i had this happen about 3 times now....the black mess i find is really easy to clean up. one burst right at the end of a job, took an extra 20 mins to clean carpet and wipe down....i have a local guy to me who fixes mine for a tenner, cut pipe, re crimps with new end bit and retreads the QC, also sells a lot of bits like QC and also the actual solution line i think a 50 foot piece is about £75.00, tested up to 3000 psi
