Customer Reviews

Fixed my hot water issue, easy to do, took less than 10 mins... Easiest plumbing repair I have ever done. I read the reviews and made sure I had some plumbers grease, you will need this to hold the O rings on the back when you insert the pressure balance unit. I wasn't having a leak problem, I was having a problem getting hot water from the valve. Plenty of cold showers. The old balance unit was 14 years old. It was easily removed after the trim was taken off and water was shut off with two screws. I used a pliers to remove the old balance unit.I put some plumbers grease on the O ring positions on back of the balance unit, put the O rings in place, and slid it back in place. I then put plumbers grease on the two O Rings on the back of the mixer cap, and some around the large outer O ring, these O rings were already installed. I placed the new mixer cap in place, and installed the two screws. Turned on the water, and I now have hot water again from the tub spout and shower head. I adjusted the temperature protection and re installed the trim with one additional screw. It took less than 10 mins. Preparing and reading all the documentation took longer.There is a great YouTube video that can be found here https://www.youtube.com/watch?v=YZ3RY5hFRrcIt shows how easily this can be done. If the link doesn't work, just search YouTube for 304:305:11748 Mixer Cap and Pressure Balancing Unit Replacement Parts and Temperature Adjustment. The video takes away any anxiety you may have doing this yourself. 5Plumbing parts should last at least a decade it's actually not too hard to install. The trick is to remember where everything was when taking the current mechanism apart. My pet peeve on parts like this has to do with the longevity of these items. My original part only lasted about 5 years which is a joke. I hope to get at least another 5 years out of this. By the way, the whole procedure lasted about 90 minutes for me. I don't know what other people are saying but just to get all the right tools from the hardware store, it took me a little bit of time . I also took pictures of the mechanism at every stage of disassembly lest I forget how to put things back together. Finally, you may need other special tools if you have a Purist lever mechanism to remove the outside cover. A 100 years of residential plumbing and we are still tinkering with plastic parts every 5 years. Something is not right. 3Fixed the leak These do exactly what they are supposed to do. Other reviewers referenced the You Tube video link below; it was very helpful. I spent far more time researching how to do this that the time spent doing it. One tip: if your prior unit has a small black square attachment that fits over the end of the cap that allows it to fit into a square female end of the handle, keep it to use on your new cap. Mine was so deteriorated that I couldn't pull it off the old unit. I had to go to five different stores (HD and plumbing supply stores) to find on for $1.99. Without it I couldn't have completed the job.304:305:11748 Mixer Cap and Pressure Balancing Unit Replacement Parts and Temperature Adjustment 5Easy to Install, even for novice Purchased these to repair dripping shower head. After reading several reviews, I decided the smart move was to replace both pieces at once, rather than one at a time. The hardest part was getting the handle off: mine has a bell shape behind handle, no exterior screws. Had to hold handle and use plumbing tool to pull bell shade in opposite direction--also had to remove grout as someone sealed with grout instead of silicone. Strange and a pain, but it came off. Very easy to install: I watched a youtube video to be sure as I'm not used to do the plumbing--hubby usually does but was out of country. Given I had to turn off water to whole house, I was definitely nervous. Went in very easily: note, if you don't have young ones and like your water hot, adjust temp before putting back together. Only issue I had was whoever did the initial plumbing installed something incorrectly, as I had to install the mixer upside down--installed correctly my cold and hot were reversed. I noticed the old one was installed this way, but installed new one according to picture and had to take apart and do again. (Of course, I had to remove again to increase hot temperature.) One more thing I now know how to do. 5SAVE YOURSELF GRIEF AND MONEY: READ THIS FIRST To DIY handy persons who will install this kit themselves: Two other customers noted the same problem: Kohler's new replacement for its mixer cap/valve is seated in the shower housing in the OPPOSITE position of its old mixer caps. Since Kohler doesn't tell you "This Side Up," you have to figure it out the hard way. In my case, I had to start over by turning off the water again at the mainline, removing the mixer cap/valve and reinstalling it by doing this: You would first locate the red collar on the valve stem of the mixer cap. The red collar is tucked next to a 1/4" high peg. The mixer cap must be inserted into the shower housing with the peg at 12:00. The peg in my old mixer cap is installed at 6:00. If you install the peg in the new mixer cap at 6:00 you will not get hot water. You must remove and reinsert the mixer cap so that the peg is pointing up at 12:00. Once installed properly, the mixer cap/valve works like it should. 