I have a super pet chew proof 26oz water bottle that the plastic washer that came with it has warped and the bottle now leaks all of the water out over night. The helpful person at Lowe's suggested I try rubber rings, they didn't work. He didn't know of anything in the store that would fit.I was wondering if anyone else has replaced this washer and with what? Thank you!

If there isn't any easy way to cut your own new one, I'd probably just get a new bottle, alas.

They probably sell rings that are equivalent to the one that warped, I would take the ring to the hardware store and find someone in the area where they sell plumbing stuff.
