Plumbing ?? Help.......

[foamer01]

Greetings,
I really enjoy the knowledge gained here on this forum. It continually amazes me different ways to approach a situation or problem, ways I never have thought about. Here is what I want to do, I just want a solution that works and isn't OVER engineered. I want to connect 3/4 pex to 3/4 copper to feed my garage. That part is easy enough however I want to be able to disconnect the pex from the copper and have a fitting that would attach to the pex and blow my line out before the frigid air sets in for the winter (next season of course). What would be the best way to approach this?
Thanks,
Foamer

Why not just bury the pex below the frost line and be able to use it year round. Not sure on where you live but the frost line ranges from 12" in the south to 42" in the north.

If you are serious about wanting to disconnect it in the winter I would look at something along the lines of an air or hydraulic quick connect coupler

You could plumb in a 3 way valve. Not this one specifically, but something similar.

Plumb in a valve a T and a valve in to the T, feed thru, use the valve to get back in to the secondary. I should have some pu ics, this is very common. You can also get a valve with built in drain, can use a tire fitting to blow down past it when off.

Yes, the 3 way is cool, Is it stocked off the shelf somewhere? Usually I use a T and an old boiler drain, can use the same air fitting as the hose bibs. You can probably see an adapter to hose in there, you don't need a valve but I have several and can make any combination in a minute, some pretty much stay as is.

I have 4 or 5 outdoor circuits and make my own frost proof for the shop with a series of valves due to the fact that common ones are too restrictive, we are filling tanks and running sprinks larger than water savers found in residential.

I didn't think of that but you're right. I have those shutoff valves on my outside taps, and in the fall just open the little bleeder screw and the water drains out by gravity, but you could use a tire fitting to blow the water out.

This winter the frost is down to 6 feet or more around here.

To blow out our sprinkler system I shut off the feed, open up the hose bib that is t'd in outside on the feed line and connect a hose I have made up that has the connections to my air compressor.

Simple and quick.

I just ran across this fitting, http://kscdirect.com/item/NIB+PX20310/NIBCO+INC_PG36+1%2F2+PUSH+N%27GO+Garden+Hose+Adapter

I think it may work I wished it came in 3/4". Any ideas? Are there any other pex fitting that swivel/turn so you could get them on or off a NPT? Then again maybe I am over thinking the situation. My pex was pulled through a 1 1/2" conduit buried over 48" deep and brought up through the floor into the garage. I'm in Michigan so it does get plenty cold. I have heat but not for certain that it will be on all the time. I just want to avoid problems.
