Is a habitation check worth it for a decent mechanic to have done on their van.

I've normally checked gas system soundness using a water manometer - one does have to wait a while though. The soundness test you do pressurises to around 20psi. How long to you wait for a drop in pressure? I'd assume that using the higher pressure means very little wait.

I'm afraid you're out by a factor of ten, 5 times normal working pressure is 2.25 psi aprox. 1Bar = 15psi/1000 (1mbar=1000th of a Bar)=.015psi per mbar. Normal working pressure for MOST modern motorhome/caravan systems is 30mbar so 30X0-0.015=0.45psi normal working pressure X 5 for test pressure =2.25 psi.

Once pressurised the system should be left for 5 minutes to normalise then topped up if required, test time is 5 minutes.

Habitation service not a condition of warranty on Hymers, a damp check is, but that is a different matter.

It is on Rapidos
