I'm guessing this system has an original pressure of 2500-3000 PSI, dropping to 250 PSI might be a problem. Hope it is not for you. Should you need additional technical information about the full-size PC1800, let me know. Be glad to assist.

You might be right about the relief valve not liking the the low pressure, I wasn't thinking of that style of relief valve in there not a simple ball and spring, if it wants to float around at the low pressure I will need to add an external one on later to correct it....l will try it first and and see what it will do...maybe just maybe it will work with the low pressure.
Do you work on this machines or operate them??
