Changing the layout of your kitchen can make day-to-day life easier, but relocating the sink often brings surprises once we open the walls. In Skokie, many homes were built between the 1950s and 1970s. That means decades-old supply pipes, original drains, and quirks common with older plumbing come into play immediately. Before you plan to move your kitchen sink across the room, make sure you know what's involved below the surface.
What Relocating a Sink Involves
It's not just a matter of running new flexible hoses or moving a cabinet. The plumbing under your sink connects to your home's entire drain and vent system, and each part must meet code. You'll need to reroute both water supply and drain lines, plus adapt the venting so everything flows properly. In some Skokie homes, especially those with slab foundations or finished basements, getting to these pipes can be tricky. Heavy clay soils and high water tables in this area make proper drainage especially important, since even small mistakes can lead to slow drains or leaks inside the walls.
Hidden Problems in Older Skokie Plumbing
Much of Skokie's housing stock includes galvanized steel or cast iron for supply and drain lines. Both materials corrode over time and can be brittle when disturbed, increasing the risk of leaks once you start moving pipes. Clay-tile sewer lines, still common in the area, sometimes suffer from tree-root intrusion or settling, which can complicate new drain tie-ins. If you're planning a kitchen remodel, this is a good time to look for signs of corrosion or to upgrade aging lines before you enclose them behind new cabinets or tile.
If your home has a basement, you'll want to look for any past water issues, especially since our flat terrain is prone to seepage. Relocating a sink may require you to tie into drain lines close to the foundation wall, where moisture problems sometimes lurk. In these cases, adding or checking your sump pump is wise. We often pair sump pump services with major kitchen or laundry renovations for this reason.
What to Look for Before You Start
- Pipe material: Are your supply or drain lines galvanized, copper, cast iron, PVC, or something else? Each has different risks during remodeling.
- Vent location: Is your kitchen vented through the roof, or does it tie into a larger stack? Proper venting is key to quiet, reliable drainage.
- Access: Is there unfinished space below the kitchen floor, or will pipes run through finished ceilings or concrete?
- Fixture spacing: Is your proposed sink location close enough to tie into existing water and drain lines, or will you need major rerouting?
- Permits: Will your project require a plumbing permit under local Skokie or Cook County codes? Most do if you're moving major fixtures.
Drain and Vent Challenges
Modern kitchen sinks require a minimum 1.5-inch drain with a vent to avoid slow drainage and gurgling. In older homes, we often find undersized or partially blocked drains. If you're moving the sink far from its original location, the new drain must slope at least 1/4 inch per foot toward the main line, and you can't exceed certain distances without adding a new vent or AAV (air admittance valve). Clay soil and flat, compact lots mean there's little room for error, improper slope or venting causes frequent clogs or even backups. We check for blockages and, if needed, recommend professional drain cleaning first so your new pipes aren't emptying into an already sluggish system.
If your main sewer line is older clay-tile or cast iron, this is the right time to assess its condition. Problems here might not surface until much later, but tying in new fixtures to a questionable line is asking for trouble. Our sewer line services can scope or repair main lines while the walls and floors are still open.
Tips for a Smoother Remodel
We recommend planning every step before demolition starts. That means confirming pipe sizing, vent locations, and access points. If you're installing a new sink or faucet, check that you have shutoff valves on both hot and cold supplies. Consider upgrading older shutoffs or adding hammer arrestors to prevent water hammer when the new faucet closes quickly. If you're adding a garbage disposal, make sure the electrical and plumbing rough-ins match its requirements, some older homes need a new circuit or outlet near the sink. We regularly provide faucet and fixture installation and garbage disposal services during kitchen remodels.
Don't overlook the supply piping. If you bump into sections of deteriorated galvanized or leaking copper, a partial update may be the smart choice now rather than patching later. We handle pipe repair and repiping so your new kitchen won't be held back by unreliable older lines.
Signs You Need a Pro Instead of DIY
- The new sink location is more than a few feet from the old one.
- You see corrosion, rust, or white mineral buildup on pipes.
- Drain lines are cast iron or have visible pitting and scale.
- Drains or supply lines run through finished basements or concrete slabs.
- You're unsure about vent pipe location or code requirements.
- There's evidence of past leaks or water damage under the old sink.
