I just bought a new fluidyne. The install was very easy and striaght forward, however, the bottom drain plug leaks. It seems as if coolant is coming out of both the 'bigger' nut and the smaller hand twist screw. I've tourqued both screws to hell already and i has just slowed down the leak... its really pissing me of now. Has anyone had a similar problem w/ their fluidyne? Anyone have any ideas how to fix this?
