Finalizing sump-thing

I am working down the list of plumbing connections I have to make to the new sump pit. Those that require digging or moving soil are done.

The connection for the exterior footing drains is in place. I also have the interior footing drains connected, and so is the sump discharge into the sewer, although it is a temporary connection at this point.


Plumbing per code

To turn the temporary sump discharge into a permanent one, I need to switch out the Schedule 40 PVC piping with Cast Iron Soil Pipe (CISP), as per the Chicago plumbing code requirements. I have to use CISP where the pipes are concealed, i.e. under the future floor slab. Once I am in the sump pit, I can re-connect to the already installed PVC pipe setup.

I got myself the right CISP pipe, fittings and gaskets, widened the hole into the sump to fit the two inch CISP pipe, and made the new connection.

Sewer extension

When we ripped out the old sewer to replace it, the City required that I separate the sanitary sewer line from the storm sewer line .

To extend that line, I bought a four inch diameter CISP pipe and took it all the way to the porch footing. Once the porch gets torn down and the footing is redone, I will continue to extend that line into the back yard.

I may never connect a downspout to that storm sewer line, as I have ambitious plans for sustainable and infiltration based stormwater management in the yard. Instead, that storm sewer line may be repurposed into a sanitary sewer one day — if we ever build a garage with a studio apartment above it. But those are distant dreams and warrant a whole new blog post.

Cistern connection

I have a couple of connections to go, and one of them is the future discharge connection to the underground cistern (see also graphic above). This requires another hole to be punched into the sump pit through which I can fit the pipe. Because this is not part of the sewer plumbing system, I used a Schedule 40 PVC pipe for the rough-in and will again extend it into the yard once we redo the porch footing.

Electrical conduit

The cover for the sump pit will be in the middle of a workshop area. I wasn’t interested in having power cords from the pit cover running across the floor; I’d rather avoid that kind of trip hazard. And I did so by installing a 1 1/2” diameter galvanized electrical conduit from the pit up to the basement wall. I can have an outlet near the top of that conduit, and thus circumvent the power cord spaghetti sprawl.
