tying into pexhose

I'm using 3/4x3/4x3/4 T SharkBite to tie my water line, which is made of 3/4 pex, to my PVB device. Will the SharkBite fitting hold at 65 psi? If not any other suggestions?

A Sharkbite is supposed to hold 65psi. Would I want it at my home, nope! Tie into your PEX line with proper pex fittings and PEX crimp rings.

There are plastic compression fittings made for working with PEX, although they may not have the "install it behind a wall" trustworthiness of the conventional PEX crimp fittings. Also, since PEX is copper-tubing-sized material, one could use waterworks-quality compression fittings to connect to it. Either of those choices is far less expensive than the cost of owning your own crimpimg tools for conventional PEX fittings.

I used a Sharkbite fitting to repair a garden hose spigot. I wasn't terribly impressed with it. I will probably change it out in favor if a PEX fitting and copper compression rings.

You shouldn't have to purchase a PEX crimper if you're only doing a fix here and there. A lot of hardware stores will rent the crimpers to you for a couple of dollars, and some will even lend them to you to use for a couple of hours if you purchase the fittings from them.

Just following up, I tapped into my house main (1" PEX) using this nice little compact crimper from FleaBay.

Worked awesome and the auction includes your choice of ten copper crimp rings.

I don't like the plastic compression fittings -- for best results check with a plumbing supply house and get a brass compression fitting. You'll also need a plastic furl for any connection that will be on plastic pipe.

re: Shark Bite fittings. One of the plumbing supply houses in my area has been carrying Shark Bite fittings since they came on the market. A couple of days ago, I asked one the salespeople if they ever had any complaints since they've been selling them. He said they've only had one complaint -- the person put the connection together WITH GLUE and complained when it leaked.
