ok, i just got back from plumbing warehouse..i got the 2" flex pvc( 6ft for $15 )...i got all the parts except for one of the tee's that i need...so far, i have spent $160 on the plumbing alone!!!! actually, i got a hacksaw that was $15, so $145 total for parts....i am not sure where Anthony came up with building the manifold for under $20 LOL....every time i have built something with pvc and parts, it was well over $100...the ball valves alone can be $15-20 for a big one with union...i plan on starting tonight if i am not too tired when i get home from the gym...i may have a few pics later on!!!!!
