Well I have called just about all the plumbing businesses within Vancouver that I could get to (without a car) and cannot find a 2" gate valve! I think I may give a 1.5" gate valve a try. I have two questions though...
1. I used the calculator on RC to figure out that my return pump will be putting out around 1600 GPH after head loss and elbows, ect.
I believe a 1.5" bulkhead is about 1600 GPH. It seems like if I reduce the drain down to 1.5" it may not handle the return pump very well or may be cutting it close. Does this make any sense?
2. Why are these so expensive! Is this normal?
