InstallationUpdated June 19, 2026
Many Warrenville homes built from the 1960s through the 1990s were designed around basic kitchen layouts. When it's time to remodel, homeowners often ask us about adding a pot filler above the stove or a second prep sink for convenience. Both upgrades add function but require careful planning and skilled plumbing work, especially with older pipe materials or tight kitchen spaces found in many local houses.
Why Warrenville Kitchens Need Careful Plumbing Upgrades
The typical supply lines running through ranch and two-story homes in Warrenville include copper, but some still have stretches of old galvanized steel, especially near shutoffs and branch lines. Before we cut into existing pipes, we check for corrosion and mineral buildup from the moderately hard municipal water. This prevents future leaks and ensures any new fixture, like a pot filler or secondary sink, gets a reliable water source without constant flow issues or repairs down the road.
Pot Fillers Above the Stove
A pot filler adds a cold water line above the cooking range, letting you fill large pots right at the stove. It's a job that sounds simple but often involves running a dedicated supply behind finished walls or through cabinetry, depending on your kitchen's layout and access. For homes with finished basements, we sometimes trace the supply line through floor joists, always keeping an eye out for older galvanized or even lead branches that should be replaced with copper or PEX to meet modern codes.
We always install a separate shutoff for the pot filler, as well as a dedicated valve at the wall, so you can isolate the line if there's ever a leak. If we run into any rusted or corroded pipe, we'll recommend repiping that section so you're not risking a kitchen leak over a convenience upgrade.
Adding a Second Sink
Second sinks, often called prep sinks, give you a handy spot for rinsing veggies or entertaining, and they're common requests during kitchen remodels in split-level and open-plan homes around DuPage County. These sinks need both water supply and a proper drainage connection. The challenge comes when original kitchen drains are undersized or run in tricky directions due to the age and design of local homes. We've seen older kitchen drains made of cast iron, which can have rough interiors or partial clogs from decades of use.
Our team will inspect where the new sink will go and map the best route for supply lines and drain pipes. If your home has clay-tile sewer lines or older galvanized drain branches, we may suggest replacing sections to prevent tree-root intrusion or future blockages. For drainage, every new sink needs a vented P-trap, and all connections are tested for leaks before the job is finished. If your main line needs cleaning or has root buildup, we also offer drain cleaning to keep everything running smoothly.
- Check if your existing supply lines are copper or galvanized
- Inspect for mineral buildup or corrosion
- Plan access to branch off existing lines (sometimes through cabinets or walls)
- Install dedicated shutoffs for all new fixtures
- Test for leaks and proper drainage before finishing walls or cabinetry
Important Plumbing Details for Local Homes
With Warrenville's humid continental climate, pipes near exterior walls are at risk in winter, so we always insulate new supply lines added during kitchen remodels. The moderate water hardness here can clog aerators or pot filler valves over time. We recommend annual maintenance for any new fixtures.
Some homes in the area still have clay-tile main sewers. If we're adding a sink farther from the original drain stack, we always check for slope and proper venting, and we can scope your lines as part of sewer line services if there's any concern about backups.
Integrating Faucets, Fixtures, and Appliances
Whether you want a commercial-style pot filler or a bar-style prep sink, we handle faucet and fixture installation with careful attention to pressure, flow, and mounting. We also check that your shutoffs and supply hoses are up to current code, replacing old-style saddle valves or brittle hoses as needed. If your remodel includes a new dishwasher or garbage disposal, our garbage disposal services get everything connected the right way the first time.
Should You Plan for Repiping?
A kitchen remodel is a good opportunity for some homeowners to address upgrades beyond the visible fixtures. If you've experienced leaks, discolored water, or low pressure, it might be time to talk about full pipe repair and repiping for those old galvanized or corroded copper lines. Our crew is used to working in tight utility spaces and can coordinate with other remodel trades to avoid disruption. We always focus on long-term solutions that match the demands of Warrenville's seasonal climate and municipal water quality.
