While attempting to fix a dripping shower faucet, I first had to turn off the water using the built-in shutoff valve. Then I got out my shower faucet socket using the 29/32 & 31/32 combo socket. None seemed to be the right size. 29/32 was too small. 31/32 was too loose and slipped when tried to undo the valve. Could there be a 15/16 size? Please let me know. I then had to turn back on the valve. Now theres a small drip that I couldn't seem to stop. One drip every 3 sec. How do I stop it. It looks like I would need some sort of key to fit into a notch to tighten up the pack if there is one. Does anyone know?
