It looks like another drain knob. Pop your head under the MH and see how many drain pipes are sticking out through the floor.

We have the same on our caravan

Try turning it

What type of heating and boiler do you have? Some systems may have a separate frost protection valve on the boiler and a drain on the fresh water tank. It is important to make sure you follow the right procedure to drain down for the winter.

My boiler is a Truma B10

Did you try turning the knob or are you not near the MH?

Motorhome is in storage will try tomorrow.
Other information the fresh water holding tank just has a plug like in a sink so I know that is empty now.

I have not had a B10 but there will be others who have. The yellow and blue knobs may be all you need, not sure.

It is the drain valve for your hot water line, (red pipe).
Only open it a few quarter turns, otherwise it will come out completely, with it's sealing O ring attached.

With both valves open, (and any others you come across), once drained, remove the shower head, open the tap, and blow through the hose to force out any water left in the system, ready for winter.

Cheers,

Jock.

Yes Richard, I had two of them on the Hymer, and one was leaking, hence the removal once drained down. It turned out to be the casing for the valve which had cracked, so a replacement was sourced.

Cheers,

Jock.
