I'm trying to get water to my sink in an unconventional setup. I have a water tank and a water pump so I don't need a shutoff valve under the sink. I have 1/2" female PVC stubbed up, and I have the two female 3/8" compression connectors hanging down from the faucet with a merge connector bringing them into one (I won't have hot water). I'm just wondering what's the cheapest and easiest way to connect these two? I can't seem to find any connectors that would work. It would be easy but I can't figure out how to connect to the compression threading with anything that can go into 1/2" female PVC slip joint. I would really appreciate some help.
