After only 3 years since replacing our submersible envirocycle septic pump it has failed again! Unfortunately, these pumps only come with a 2 year warranty and my service guy reckons the manufacture expects submersible pumps to die between 3 and 7 years, which is absolutely ridiculous! At $850 who can expect to afford a new submersible pump for their septic every 3 years? Previously, my old pump lasted 15 years back to when our house was built and in the good old days when they manufactured stuff to last. When we replaced it the pump was hardly recognisable as it was so corroded but it worked. This last pump was practically new yet had "motor burn out" at just over 3 years (one year out of warranty) - I'm not happy and I let my service guy know it.
