GROHE 47439000 Bath Accessories Bathroom-Sink-Faucet-Replacement-Parts

It was the exact part I needed.

Mijn lekkende kraan is hiermee weer helemaal als nieuw. Echter niet zo simpel om na 20 jaar de oude los te krijgen, maar nu dus weer gemaakt!

Impeccable . Bien graisser avant de mettre en place.

Acquistata per sostituire la precedente guasta, funziona benissimo e modula velocemente per mantenere costante pa temperatura dell’acqua.

Lässt sich leicht tauschen (5-10 min. max.), 34er Schlüssel oder Rohrzange benötigt. Ich habe den Ring vorsichtig mit der Rohrzange gelöst und wieder fest gezogen, war kein Problem wenn man etwas Gefühl hat. Ansonsten tu was er soll, Temperatur einstellbar. Der alte Thermostat hat 9 Jahre gehalten.

There is nothing wrong with this good quality product but the following might help someone else avoid the mistakes I made. First, check the strainers. I put poor hot water flow down to a failing thermostat. In fact, I now know the hot supply strainer was full of scale debris. I removed as gently as I could the cartridge retaining ring with a pair of water pump pliers as I didn't want to cough up what Grohe was asking for their proprietary tool. This was a bad move as the fragile ring distorted slightly and I then couldn't get the fine thread started to reinstall it. So, if you're doing this job, you will need to have either a good quality flat or ring spanner, or the Grohe tool. (The ring, if you mess it up, costs around 30 GBP)
