I got the replacement part from amazon with expedited shipping and everything is fine again. I could not figure out a temporary fix to prevent the water from draining so had to continually re-fill to prevent the pump from sucking air. I have an infinity edge with auto refill but if the pool gets too low overnight the basin drains faster than the auto fill can replenish. Might purchase a spare valve in a few years to keep on hand, I'd estimate life expectency to be less than 10 years so I have some time to think about it.
