Water escaping
at pressure relief
valve.
Water pressure in water system too
high.
Adjust the water pump pressure to a
maximum of 65 psi (4.5 bar).
If the water system is connected to a cen-
tral water supply higher than 65 psi (4.5bar)
(rural or urban connection), a pressure
reducer must be used.
Install a pressure reducer (e.g. Truma
pressure reducer) at the fresh water
supply.
Water cannot expand in the water
system.
Contact the vehicle manufacturer about
retrofitting a pressure compensation ele-
ment.

relief valve seat.
Allow the appliance to cool and then
slowly raise the test lever (Fig. 3 – 4a)
to flush the water system and attempt
to force dirt or foreign matter out of the
pressure relief valve seat.
Replace pressure relief valve. This must
be performed only by a certified service
technician.
