If there is moisture, the sensor port or immersion sleeve will need to be replaced. This is mostly a problem in the older stainless steel hot water tanks. The original sensor port develops pin holes because it is the weaker metal. \u003c\/p\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eSensors are not designed to be installed in water and the moisture gives them an inaccurate reading. If you find moisture, check the roof sensor and the circulation pump first before ordering a tank sensor. Just because the pump motor is running does not mean it is circulating water as it should. With some models of solar hot water systems, your best option may be replacing everything at once with a complete pump station. Please contact us if you have questions about this before you purchase this item.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eIt is important that tank sensors are not used as roof sensors. Tank sensors are normally made from PVC cable and not high temperature silicone cable. Tank sensors are generally only rated to 90 degrees, whereas roof sensors can be rated two to three times higher.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eNot all sensors are the same. This is a common mistake because over the years some manufacturers changed controllers multiple times. The thermistor inside the sensor gives different resistance levels with temperature change and the controller uses the reading to calculate the differentials required to operate the circulating pump.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eThere are many different types of controllers that use different types of sensors.
