It is the same part in either position. Where you mount it decides whether it reads air, water or solar. Order one per position you are replacing.\u003c\/p\u003e\n\u003ch3\u003eCan I extend the cord if 15 ft will not reach?\u003c\/h3\u003e\n\u003cp\u003eNo. Jandy says to cut and discard excess rather than splice or extend. Splicing changes the resistance the controller reads and skews the temperature. There is no OEM extension.\u003c\/p\u003e\n\u003ch3\u003eHow do I know the sensor has failed?\u003c\/h3\u003e\n\u003cp\u003eA reading stuck on one value, an impossible reading, dashes on the display in place of a temperature, or a heater or solar valve that will not call because the controller thinks the target is already met.\u003c\/p\u003e\n\u003ch3\u003eWill it work with my Polaris S20?\u003c\/h3\u003e\n\u003cp\u003eYes. The 7790 is the published direct replacement for the Polaris S20 sensor.\u003c\/p\u003e\n\u003ch3\u003eIs this the same as the cheaper sensors sold online?\u003c\/h3\u003e\n\u003cp\u003eNo. There is a large aftermarket in generic probes sold as 7790 replacements. This is the genuine Jandy part with the factory thermistor calibration your controller expects.\u003c\/p\u003e\n\u003ch3\u003eHow is it installed in the pipe?\u003c\/h3\u003e\n\u003cp\u003eDrill a 3\/8 in hole between the pump and filter, seat the O-ring against the pipe wall and hold it with a stainless clamp. Do not overtighten, excess clamp pressure cracks the probe boss.\u003c\/p\u003e\n\u003ch3\u003eDo I need a professional?\u003c\/h3\u003e\n\u003cp\u003eThe sensor is low voltage and within reach of a capable owner, but it lands inside a power center that also carries line voltage. Cut power at the breaker before opening the enclosure and have a licensed professional handle anything on the supply side.\u003c\/p\u003e\n\u003ch3\u003eWhat is the warranty?\u003c\/h3\u003e\n\u003cp\u003eStandard Jandy manufacturer warranty.
