If you are fixing anything in a home or business...you are going to need to make a trip to Johnstone Supply.
Johnstone has a huge selection of mdse that you can use for any maint. repair. They sell hot water tanks, faucets, parts to almost any repair need, drains, toilet parts, air conditioner parts, light bulbs for industrial or any other size.
Johnstone has a huge catalog of items that they either carry or can order for you.
I just made a visit to their new store today. AWESOME nice store. They can order it for you if they dont have it.
