Can’t wait for your Hansgrohe shower to warm up? Or perhaps it’s too hot, and you cannot understand why. If so, you should check the adjustment valve and adjust it accordingly. Here’s how the Hansgrohe shower valve temperature adjustment works.
Hansgrohe shower valve adjustment features two knobs; one for controlling the water temperature and the other for controlling the water flow. Turning the temperature control knob clockwise makes the water colder, while counterclockwise makes it warmer.
I’ll explain more about how the valve works, common Hansgrohe shower problems, and troubleshoot them. Moreover, I’ll explain how you can calibrate your Hansgrohe shower valve after trying to adjust it to no avail.
So, let’s get started!
How The Hansgrohe Shower Valve Temperature Adjustment Works
The Hansgrohe shower valve has an inbuilt thermostat that presets the water temperature and adjusts it to your preferred level. Usually, the valve has two knobs or handles as follows:
- Temperature control knob
- Water volume control knob
These knobs work as their names suggest. If you want to change the volume of your shower water, all you have to do is adjust the water volume control knob.
And if you want to make your shower water either warmer or colder than it already is, then the knob to adjust is the temperature control knob.
Note that these two knobs work independently. You don’t have to adjust the other just because you have adjusted one. In that case, you can change the water volume without changing its temperature or change the water temperature without changing its volume.
Overall, turning the temperature control knob clockwise makes your shower water colder, and doing it counterclockwise makes it warmer.
So, you can adjust the temperature control knob as much as you want without changing the water flow to achieve the correct water temperature to shower with.
Common Hansgrohe Thermostatic Valve Problems and Their Troubleshooting
While the Hansgrohe shower valve is easy to adjust and get the right water temperature, you should be wary of a few common problems which you can troubleshoot yourself.
They include the following:
1. Your Shower Water is Too Cold or Very Hot
If your shower water cannot warm or it drastically becomes hot enough to burn you, it means something is wrong with the Hansgrohe valve. In that case, the most sensible thing to do is to try and adjust the valve adjustment.
If that doesn’t work, it means you have a faulty thermostatic cartridge, which you should replace.
One top consideration is the Hansgrohe 94282000 Thermostatic Cartridge (View on Amazon). This thermostatic cartridge comes in a quality build and promises the best performance.
How to Replace a Hansgrohe Thermostatic Cartridge
Once you have the thermostatic cartridge, you’ll need a spanner and then follow these steps:
- Turn off the shower water first and heater
- Use the spanner to loosen the shower cartridge by turning it counterclockwise
- Do this slowly and carefully not to damage other valve parts
- Once you loosen the old cartridge, remove it and then slide in the new one
- Turn the shower water on to see if the water heats to your desired temperature
2. Your Shower Water is Trickling Slowly
The shower water usually trickles slowly when the pressure drastically reduces. Often, it’s a case of the Hansgrohe valve components wearing out and becoming defective.
In that case, you should replace the affected Hansgrohe valve components.
3. Your Hansgrohe Showerhead is Continuously Dripping
If your showerhead drips continuously even when the shower is not running, the chances are that the shower valve seal is worn out or just faulty. In that case, it’s a good idea to replace it with a quality rubber valve seal.
4. Your Hansgrohe Shower Valve Temperature Adjustment is Stuck
If your shower thermostatic valve produces a grinding sound when you turn your shower on or doesn’t turn at all, the chances are that it’s stuck and thus won’t work as expected.
In such a case, you should remove the valve cartridge and grease it before returning it. Overall, you’ll need these supplies:
- Crescent wrench
- Channel-lock pliers
Here’s how to go about it:
- Hold the valve housing tightly in place using channel-lock pliers
- Use a crescent wrench to pull the valve cartridge out by slowly turning it counterclockwise
- Once the cartridge is out, check for any blockage that could be making it stuck
- Unblock it and lightly apply some lubricant. You can use the DANCO Waterproof Silicone Lubricant.
- Now slide the cartridge back inside the valve and test it by turning the shower on
How to Calibrate a Hansgrohe Thermostatic Valve
Sometimes, even the above Hansgrohe shower valve troubleshooting ideas may fail to work, and the water won’t stop running too hot or cold.
If that’s the case, you should try calibrating the shower valve. Calibration is advisable when facing surprise hot or cold water splashes.
The process of calibrating your thermostatic shower valve is straightforward, and all you need is a hex wrench, preferably 2.5mm.
- Unscrew the shower temperature control knob (the handle) using the hex wrench
- Place a basin at the center of the shower and turn the shower on
- Place the shower control handle that you removed gently to the spindle, turning it counterclockwise half a turn with the help of the loosely attached handle
- Wait for a few minutes for the shower water to attain a maximum temperature
- If the water is still cold, you can turn the spindle half turn counterclockwise until it reaches your desired temperature
- Once the water achieves your preferred temperature, turn the shower off and screw the temperature control handle to the spindle using a wrench
- Turn the shower to test it and see if the calibration was a success
How to Replace Hansgrohe Shower Valve
Sometimes, the problem may be that your Hansgrohe is old. So, the only fix to such is replacing it.
Overall, replacing a Hansgrohe shower valve is simple. First, you need to check the actual size of your shower valve.
Though most thermostatic shower valves have the same installation standard, it’s always a good idea to confirm the size before buying a replacement.
One thermostatic valve worth considering is the 2-Handle Thermostatic Shower Valve (View on Amazon). It has the US standard fitting and is sturdily built with brass material to last you longer.
Here are the supplies you need to replace a thermostatic shower valve:
- Dry cloth
- New thermostatic valve
Step 1: Turn Your Shower Water Off
Before anything, you should turn your shower water off. You can do this by turning the shower handle clockwise.
But if you are dealing with a leaky shower valve, you may need to turn the water off from your main house water supply.
Step 2: Lay A Dry Cloth on the Floor
Laying a dry cloth on your shower floor prevents your screws and smaller shower parts from going down the drain. Plus, it keeps your working area clean.
Step 3: Remove The Shower Handle
Using a screwdriver, locate the bolts that hold the shower handle to the wall and unscrew them carefully to prevent them from running down the drain.
Step 4: Remove The Valve Cartridge
Using pliers, pull the shower cartridge slowly. The cartridge is usually u-shape.
Once you remove it, disconnect the Hansgrohe thermostatic system from the water feed.
Step 5: Fit the New Thermostatic Valve
Slide the new thermostatic shower valve and connect it firmly to the water supply system. Ensure that everything goes back to its place and turn on the shower to detect leakage.
Once you confirm there’s no leakage, adjust the water control knob to see if the water heats up to the desired temperature. If it does, congratulations! The Hansgrohe shower valve installation was a success.
