OK here we go... I have a CPR CS90B (the "B" is for black) anyway.. Help me quite the crazy gurgling... CPR thought they had a way out with this tube like insert that gets placed down the middle of the drain pipe to let air escape from it.. But guess what... It doesn't work so great.. I went with this piece of eqipment because I didn't want a pain in the ass "J" pipe out the top of my tank.. Besides building a cover for it out of Poly Carbonate, can anyone help me quiet this crazy toilet flush...
