Can't find replacement water heater drain valve washer.
It is a size that I can't find in any hardware store despite the manufacturer saying it should be easily available at most hardware stores.
17/32 X 13/64 X 1/8
The part is item #4 in the parts list
and I found more than one manufacturer that uses that size in more than one model of water heater but they don't sell them.
The manufacturer says they don't have it so I should just buy a new valve whenever I need a washer.
Is there some place that sell most sizes of washers? I checked Lowes, Home Depot and a plumbing supply store locally already and gave the dimensions and they say they have never seen anything that size.
