![]() With Kohler weird parts, I have occasionally had to leave a client without house water, while I run around getting tech advice from Kohler or more parts from local supply house.Īll because some jerk cheaped out and did not spec the valve with stops. I just don’t want to yank out the existing pressure balance unit, then find that what parts I have won’t fix everything back up, at least leak free with the tub unused if necessary.īack of one package looks like right valve, with three tabs on each side, back of other package looks different. The new one is more like a narrow oval shape, lots of unfilled space above and below.Īnd does the old disc shape part just wiggle out, is there a keyway, can I just yank with pliers? That is pbly fine, as long as the new pressure balance unit is a major re-design, totally new shape, but will fit and mate up with new cap design.Īlso, old pressure balance unit is a full disc shape, it fills up the whole recess of the valve. It looks like they eliminated the loose springs and Delta-style rubber boots.īut the new cap will not at all mate with the old existing pressure balance unit. My main concern is that the new mixing cap is totally incompatible with the old existing pressure balance unit. This old mixing cap is held on by only two heavy phillips screws. I recognize the old valve body, but can’t pull the trigger on re-designed parts install until I am certain all is in place to button it up. I did not remove the pressure balance guts today, once the parts on hand seemed mis-matched.īecause everything is old and dry, and would likely leak, after re-assembly. I have worked on some similar newer ornery Kohler valves that feed the sides of the valve body at 9 and 3, and the pressure balance unit has to be twisted in while trying not to carve up the seals. I think this valve body feeds from the back, sorry the pics don’t show supplies very well, and I was only over there a short while today. I have opened the wall and will be replacing the old galvanized water supply lines and faucets. You can see on the back of the packages, one valve body pictured looks like the one here, with tabs on the sides, the other is round like a port hole. I also show pics of the two parts he left, the cap “might” be right, but I think only if the pressure balance unit current upgrade part is now way different. There were little springs and rubber boots between the mixing cap and pressure balance unit, similar to Delta junk, but longer springs. There is a pic of the trim and handle, etc, if that narrows down the year or version of this valve. Pics are included of the valve body with the original pressure balance guts still installed.Īlso a pic with the original mixing cap still installed. I hate most Kohler stuff, too much crazy variety and poor designs. I know Kohler changes parts, makes old parts obsolete, re-designs, etc. They had hired a pro, who ordered parts twice, both times wrong, and then he gave up and quit. I need to know current part numbers of the correct mixing cap and pressure balance unit.Īnd any tips if anything to watch out for during replacement. So I was asked today to wade into fixing this dripping older Kohler tub/shower valve, by a neighbor of a looong time customer.
