Trevor and Cheri at http://www.theskylightguy.com/ have taken over
the manufactury of Delta Six parts for the Westys, and have just told
me that the water level senders have passed QA and are available for
sale.  They're in Canada.  Bus Depot in US will also have them
soon.  I see they're not on the website yet, but I'm sure you can get
details from info (at) skylightguy.com.

Yours,
David
