MaintenanceUpdated June 23, 2026
Kitchens in Glendale Heights see a lot of use, especially in homes built between the 1960s and 1980s. For households that cook often or entertain, a pot filler or a second sink can make a big difference. We've worked with the kinds of plumbing systems common in this area, so we know where the challenges tend to come up. Hard Lake Michigan water, original galvanized lines, and tight cabinet spaces all play a role in planning a reliable installation.
Why These Upgrades Matter in Older Kitchens
Many kitchens in the western suburbs were designed before modern cooking habits took hold or before bigger appliances became standard. Adding a pot filler means you don't have to haul heavy pots from the sink to the stove. A second sink helps separate prep and cleanup, especially if more than one person uses the kitchen at a time. But your home's plumbing age and layout both affect what's possible without expensive surprises down the line.
Typical Plumbing Hurdles for Pot Fillers and Extra Sinks
Houses in Glendale Heights often have original supply lines hidden behind thick drywall or above finished basements. If your supply lines are galvanized or show signs of rust, we usually recommend a pipe repair or repiping discussion before adding a new fixture. Another common snag is low water pressure at the kitchen. This can mean undersized pipes or sediment buildup from years of hard water use. We see this a lot in older tract homes that haven't had recent plumbing updates.
Planning for Pot Fillers
Installing a pot filler isn't just about running a cold water line. The valve must be installed above the stove at a safe height, and the supply should be shut off when not in use. We inspect for accessible shutoff valves and recommend high-quality fittings to handle the thermal expansion that comes from running hot or cold water next to a cooking surface. Drilling into kitchen walls that back up to brick or tile can reveal all sorts of surprises, so we map out the route carefully before doing any cutting.
Adding a Second Sink
Remodels that include an island, prep zone, or bar area often call for a second sink. For this, drainage and venting must be properly sized, especially if your home's kitchen stack or main drain shows signs of age. We sometimes find cast iron drain lines under slab floors or in crawl spaces, which can complicate tying in a new fixture. Homes with clay-rich soil, like much of Glendale Heights, need careful grading and installation around the drains to avoid slow drainage.
We always confirm if your current venting is adequate, since poor venting can mean slow drains or gurgling sounds. Some island sink installs require an air admittance valve (AAV) if tie-ins to the vent stack aren't possible. We can explain those tradeoffs and what's allowed under local code.
Practical Steps Before Upgrading
- Check for existing galvanized or corroded copper supply lines near the planned fixture location.
- Measure cabinet and wall space for safe clearances and accessibility for future repairs.
- Test current water pressure at the kitchen. Weak flow suggests clogged aerators or more serious pipe restrictions.
- Review the main shutoff location and condition in case any work requires turning off the whole house.
- Plan for fixture shutoffs (quarter-turn valves) to isolate new additions in an emergency.
- Confirm drainage slope and venting, especially if the home has had previous remodels or basement work.
Maintenance After Installation
Once your pot filler or second sink is in place, regular checks make sure things stay trouble-free. Keep an eye out for slow drainage, dripping supply lines, loose shutoff valves, or any water staining under cabinets. Hard water can also build up in aerators and at the fixture joints, so cleaning those out should be part of your regular kitchen routine.
If you notice slow drains or smells coming from your new sink, a professional drain cleaning may be needed. Any sign of leaking at new connections should be handled fast to avoid damage to walls or cabinetry. For kitchens that share a wall with a bathroom, it's important to make sure the additional water use doesn't overload older drain stacks, something our leak detection and repair team can check as part of a visit.
