What size line do I run from pump house to shop and from shop to garden faucet?

Hi integrity:

Hmmm... need more info. Here.. ok? Let us know what fixtures will be in the shop. Are you installing drains and vents or just water?

Let us know

Will have utility sink with cold water only and greywater drain line or some kind of outdoor pit. Will also run pipe for faucet to outside wall of shop and line to remote faucet in garden area.

I would run a 3/4" copper pipe and then send a 1/2" pipe to each fixture.

Branch off the 3/4 with 1/2" to utility sink, then 3/4" over to the outside wall faucet where you branch off with 1/2", and then reduce to 1/2" to run 1/2" to the remote garden faucet.

That should do it for you... ;)

Thanks Mark, very helpful.
