Oval type shut off valve for toilet leaks when open full

I just installed a new toilet in my basement bathroom. The previous owners had a toilet, but it was old and everything a too low to the ground. Anyways, the house is 1971 and has a "old" oval type shut off valve that had been closed for quite a while since the old toilet wouldn't stop running and we never used it, etc.

Got my new toilet hooked up and everything works great and I don't see any leaks, except the oval shutoff valve LEAKS pretty quick when I open it fully. This is the one of course that connects to the toilet to fill the tank.

I've got it really close to the closed position and so far there aren't any leaks and the toilet fills fairly quickly still after flushing, etc.

Is this ok or should it be in the fully OPEN position? Right now it seems to have stopped leaking, like I said, but I don't know if it's IDEAL to be mostly in the closed position.

Tighten the packing nut on the front of the valve. It would be the cover that is directly behind the shut off handle. If it is not leaking from there, then you need to tighten or change out the supply lines to the new toilet.

If it's one of those cheap shut-off valves and tightening the gland nut (as czizzi suggest) does not work, replace it. You can use a Shark bite valve. Quick and easy. Not soldering or threading necessary. I assume you have copper supply line.

I too would suggest replacing the valve. With a SharkBite shutoff valve, it should be a 10 minute project.

I hate those old multi-turn shutoff valves
