To empty onboard water tank in a Bailey Cordoba?

 

I should have said does the yellow switch by the heater (not the pump) drain that also?

Sorry for any confusion!

My Bailey is a good bit older but the drain for the inboard tank is outside, underneath, and quite a way back from the tank.  Have a look for a pipe from under the tank leading to a valve hidden somewhere.

You can use the yellow valve and a running pump to empty some of the water, but not all. There will be some in the bottom of the tank well, and in the drain pipe.   There will also be water in the other pipes in the caravan, as yellow valve does not deal with any water that is "over the hill" from it as pipes wind about inside.   I have drained my caravan using air pressure and get about another two litres out that way.

When sterilising, remember to deal with that length of drain pipe as well.

It only has a hot water tank the cold just gets pumped from the aqua roll straight into the van from the outside 

It doesn’t have a onboard cold water tank just a hot water one 

That’s strange as there are several hits on Google for filling the onboard water tank, including this old CT thread -

It's no help to the OP I’m afraid but looking at the Bailey spec it looks as if maybe only some models have the onboard tank.

The Cordoba does have a 40 litre water tank.  It's a black plastic one at left side of the offside bed box.  Can post a photo if anyone needs it.

Filled via normal supply, but valve has to be switched on, until it overflows to outlet outside (meaning the tank is full) and then switched off. So water will be to top of tank.

Another David - Don't think there is access above the tank to get to any screw on cap as that is the front of van, with no access as far as I know. Don't know where exactly the internal pump is located.

Navigateur - I have found a pic of where the outside drain is and will see, when we get some dry weather, if there is a valve there.  Person we bought off said they had put a hose on the end of taps and blown back through them to drain the water.

Think I will have to clarify with previous owner re the onboard tank.  Don't know if they ever used it anyway, but it is recommended for winter use rather than the aqua roll.

Can't understand why there is no diagram of how it all works and which valve is where - jobs for the boys comes to mind! :0)

Thanks for all the replies

Ha!  The pump and valve diagram.  The one in my van is on the inside of one of the locker doors, but not where the pump and valves are located.

Just found this video regarding a Bailey Unicorn 4 - but the valves appear the same as on my Unicorn 3 - at least the two I found.

The one on the blue pipe I thought was for filling the onboard tank is actually the drain down valve - and that is open (with easy access from the front of the bed box).  The other I found is indeed the yellow one for the Alde heater which needs access via the top of the bed box.

It seems the bed box also needs to be open from the top to find the valve to switch from using the water hog pump to feed the taps, to it filling the onboard tank. Once the tank is full (check for water overflowing under the van) turn off the valve used for filling the onboard tank, and switch to internal pump in van to take water from the internal tank to the taps..

I hope the youtube video is useful for others.

I have a 2015 Cordoba. The above is correct. If you are using water from the onboard tank, you need to switch the pump from external to internal at the control panel. Its all fully explained in the handbook.

Its a real pain having to open the bunk from the top to switch between aquaroll direct use, and filling the onboard tank.
