I went to turn the water off with the shut-off valve so that I could do some work on the toilet tank (replacing old and leaky fill valve) but the water won't shut off. I'm assuming that I'll need to replace the shut-off valve itself but could anything else be causing the problem? The funny thing is, the leaky fill valve that I wanted to replace has now stopped hissing and leaking and the tank seemingly fills fine. But of course the water can't be turned off completely.Just wanted to check make sure that there aren't anything else I should do or consider before I went off to replace the shut-off valve.Thanks
Youdont give much info here.Does the ballcock come back up after flushing, if it doesnt you can bend it gently upwards, so that the piece connected to it that stops off the water, works better.If its ok then best buy a new ballcock with the valve attached.The way these work is all to do with the floating ball at end of ballcock .When the ball is on top of the water , then the other end stops more water coming in.These are usually easy to sort out.
No. Very simply if the toilet shut-off valve doesn't stop the water flow, it is faulty and should be replaced. However, the shut-off valve is only used to service the toilet, and if your toilet is operating okay, don't mess with it. If you're not that ambitious, the next time you need to service the toilet would be an opportune time to change the valve. Good luck and God Bless!! Steve
If you are turning on that valve and it doesn't shut off the flow of water to the toilet, then the valve should be replaced. Now, if it's not leaking, you don't HAVE to replace the valve. But of course, if the toilet overflowed you wouldn't have any easy way of shutting off the water There are many, many choices in replacing valves. You have to determine which kind of valve you have - sweat on, male or female thread, or compression - size of pipe coming out of the wall - size of thread for the fill tube. Once you have that figured out, you do need to turn off the house water before you take the old valve off. One more choice: Spend the extra couple of bucks and get a 1/4 turn ball type valve.
the shut off valves are soldiered on or threaded on it depends on which 1 you got. it might be easier to get a valve that looks like yours and putting the guts out of the new 1 into the old 1. as long as you can shut the water off to the valve
