Low water pressure at the kitchen faucet, shower that barely rinses, or a washing machine that takes too long to fill are common complaints in Burbank homes. Many of these issues start with an undersized or aging water service line, especially in older houses built during the city's mid-20th century growth. Upgrading the main water line isn't just about convenience, it protects pipes and appliances, supports updates like new bathrooms, and keeps everything running as it should.
Why Older Burbank Homes Still Have Small Water Lines
Much of the single-family housing in Burbank dates back to the postwar building boom, when 1/2-inch or 5/8-inch galvanized service lines were common. Back then, demands were lower, one bathroom, smaller water heaters, and fewer appliances. Now, with bigger kitchens, more bathrooms, and additions, these old lines can't keep up. Hard water from Lake Michigan can add scale buildup inside pipes, making pressure drops worse over time.
Common Warning Signs of an Undersized Water Service
- Low water pressure throughout the house, especially when more than one tap is in use
- Inconsistent temperature or flow when running hot and cold at the same time
- Fill times for toilets, tubs, or washing machines are slow
- Older visible piping near your shutoff is galvanized or corroded copper
- Plans to add a bathroom or expand plumbing needs
Heavy clay soils in Burbank also put extra stress on buried pipes. Freeze-thaw cycles every winter can crack or pinch old lines, making pressure issues even worse. If your home still has the original service, it's worth checking whether an upgrade is overdue.
How We Troubleshoot and Pinpoint Water Line Issues
Our team starts by measuring pressure at key points: main shutoff, hose bibs, and fixtures farthest from the service entry. We look for bottlenecks and compare readings against what's typical for Burbank's municipal supply. If there's serious rust or buildup on the exposed piping, we often recommend a full inspection. We also check for shutoff valves that are stuck or failing, and can use specialized tools to listen for leaks or see if the line is partially collapsed or blocked by scale.
Troubleshooting sometimes traces pressure problems to old fixtures or branch lines inside the house. In that case, a targeted repiping project might do the trick. But when the main water service is too small, updating the supply line from the street is the only real fix.
What Upgrading a Water Service Line Involves
Replacing an old or undersized water line isn't a quick patch job. We work with homes across Burbank's clay-heavy soil, using the right methods for trenching and backfill to protect both plumbing and foundations. The new line, usually copper or high-density polyethylene (HDPE), is sized based on fixture count and building code, most homes benefit from a 1-inch main line. We install new shutoff valves at both ends, pressure test the new pipe, and verify there are no leaks.
Heavy rains and high water tables in this part of Cook County mean sump pumps sometimes run hard during installation. We coordinate with any sump pump or drainage concerns to avoid water intrusion during the project. If we find corroded pipes inside the house, a full inspection helps plan any needed pipe repairs or repiping at the same time.
Making Sure Your Home Keeps Up With Modern Demands
With more families adding bathrooms, luxe showers, and high-efficiency appliances, adequate water flow matters more than ever. An upsized service line protects your investment in water heaters and fixtures, and prevents strain on older plumbing. We always check for proper pressure-reducing valves (PRVs) if needed, and consult on upgrades to kitchen or bath plumbing. When upgrades are planned, it's a good time to review the whole system, not just the supply, but also drain, vent, and shutoff setups. If you're also noticing slow drains or recurring clogs, our drain cleaning team can check for issues while access is open.
Practical Steps Burbank Homeowners Can Take
- Check exposed water lines near your main shutoff for corrosion, rust, or signs of old galvanized pipe
- Test pressure at several fixtures with multiple taps running
- Review plumbing plans for remodels, especially if adding bathrooms or laundry rooms
- Contact a licensed plumber for an inspection if you notice low flow or suspect an aging water line
- Ask about leak detection with modern equipment, especially if water bills rise without explanation
Sometimes, a simple leak detection and repair can make a difference. But for many homes around Cicero Avenue, Harlem Avenue, or 95th Street, full water service upgrades are the long-term answer to low pressure and pipe headaches.
