Old style Truma Dump valve


Bennett Family
 

When you turn on a tap in my son’s 1996 Hymer B544, a very small trickle comes from the tap an water seems to be running out via the dump valve (I think). It had an on/off switch and a yellow press button. Any idea what position they should be in. The English Instruction brochure shows the more modern pull up unit, whereas the German one shows the correct one but I don’t read German.

If the unit fails does it default to emptying?

Any clues would be appreciated.
Photos attached.
