Connecting valves to manifolds
I saw the earlier thread on pre-built vs. diy manifolds. At this point, I'd just as soon buy pre-built if I could find such a thing (which I haven't). I intend to use the existing valves, which have threaded connections, and as much of the existing manifolds as I can salvage.
My question is: Is it recommmended to install adapters and unions so that the valves can be removed for service, or do most installers permanently connect--thread the adapter into the valve and glue it to the pipe?
Thanks, again.
