There are numerous signs of hot tub pump failure. Malfunctions that put off the motor from turning, including frozen shaft or bearings, may result in a humming noise. A jammed impeller can do the same, as can a faulty starting capacitor. Badly worn bearings may lead to a whining noise. Leaks around the pump often point to a failure of the pump seals. You will probably observe a puddle of water below the pump when these seals go badly. In addition, our patented hot tub pump shroud vents heat from the gear compartment. This creates a cooler working environment for the motors and electronic components, causative to a longer life for your Hot Spring spa. More about the hot tub pumps In most hot tubs, the jet pump has to undertake double duty, powering the hot tub jets at high speed and the spa filtration cycles at low speed. To give you with a soothing massage experience and continuously filtered water, a Hot Spring spa divides the work between the high-powered Wave master jet pump and our split, low-amp, SilentFlo 5000circulation pump. The Wave master jet pump is devoted to delivering the finest massages experience by producing a powerful flow through all the jets. And with an self-governing circulation hot tub pump you can enjoy the powerful jets and soothing water features, and still be assured of clean, heated water, 24 hours a day. While all Hot Spring spas are influential, our High Performance models have even higher horsepower pumps to power additional jets and water features. Conclusion Hot Tub Heaters take a lot of mistreatment. From the moment a spa is turned on, hot water and sanitizing chemicals are constantly rocketing through the heater. Industry surveys show that heaters are generally the first part of a spa to fail. It?s no surprise, since most heaters are made of stainless steel, which makes them exposed to the pitting and corrosion fatigues that lead to problems ranging from heat loss to complete system failure. That?s why Thermo-Spa builds spa heaters stronger, with one of the most excellent and strongest metals known to man - Titanium. A few spa manufacturers use Titanium in their heaters, but they cut costs by making only the heating coil out of this nearly indestructible metal. Thermo-Spas heater, coil and surrounding jacket are all made of Titanium, so the entire heater is resistant to chlorine pitting and practically impervious to corrosion and cracking, which is why Thermo-Spas heaters not only last years longer, they are also backed up with a much superior warranty.
