I have two bathrooms in my home, built around 1991. They are on opposing walls, as in mirrors of each other, for the sake of structural symmetry I suppose. One shower has wonderful pressure, the other is lousy by comparison. They both have Mixet valves. I have replaced the valve cartridge in the one with the low pressure twice in the last 10-15 years, mostly due to an undying hope that the pressure would improve. I have not replaced the one that has the high pressure yet because "if it ain't broke". What am I doing wrong? Is my house on an ancient Indian burial ground, should I call a priest, or maybe Ghostbusters? I do not have the mixing problem I have read so much about, temps seem to work properly in both units. The only difference I can tell between the two units is that the one that is still original (high pressure) has a slightly shorter retaining nut for some reason. To me this says "variable". But I would think that this would indicate a shorter cartridge if anything. But shorter, to me, seems like there would be less opening movement resulting in lower pressure instead of higher. But I'm not exactly sure how the whole thing works inside anyway, so I speculate. Unfortunately since I have not had this one apart, other than to update the handles, I don't know what differences may lay just beyond the nut if any. The only other thing that I can think of is that maybe there is some type of adjustment in/on the valve assembly itself which is hidden behind the shower enclosure. Sounds crazy, but I've seen crazier. Can anyone help me out with this mystery?
