Water line Size

Hi all,
I have a 2009 Surveyor 235RKS. I noticed today that when I filled the fresh water tank, it immediately began to drain. I am hoping this is the drain and not an overflow. It looks the a cap is missing. What size line is it? Looks 3/4 inch.

Any help is very appreciated.

Is this the low point drain (should be a hot water drain next to it) or the fresh water tank drain (white plastic spigot)?

It's 1/2" NPT and the caps are hard to find.

The lines are 1/2" PEX. I replaced the caps on ours with pex valves. They're expensive, but now I don't have to remember where I put the caps.

Smib; When I picked up our new V-Cross, I had the same thing happen. I found they had stored the cap in the water heater compartment along with the anode rod, which was removed for the winterizing. I put a proper valve on the 3/4 drain to make it a little easier. If you do that, try to get a plastic valve. It won't shake around like the heavier metal ones.
