The Basics That Actually Prevent Big Repairs

Most plumbing advice focuses on what to do once something's already gone wrong. This is the other half: the background knowledge that helps you catch problems before they become repairs, especially in a county with a wide mix of municipal, well, and septic systems, older housing stock, and flood-zone construction rules.

Know Your Water Pressure

Municipal water pressure that runs too high, generally above 80 psi, puts ongoing stress on supply lines, fittings, and appliance valves, and is a common reason for premature failures in toilets, washing machines, and water heaters. A simple pressure gauge that threads onto an outdoor spigot will tell you where your home stands in a couple of minutes. If pressure runs high, a pressure-reducing valve (PRV) installed where the main line enters the house brings it down to a safer range and protects everything downstream of it.

Septic Systems: Different Rules Apply

If your property isn't on municipal sewer, what you put down the drain matters even more than usual. A septic system relies on bacteria to break down waste, and that bacterial balance can be disrupted by excessive bleach, antibacterial soaps in large quantities, and harsh chemical drain cleaners. Garbage disposals also send more solid material into a septic tank than it's typically sized for, which can shorten the interval between pump-outs. If you don't already know when your tank was last pumped, that's worth finding out before it becomes obvious the hard way.

Know What Your Supply Lines Are Made Of

Homes built or re-plumbed at different points in the past 60 years may have galvanized steel, polybutylene, copper, or PEX supply lines, and it matters which one you have. Galvanized pipe corrodes from the inside out and gradually restricts flow long before it leaks. Polybutylene, common from the late 1970s through the 1990s, has a well-documented history of fitting failures and is generally considered due for replacement regardless of current condition. If you don't know what's behind your walls, a plumber can usually identify it quickly by checking an accessible section in a basement or crawl space.

Flood Zone Considerations

A large share of Cape May County sits in a FEMA-designated flood zone, which affects more than just insurance. Backflow preventers on certain fixtures, check valves on low-elevation drains, and specific requirements for mechanical equipment elevation can all apply depending on the property's flood zone designation and any renovation history. This is worth confirming with a licensed plumber and your local building department before any major plumbing work, not after it's already installed incorrectly.

What Should Never Go Down a Drain or Toilet

• Cooking grease and oil, even small amounts repeated over time.
• "Flushable" wipes, which frequently don't break down and are a leading cause of both home and municipal sewer clogs.
• Coffee grounds and eggshells, which don't liquefy and settle in low points of the line.
• Medications, which belong at a pharmacy take-back location, not the toilet.
• Paint, solvents, or any chemical not specifically labeled safe for septic or sewer disposal.

A Short List Worth Doing This Month

• Test your home's water pressure and install a PRV if it's running high.
• Find out when your septic tank was last pumped, if you have one.
• Locate your main shutoff and confirm it actually turns.
• Have a plumber identify your supply line material if you don't already know it.

Most of the plumbing problems we see weren't unpredictable. The information was just sitting unused until something failed.
