about 2 years ago I had to replace the guts on one of our toilets. The toilet is an old one. To do this job I had to shut off the water supply, when the job was done I turned on the water but now the valve is leaking. It is a small drip but now i have a small bucket under it.
How can i stop this leak can it be done without changing the whole valve? Remember this valve is 50 years old.
