Your Go-To Plumbing Inspection Checklist
The Ultimate Plumbing Inspection Checklist for 2025 isn’t just for cautious homeowners—it’s for every homeowner. Why? Because plumbing problems rarely knock before barging in with water damage, skyrocketing bills, or unpleasant surprises.
If you’re in Southeast Texas, regular plumbing inspections are crucial for keeping your system efficient, leak-free, and long-lasting. That’s why 409 Group created this updated, comprehensive checklist to help you stay ahead of plumbing disasters.
Our Comprehensive Plumbing Solutions include annual inspection services, but if you’re more of a DIY-first type, this guide covers what to check, how often, and what’s worth calling in the pros for.
Why Annual Plumbing Inspections Matter
A yearly plumbing inspection can:
- Prevent unexpected (and costly) emergencies
- Extend the life of your plumbing system
- Improve home safety and water quality
- Identify hidden leaks that drive up your water bill
- Protect your home’s value
A simple inspection today can save you thousands tomorrow.
What’s Included in a Proper Plumbing Inspection?
A thorough inspection covers every visible and accessible part of your plumbing system, from your water main to your drains. Here’s the full checklist for 2025:
1. Water Heater Check
- Look for rust, corrosion, or leaks
- Confirm the pressure relief valve is functional
- Drain and flush the tank to remove sediment (if applicable)
- Test temperature settings (120°F is ideal)
2. Toilet Function & Seal
- Check for leaks at the base
- Test flushing power and tank fill speed
- Inspect flappers and fill valves for wear
- Listen for phantom flushes (a sign of internal leaks)
3. Faucet and Showerhead Inspection
- Look for drips, leaks, and corrosion
- Test water pressure and flow consistency
- Clean or replace clogged aerators
- Check underneath sinks for signs of moisture or mold
4. Drain Performance
- Fill sinks and tubs to test draining speed
- Listen for gurgling sounds (a sign of venting or blockage issues)
- Use natural cleaners (baking soda and vinegar) monthly
- Avoid using chemical drain openers
5. Garbage Disposal Check
- Run with cold water and check noise levels
- Look for leaks under the sink
- Avoid using fibrous or starchy food scraps
6. Washing Machine Hoses
- Inspect hoses for bulges, cracks, or leaks
- Ensure connections are secure
- Consider upgrading to braided stainless steel hoses for durability
7. Dishwasher & Refrigerator Water Lines
- Check for leaks or puddling behind the appliances
- Ensure connections are tight and free of corrosion
8. Water Pressure Test
- Use a pressure gauge at an outdoor spigot
- Ideal pressure: 40–60 psi
- High pressure (>70 psi) can strain your pipes and appliances
9. Water Meter Check (for leaks)
- Turn off all water inside the house
- Watch the water meter—if it moves, you may have a hidden leak
10. Exterior Hose Bibs & Spigots
- Test for leaks and adequate flow
- Insulate for winter protection
- Replace worn rubber washers
Seasonal Plumbing Tasks to Add to Your Checklist
Spring
- Inspect sump pumps and drains
- Check for pipe damage from winter cold
- Flush water heater to remove sediment
Summer
- Look for root intrusion in sewer lines
- Inspect irrigation systems
- Check water usage levels
Fall
- Insulate exposed pipes
- Disconnect outdoor hoses
- Drain and store sprinklers or irrigation hoses
Winter (in Southeast Texas, yes—it still matters)
- Check attic and crawlspace pipes for freezing risks
- Run a slow drip on freezing nights
- Keep cabinet doors open to warm pipes near walls
Red Flags That Require a Professional Inspection
While many items on this checklist are homeowner-friendly, certain issues call for a licensed plumber:
- Sudden drops in water pressure
- Frequent clogs or slow drains
- Discolored water or odd smells
- Signs of foundation shifting (possible slab leak)
- Water heater issues you can’t diagnose
Don’t guess when it comes to these problems. Call 409 Group and let our expert team step in.
