KohlerGENUINE PART GP77759 MIXER CAP FOR PRESSURE BALANCE 1/2" SHOWER VALVE

ممتاز جودة عالية

It took me a month to install this product. Although I watched how to do it in Youtube, at first, I was still hesitant to install it because, I thought it would be complicated... I almost called a plumber. But it was a very simple installation.... I even learned to assemble and disassemble this product, using the old one that I replaced. As a matter of fact, the old one was not really broken... the leaking was caused by the displacement of the washer for the cold water and for the hot water not coming out all the time, it was the spring that was displaced. I cleaned the whole unit, greased the springs and washers and it's all good !! But of course, I am now using the new one.

Si funciona muy bien recomendado

01/30/15 UPDATE===============Since the original review, I've since replaced the mixer cap in our other two showers.I've grown to have a serious love/hate relationship with this part. I love it because it constantly fixes the problem where you barely get hot water. I hate it because the failure rate (especially in showers that ARE NOT used often) seems to be astronomically high -- unquestionably, I've now spent north of $200 on replacement mixer caps and pressure balance units over the past decade.In my most recent replacement, the failing cap literally fell apart as I unscrewed it from the brass valve housing, just like last time. Unbelievable.I can now safely say it is worth keeping one of these and a pressure balance unit on-hand -- there's a near-100% chance you will need them at some point.===============ORIGINAL REVIEW===============I was having an(other) issue with one of our Kohler shower faucets where hot water would only be dispensed if the handle was turned to the end of its' range of travel, at which time the overall pressure dropped significantly.After cracking open the handle assembly and making some tweaks to the anti-scalding collar (to no avail) I decided to order both this mixer valve and the pressure balance cartridge I had replaced in two other Kohler assemblies in our home.Once the parts came (thank you, Prime), I pulled the original mixer valve out and it, more or less, came apart in my hands. I re-seated the O-rings in the pressure balance cartridge and reaffixed the mixer cap to the brass housing. I turned the water back on for a test and sure enough, it was working perfectly now AND with better pressure than before. Bonus. Ten minutes later I had everything reassembled and re-caulked. Job done.I'm considering keeping one of these as a spare since the guts of these Kohler fixtures seem to fail with such regularity.If you're having any sort of issue with your Kohler fixture, chances are it's either this or the pressure balance cartridge. Buy them both and you (probably) can't go wrong.I'm on the handy side, so replacing this for me was not a big deal. If the thought of turning off your water supply or getting a little wet scares you.. best to have a friend handy who has done this kind of thing before :)

This part fit perfectly and there were no leaky shower head after replacing with this.

This is a perfect fit for my Kohler shower faucet at a fraction of the price elsewhere. Installed and tested for weeks, no leaks! Would purchase again...but I hope I don't have to 🙂
