A working toilet all of a sudden won't fill back up. When I pour water into the tank, it will flush, but it doesn't refill.

You should replace your fill valve. They are cheap (around $10), and easy to replace. Visit your local hardware or plumbing shop. Instructions are on most packages. In the meantime, if you have a toilet full of nasty, just pour water right into the bowl, when it reaches a certain level it will flush. If it doesn't flush, you have a clog! Your flapper valve may also be the culprit, if you flush and the water just keeps running into the holding tank, the problem is the flapper! Also cheap and easy to replace. Whenever i have a problem I buy a toilet rebuild kit. They are about $20, and will work with most standard toilets. I hope this was helpful!

Replace the assembly. This is common in areas with high mineral content in water. You will be glad you did. Delay too long, you may find your toilet running while you are at work .

Usually seeping is from under the flapper. Replace flapper with one designed for that model. Avoid generic flappers.

Check the power source to toilet and all wiring conversed.

There could be several reasons why it won't refill. It could be the fill valve, which can be replaced with a standard fill valve located at any hardware store. The more likely reason is the stem inside the shut-off of the toilet has broken off inside the valve. This is very common when a valve is older and usually doesn't get shutoff. If this is the case, a new shut-off valve must be soldered on.

Hi!please kindly check your fill valve if it is working correctly.I thought the problem is in your fill valve.Kindly adjust the floater of your fill valve.

Hi keithn60...

I had the same problem one time with my toilet tank, the answer is to put some silicone on the seal washer between the take and bowl assembly and to use a level on the tank to tighten it just enough to be level and not leak.
Please take time to rate me

Lift the tank lid off, place it somewhere safe for a moment, and look at what happens: If you're talking about jiggling the handle to get the tank to start to fill with water, then it sounds like the chain or rope is out of adjustment. It can't be TOO TIGHT or the water will leak past your flapper (will cause your dripping noise, tank water level will leak down, causing constant refills), and it cant be TOO LOOSE or the toilet won't flush correctly. Since you didn't mention trouble flushing the toilet, I think that it may be a little too TIGHT. When you jiggle the flush lever-it is supposed to pull a chain or cable to open the flapper at the bottom of the tank. Flush the tank and watch what happens-all the way through to refilling the tank with water and shutting off the water refill valve-Does the flapper get stuck on the chain or something? It is supposed to fall back down to allow the tank to refill after flushing out your toilet. Does the chain look very loose? The dripping sound you described indicates that the flapper is not sealing 100%. The flapper is very easy to replace, you just have to get the adjustment set for when you flush the toilet how sensitive you need it. You amy have to play with it a little bit before you get the adjustment correct.

Hope this helps!

okay depending on the type of toilet ball **** (i know its a funny word, but it's really what its called.) you have one the most standard type is the long wire with the big ball on the end. you need to adjust this ball **** so it goes lower test it out, flush your toilett and wait till the water drains then when its supposed to come back up push down on the ball **** and youll see the water will start to fill, so then adjust the little screw on the fill valve (the other side of the floater where its attached)

you may need to shut off your water supply and drain your tank depending on how skilled you are,

pretty simple work, if you have questions feel free to ask.
