Fixing toilet, refill valve broke off, can't get nut unscrewed?

Question

My toilet would keep running so I bought a kit to replace everything inside the tank. I was trying to get the refill valve out (the one with that part where you lift it up enough and the water stops coming into the tank) and it broke. Now all I have is a little plastic ring at the bottom with the washer underneath, and then it's still connected on the outside of the tank to the water tube. I can't get a good enough grip to hold either one in place while I turn the other one, I've tried to cut through the plastic ring at the bottom to get it out so I can install the new refill valve, but I just can't get it out. We're down to 1 working toilet because I can't get the old refill valve out! HELP!

Answer 1

You could drill out the old fill tube.  You would need a good size drill bit to do this.  Your best bet would be to go buy what they call a unibit. It's a dill bit with a sizes on it. It start out small and incereases as you drill through.

Answer 2

snap it off from the inside

Answer 3

The whole toilet is held to the floor by two tiny 1/4 bolts.  Unscrew them and take them off and remove the whole toilet, take it out of the house and gently get it into the light so you can see exactly what you're doing.  Don't use a lot force or you'll wind up cracking the ceramic.  Hacksaw or dremmel it off and get a new seal for the floor and reinstall it.

Answer 4

You need to remove the water closet (the tank on the back of the toilet). This is usually done by removing two bolts through its bottom.

Once the tank is off you should be able to turn it over the see the nut on the bottom of the tank. Now take a hack saw and cut the tube/nut assembly off flush to the bottom of the tank. All of these parts are usually plastic so it shouldn't be that tough. Be careful not to hit the tank because it ceramic and can shatter.

Hack saws are cheap and available at most big box stores that have a tool section.

Answer 5

You can try a sharp wood chiesel to chip away at it...if it has a plastic ring nut underneath. If you can't get the old assembly off the supply line you may have to replace that also.

You can also try a sawzall and cut flush  the underside between the ring nut and toilet tank (room allowing).
