Location: US, NYC. I am doing a partial renovation of a small kitchen in a 2-family house, and trying to keep the cost down if possible. Plumbing done, cabinets and backsplash installed, countertop and sink are coming soon. At this late stage, I've discovered that NYC recently allowed garbage disposals (I always thought they were illegal), and I'm wondering how feasible it is to add one.
The setup is on the diagram below. Questions:
- There is an approximately 2 foot long approximately horizontal drain pipe run (usual 1.75 inch PVC) between the vertical drain line and the P-trap. Most of this pipe is behind drywall and cabinets and cannot be realistically changed at this stage. Would a garbage disposal be strong enough to push waste through, or would things get stuck in the horizontal pipe?
- And what if the pipe is not quite horizontal, but slopes slightly?
- Are there height restrictions for where the garbage disposal's output should be in relation to the P-trap and the horizontal drain pipe?
- The P-trap is under the center of the sink, but my sink model drains on the right side. Are there any restrictions on the shape or type of the drain connection from the garbage disposal to the P-trap?
- There is no dedicated switchable electric outlet under the counter for a garbage disposal, so I thought of plugging a wireless garbage disposal switch into the same double outlet as the dishwasher. Bad idea? Otherwise, the wiring job would be a bit complicated and would require breaking the backsplash.
- Generally, does anyone have experience with garbage disposals in NYC?
