Pump relay
The general concensus is turning a pump on and off with a relay is bad news, and the reasoning is good. What I want to know is who has had a pump die on them due to this (I know you can't prove it for sure), especially if it was a higher quality pump such as Eheim or Danner. No doubt the life of the pump is shortened... but if it goes from 10 years to 5... well, you get my point.
