That one is being repaired and kept on hand as an emergency back up pump

So far so good - I guess I will find out in years to come (hopefully) how durable this is

So quiet don't even know when it's running

The replacement pump was tested and appeared to work fine, but once installed, it failed on the very first time it was needed

When the switch was manually triggered it activated the pump, but did not deactivate the pump once the water level fell below the float activation level; the pump continued to run until it was unplugged

The first one came with a bad switch
