Running water in toilet

Brenda Linger
by Brenda Linger
We recently replaced a toilet due to a crack in the tank. Now, it seems that whenever I walk past it, the water flow cuts on for about 5 seconds. Does that mean it isn't level or am I looking at leaky pipes? Thanks

    Adjust the float, there's usually a screw to turn, take care to watch which way you turn, you want the float to go down.

    The flapper is not closing all the way. The chain on the flapper is probably too tight.

    I agree with both the above, also check the chain to make sure it isn't kinked.

    If it is the chain getting hung up, when you flush be sure to wiggle the flush handle until you hear it seal off. You can figure this out by doing this with top off to see if flapper is closing properly. A tip to save on water is to fill a 20 oz bottle of water and close tightly and put into tank. it will take place of how mush water you need to fill after each flush.

    If you are unsure of level remove the top and put a level on it to rule that out

    That happened to us recently. It turned out to be a bad ball cock, a.k.a. the FLAPPER That's the rubber thingy that plugs the hole so water won't keep running into the toilet. Just a tiny nick, piece of debris etc. can cause it to leak just enough to cause the water to turn on in the tank. A 2 second fix with a new ball cock took care of the problem.

    Wow, the same thing happened to me twice. I redid my bathrooms. two of them at different times. and each time the new toilets would start running, shut off then start again. I kept jiggling them and eventually they started running constantly so the contractor came out and found that the tank level was set too high and that would cause them to run. He fixed them by setting the level lower. There was nothing wrong with either of them.
