Hey guys,
So my unit is a 2008 Cyclone 4012 that we purchased used, from a small lot, with no intro to the systems or anything. It has a UDC that looks EXACTLY like this -
The biggest thing to note is that mine has NO stickers on it to say what does what. None, not a single sticker is left alive, not even at the city water connection (but it doesn't take a rocket scientist to know what that does). So I have learned through trial and error that of the two valves shown here on the blue tubes, the valve on the right is the low point drain for the water system. I also learned that I can run the pump and drain the fresh water tank through this valve. So I think I understand the valve on the right (even though this one clearly states it is the low point drain, mine had no sticker, so I learned on my own).
The big question here is this -
What is the valve on the left? What does it do? This valve on my unit has been "open" (?) since I purchased it (I'm assuming it is open because the little handle is pointed "down" just like you see in this picture, which opens the other one when pointed in the same direction). I read in an archived forum posts that the valve on the left is the hot water low point drain. But if that's the case, why was I able to turn on the hot water tank and get hot water at the shower with this valve in the open position? I don't think it is the hot water low point drain. Or if it is, mine is not working correctly because it seems to be closed when in the open position.
Is there a diagram or manual for this system that explains how everything works? I see tons of manuals and diagrams for the Anderson 4-way setup, but what about those of us who don't have that system?
I also see 3 tubes coming out of the bottom of the RV. I know the one is the low point drain for the valve on the right, because when I opened that valve water began coming out of that tube. No water has ever come out of any of these tubes with the valve on the left in the open position, so the remaining 2 tubes are a mystery to me.
Also, bonus points for anyone who can explain how to get that stupid blue water hose off of the water outlet shown at the top of the image too! Mine appears to have a connection similar to an air hose (quick connect style) but it doesn't seem to budge no matter what I do to it. All it does is spin around and around! Not that I don't like the hose there, but it's a pain in the butt to constantly have to work around the hose and spray nozzle that is hanging in the bottom of the UDC area.
