Are you using the pump to pump beer?!?

Not that it wouldn't work, but sanitation must be a bugger!

: Uh, I broke it I had a hunch that the dynamics would change once pressure
: was added to the system... I made that verticle dowel a little half-assed
: and it snapped after about the third gallon. I emptied about 3 gallons in
: 1.5 minutes. It looks like a little over one cup leaked out the front of
: the pump onto the floor. I'm not discouraged.

: Besides the other enhancements I already mentioned, I would try to take as
: much pressure off the system as I could by reducing the size of the
: cylinder or increasing the size of the valves and hoses. Rev 2 will
: (eventually) be two small cylinders. Two makes sense for the following
: reason: currently only 50% of the hose resources are being utilized; one
: hose always stands idle while the other is working. Two pumps would
: utilize more of the resource since neither hose would stand idle... it
: follows that the system would be less strained under that arrangement. My
: intuition tells me to avoid using valves and hoses much larger than
: .75" dia - could be wrong.

: The teeter moved really slowly sucking all that water into the 3"
: cylinder; I think I would prefer a more aggressive teeter. I'll make that
: failure point different as well. My single kayak will eventually
: have a homemade footpump in it but don't hold your breath.
