Outdoor Cleaning with Pressure Washers

Replacing O-rings & Screens

Step 1

To replace an O-ring, use a small flathead screw-driver to pry off the worn or damaged O-ring and discard. Install an O-ring in the same position as the old one.

Step 2

Cleaning & Replacing Water Inlet Screen. Use a small flathead screwdriver to remove the inlet screen from the hose connector. If the screen is clogged, flush it and the hose connector with clean water. If the screen is damaged, replace it with a new one with the dome-side of the screen pointed outward.

Step 4

Cleaning & Replacing In-Line Screen. If the screen is damaged, replace it with a new one: Place a new screen into the threaded end of the wand, pushing it in with the eraser end of a pencil until it rests flat at the bottom of the opening. Be careful to not bend the screen. Place a new O-ring into the recess, pushing it snugly against the screen. Reattach the wand to the spray gun.
