I'm about to plan my first homemade water blaster. You can see the plan here.
Still, there are some technical questions unsolved.
- I'd like to use a typical soft-drink-bottle as a water tank. This idea has at least two advantages: The bottles can be replaced quickly and cheap and I can use different sizes of water tanks. I want to cut a hole in the screwtop of a bottle and glue it on the place where the water tank is supposed to be.
Now here's the question:
As I pump water from the WT to the PT, I suppose a low pressure inside the water tank, that would deform the bottle. What can I do?
My attempt was to apply a third check walve near the water tank (the one to the very right on my plan), but I think this solution is suboptimal. - As a pump, I thought of using a bike pump with a small adaption (so that it is not sucking air from the open side.
Would it work?
