I'm still new to piston valves as well, but i fell i may be able to help, so i'll voice my opinion. I'm not too sure about what size pipe will give you the best performance, so i'll leave that for someone else (sorry!) but what i did to get my barrel through my reducer (in your case a tee) in my pis...

Hmm thats a good idea. maybe i'll re-wire some of the circuitry for just 2 battery's. thanks for the tip i believe i have enough knowledge on piston valves, I've been researching some designs and i think i have a design that would work. I'm just really stumped on what to use for a piston. does anyon...

I'll definately try finding that leak tomorrow, and I should, with luck, be able to seal it up one way or another as for modding the valve, thats out of the question because this is my dads valve, and he may nee...
