Yeah then it definetly sounds like making a piston valve would be the way to go. Hopefully the tee won't cost you too much, what size are you gonna get?

Mine was $6.99 + employee discount (which took off 15%). Perks of working at a hardware store.

I might order off this site:

I'm not sure how reliable their fittings are as they don't carry 1 specific brand, its kind of like a you get what you get sort of thing. They do say however that all the fittings sold (or the ones sold in the page I linked above) are white schedule 40 fittings.
A 3" tee will cost $9.58 and that's where I came up with my $10 figure.

Just make sure it's NSF-pw. If its a DWV then it's not worth it for obvious reasons.
I found this on the lower portion of the page too-I don't know if you seen them or not.
"Can I use PVC pipe and fittings/valves for compressed air or gases?"
Although some people use PVC piping for compressed air or gases, we are not aware of any fittings manufacturer that recommends it and we highly recommend that you do NOT use plastic fittings with compressed air/gases. We believe it is dangerous and absolutely do not recommend it. Air is much more compressible than are liquids and could therefore cause a violent explosion.
Caution:
Do not use or test these PVC fittings with any liquids not recommended by the manufacturer. Do not use these PVC fittings with compressed air or gas systems. Modification of these fittings voids any warranty.

Yeah we seen 'em. In other words they say don't use with compressed gas because it will shrapnel violently when it explodes. If it is just pressurised water it wont shrpanel. (violently)

Key word- violently. I'd just search the stores gwoloshyn, it's a safe bet plus you don't pay shipping.

Yep, its pressure rated. It says sch40 nsf-pw. I get it from a local hardware store called McClendon's that specializes in plumbing.
