To Vent or not to vent


A normal sump pump (for the purpose of removal of ground water around the footings and under the slab) will be visible in a pit in your basement...The pit has a removable cover.

An ejector pump will appear to be a contained unit, with a very solid lid usually bolted or screwed to a very solid housing.

Bkeech,

KC is right about the sump pits. I was referring to the possibility that the original contractor used a lower priced pump since it was only servicing a floor drain. After thinking about it, that's probably very unlikely. Go with thekctermite's descriptions and you should be fine.

To Vent or not to vent


I checked my city and they have adopted the IL 2004 Plumbing code. I found this on the web:

Section 890.1530 Pneumatic Ejectors

An air pressure relief vent from a pneumatic ejector shall not be connected to the regular venting system but shall be connected separately to the outside atmosphere terminating as required in Section 890.1430 for vent extensions through roofs. Such relief pipe shall be of sufficient size to relieve air pressure inside the ejector to atmospheric pressure within ten (10) seconds, but shall not be smaller than one and one-half (1 1/2) inches in diameter.

So I wonder if this means that I cannot connect my lavatory to the ejector vent?

That is exactly what it means.

Glad you checked. Sure wasn't trying to mislead you!

If venting the lav is an issue, you might ask the local inspector if they'll allow a Studor vent. They aren't the best case way to do things, but they sure do make it easier.

To Vent or not to vent


Something just clicked in my head. You see there is a vent pipe coming out of the concrete right next to the water heater. I think it is the vent for the floor drain. Can I tie into that? Its not far away, its about 6 feet on one wall, then turn and 4 feet on the other wall.

Thanks,
Bryan

Bryan,

Once again, the code you reference is concerning a Pneumatic ejector. This is a very specific type of ejector which runs on air pressure. If you have a Pneumatic ejector in your home you will be the first person I have ever seen with one and you would have to have an air compressor and air lines running to the ejector. I know that some inspection departments may routinely apply this requirement to all ejector pumps but, according to at least one official Code Commentary, that is not the intent of the Code and there is no functional reason to do so. If you want to be sure how this is interpreted in your city, call the Inspection Department early in the morning and ask to speak with a Plumbing Inspector. They should be able to tell you how they want it.

Yes, I will be seeking the help of my building department, as I intended to do this basement finish all legal.

So maybe its just an ejector pump?

My ejector pump looks just like the one in this post:

I called my cities plumbing inspector and he said I could tie into the ejector pump vent as long as the tie in is to code.

Thanks Everyone.

Check out my project in project showcase and i'll post updates on what I ended up doing.
