My Prevost friend just replaced his Mach 5. Headhunter did an exchange for $ 500. His old one was 5 years old. The board went out, a new one was $250 or exchange for $500. Looked it today I think he still has problems as it shuts off at 65psi then drops to 42psi. Cycles thru about 5 times then settles at 44 psi. His flow starts good then drops off. We're going to replace the main filters and see what happens. His system has no 12 vdc pump nor a accumulator.
