I'm connecting a dishwasher for the first time. Under the sink I have what I believe is a 1/2" OD male threaded supply line. I guessed this based on the fact that the flexible hose has a label that reads "1/2 OD in to 1/2 FIP out". Please see attached picture.
I thought I would be able to buy a 1/2" inlet to two 3/8" outlets, but my local stores did not carry anything like that. I bought this dual outlet valve, but the fitting was too large for my supply line.
I spoke with two different people at HD, and both of them seemed really confused that my supply line was 1/2" OD. They kept trying to get me to buy the 1/2 FIP again even though I had already tried it.
I tried to buy a 1/2" OD to 1/2" FIP adapter, but couldn't find any at HD.
