The Manufactured Housing Forums

I'm having a friend install an outdoor water spigot (for use with a garden hose, pressure washer, etc.) for us that will be created by tapping into our water line. What parts would you suggest I'll need to buy? (not sure where everyone is from but I live in upstate NY with stores like Home Depot, Lowe's, Agway, Allerdice, etc.). Trying to budget out the parts before I go buy them. Thanks in advance!
