I'm trying to construct a simple ("simple") system to distribute water around the barnyard using PEX. Except...there are a mulltiplicity of thread sizes and types. GHT (garden hose thread) male and female. 3/4" NPT (again M & F), 1" NPT (M & F), PEX (1/2", 3/4", 1"). >>>

5/ Dropped $500 on PEX, ball valves, brass T connectors, sharkbite connectors, cast iron sow water bowls...

6/ starting at the yard hydrant (faucet), we are in GHT (garden hose thread): * 3' length of hose * adjustable pressure regulator * GHT / NPT thread converter now in 3/4" NPT * male/male/male Tee connector * female/female coupler chaining thusly to create a manifold * F cap

7/ then off of each of the third legs from the T connectors, we go to a 3/4 NPT F / F brass ball valve. These give us on/off capability for each zone. Coming out of each we have an NPT / PEX "sharkbite" connector. Then we run PEX through the barn, using J nailing hooks ...

8/ ...and 90 degree bend supports. We do one straight run of PEX to each destination, where we then convert back from PEX (via sharkbite connector) to 3/4" NPT, which connects to the sow water bowls. Eventually there will be ~ 20 or so zones. For now, though, just 4.

9/ Phase 2 is to add the remaining zones. Phase 3 is to add bypasses around each manual control valve, which are controlled by DC servos, so that I can have software do it all for us.

The only piece of advise I can give is, don't use the plastic fittings. Go brass. The plastic seem to be bad. And if you are running a ton of the stuff, get a really nice pex tool.

yeah, I wasn't thinking about plastic; def brass
