How to Troubleshoot a Thermostatic Shower How to Troubleshoot a Thermostatic Shower
A thermostatic shower has a pre-set thermostat that will sense a dramatic change in temperature and correct it avoiding extremely high temperature for the user. Some thermostatic showers will even cut water source off when there is a problem detected. This is perhaps one of the best options you can install in your bathroom without having to worry about water being too hot because inside is an automatic adjuster that maintains temperature by adjusting the flow of each water supply. One way that a thermostatic system works is that, for example, when the water temperature starts to go down, the system will lessen the flow of cold water to balance the temperature. The same works for hot water flow so that scalding can be avoided. This type of thermostatic shower is dependent on water pressure created by the hot water. Certain problems do arise and must be addressed to ensure proper functioning of this type of showers. Here are some ways to troubleshoot problems with your thermostatic shower.
Step 1 - Check for Dirty Valves
To fix this, valves simply have to be cleaned. Remove the valves and inspect it. When calcium deposits from the water start to build up and clog the whole on the showerhead. Because of this, the pressure changes and this could affect the regulator sensors and the result is inefficient regulation of water temperature.
Step 2 - Check for Reversed Water Supply
The valve has to be inspected because the valves might have been placed in reverse. Check if the hot water supply is correctly draining into the “hot” valve and the “cold” water into the cold valve. This problem could have been done upon installation. Make sure the valves are in their proper position before letting family members use the shower.
Step 3 - Check Possible Reversed Installation of Valves
To fix this, simply reverse the valve the correct way.
Step 4 - Check Water Pressure
Check for lack of water pressure in one of the inlets. To fix this, the water pressure has to be fixed. You owner’s manual will have this information and will depend on the model and brand of your thermostatic shower.
Step 5 – Check Showerhead
Showerhead can become blocked by dirt and debris. To solve this, heat enough water to soak the whole showerhead. Mix 1 part warm water 1 part vinegar in a bucket and soak the clogged showerhead in it. It will help if you use a soft bristled brush on the showerhead to loosen all dirt and debris. Test the showerhead after. Observe if all holes on the head releases water. If not, keep brushing until all holes are unclogged.
Step 6 – Check Calibration of Valves
Check if valves may not have been properly calibrated. Calibrate your valves by looking into your owner’s manual. Calibration technique will differ depending on the brand and model.
Step 7 - Check for Incorrect Water Settings
Simply adjust water heater settings.
