Hi all, I have once again fallen for the B&Q scam!?

two years ago I bought a Mac Allister power washer mk4 the best I could afford! got it out of the garage today, fitted the hose and is spewing water out from the connecting plastic fitting from hose to pump housing... fitting has split! rang the Tel. No on machine to speak to a total idiot who told me to get one machined as they dont know who manufactured it??? In this day of internet global knowledge sharing, surely I should be able to locate a £1 fitting? seems not? If anyone can help please let me know............ Mr angry of York.
