Toilet Unscrew Lock Nut

I am trying to replace the valves inside the toilet tank.

Toilet unscrew lock nut.

If the nuts don t have wings lock a pair of locking pliers around each one in turn. This time i cannot remove the two plastic nuts under the tank holding the metal intake tube to the tank and the valve. Empty the bucket and place it underneath the water supply line. Another great tool i have found that is made by irwin tools is there original locking wrench.

Hold the bolt steady while you turn the nut counterclockwise. Some nuts have wings that you can grasp with your fingers. Step 3 spray penetrating lubricant in the threads of the plastic bolt if the nut does not unthread easily. Grip the top of one of the bolts with adjustable pliers then fit an adjustable wrench around the nut.

I have done this before and always seem to have a problem. Once it begins turning release. Try a 6 point wrench or socket on your seized nut bolt. Try and avoid 12 point wrenches and sockets as they likely to slip and strip the bolt head.

Works great for kitchen sink holding nuts lav faucets. If you can t grip the nuts with the wrench use a pair of pliers. Eventually and in an effort to save money some of the companies started shipping these ballcocks with a white metal nickel composite lock nut and coupling nut. Shut the water supply off for the toilet where you will be removing the lock nuts.

Start by rocking the bolt by tightening then loosing this may be all you need to break through the rust. Use a pair of pliers to just loosen the coupling nut. Don t twist the screwdriver until the plastic cools it ll then snap right off. Heat the tip of an old screwdriver and it ll split the nut when it melts through to the shank.

Hold a hacksaw blade up to the nut where it meets the underside of the bowl. Turn the handle on the supply valve all the way to the right to cut the water supply. Then finish loosening the nut with your fingers. Loosen the nuts with an adjustable wrench.

While turning these stabilize the bolt from above with a screwdriver. When you unscrew the screw the pliers will hit against the toilet bowl and prevent the nut from turning and it will loosen. I have tried every wrench i have crescent plumbers and locking pliers and now the nuts won t come off and the tube and valve are moving instead when i. Cut off the stuck bolts if you cannot remove the screws.

Locate the coupling nut on the underside of the toilet tank. To locate the supply valve follow the water supply line or hose from the underside of the tank to where it meets the supply valve at the wall. Place the plastic nuts in a safe location and pull up on the back of the toilet s seat.
