InstallationUpdated July 7, 2026
Kitchens in Gilberts homes, whether built just a few years ago or going back to the late 20th century, depend on careful plumbing rough-ins when it's time for a remodel. If the supply lines and drains are set up wrong, everything that follows is a headache, leaks behind the wall, low pressure, slow drains, or code violations that stall the job. Our team has worked through enough remodels to know how these jobs can go off track if the plumbing isn't right from the start.
Why Getting the Rough-In Right Matters
The rough-in is the backbone of your new kitchen. This is when we route new copper or PEX water lines, install shutoff valves, and set the drain and vent pipes for sinks, dishwashers, and refrigerators. Gilberts homes mostly use municipal water from the Fox River, so the supply is reliable, but the builder-grade piping in some older developments isn't always up to current standards. A rushed or DIY rough-in can leave you with pinhole leaks or noisy water hammer problems once everything's covered by drywall and cabinets.
Planning for Code and Function in Gilberts
Kane County and the village require permits for kitchen remodels, and the inspectors here expect proper sizing for both supply and drain lines. For most kitchens, we use 1/2-inch lines for supplies and a 2-inch PVC or ABS drain for the main sink. Venting is critical, without a proper vent stack or AAV, you risk slow drainage and sewer smells. In the humid continental climate here, winter freeze/thaw means exterior wall pipes must be insulated or kept inside conditioned space. If you're moving the sink or adding an island, we often need to break up concrete or reroute lines through joists and walls, which takes careful planning.
What to Expect During a Kitchen Rough-In
- Shutdown of main water supply and labeling of existing lines
- Cutting, capping, or rerouting old galvanized, copper, or PEX lines as needed
- Placement of new hot and cold supply lines, always with individual shutoff valves for each fixture
- Drilling and running new drain lines to align with the new sink, dishwasher, or refrigerator location
- Installing vent piping to code (usually through the roof or tying into an existing stack)
- Pressure testing all lines for leaks before finishing the walls
We sometimes find that a remodel is the right moment for updated pipe repairs or repiping if the existing lines are corroded or undersized. For new fixtures, our crew handles all the faucet and fixture installations as part of the finishing stage.
Common Issues With Older and Newer Kitchen Plumbing
Rapid suburban growth means Gilberts has a mix of older and newer plumbing systems. In kitchens from earlier developments, galvanized supply lines are sometimes found, and those are prone to rust and buildup that reduce flow. Newer homes often use PEX or copper but can suffer from amateur rough-ins, lines run too close to exterior walls or without proper supports. Both situations risk leaks, freezing, and slow drains. We also see issues with improperly installed dishwasher drains, missing air gaps, or vent lines that aren't tied in according to code.
Flooding isn't common in most kitchens, but because of the Fox River's proximity and higher water tables in this area, some homeowners include extra measures like check valves or tie their kitchen plumbing into a system with a sump pump, especially for ground-level or basement kitchens.
Gas Lines, Appliances, and Water Heaters
If you're adding a gas range or relocating an oven, a safe, code-compliant gas line installation is part of the rough-in process. For remodels that include a tankless or larger water heater, our water heater services keep everything up to the local requirements for venting and supply. As kitchens get more high-efficiency fixtures, the demand on your main line may go up, so we sometimes check for PRV (pressure reducing valves) or install new shutoff valves to make future service easier.
Warning Signs and When to Update Existing Plumbing
- Low water pressure at the kitchen faucet or dishwasher
- Unusual hammering sounds when turning taps on or off
- Visible corrosion on exposed pipes under the sink
- Slow draining or frequent clogs in the kitchen sink
- Water stains or damp spots along walls or in the cabinet base
If you notice any of these, it's best to schedule leak detection and repair before walls and cabinets go back in. This can prevent much bigger headaches after the remodel is complete.
