Grohe 47111000 1/2″ Thermo-element Cartridge, Unfinished

Worked well in fixing the dripping leak on a 30+ year old Grohe facet in the house.

Old shower tap was no longer working, now it is easily adjustable and works great, asy to increase or decrease temp with out fear of burning yourself

Ersatzteil hat eine sehr hohe Qualität; genau wie das in den 80er Jahren war; passte hervorragend zu vorhandenen eingebauten Ware.

Leider hat das Produkt nicht gepasst. Ich habe es wieder zurückgeschickt aber dafür €14.- bezahlt.

Replaces pressure balanced valve when it becomes stuck or does not flow water temperature reliably. the holt and cold valves are usually okay (much less cost). Once you have the knob and handle assembly removed, the valve is relatively easy to replace, requiring a very large deep socket to remove. See the manual which came with the valve for an exploded diagram for disassembly. If your water exhibits significant hardness, scale build up internally around the threads may cause the valve to be stuck. I was only able to loosen the threads by using a 18" breaker bar to gently force it to loosen. Only a few threads engage the valve. Use a 6-point socket as the shoulder the socket rests on has a short length making soft brass easy to strip (I almost did using a 12-point socket). I was told by Grohe USA to use a 17mm socket which is far too small. The best fit I found was SAE using a 15/16" deep socket (if I recall correctly) and not metric, to get the tighest fit of socket to valve body. Also Grohe mentioned that applying clear vinegar in advance, letting it soak in, would help, though where to apply it seems would be a challenge, unless you remove the escutcheon plate. the silicone grease packet is hardly enough to cost the 3 o-rings. Any extra smear around the valve body to prevent scale build up of freezing the valve to its housing. The downside is this valve is very pricey.
