I have a Mi-T-M 4503 that is leaking from the coil outlet assembly. I was using it to pressure wash a large driveway and at the end it made a pop sound. Then started spitting water from the bottom of the unit. It looks like the relief valve shot of as I don’t see it on the side of the outlet assembly. This is just my guess from looking over the schematics for the unit. Anyone familiar with this?
Anyone familiar with these units?
Sorry, im not. Have you called a local small engine repair shop?
Yeah looks like the male end of your pressure relief valve sheared off when it stopped working. They need to be periodically taken apart and cleaned or replaced. You can use a straight flute screw extractor and beat down in as you turn. Heating the block would help just don’t snap your coil outlet beating a extractor in to it. You can also just pull the whole block off if you don’t trust it.
