Kids Bathroom Toilet No Water After Flushing

Hello All. Got a problem with my kids' bathroom toilet. After they flush, no water fills up the tank. I have to remove the lid and sorta tug on the chain that goes to the float to release the float. Then the float drops and water begins to fill the tank.

There's two chains, one going to the float and the other going to the flapper. I've attached a picture showing the part I'm referring to that keeps getting stuck in the up position and not dropping down when the kids flush the toilet.

Is it just a matter of replacing the fill valve? Or is my problem elsewhere? Thank you all.

 

Yes.

Usually when you replace a fill valve, you usually replace the supply line. You consider whether the stop valve should be replaced, while you are at it.

 

I cannot picture a chain that goes to the fill valve???

 

That is a Fluidmaster fill valve and is what I currently use. A couple things I've learned ........ Be aware the "top" of the unit disconnects from the stationary pipe that is connected to the tank & supply line.
In the middle of the pipe notice the plastic "keeper" ring that holds the two pcs. together. You just move the keeper ring up and the top portion with the moveable float will pull / slide right off. I just change the top of my units ... only takes a couple minutes.
Also be aware they have several different units ... depending if you have a restricted flow toilet i.e. the 1.28 gpm toilet or the older 3.5 gallon tank units.
The 400CR Fluidmaster is for the older tanks (3.5).
There are also multiple YouTubes on how to clean these valves.

 

Thanks for the explanation

 

There's a chain that goes on the bottom of the stop valve.

 

How about a photo of that chain that is not going to the flapper or flush valve? If you have a second chain in the tank, somebody added it as a non-standard thing, probably working around a problem. New fill valve would be worthwhile. Korky 528MP has an adjustable refill. https://www.homedepot.com/p/Fluidma...2-in-Flapper-Repair-Kit-402CARHRP14/206825432 includes a fill valve with an adjustable refill plus a 2-inch flapper. There is a similar kit for 3-inch flappers.

Adjustable refill lets you adjust so the refill maxes out just when the fill valve shuts off.



Stop valve is the shut-off valve at the wall.

EDIT: good call on the Leak Sentry!

 

Does the float actually get stuck in the up position? Inside of that top portion, there's a seal. Depending on your water, that seal might get stiff, and not allow the lever arm to move easily. The seal is a few bucks, and available lots of places.
