☑ Complete Checklist
Preventive Drain Maintenance
- ☐Pour one gallon of boiling water down each drain weekly to dissolve grease and soap scum.
- ☐Use a hair strainer in all shower and tub drains; clean it after every shower.
- ☐Never pour cooking oil, coffee grounds, or eggshells down the kitchen sink.
- ☐Flush each drain monthly with ½ cup baking soda followed by ½ cup white vinegar, then hot water after 15 minutes.
- ☐Run hot water for 30 seconds after each use of the garbage disposal to flush debris through the P‑trap.
- ☐Avoid using chemical drain cleaners; they damage PVC pipes and can weaken copper joints over time.
Warning Signs You Shouldn’t Ignore
- ☐Listen for gurgling sounds from toilets or sinks when water drains elsewhere — it may indicate a blocked vent or main sewer line.
- ☐Check for slow drainage in multiple fixtures (e.g., tub and sink) simultaneously; that often means a clog in the main line rather than a local one.
- ☐Notice foul odors from drains? A dry P‑trap or sewer gas leak could be present — pour water into seldom‑used drains to reseal the trap.
- ☐Look for standing water around floor drains, especially after heavy rain; this could signal a cracked sewer line or bellied pipe.
- ☐Monitor your water meter for unexplained usage when no fixtures are running — a hidden slab leak may be wasting water and damaging your foundation.
Water Heater Care (Gas & Electric)
- ☐Flush the water heater tank annually by attaching a garden hose to the drain valve and running until the water runs clear (removes sediment).
- ☐Test the temperature/pressure relief (TPR) valve every six months: lift the lever briefly to make sure water flows, then let it snap back.
- ☐Set the thermostat to 120°F — hot enough for cleaning, cool enough to prevent scalding and slow mineral buildup.
- ☐Inspect the anode rod every two years; if it’s less than ½ inch thick or covered in calcium, replace it to prevent tank corrosion.
- ☐For gas heaters, check the vent pipe for blockages or rust; a blocked vent can cause carbon monoxide backup into your home.
- ☐Listen for popping or rumbling sounds from the tank — that’s sediment boiling; it reduces efficiency and shortens the unit’s lifespan.
Sewer Line Awareness
- ☐Know where your cleanout cap is (usually a white or black plastic pipe sticking out of the ground near the house). Keep it accessible and not buried under mulch.
- ☐Avoid planting trees or shrubs with aggressive root systems (willow, poplar, maple) within 10 feet of the sewer line.
- ☐Never flush “flushable” wipes, feminine products, or paper towels — they do not break down and cause massive sewer line clogs.
- ☐Schedule a video camera inspection every 2–3 years if your home has older clay or cast‑iron pipes, which are prone to cracks and root intrusion.
- ☐If you notice sewage backup in a lower‑level fixture after heavy rain, your lateral line may be cracked or a root mass is blocking flow — call a pro immediately.
Fixture & Pipe Inspections
- ☐Check all exposed pipes under sinks for signs of corrosion, white calcium buildup, or dampness — early indicators of a slow leak.
- ☐Test kitchen and bathroom faucets for proper flow; reduced flow often means clogged aerators or hard‑water scale inside the cartridge.
- ☐Examine toilet supply lines and shut‑off valves for rust or bulges — replace braided steel lines every 5 years to prevent bursts.
- ☐Verify that outside hose bibs have a vacuum breaker (anti‑siphon device) installed to prevent backflow of contaminated water into the house.
- ☐Feel your water pressure using a gauge on a hose bib; ideal range is 40–60 psi. Above 80 psi puts strain on joints and appliances — consider a pressure‑reducing valve.
💡 Pro Tips from the Experts
💡 The Baking Soda Trick Works – But Only If You Wait
After adding baking soda and vinegar to a drain, let the fizz sit for a full 15 minutes before flushing with hot water; rushing it flushes away the acid before it breaks down organic debris.
💡 Garbage Disposal Myth: Cold Water Only? Not Always.
Run cold water when grinding food waste to keep grease solid and avoid clogs, but after you turn off the disposal, switch to hot water for 30 seconds to push the waste past the P‑trap and into the main line.
💡 Know Your Pipe Material – It Affects How You Maintain
Homes built before 1960 often have galvanized steel or cast‑iron drains that are prone to rust buildup; avoid drain snakes with sharp tips and consider professional hydro‑jetting instead.
💡 A Leaking TPR Valve Is Not ‘Normal’ – Replace It
If water dribbles from the temperature/pressure relief valve when the heater isn’t overheating, the valve has failed; replace it immediately to prevent a catastrophic tank rupture.
💡 Your Free Drain Inspection – What We’ll Do
When you book any service call with PlumberPro Services, our technician will perform a visual drain check, run a handheld camera scope on the main kitchen or bath drain, and provide a written report — all at no extra cost.
💡 Portland‑Specific: Watch for Tree Roots in Early Spring
Our wet spring conditions accelerate root growth; if you notice slow drains in March or April, call us for a camera inspection before roots crack your clay pipes entirely.
