GROHE 46048000 | Cartridge

After about ten years the cartridge in my Grohe Minta Touch tap failed. This cartridge arrived quickly (next day) and restored the main mixer in my kitchen to full functionality. It was a breeze to install (one allen key and one phillips screwdriver required to install in my case). And I have the peace of mind of using a quality part. I just hope this one last as long - or longer - than the original.

A genuine Grohe replacement part...fits & works perfectly, as expected.Product description is misleading as this component is 35mm. ( The 46mm referred to in the description possibly refers to the tap body diameter.)

Next day delivery to the north of Scotland! Excellent product, simple to fit and reasonable price, assuming it lasts ten years, like the last one. It would be useful to include a replacement Allen bolt cover (plastic and easily mashed when removing) but otherwise very good.

The lever on my Grohe Touch shower valve had been getting stiffer & stiffer recently, which is a bit disappointing, as it's less than 5 years old. Rather than replace the entire valve, I decided to replace the cartridge, which costs about 1/3 as much as a new valve. The most difficult part was removing the lever. After taking out the rubber plug, the grub screw can be removed using a 3mm Allen key. I pulled & pulled at the lever, but it wouldn't budge. In the end, I sprayed some WD-40 into the screw hole, and let it work for an hour or two. Then, I placed a wooden wedge between the top of the lever and the tap body, and by pulling on the lever, it eventually came off. You need to be careful, as the plastic domed cover under the handle can easily be damaged. After this, the domed cover can be carefully flipped out, exposing the front of the cartridge. The cartridge is simply held in place by 2 Philips screws. Having removed the old cartridge, it's a good idea to clean the flange area at the back of the tap to get rid of any limescale or other deposits.The new cartridge comes with a few extra bits, presumably for other models of tap- an extra plastic lever adaptor, a round plastic ring, and some extra-long screws. The instructions explain what these are for. It's very simple to fit the new cartridge, but it's important to make sure it's seated properly with the silicone gasket sealing against the waterways, or you'll get leaks. The metal plate goes over the front, and the cartridge is secured by tightening the screws. After fitting the domed plastic cover, the lever can be slipped onto the spindle & the grub screw tightened. I smeared some silicone grease over the spindle & plastic adaptor, to hopefully make it easier to remove next time. The valve now operates much more smoothly, and doesn't stick.I'm very pleased with my purchase, although a little disappointed that the original cartridge failed so quickly in the first place. Also, the delivery time from Amazon was a little slow at 5 days. I've knocked a star off for those reasons. Otherwise, I'm (hopefully) looking forward to at least another 5 years of trouble-free service from my valve.

In stock, less expensive than other sellers, UK based seller. Time will tell how the replacement cartridge will do. As headline says, I bought this for a Quadra XL size basin mixer tap. It was the same fitment, just the colour is different (new one is blue casing, original is tan).

Seemed expensive, but works perfectly. Came with a useful exploded view.

Perfect replacement.

Sorry but this part arrived, my plumber fitted it and it was faulty / leaks worse than the one it is replacing. So surprised as previously I’ve always been impressed with your service. I have returned the product and now have to wait for its replacement. I then have to get my plumber back to fit it.
