I don't think you're stupid in the least bit... I'm just curious as to what you're getting is all... I'm a big fan of the KISS method is all... Oh, and I'm a cheap bast@rd....

Not much, just some fittings and about five piece of pvc pipe.

AH! I get it... It's all those union/ball valves.....

and that 3" ball valve must have... I don't even want to think about it....

Ouch....
unions arn't cheap either...

Actually it is just a 2" ball valve but they all add up quick.
