..rumor has it that they pressure test PVC to 600 psi but PVC also must be wrapped in celophane (old plastic bages) because it becomes brittle if exposed to the sun ... if your rich, you can use chrome/olly or some other welder's dream material
Pressure relief valve(s)
light weight metal, composite, or even Hi pressure P.V.C. tubing and unions,
length determined by your layout
If you use PVC Elbows 4ways & tees in your design, you'll need assembly jigs
Plugs (to partition the tank)
celophane of the recycled kind ( to wrap the frame)
