Rated 5 out of 5 by Beastmode from Great shower valve for the price, Great shower valve period. Valve is solid. First time installing something like this. Must put teflon tape on the threads or it will leak. I had to take the fittings off the valve and tape it because I didn't and it was dripping.
The original post was asking if he had to sweat copper stubs to attach to the shower valve in order to make the connection to PEX possible. That would mean two sweated copper joints per each connection in addition to the pex connection (one for the copper male adapter and one for the copper to pex adapter).
Install the Sharkbite fittings onto the shower valve body. Most shower valves have a threaded fitting for the hot, cold, shower and tub spout. Thread the fittings onto the threaded outlets on the valve body. The fittings are threaded on one side and are push to fit on the opposite end.
