Even a small drip from a faucet in your Libertyville home adds up. It wastes water, stains sinks, and signals that something in your plumbing needs attention. We see this issue all the time in homes around here, especially in older housing where original fixtures or supply lines have been in use for decades. Hard water from Lake Michigan doesn't help, and neither does the corrosion common in older galvanized piping. If you've tried tightening the handle or swapping a washer but the faucet still drips, it's time to take a closer look at the real cause and your best solution.
Why Faucets Start Dripping
Most faucet leaks come down to worn or damaged internal parts. In homes built before the 1970s, it's common to run into original compression-style faucets with rubber washers. Over time, those washers get hard or misshapen, which keeps the valve from sealing. Newer cartridges and ceramic disk faucets have different weak points, but even these can fail if rubber seals or O-rings wear out or mineral buildup interferes with the seal.
Here in Libertyville, municipal water is moderately hard. That means minerals like calcium and magnesium build up inside fixtures and around valves. This can chew up seals and gaskets faster than in softer water areas. That same mineral buildup often makes tight connections loosen up and can even split brittle old parts inside the body of the faucet.
Common Signs You Need Replacement, Not Just Repair
Some drips are an easy fix. Others stick around no matter what, or come back right away. We often see these warning signs in local homes:
- The drip doesn't stop after tightening or replacing the washer or O-ring.
- Corrosion around the base or rust stains under the faucet.
- Handles wobble, feel loose, or don't turn smoothly.
- Water leaks from around the stem or under the sink, not just the spout.
- Visible cracks in the body, or the finish is peeling after years of cleaning products and hard water.
- Parts are obsolete, hard to find, or the fixture is outdated.
If you spot one or more of these, a replacement is usually going to be faster, safer, and less trouble in the long run than piecing together multiple repairs.
Steps We Take to Fix a Persistent Drip
Our crew always starts by shutting off the water supply before working on any fixture. In Libertyville, main shutoff valves are often in the basement or crawl space, and older homes can have stubborn, corroded valves that stick. Once the water is off, we'll inspect the faucet body, seats, and stem. If it's a simple washer or cartridge job and the rest of the faucet is in good shape, we'll handle the repair. For signs of deeper corrosion, cracked components, or a heavily mineralized fixture, we recommend a full replacement.
Installing a new faucet requires a few practical steps:
- Disconnect hot and cold supply lines under the sink, checking for leaks or signs of wear.
- Remove the old faucet and clean mineral deposits off the sink deck to ensure a tight seal.
- Inspect supply valves for leaks or corrosion. If needed, we can include pipe repair or repiping and replace old galvanized or corroded lines while the faucet is out.
- Install the new fixture, making sure connections are tight and sealed. If the new faucet comes with new hoses, we always use those instead of reusing old lines.
- Check for leaks, adjust water flow, and make sure the aerator is clear for proper pressure.
It's good practice to check the entire area for leaks after installation, especially with Libertyville's older clay soil and water table concerns. Undetected drips can lead to bigger problems under cabinets or even contribute to basement moisture issues if not caught right away.
Special Issues in Libertyville Homes
The mix of historic and modern housing in Libertyville brings some unique plumbing quirks. Many older properties still use original galvanized supply lines, which corrode and trap mineral scale. Even newer homes can see more rapid faucet wear due to moderately hard water and the freeze-thaw cycles common in our region. In winter, pipes under exterior walls can get cold enough to sweat, which adds to corrosion around supply shutoffs and fittings.
If you notice widespread rust on fittings or if your water pressure seems lower than usual, this can point to buildup or failing pipes. In those cases, faucet replacement is an excellent time to consider broader repiping or even a water heater service if hard water has caused sediment problems throughout your system. Sediment buildup in the heater can speed up faucet damage, so keeping an eye on both makes sense.
When to Call a Licensed Plumber
Some Libertyville homeowners enjoy tackling small repairs themselves, and for those with modern fixtures, a cartridge or washer replacement can work well. But if you run into stubborn corrosion, stripped threads, or leaks under the sink that you can't trace, it's best to have a licensed plumber step in. Trying to force stuck valves or overtighten supply lines can crack fittings or even cause leaks behind the wall, which lead to much bigger issues down the road.
If you're replacing a faucet and find that your supply shutoff won't budge, or if the drip is just one of several signs of aging plumbing, we can handle a full faucet and fixture installation safely. We also provide drain cleaning if slow drains are part of the problem, and offer sump pump services for homes affected by the water table and clay soils in the area.
