Our LX2610 has at least three drain plugs with I'm guessing copper crush washers. There is no mention of replacing them every time, which I what I tend to with a car. Am I asking for trouble if I anneal them and resuse them? I don't know what size they are at the moment, but by next time around I will, and will probably pick up some for future use. I can order some but may need to do a servicing before they arrive.
