John Dirks Jr Posted November 18, 2009 Report Share Posted November 18, 2009 I thought this looked wrong. What say you? Are you aware of any manufacturer instructions or code language that supports it being wrong? I'm thinking it would at least slow the rate of evacuation and maybe put some extra stress on the pump due to pressure caused by the restricted discharge line.

I seem to remember at least one sump pump manufacturer (Zoller?) used to say that you had to use a discharge line that was the same diameter as the tap on the pump. I don't have the reference handy, though. - Jim in Oregon Quote Link to comment Share on other sites More sharing options...

It'll definitely reduce volume but I think you'd find that the pump would draw more current if the discharge were unrestricted. It'll work longer, not harder. Positive displacement pumps excepted. No matter what, it's just dumb, right? Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted November 18, 2009 Author Report Share Posted November 18, 2009 It sure looked dumb. Especially since the garden hose disappeared beneath the grade so I could not see where it went. It was written up. Quote Link to comment Share on other sites More sharing options...
