In the name of efficiency, we wanted to pour the concrete for the floors at the same time as pouring the remainder of the rainwater collection system. But before we could do that, we had to lay the in-floor plumbing (the drainage system).
Please support our mikvah project, with either a one-time donation (using the progress widget to the right) or recurring monthly donations (above the progress widget). For dedication opportunities, please contact Rabbi Rabinowitz. All donations are tax deductible.
The trough dug through what used to be the men's locker room, for laying the mikvah's main drain pipe that will tie into the trunk line for the basement.
The trunk line (vertical, right) exposed. It needs to be cleaned of debris and a section sawed out, to insert the tie-in.
The trunk line with the new tie-in. It angles 45 degrees in the direction of the flow to prevent clogging at the site of the connection.
The main drain pipe, coming into the mikvah area, already connected to the trunk line.
The drain pipes branching off from the main line towards the main preparation room.
More branching out; towards the laundry room and the secondary preparation room. Note how the pipes are bolted to the floor; this is to maintain them at the exact height to keep the perfect 1/4" pitch. The pipes won't move now, even when the concrete is being poured.
All of the in-floor plumbing is laid. Now we're ready for back-filling!
