Kitchen sink

Winterized but guess I didn’t drain the sprayer head, it cracked.  Also no water coming, hot or cold coming out. Yes, the strainer was off so no clog there.  Managed to remove hose connections, no each chore there under sink, took that to Lowe’s with me.  Went to Lowe’s, had 1 replacement that might (have) worked.  2 Lowe’s helpers to try and match what PC had installed and what Lowe’s had.  Got 2 90* shark bite 3/8 to 1/2 to (try) to mate  to the PC 3wing nut on the PC side .  Had to go to the 90* so as to clear the PC wing nut.  Won’t tighten up enough the 3wing to the shark bite, it just spins.  The shark bite is intended for copper tubing.  Thought about just cutting off what PC has, spend a fortune on fittings and start over.  Ideas?  Trying to leave by Friday to spear fish.

Did you try to put water on, shark bites work on plastic as long as you got the right size,

Tarnold, I have no plumbing advice, but can feel for you. Went to retrieve our PC from the storage lot to begin our pre-road trip inspections, cleaning and packing, as we were leaving on Friday also for Spearfish. Found that our catalytic converter was stolen. GONE! Just got back from the mechanic after dealing with the police, insurance company, etc. He hopes to have it finished late Thursday giving us only a couple of hours to accomplish everything. Guess we'll make it work, will be leaving later than we wanted to, but at least hope not to cancel any of already hard to get reservations, especially on the weekends.
See you in Spearfish

OP
2 trips to Lowe’s, and 4 sales people.  Shark bite makes connectors for copper and pex.   They ARE different.  The first 2 people had lined up with the copper shark bite.  Not until I got home from the first trip did I notice it was for copper.  Second trip(this is 18 miles each way, I live out by choice) worked with a 3rd person who was filling in for the “plumber” sales person, but not any more help.  While waiting for the “plumber” to return for lunch(10:30 am but he comes to work at 5am) I found what I needed.  Ended up having to cut off what PC used and went with a 90* 1/2x3/8 shark bite for pex. This also has a shutoff valve as part of the unit.  Snaps right on with a good clean cut.  The install took about 15 min once I had all the right stuff.  HERE COMES A BIG HINT.  Part of tightening up the faucet to the back of the sink,  requires that a bar and nut be screwed on a stud that is part of the faucet, that is VERY hard to get to.  Under the sink there are 2 holes in a cover that is over your hot water heater.  This is for plumbing drain and water lines going up to the faucet.  STUFF A RAG IN EACH OF THOSE HOLES TO FILL UP THE CRACKS.  So that when you drop that little nut it does not fall thru the hole and down into the back of the hot water heater, never to be seen again.  I had a spare nut.  Anyway job done, now on to the next project.
