the new hoses have been pressure testing for 24 hours now. we did find one small leak on the front new hose that just needed cinching up at bit more but we found that last nite.

does anyone know what acceptable pressure drops are in pressure testing a cooling system like our coaches have?

i pressurized it up to 16psi last nite. this morning it was at 14 psi and it has held steady all day at that.

so down 2psi in 24 hours.

i have no idea what is acceptable. i also think the pressure tester i am using might leak ever so slightly

any wisdom here?
