  • Sounds like you have the same problem as me. Yes, a new seal on the high pressure output should do the trick. Not necessary to strip down m/c. I have to replace mine each spring and I have come to the conclusion that frost may have got into the works. The 'shunting' you refer to is the m/c trying to maintain pressure in the high pressure hose. Hope this helps. Pack of 5 'O' rings should last you a few years, but keep the m/c away from frost.
