Pressure hoses use engines to compress water transmitted through the hose. They create a pressurised stream of water, good for cleaning excessive dirt and grime build-up on surfaces. As the name implies, pressure hoses contain a lot of internal pressure, causing it to be susceptible to leaks and tears. If you spring a leak in a pressure hose, traditional repair methods like tape or epoxy do not suffice. A pressure washer hose is best repaired by cutting out the leak and replacing it with a new coupling.
Unplug the hose from electrical sockets and cut off power supply if it is running.
Press the hose trigger to discharge excess water, if there is any.
Locate the leak or puncture in the hose and dry off the area around it.
Grab your scissors and cut the hose on each side of the leak. Be sure the cut is clean and straight across.
Insert male repair coupling at one end of the hose and female coupling to the other side of the hose. Crimp the ends and fasten any compression rings if necessary.
Connect both couplings together and tighten securely with your pliers.
