John Dirks Jr Posted September 2, 2012 Report Share Posted September 2, 2012 The picture shows discharge and vent pipes of an ejector pump that serves a basement bathroom. The ejector discharge pipe is the one on the right. I know that is incorrect since it goes into the bottom of the main drain line. That main drain line serves in upstairs hall bathroom including toilet shower and sink. The line on the left from the ejector pump is the vent which loops into the top of the main drain line. My question is this. Is it acceptable to wet vent an ejector pump such as what was done in this picture? Again, I know the discharge line is wrong and that's getting written up.

kurt Posted September 3, 2012 Report Share Posted September 3, 2012 No, there should be a 2" branch vent from the ejector eventually venting to the exterior. Quote Link to comment Share on other sites More sharing options...
ericwlewis Posted September 3, 2012 Report Share Posted September 3, 2012 That's a good question. It all looks jack-leg to me. wouldn't the pump be working against itself with this configuration? Quote Link to comment Share on other sites More sharing options...
Scottpat Posted September 3, 2012 Report Share Posted September 3, 2012 Did you see a real vent line or is it just the pseudo vent line from the grinder pump? I would not even call that setup a "wet vent". Quote Link to comment Share on other sites More sharing options...
kurt Posted September 3, 2012 Report Share Posted September 3, 2012 Neither would I. It's a total bollix job. It should all come out. Quote Link to comment Share on other sites More sharing options...
John Dirks Jr Posted September 3, 2012 Author Report Share Posted September 3, 2012 You can trust me, I wrote it up. It looked pretty bad on the bottom end too. Here's a specific question. Can the check valve be laying on its side? Is that ok? Click to Enlarge 43.59 KB Quote Link to comment Share on other sites More sharing options...

All I have seen are further up on the line and I have never seen one horizontal. I have no idea if they work on their side, but I doubt the manufacturer of it approves it for that type of install.

ericwlewis Posted September 3, 2012 Report Share Posted September 3, 2012 I have had the pleasure of installing several of these lately and the typical check valve instructions indicate it must be installed horizontal or at a 45 degree angle so that solids cannot block the valve. In addition, Indpls now requires a stop valve above the check valve for maint. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted September 4, 2012 Report Share Posted September 4, 2012 There should be a skill-testing questionnaire for people who want to install their own sh$t pump. It's obvious the instructions were a waste of paper here. Quote Link to comment Share on other sites More sharing options...
