottom of seat. 5. Remove tank 6. Replace components and just follow in the reverse direction! ---Suggestion Please screw only by hand initially. And then later - take turn with each nuts after every turn. Don't tighten one side before going to the next. Tank will be tilted if you do so and will risk leaking! ... show more
