Can I use 1/2" FIP to compression fittings to attach 1/2" copper tubing to my Delta universal valve housings for my new showers?
Our Tucson hard water will eventually eat away at the faucet valve housings, and I want to be able to replace the valve housings in the future without major surgery.
I thought about using brass 1/2" unions, but they go for about $7-$10 each, and the compression fittings are about $3 each. It would take 4 unions for each faucet: 1 for drop ear shower outlet, 1 for cold inlet, 1 for hot inlet, 1 to tub spout (or cap the bottom outlet for a shower only).
I thought about using PEX adapters, put I don't know how you would get a PEX crimp tool in the small opening for the valve, not to mention the extra PEX slack you would have to allow for future replacement.
Tucson uses UPC - so I don't know if UPC allows compression fittings, or unions, inside walls.
Thanks
