hello

i just bought a home and the main water line wasn't the best, it wasn't leaking but now it is starting to leak right under to shut off. which is rusted and there is a consistant drip...

i know i have to fix ASAP, BUT the plumber's i 've called cant come out till next week and i would like to fix but i dont have the knowledge...is there a spray to fix temporary.

any help would be great.

thank you
