I'm having a problem with some part inside my toilet. My question: are all toilets universal? If I go to Home Depot will any kit work with my toilet? Hurry up because I need to take a dump.
That depends. Most of the porcelein parts are the same, but the insides can vary. If you get a completely new set of innards, you should have no trouble, but if you want to replace a specific part, be sure you get the part that matches the type of workings you already have. I have three bathrooms, I've done this a number of times.
The problem I'm having is the rod that screws into the floating ball does not screw into the other contraption anymore. I can push it in there but usually after a few flushes it will fall out.
You might just need a new floater assy. Threw screw in part is usually pretty universal. Its possible that the overflow (thats what the ball screws into) might be stripped where the ball screws into. If thats the case, youll need to replace that, which would involve draining and removing the upper tank. Pretty easy job. Just make sure you turn off the water (duh) and be careful about resecuring the tank to the bowl (if you tighten the bolts too much, you could crack the porceline).
Sounds like the threads for the float valve are worn out. You'll have to replace the float valve. This will require a bit of work, not much, but some. You shouldn't have to remove the tank (the top part of a toilet) for this. http://www.toiletology.com/replace.shtml
No, do not remove the upper tank. If the pole in the middle with the flapper valve is in good shape, you do not have to remove the upper tank. Just replace the float valve assembly as one unit (they're cheap). Much easier that way.
