V SmithDeanna NassarKenneth Stevens


How do I fix running toilet bought all the new "guts" to change existing inside toilet and also metal hose from supply to toilet but now I'm afraid to do it. Know how to shut water off etc. Am also wondering if flusher handle outside toilet connected inside. Toilet to plastic arm to a chain has anything to do w it running. Retired RN n feel I should be capable of this. Don't want to hire a plumber HELP

    Running toilet is only the round plunger not meeting the whole you only need the rubber plunger and take the chain off and take it to Home Depot it’s about 10 dollers

    Will check all these solutions out today I think the water level may be too high. It's seems to go right up to top of the thin overflow tube so I will adjust the blk plastic tube for the float? Clockwise to bring water level down right?

    Tri to clean the flush valve not the fill valve were the water leaves the tank. Using one of those green sponges. If there is dirt there it may be keeping the flote from sealing allowing water to keep flowing.

    Lady in film talks too fast. It's not all that hard to do. Take a deep breath and go for it. Cut water flow from back, flush toilet. Replace ball first. Then place something under toilet to catch left over water when you disconnect the fill tube at base of toilet. Remove the float and put in new one. Replace fill tube to base of new float and tighten down. Connect chain from ball to flush handle. Place tube from fill to overflow tube. Turn on water from wall and check at base of tank for any leaks and tighten if needed. When water stops flowing in check how high is water on fill tube. Adjust float so water level is about 1/2 inch from top. Do a test flush to check level of water in tank when it fills. When you have it right, give a pat on your back and clean up.

    I've done the job before and the hardest part is if you replace the fill tube at the wall connection. Just leave it alone unless the tube itself springs a leak. I was one step away from having to replace the whole valve at wall. I lost my temper more than once in the process but I learned I could do it if I slowed down and took a little time.

    It is not a difficult task. Take a pic of current set up, make sure your new guts match the height of your old guts. Turn off the supply and flush holding handle down to drain all of the water. Use caution when tightening just go for hand tight. You should not need to replace supply line to fix running.
