Leaky Toilet shutoff valve....?

Question

The water shutoff valvue has a slow leak where the hose connects. Its right were the hose to the tank connects to the shutoff valve.....I also noticed when I close the shut off valve it doesnt stop the water completely. Does the whole setup need to be replaced, and if so, is it difficult? Or will just replacing the hose correct the leak?

I figured the constant running wasnt a huge deal if there was no leak because you leave the water on anyways, so there is always constant water pressure there.

Jeffrey S......you are correct. It is a leak from at the connection from the hose to the cut off valve.......the other prob is the cut off valve doesnt completly cut off the water. I didnt think that was a huge deal because the water stays on 24/7 all the time anyways.

Answer 1

This is quite common. If water is leaking on the floor from the hose, replace the hose with one of those user friendly flexible hoses called "toilet supply hoses" from Home Depot or your local hardware store. It could be the gasket but your hose is probably old and replacing it may save you a small flood. Your shutoff sounds like it needs to be rebuilt, but you as you mentioned, this is not critical because it is on all the time anyway. You can try buying the exact same shutoff, then shut off the main water supply, then take the shutoff apart (without removing it from the supply pipe) and replace the "guts" of the valve. The part where it attaches to the incoming supply is probably fine, so rebuilding the "guts" of the valve should work. Use Teflon tape when you connect the new supply hose and be sure to drain the water from the back of the tank with a cup and sponge before you remove the old supply hose.

Hard to tell exactly from your description, but I'm guessing the leak is only at the hose to cut-off valve, not a leak from the cut-off valve itself. If this is the case, there is no reason to change the cut-off valve. If tightening the hose hasn't fixed the leak, you can get a new hose from the hardware store and install it simply.

It's not a huge problem if your cut off valve leaks a little as long as it's not leaking out of the handle. These can be easy or tough to replace, depending on what type of connection has been made to the wall pipe.

Answer 3

After replacing hundreds of these I suggest that any cost of the mentioned fixtures is far less than the resource wasted.

I'd begin with a new shut off,,,inexpensive and easily installed, once the main line has been temporarily shut off. Then as long as it is, replace the line as well. I suspect at a cost of less than $10 for both.

Often the issue extends to how YOU might have threaded both, how tight, within reason you secured them, and this is so common you should be able to alievieate the poroblem by replacing,,,, as long as you consider cross threading and possibly threading metal components to plastic.

On an environmental note, Constant running is wasteful, and certainly damage to any flooring, or walls/molding that sponge up any leakage are wasteful in an after effect.

as for the actual leak replace the supply tube to the toilet (it's called a closet supply tube)and don't get the braided one with the rubber gaskets already made into it i've repaired thousands of dollars of damage caused by them.get the poly supply tube,toilet supply nut, 3/8" compression nut and 3/8" teflon ferrule.(ferrule goes tapered end into valve)if the valve has to be replaced it depends on what type of water lines your house is plumbed with to determine difficulty of replacement.try a new washer---turn off water to house and drain best as possible.open toilet supply valve all the way and remove stem by unscrewing packing nut (the one the valve stem comes out of)you have to turn handle and packing nut to completely unthread it.replace washer and re-assemble. good luck.(p.s. hold valve still with opposing wrench or pliers so as not to twist pipe in wall or floor.

Answer 5

I'M plumber : sound like just need to replace the gasket in both ends of the hoses,some times this get worn or not tide enough

Answer 8

Go to Home Depot and buy the whole kit, they don't cost that much and will probably save you more in water usage. Get a good one though, don't stop at the dollar store for one.
