A toilet that is not working creates havoc in the household, and if the toilet runs constantly or leaks, it will increase your water bill significantly. If your toilet runs constantly, leaks or will not flush properly, the problem could be a faulty fill valve or toilet pump. Restore order to your household and save money by replacing the toilet pump yourself.
Turn off the water supply to the toilet. Follow the hose attached to the bottom of the toilet tank to the cut-off valve. Turn this valve clockwise to turn off the water. Empty the tank by flushing the toilet, then dry out the toilet tank using old towels or a sponge. Place a bucket under the toilet tank to catch any water that is still in the tank.
Unscrew the nut holding the hose to the bottom of the tank with vice grips or channel locks.
Remove the nut screwed on to the toilet pump. This is under the toilet tank. After you loosen this nut, you may need to hold the toilet pump with one hand while removing the nut with the other because the toilet pump may turn with the nut.
Remove the clip attached to the refill tube from the overflow pipe. Remove the toilet pump from the toilet tank.
Attach the refill tube that came with your replacement toilet pump to the new toilet pump. Slide one end of the refill tube over the nipple on the toilet pump to cover the nipple completely. Attach the angle adapter to the other end of the refill tube.
Place one of the shank washers that came with your replacement toilet pump on the threaded shank of the new toilet pump. Place the threaded shank into the hole in the bottom of the toilet tank.
Fit the other shank washer over the threaded shank and push the washer firmly against the toilet tank.
Replace the nut on the threaded shank of the toilet pump and tighten fully.
Clip the refill tube to the overflow pipe using the angle attachment provided.
Screw the water supply hose tightly onto the threaded shank. Turn the water supply back on and check for leaks. If water leaks from around the new toilet pump, check to make sure both shank washers are firmly in place and tighten both nuts fully.
