I've had my powerflite machine for about 6 months it's done about 250 hrs,the pump as been making a scraping scratchy noise near enough from new it happens when the pump is turned right up or on a lower pressure the noise comes and goes.Been on to the suppliers and he says that piston pumps are noisy ,I don't want to wait till the warranty runs out to find out the pump needs repairing.Anyone experienced anything similar.
