About the Crosswater Sol compatible thermostatic cartridge assembly GP0012174 / RV1102RC A wax capsule can be found inside the Crosswater GP0012174 / RV1102RC. The capsule is responsible for water temperature regulation by counterbalancing the flow of hot and cold water to generate a preferable temperature. Is your Crosswater thermostatic cartridge assembly GP0012174 / RV1102RC broken? Thermostatic cartridges can break down for several reasons such as debris buildup or inconsistent supply of hot and cold water. The cartridge will need to be replaced if it is unable to control water temperature. This is one of the ways to know if your Crosswater shower thermostatic cartridge is showing signs of failure. Manually Testing a Wax Capsule Materials Needed: 1 small cup of hot water 1 small cup of cold water Wax cartridge capsule Marker Note: Please do not pull the piston out of the wax capsule. To see whether a wax capsule is in excellent working mode, or if it is time to discard it, please follow this simple test. The test is not infallible but will give a conclusive answer in most instances. 1. Hold the wax capsule at the tip of the piston. Dip it in a small cup with cold water for a few seconds until its temperature drops. 2. Pull it out of the water and use a felted marker or pen to mark the point on the piston where it came out. 3. After marking the piston, dip the capsule in the cup of hot water. The piston will involuntarily push upward as the wax inside expands. The piston will raise three to four millimeters. 4. Take it out of the hot water and dip it back in cold water to let the temperature fall. 5. Take it out of the cold water and try pressing the piston down. If it goes back in the capsule, the wax capsule’s thermostat is functioning well. Do you need the wax thermo-element? - We have a range of wax thermostatic elements suited for mixer showers.
