Spring Plumbing Maintenance Guide — Annual Checkup for Your Home

Walk through the basement, crawlspace, and any area with exposed plumbing. Look for: new green/white corrosion on copper fittings (developing pinhole leaks), water stains or mineral deposits below pipe joints, damp insulation on pipes (indicating a slow leak underneath), and any pipe that appears bowed, bulged, or has a visible crack (frost damage that hasn't started leaking yet). A hairline crack from a winter freeze may drip only when water pressure is high — check during morning peak usage.

Connect a pressure gauge ($10–$15 at hardware stores) to a hose bib or laundry faucet. Normal residential pressure is 40–60 PSI. Below 40: possible supply restriction, failing pressure regulator, or municipal supply issue — contact your water utility. Above 80: excessive pressure that stresses pipes, fittings, and appliances — you need a pressure reducing valve (PRV) or your existing one needs service. Pressure regulators (PRVs) wear out every 7–12 years; sudden pressure changes in spring suggest the regulator failed during winter.

Annual water heater flushing removes sediment that reduces efficiency and shortens tank life. Connect a hose to the drain valve, open it, and flush until water runs clear. While draining, inspect the output: rust-colored water indicates internal corrosion; sandy sediment is normal mineral buildup. If the tank is 5+ years old, check the anode rod (the sacrificial metal rod that prevents tank corrosion): unscrew the hex head on top of the tank and pull the rod. If it's more than 50% depleted (less than ½ inch diameter), replace it ($20–$50 for the rod). A depleted anode means the tank itself is corroding.

Gently rock each toilet — any movement means the wax ring seal is compromised (sewer gas and water leak at the base). Listen for hissing (running fill valve) or periodic refilling (flapper leak). Add food coloring to the tank; if color appears in the bowl within 15 minutes, the flapper is leaking (200+ gallons/day wasted). Check the supply line connection at the wall and the tank for moisture. A running toilet discovered in spring may have been wasting water all winter — your next bill will confirm.

Before turning interior shutoff valves back on for outdoor faucets, close the outdoor faucet (which should have been left open all winter). Then slowly open the interior shutoff valve while someone watches the outdoor faucet and the pipe inside the wall (if accessible). If water sprays from a crack or joint, or leaks inside the wall, shut off immediately — the pipe has frost damage and needs repair. Pressurize one faucet at a time so you can identify which line is damaged if a leak occurs.

Turn on the irrigation supply valve slowly and pressurize the system. Run each zone individually for 3–5 minutes while walking the coverage area. Check for: broken sprinkler heads (frost heave or mower damage), misaligned heads, geysers from cracked fittings, low-pressure zones (indicating a line break), and valve boxes with standing water (leaking valve). Note any issues by zone number. Most spring irrigation repairs are simple head replacements ($5–$15 each) or fitting repairs.

If you shut down outdoor kitchen, bar, or entertainment plumbing for winter, reverse the shutdown process: close outdoor faucets, slowly open interior supply valves, check for leaks at all connections, and run water through all fixtures until it flows clear. Reconnect ice maker lines, misting systems, and any outdoor appliances. Check P-traps under outdoor sinks — if RV antifreeze was added for winter, run water through until the antifreeze is flushed and clear water fills the trap.

Winter's cold water temperatures allow grease to accumulate faster in drain lines. Run very hot water through every drain for 2–3 minutes, then apply enzymatic drain cleaner to the kitchen sink, bathroom sinks, and shower drains. Let the enzymatic cleaner work overnight (bacteria cultures need 6–8 hours). This dissolves winter accumulation and restores full flow before summer's higher usage demands. Never use chemical drain cleaners — they damage pipes and kill beneficial bacteria in septic systems.

Remove and clean every drain strainer, pop-up stopper, and tub overflow cover plate in the house. Hair and soap accumulate on these components all winter. While the pop-ups are out, use a flexible drain cleaning tool ($5 — a plastic barbed strip) to pull hair from the first 12 inches of the drain pipe. Also clean bathroom sink overflow openings (the small hole near the top of the basin) — they harbor bacteria and cause persistent drain odors. A clean start in spring prevents summer clog emergencies.

Spring is the ideal time for sewer line service: roots are just beginning active growth (cut them now before they expand), the ground is soft for cleanout access, and plumber availability is better than summer peak season. A camera inspection ($200–$400) reveals root intrusion, pipe condition, and developing problems. If roots are present, mechanical cutting ($200–$500) clears them and annual cutting keeps the line clear. Homes with mature trees should have sewer line service every 1–2 years as preventive maintenance.
