Thanks guys, for all the tips!

I do have the drain plug installed.

Always use teflon tape! Good stuff. Almost as important in life as duct tape

If it is the same valve, I don't know how it is working. The row of vents around the male threaded end suck air and release water if you try to prime the pump and line. If you block the vents, it might work. Did you block the vents?

Thanks a bunch, Perry. I'll give the guys at Hooked on Kayaks a call, or go by there. I'd like to check them out anyway. I have a drybag for the battery, but I wanted to try the switch close to the pump, for ease of use.
I have a nice solid bubble of goop around the switch, so I think I'll see how it goes as an experiment. What the heck!

Great help from all of you guys. Thanks again
