The Grohtherm 1000 was after a lot of running about and requests that the first (and only) choice. Reason: had been reversed in the shower of hot and cold water connection during installation. For such a problem hardly offers manufacturers a solution in the form of a mixer with 400 euros on, Grohe already. Emailed customer service and because it was also the solution for the Grohtherm 1000. A new thermostat compact cartridge (part number 47175 1/2 ") can be directly on the internet googling as well as the Grohtherm 1000 (at Amazon). Makes a total 200, as much as the fitting some manufacturers alone costs (without installation) The cartridge was easy to replace (a 34-helping-ended spanner while immensely) and now is a shower -. hot and without the usual burns of guests and children under the shower. The valve is well made, adjustments fall as good as gone, and now they just have to keep at least 10 years ;-)))
