I was replacing an existing unit so the right lines were there
modifications can be a good thing or bad
shower sump was fine, but took 3 hours to install as the hose connections (shower, and 2 sinks) were not in the same place as the original shower sump (Also Attwood) and the hoses were cut for the old unit and it took some reconfiguring to get all the hoses connected to the sump box. Once on it worked great.
This was a direct replacement for a pump that failed. The new one simply doesn't work. When it does run, sometimes it pumps water, sometimes not. And when it does actually run and pump water, the pump won't shut off. I'm looking at other brands although the reviews I've read on the Rule pumps are just as bad.
Easy works great
Easy to install if you need to replace your existing pump. Works just like it is supposed to.
