Catch issues before they escalate
Save money on repairs and water bills
Extend the life of pipes, fixtures, and water appliances
Maintain safe, clean water for your family
Ensure peace of mind year-round

Use this detailed checklist to stay on top of your plumbing maintenance in Kent, WA.

Inspect for Visible Leaks

Check under sinks, behind toilets, and around water-using appliances. Look for dampness, puddles, or discoloration. Small leaks can grow into large damage quickly.

Test All Faucets and Showerheads

Turn on all faucets and showerheads in your home. Check for good pressure, even spray, and any dripping after turning them off. Clean or replace aerators if needed.

Inspect Water Heater Performance

Ensure it’s producing consistent hot water. Check for sediment buildup, corrosion on fittings, or leaks near the base. Flush it yearly for optimal performance.

Inspect Water Heater Pressure Relief Valve

Lift the TPR valve to ensure it opens and reseals properly. This is a key safety feature that prevents pressure buildup.

Flush Your Water Heater Tank

Drain and flush the water heater to remove sediment and debris. This helps prevent corrosion and keeps the unit running efficiently.

Check Water Pressure in Your Home

Use a pressure gauge to test pressure levels. Ideal range is 40–60 PSI. High pressure can damage appliances and pipes. Install or adjust a pressure regulator if needed.

Inspect Exposed Pipes for Corrosion or Damage

Walk through your basement, garage, or crawl space to inspect visible pipes. Look for rust, bulges, discoloration, or condensation that may signal trouble.

Examine Hose Bibs and Outdoor Faucets

Turn them on and check for leaks or drips. Make sure frost-proof spigots are functioning and that there’s no water leaking behind the wall.

Insulate Exposed Pipes Before Winter

Wrap pipes in unheated areas like attics, garages, and crawl spaces to prevent freezing. Use foam sleeves or insulation tape for added protection.

Check Drain Flow in All Sinks, Tubs, and Showers

Slow drains could be a sign of buildup or early-stage blockages. Use a natural drain cleaner or call CPR Rooter if persistent.

Clean Faucet Aerators and Showerheads

Remove aerators and showerheads and soak them in vinegar to remove mineral deposits. This helps restore pressure and improves water efficiency.

Inspect Washing Machine Hoses

Check water supply and drain lines for signs of wear or leaks. Even small drips can damage cabinets and flooring over time.

Inspect Dishwasher and Refrigerator Lines

Check water supply and drain lines for signs of wear or leaks. Even small drips can damage cabinets and flooring over time.

Evaluate Water Quality

Look for signs of hard water (white residue on fixtures), odd smells, or discoloration. Consider water testing or filtration solutions if needed.

Locate and Test Your Main Shut-Off Valve

Make sure you know where it is and that it turns easily. In an emergency, quick shut-off can prevent major flooding.

Clean and Check Sump Pump (If You Have One)

Ensure the sump pump works properly and clean out any debris in the pit. Test it by pouring water into the pit and watching the pump cycle.

Inspect Garbage Disposal

Run the unit and check for strange noises or vibrations. Clean it regularly and avoid putting fibrous or greasy waste down the drain.

Schedule a Whole-Home Plumbing Inspection

Have CPR Rooter do a full system inspection to catch any hidden or complex issues — especially before winter or after heavy rainfall seasons.

Maintain Plumbing Fixtures

Check seals, handles, mounting brackets, and gaskets on all your fixtures. Loose or deteriorated components can lead to leaks or water damage.

Listen for Unusual Pipe Noises

Banging, whistling, or knocking can indicate water hammer or pressure issues. Don’t ignore these sounds — they often point to deeper problems.

Review Your Plumbing Emergency Plan

Ensure everyone in your home knows what to do in case of a major leak or burst pipe. Post instructions near the shut-off valve.

Clear Rain Gutters and Downspouts

Ensure proper exterior drainage. Blocked gutters can lead to water pooling near your foundation, which can affect basement and crawl space plumbing.

Upgrade Old Plumbing Where Needed

If your home still has galvanized steel or aging copper pipes, it may be time for an upgrade. Newer materials like PEX offer better performance and longevity.
