Going to put a hydrant inside the shop so I can have a sink. Got some pex with the copper rings, brass fittings and crimp tool. I have pvc a few feet away to hook to. This is the first pex I have used. Kind of a test run. It doesn't like much crimp seal area on the fitting to be burying 3 feet down. Going to put a pvc t in and adapt to pipe thread. What do you pex guys say?

Maybe I am reading your post all wrong. From what I understand...Why would you put a PVC 'T' and adapt to pipe thread? Instead, just install a brass PEX 'T' and a 3/4" pipe thread /PEX fitting to connect to the hydrant. Like this one...

That way you can avoid PVC altogether.

Since you bought the PEX crimper tool and the clamps, you might as well utilize all the components available to you.
 
PEX works very well. Don't be afraid of it at all. I've been using it for the last 10 years and have never had a single fitting leak. I refuse to use those Sharkbite things - I use the real fittings like the one pictured with the compression bands.
 
I don't follow you. I have 3/4 pvc running by the building that I need to hook into. I thought a 3/4 pvc t and put a pipe thread fitting in the output.
 

mf294-4- Although, this may not be exactly what you are looking for, you can find what you need.<p>With this 'Tee" you can hook into your existing 3/4" PVC line and run another line to your hydrant using PEX.

Original landscapers in this area installed 1" PVC in backyards, but didn't use any expandable connectors so when the ground warms up in the spring it breaks a regular PVC fitting and floods the neighborhood. If you are using PVC underground, it's best to install a PVC "slip" connector to allow for expansion and contraction of the soil.
 
You won't have any problems with PVC pipe if you bury the pipe below the frost line.Around here we bury line 5-6 feet deep and have no problems.
 
I used pex on just one job and hate it. I used shark bite on my boy's water heater to
adapt flex pipe to 3/4 hard copper. The braided flex pipe even came with a shark bite
fitting on the end. I wouldn't use pex or shark bite under ground.

When I had a new well installed, I had a hydrant installed a few feet form well head.
The well guy used brass T and stainless clamps on the black plastic pipe. If you have
issues pushing fittings on the black plastic pipe, use a heat gun to soften it up a
little.

PEX and braided "flex" pipe are entirely different things[color=blue:890fec43df][/color:890fec43df]
 
You should have at least 4 feet of galvanized pipe before the elbow to your yard hydrant. This will prevent the plastic pipe from breaking if you have to remove the hydrant.
 
My wife's older sister had all her water lines replaced using pex. She lives in Florida and has no basement and her
water lines are in the attic. She had to get 3 estimates from plumbers and her home owner association paid for it.
She never mention's any leaks when she calls. She will be 88 later this year and was diagnosed with breast cancer.
She ran track in high school and won every race. She was good looking too and the boys would fight over her. The
oldest sister lives in Florida and she will be 98 and I think she will out live her son who's 70.

I had a leak in one of the copper pipes in 2006. It was hard to find the leak and to get to the pipe. I couldn't use a tube cutter and had to use a very small saw to cut the elbow off. I soldered a new elbow on the pipe and used pex and shark bites instead of copper pipe. I had to cut out a large section of drywall that was in a closet
to gain access to the leak. I used several drywall screws to secure the section of drywall and is easy to remove.

First I had to remove a lot of clothes from that closet. So far no leaks. Hal
 
All my underground lines are 1 1/4" black poly hose with Stainless steel barbed T's and fittings with all SS hose clamps.
Black poly can withstand repeated freezing and thawing where ever they are exposed to freezing.
I never had one burst yet in 23 years where they came out of the ground, and i have 3 water points that i use only in summer and i let them freeze up solid in winter. They are always under full pressure to boot.
