Re: Fresh water precharge accumulator

Tommy,
Please modify your signature to reflect what coach you have.
But, assume you have an accumulator on your system.
If so, and it has a shredder valve (common tire valve) here is what you need to do:
Shore water and water pump OFF.
Open a faucet to depressurize the water system.
Use a small screwdriver or equivalent to very quickly push the shredder valve. If water comes out, STOP-- the diaphragm has failed and you need to replace the accumulator.
If no water, check PSI with regular tire pressure gauge. Set it to CUT-IN PSI minus 2 PSI. For many older pumps, that is 25-2=23 PSI.
A bicycle pump or any air source is fine for setting proper PSI.
