I have a toilet that adds water to the tank usually late at night to early morning about every hour. I replaced everything in the tank If I shut the valve to the toilet and drain the tank it will eventually refill.I do not see any leakage Could the valve be the problem?

Just when I thought your post may be the first one to finally prove presence of Ghosts... :D

Lakin7944, what you have is a very common problem: Your flopper slowly leaks water into your toilet bowl. Once the water lever inside the tank reaches certain level - the fill valve automatically refills.

Solution: close incoming water to the toilet. Flush. Remove flopper. Take it with you to Home Depot. Buy exactly same flopper. Inspect the new flopper for unwanted warps and imperfections. (... yes, not all new floppers are perfectly straight ). Otherwise, flopper will leak and you will have to go through this process one more time. Reinstall. Turn water back on.

Usually, you cannot hear the water leaking into your bowl. You hear the refilling sound at night when noise pollution is down and you hear every sound in your house. The refilling actually happens during daytime too...

You said "If I shut the valve to the toilet and drain the tank it will eventually refill." and this will not happen with just a bad flapper. If you close the stop and the tank refills anyway there is some other issue happening here. This part I think is a partially closed stop under the tank, its 99% stopped.

Ballengerb1: Yes, the angle stop ( valve under toilet ) is not shutting all the way too. It should be (probably) replaced too. But the core of his problem is the constantly refiling toilet. I think he still should proceed as I suggested in post #2.

Thank you for pointing this out...

I agree that's why I said it was not just a bad flapper. I hear folks calling this a ghost flush but it really is not a flush at all, its just the tank fill valve opening to replace the water that leaked past the flapper.

I would like to put my two cents also, I have installed a few of these pumps for myself and my friends for the last few years and we have no problem, the only thing I will add if the sensors are not installed properly will give some problems, attach are the pictures the one I have installed in my house in 2004, Thanks.

I have a suggestion, to make sure that the new flapper valve that you install is holding water add several drops of blue food dye to the water in the tank and let it sit for several hours, if you don't see any blue in the bowl the flapper is doing it's job.

This will not work of course if you have one of the blue things in your tank that makes the water blue all the time.

Good point, letmetellu...

If you have one of those "blue things" inside your tank - remove it. It makes flopper too sleek making bad sealing connection.

I put the food color in and it is not leaking into the bowl. Is the angle valve the water supply valve?

Yes The angle valve is the water supply valve to ballcock, to check the angle valve for leaks close it completely flush the toilet see if water is flowing through the ballcock to the tank if not then the valve is OK and works fine,Thanks.
