* WAYNE Water Systems’ Exceed an Average 1 Million Test Cycles. 

WAYNE Water Systems is proud to report that our pumps have exceeded an average life of 1 million pumping cycles during rapid cycle test conditions. The testing was conducted by a nationally recognized, independent accredited testing laboratory and the results were subsequently analyzed by an independent, world renowned, reliability expert who specializes in failure analysis. The rapid cycle testing was conducted using a statistically significant sample size of 1/2 HP submersible sump pumps. Note: a highly accelerated test such as this may or may not reflect actual conditions that the homeowner would experience.
