Hi all,
The area under our (water closet) vanity sink has a habit of getting wet. It has been doing this randomly (at least it seams random) for a couple of years now. At the beginning of this when the amount of water was not as bad, I was assuming things like the sink drain joints which so commonly get loose in RV's. I have replaced the drain, the joint seals, and the faucet, yet no change. Now when we find that it has flooded, the water is all over the place. I cannot tell where it is coming from. There are two things I'm wondering about under there. One is the drain's under sink vent. I checked it, and it seems fine. The other item is a bit of a mystery (see attached picture). I'm assuming it is a check valve with arrows pointing from blue to red, which I assume is cold to hot. Does anyone know what this is for? Can I just cap them off?
Thanks,
Jon Wells
