- Why not use suft tubing (surgical tubing) with a lever that pinches it off?

- This has the advantage of not wasting the water when off.
- Instead if a blader you might be able to use a plunger that slides inside the
- tubing.
- I suppose if the bladder were bigger than the tube, you wouldn't need the
- lever.
- I hope you can come up with something that works!
