hansgrohe88585000 TB-1 Thermo Cartridge, Small, Chrome

This fixed our shower. One day we noticed it was starting to drip all the time. Two weeks later it didn't get as hot as usual. Then it started leaking inside the wall. There were individual shutoff valves on both inlets though, which was helpful. 4mm allen, quarter turn valves. I have hated this shower valve since we bought this house, it was always very stiff and the temperature adjustment was virtually impossible to turn. With the new cartridge it works smoothly and the temperature adjustment works. $150 is more than a whole new Delta shower kit, but I didn't want to deal with trying to cut the pipes, etc with the shower tile intact.

Easy install

I purchased this and the description said like new. It was broken but I could not verify until my plumber was able to secure the part from Hansgrohe and prove the one I had was defective. They were back ordered so I was without 1 working shower for a while which sucks. I would like my money returned even though it is outside the window, sometimes other circumstances require it.

Exactly what was need to repair the mixer. Just had to slightly file down part of the plactic housing in order for the cartridge to fit properly.

This cartridge ultimately worked for me, HOWEVER, if you have an older valve rough (i.e. one that is perfectly round) you will need to file-off the little plastic "bump" on the top of this cartridge in order for the cartridge to fit in the rough. Apparently, the newer roughs have a groove for the hump to slide into. The older roughs, like mine do not. DO NOT file of the "stub" at the base of the cartridge, just the little round hump. I spoke to someone at Home Depot who offered some great advice - use a fine metal file to file down the plastic hump and use blue painter tape to tape around the hump so that you don't scratch the metal. It will work - just take your time. Good luck!

Took the bad cartridge out put back in this new cartridge in, that is all it takes to fix the water leaking problem. German product quality.I received the second cartridge for another shower room, will install it shortly. I have confidence it will work very well.

Saved my shower.

Last one I just replaced lasted for more than 15 years. This is a great product, i love the increased pressure of water especially if your shower head/s (i have two installed) and handheld shower come with different features.
