Questions on crossroads cruiser

[stew47]

Well its first day in our new to us 2010 32bl. First thing I started filling water tank with a little bleach and running faucets to de. Winterize. Some questions are...
There's two small blue knobs below the city water intake and black water cleaning intake.... What are they for?

Water started running underneath the trailer from a pipe protruding.... Is that a fresh water overflow?

The separate black water and grey water discharges puzzle me after coming from a Winnie with single outlet. What's everyone do just move slinky over when it's time to dump the black otherwise leave on gray?

The two valves for water heater bypass..... Never used before... How you use?

Lol I'm sure I'll have more thoughts later.

Be careful about sanitizing the fresh water tank. On our 2014 32 ft Cruiser, the fresh water tank drain was plumed about 1 1/2 inches above the bottom of the tank and to drain it completely I had to find a hill and park on it sideways.

Found the cap! I have a feeling I should buy a couple extra

Thanks all. Got the hot water on and all is well. Pulled a panel off and the bypass valves were easy to see, figured out the pipe is an overflow for the tank, the blue knobs make sense now. Is there a separate tank drain? After looking would the front drain be black and grey and rear pipe kitchen drain?

Very possible since black and grey both come from the bathroom and if the kitchen drain is some distance away it will have its own tank. But depends on floor plan. The fresh water tank drain is separate and should be just a white plastic cap near the rear jack

When I had two separate sewer drains, the second one was gray water only and I used a cap with a hose fitting, a 3/4 inch garden hose and the fitting at the sewer pipe had an extra hose fitting as well. So I could drain everything as needed w/o moving the sewer hose or carrying a second hose.

I have a crossroads bunkhouse.
On ours we have a black and grey tank up front that drain through one pipe.
Pull the black let it go and then pull the grey all drains.

I also have another tank in the rear of our RV for the second bathroom. The dump handle is located near the frame in the rear. I do have a second hose for that tank so I don't have to keep changing them back and forth.

The blue knobs are the low point drains for cold and hot water lines. They have to be closed for water pressure to build in the lines. Also, if the water heater had no water in it and you turned on the electric heater, then you probably burned up the heating element. It is important to always confirm that the tank is full of water first. If the tank was properly winterized, then the bypass valves need to be turned 90 degrees in order to fill the tank.

Rats ..... No hot water either. I was using electric. I have to get propane tomorrow.
