Plumbing question during kitchen faucet replacement
We are replacing the kitchen faucet in our ‘96 Rear Bath.  All was going well, with the old faucet removed and new one in. We purchased the BrassCraft 1/2” non comp inlet to 3/8” od comp with 1/4 turn valve to connect the new faucet lines to the existing hot and cold water lines. The parts seemed to fit fine, until we turned on the water pump and watched the water show! It leaks from both above and below the connection (see photo). The light grey plastic female piece where it leaks is the water line.

Yes, we tightened by hand first, then did another tightening with tools. No, we did not use any kind of tape or sealant inside. We’re not plumbing savvy, but are fairly handy so any advice is appreciated!

The sink's Factory PEX supply lines have 1/2" pipe fittings. I can't tell from the photo what type of pipe fitting the faucet uses.
You needed a valve with a 1/2" pipe fitting on one end. You will need to determine what fitting the faucet's flexible hoses use, it doesn't appear to be 1/2" pipe.

Thanks for the quick reply Larry. The pipe fitting is 1/2 inch and the new faucet is 3/8 inch which is why we bought a connector piece.

Your valves are 1/2" compression. you need 1/2" male pipe thread.

One thing that might help is to take some photos with your phone of the piping you're trying to connect, then take it to the hardware store and show their plumbing expert who should be able to hook you up with the right parts and advice.  Good luck!

An alternative is to use push-to-conntect (Sharkbite and others) fittings. I've used them in different rigs over the years. Easy peasy and no leaks. You just cut the pex and slide it on. Here's a link to a 1/2-1/2 for example: push-to-connect

Thank you all, the connector/adapters are in and the faucet works well!  Larry and Jor, we started with reading your past posts on  faucet replacement and viewing your pictures.  All were very helpful, and all help and encouragement are appreciated! We felt equipped and bought the shark bite option and the Brass Craft ones in our picture.  We compared the threads on the old faucet pipes and they didn't match the connector that we had purchased, so the crew went back to Home Depot and bought Everbuilt 3/8 to 1/2 in MIP compression and they worked.  Around $16.00 for a package of 2.  I wanted a shut off valve but I wasn't there, so no vote.  Just glad it works and now to secure all those over-long hoses.  (The down side of using a regular sink faucet.)  If anyone is considering a replacement, we got a MOEN Brecklyn pull out option with one handle, $109.00.  The optional plate at the bottom was the same footprint we had. Here is the connector for the new faucet to LD water inlets.

So I wonder as an "Old Ldy" RVer, how I mnaged years ago to do this facet replacement by myself?
 It still works perfectly another  decade later.  It's not easy with big hnds, I think. Stubbonness helps.

Hi Kristin!  When we crossed paths in Albuquerque at the balloon fiesta, you struck me as a very capable lady.  Deb and I had a nice time when you invited us over and showed us your rig.  I was just thinking of you the other day and how you had the neatest pot from Mexico that you cooked with.  I'm sure your stubbornness has paid off and hopefully that will help me too, since my next job is replacing the ball flush in the '96 RB.  Warm regards,  Mari