5 stars for the plumbing part but 1 star for Kohler's failure to inform the customer of the installation update. You don't need a plumber to install this kit. I'm a woman and it was easy to do myself, except for the "backwards" installed valve. Kohler has an instructional video on its website that was simple to follow. ALSO IMPORTANT: You don't need to buy this kit, Kohler will ship it FREE via 2-day Fed Ex because it provides a lifetime guarantee against leaks. 5 stars for Kohler's lifetime guarantee. 5The valve works and it s a easy replacement. The installation of the mixer and valve was easy. The only problem was the original decorative trim pieces. I was wondering why there was caulking on a sleeve part and the bigger trim piece. There s a gap that shouldn t be there. So I put some caulking in the same location and let it cure for a few hours. After that I don t have to worry about water running behind the wall. I looked at the other bathroom that had the same setup and there wasn t any caulking. The trim piece and sleeve were fitted perfectly. I m not sure where the problem with the fit is coming from. Maybe the mounting piece is off? Other wise the replacement valve runs fine without any leak now. Installation of the valve took less than 10 minutes. Unscrew the screws and pull off the valve and pull out the balancing mixer. The 10 minutes included removing the trim pieces. 4Easy quick installation This was an easy installation. Just take out the old and put in the new. Some reviews I read seem to state that some people have a problem with installing the unit u side down. Yes Kohler should indicate which is the top for the mixer valve. You can determine which side is up by turning the valve before you put it on and looking inside from the back. The teardrop type holes allow more or less of hot and cold to come through. Assuming cold is on the right, the unit should have the bigger end of the left teardrop opening open to the max on the valve. As you gradually turn the valve clockwise, the left teardrop will decrease in diameter (less cold water) while the right side (hot) increases in diameter. This will mix in more hot water as you turn the valve clockwise.Hopefully I'll never need to replace the unit again. However, I found the unit on Amazon to be about $25 cheaper than it was in Home Depot or Lowe's. 5Threaded Collar for Bell Housing-Type Handle The instructions did not cover this plastic collar surrounding the mixer (not everyone has one) but a quick on-line chat with the Kohler rep solved the problem. It fits very firmly on the mixer, and if you have it, you need it for the new mixer. I removed the unit and did the removal on my work bench. Two flat-bladed screwdrivers slid underneath (not under the screw holes--they might break) the base of the collar (one screwdriver held by an assistant) and then twist both at same time insures collar will slide straight over the retainer edge of the mixer.Other than that, it is a simple project. Make sure you push the collar with the screw holes top and bottom as shown, or you will end up prying it off again, as it clicks solidly onto tabs on the mixer. It is a good idea to look over the new mixer and note these tabs. 5I am not Handy around the house and I was able to fix the shower After four years of use, Our Kohler shower became either very hot or very cold, no variability. On the internet this was a common problem. I used the Kohler website to find the correct part number. I bought from Amazon and saved $40 compared to Home Depot / Lowe's.I was able to successfully replace the old parts with the new parts and the shower works properly.Make sure to turn off your house water supply. I also turned off the water from the water heaters.FYI - our Kohler had a white plastic threaded sleeve that attaches the shower handle - this was somewhat difficult to remove - use a flat head screwdriver to pry the white sleeve off the old valve and re-install on the new valve AFTER the new valve is installed.Happy we did not have to call a plumber and would recommend the part and the ability to do the work ourselves. 5Just what I needed and timely delivery thanks to Amazon Prime. Like the other reviews you've read, I lost the hot water side of the original mixer. It's apparently true that you can get a warranty replacement from Kohler, but they're not going to get it to you as quickly as you need it when you shower more often that once every 6 weeks or so...So it was Amazon to the rescue. Would've cost more from a big box or a plumbing shop, if they even had one in stock.It was an easy fix, and works just fine. Love it when I can save a little $ by fixing things, myself... 5
