Welp, I need to get different fittings for the water lines into the brick. I received metal 90 degree fittings as opposed to the plastic ones I typically see with this kit, and they only want to thread in 1/4 of the way, stick down way too far, and will become too loose if I try to index them the way I need them. Anyone know where I can get plastic chemical/heat resistant plastic 90 degree 3/4 barb to npt fittings? They really need to put AN fittings on the brick.
