Size of outlet on my hot water valve for dishwasher supply
I was going to guess the valve outlet is 1/2&quot; compression (if threads are very close together). If not, the it's 1/2&quot; pipe thread. There are no supply lines for 1/2&quot; compression at hardware stores these days. If it is pipe thread, then you're in luck and a different hose can be substituted. Otherwise you'll have to replace the valve. I recommend getting a 1/4 turn valve. They last longer and are more durable, easier and quicker to turn off.
To make your life easiest, I strongly recommend replacing the valve. You will need a 1/4-turn, 1/2-inch pipe inlet and get a 3/8 compression outlet. Most faucets and dishwasher hoses will use 3/8&quot;.
Btw, the above brass adapter will not work on your valves if the outlet on the valve is 1/2&quot; compression. You'll have to find a 1/2&quot; female compression yo s 3/8 female compression, which is basically a hose, not an Adapter. You won't find this as an adapter at the hardware store.
