Bypasses are typically found around ~s, exhaust fans, chimneys, attic hatches, wall/ceiling framing joints, wiring and lighting fixtures. Use silicone caulk, poly plastic as fill material, foam sealant or a combination of all three to stop air flow around these areas.

Shown here is also the old sewer ~ to the right. The new second/third floors would receive brand new plumbing.
