Where can I find a decent gate valve? (No metal)

In this area, both Home Depot and Lowes carry all-plastic valves. They are
designed for plumbing systems; consequently they will hook directly to only the
standard PVC or ABS tubing sizes. There is one set of sizes for cold water lines
and another for hot water lines, which gives you some flexibility in hooking it
to your pump.
