Fresh Water Drain

[St1tcher]

So I'm attempting to drain my tanks and I noticed that on my 2012 Coachmen Catalina Deluxe 28DDS I don't have a valve to start the drain on the outside. In this picture you will see far away is my low point drain and closer is my fresh water I take it. The reason I say this is because while filling up with fresh water the dealer stated that the water will come up through the vent. Well as of yet that hasn't happened. Everytime the tank says it is full, water has been coming out of the white hose next to the drain for the fresh water side. If I'm not looking in the right area could someone point me in the right direction? Thanks.

I'm not sure I follow. You mentioned a "white hose next to the drain for the fresh water side", but that white hose isn't shown in the picture. I'm gonna have to guess here: the blue one in the distance is your cold water low point. The one in the foreground is your hot water low point (not to be confused with the water heater drain) because it is really a red line with a different fitting put on the end of it. The white one that is not photographed is the fresh water tank drain.
I am confounded by the "T" in the drain that I have deemed the hot water line.
Note: a tube without a cap or fitting is an overflow vent.

In the picture with the hoses closest to the camera near the plug you will see the white hose I'm talking about. Sorry it was dark out when taking these pictures. With the hoses off in the distance there is a blue hose and a red hose. The red hose you really can't see but it is directly behind the blue hose and these are the low point drains because that is on the side of the TT and you will see both of these hoses and it seems all of these have the same plugs on them. My hot water heater drain is at the back. There isn't any hoses coming out of the back for that.
