Adding a Pot Filler or Second Sink to Your Glendale Heights Kitchen

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.

Frequently Asked Questions

In older Glendale Heights homes, pot filler installations sometimes reveal original galvanized lines or undersized copper. We evaluate your existing supply lines and recommend any upgrades if water flow or reliability would be affected. Sometimes a small reroute or new shutoff is all that's needed.

Adding a second sink means your drain and vent system needs to handle extra water. If your drain lines are cast iron or have older connections, an inspection can prevent slow drainage or potential backups. We check venting and slope during the planning stage to avoid future issues.

Pot fillers should be shut off at the handle after each use. Occasionally check for drips at the joints and clean any hard water buildup from the aerator. If you spot corrosion or a persistent drip, have it checked. Regular use and gentle operation help keep the fixture working longer.

Low pressure often points to clogged aerators, sediment in the lines, or pipe corrosion. We can help pinpoint the cause. Sometimes flushing the lines or cleaning the aerator solves it, but older homes might require a section of pipe to be replaced for full flow.
