Make a note where your water level is then the tank is full. Replace the assembly that lets the water in with a Fluidmaster 400A fill valve, available at your local plumbing supply store.

Our WaterRidge toilet tank will not fill with water

This sounds like the float is getting stuck , while the toilet is trying to fill if you see the float ball that is attached to a arm that pivots , if you lift the float up it should turn the water flow off from trying to fill the tank , some problems that can stop this are the rubber seal that lifts up when you press the flush button to allow water to flush the bowl does not seal back in a position so that the tank can never fill , sometimes the float ball can get stuck which stops it from rising up with the water level and shutting off the water , but my best guess is that the rubber seal has started to perish or distort and needs to be replaced you can find this right at the bottom of the tank and it is directly connected to the flush button ,so if you inspect inside the water tank and press the flush button you will see that it opens up and lets water pour into the toilet bowl but if a tight seal can not be made water will never fill the tank

Toilet Flushing

Is your supply valve on below the toilet? Maybe the float inside the tank is stuck in the up position? Or else the float valve is stuck. Shut off the supply valve below the toilet tank. Take off the line going to the tank. Slowly open up the valve a little does water come out? If it does, I would replace the float assembly with a new one. If there is no water, then the problem is in the plumbing going to the supply valve in your house. Good luck and please rate my answer so I get points

After flushing, the toilet keeps running. However, if I turn off the water supply, and then turn back on, the toilet stops running until the next time it is flushed. Toilet makes a

It could be the type of flap you are using. I would suggest you try a different shaped flapper (a cone would work best) and if that doesn't do it, put a new kit into the unit, because it could be that the float system is sticking causing it to continue running.

What do I do to stop water from leaking from the tank, it refills itself several times, day or night? The toilet looks like a Sedona, although the shape of the tank differs a bit, the width is the same,...

Sounds like something in the floating device is bad so it doesn't shut off when filled. We just replaced our flush valve on ours because the toilet keep running.

Every time we flush the toilet it makes a screeching sound, like something is about to explode, any ideas on how to make it stop?

sounds like the valve is making the noise. You will need to replace it to stop the sound. The valve is the part of the stool that is located in the tank, the water supply connects to the bottom of it, and it lets the water refill the tank until the float turns it off.

I have a dual flush corona and there is a stream of water leaking into the bowl. It periodically has to continue to fill when it gets low. I have replaced the round seal inside the tank at the very bottom....

There should be a float inside the tank of the toilet. Be sure that when the tank fills that the float is not getting stuck, or not floating all the way up and not sealing the flush valve at the bottom of the tank.

The toilet keeps running constantly - the tube in the tank is overflowing and i can not get the dripping sound to stop. Anything i can do?

The noise is because your float in the toilet is set at too high of a level and it is overflowing and making noise.
Reset your float, to adjust the water level just below the overflow pipe...this should stop your noise.
If it does not correct the problem then you will have to replace the water control unit inside of the toilet tank.

What you hear is the washer vibrating against the ballcock seat. The reason it stops when you turn the water on is that you have lowered the pressure by opening a valve. You can go at this two ways. (1) you can lower the pressure by turning the angle stop located below the tank until the noise stops or, (2) you can shut off the stop and remove the three screws on top and cup your hand over the top and just crack the stop enough to flush out any trash that may be in there. After you do that pull the washer out of its holder and flip it over in its holder and reinstall the top and float. One of the two should do the trick. If not click on back and
replace the flush valve. Joe

I have a toto toilet that doesn't start to refill until a couple of minutes after I flush. Any ideas. Thanks.

Several ideas. Start to fill? Have you looked inside the tank to see what's going on? If it just filling very slowly, then you most likely have some calcuim build up inside your flush valve blocking some flow, if this is the case you will have to clean the flush valve. If your flush valve is staying up and the toilet is "running" unitil the float drops. The float (either the arm ballcock style, or newer fluidmaster) is rubbing on either the flush lever or side of the tank, and taking longer to drop to let the water start flowing. I

What is square box (float) attached to flush valve inside tank

The foam block does a few things: It helps with noise level, helps prevent condensation and also takes up space in the tank to lessen water usage with each flush.
Keep an eye on the outside of the tank and if you don't ever notice any moisture on the outside of the tank then I wouldn't worry about it all!!
