Simply used an adjustable wrench to remove the thermal relief valve. The new one came with lock tight on it already. Screwed in the new one and popped on the plastic 90 degree fitting so the water if it did come out again would shoot straight down. Best thing to do if you have to goof around while power washing is to keep triggering the gun or shut it off so the water in pump doesn't heat up and pop the relief valve.
