Hello,
I don’t understand what you mean by "collar" regarding the fittings.
What type of hot water system do you have?
Do you have a solar system for hot water production?
Have you installed a mixing or anti-scald valve?
Please provide more information about the system.
Regards, ALMI

Hello Almi,
We have a solar-assisted hot water system. For this, we had a 400-liter (105-gallon) water tank installed. The company Wolf explained to me by phone that the hot water only comes from one pipe, located at the very top of the tank. So, their argument was that if the problem were related to the hot water supply, all outlets should be affected. However, as I said, only one shower is affected, while the temperature remains stable in the other.
By sleeve, I mean the metal ring that is attached where the hot water comes out of the wall. We have a surface-mounted thermostatic mixer, which means on the left you can select whether the water comes from the overhead shower or the handheld shower, and on the right is the temperature control. This can be set to lock at 38°C (100°F). This is stated in the product description:
Hansgrohe Raindance Showerpipe consisting of:
Thermostat AP with shut-off/diverter valve,
Raindance AIR overhead shower Ø 24.0 cm (9.4 inches) with Rubit anti-limescale system,
Raindance S100 AIR 3-jet handheld shower with Isiflex 160 cm (63-inch) hose
and height-adjustable shower holder.
Suitable for instantaneous water heaters, if the flow pressure before the fitting is at least 0.15 MPa.
I would be very grateful for any tip on what might be causing this!
Best regards
Katharina

Hansgrohe Service23 Jan 2012 13:02Hello Katharina,
I am from the service team at Hansgrohe AG and found your question here.
From your description, it seems that a check valve is defective in this bathroom or on this pipe run, which is causing cold water to be pushed into the hot water line, or vice versa. In the shower, the issue might be due to dirt getting into the check valve. My suggestion: simply check the check valve and test its function.
If the problem continues, feel free to contact me by phone at 07836511282.
Best regards,
Günther

Hello everyone,
Mr. Schmidt’s suggestion is not bad, but personally, I would consider it a secondary option.
First, I would check if there is a flow restrictor installed between the shower hose and the handheld showerhead or showerhead, and try removing it temporarily.
It is also possible that the temperature preset on the faucet is not correctly adjusted.
Additionally, if there is a premixing valve (scald protection due to solar heating), it might be faulty or not working properly with the thermostat in the shower faucet.
Perhaps Mr. Schmidt can provide more input, as he probably has more expertise with faucets.
Remote diagnoses can be quite tricky.
Best regards,
Almi

Hansgrohe Service24 Jan 2012 09:32Hello Katharina, hello Almi,
I don’t believe the issue is related to water-saving devices or a reduction in pipe diameter. I also rule out the temperature presetting and the premixing valve, since the problem described involves different faucets with different mixing systems.
Checking the check valves is not difficult and can be done quickly with a few simple steps.
If there are problems with the check valves, just give us a call, because then we would need to find out whether it is a surface-mounted thermostat or a concealed thermostat.
