By late September the storms have mostly moved on and the yard has dried out. This is the best time of the year to walk your property and check the things monsoon season quietly rearranged, because problems found in September are cheap and problems found in December are not.
None of this takes special tools. Most of it takes an hour and a flashlight. Here’s what we’d check if it were our house.
Start Outside With Drainage and Grading
Water is the thing that moved, so start where it moved.
Walk the perimeter of the house and look at how the soil sits against the foundation. Ground should slope away from the building. If a summer of runoff has cut a channel toward the house or washed gravel away from the base of a wall, water is now pooling against your foundation every time it rains. Correcting that is landscaping work, not plumbing work, but it protects your plumbing all the same.
Check your canales and roof drains next. Anything that carries water off the roof needs to be clear, and monsoon debris is exactly what clogs them. A blocked canale sends water sheeting down the wall and saturating the ground right where your supply and drain lines run.
Look at hose bibs while you’re out there. Storms move gravel and debris, and a hose bib with soil piled around it stays wet, which is how corrosion starts.
Check Your Sewer Cleanout

Find the cleanout. It’s typically a capped pipe near the foundation, on the side of the house closest to the street. If you’ve never located it, do that now rather than during a backup at ten at night.
Confirm the cap is present, intact, and threaded down properly. A missing or cracked cap during monsoon season means runoff has been carrying silt and debris directly into your sewer lateral all summer. Replace it if it’s compromised. This is the single cheapest preventive item on the entire list.
Clear gravel, mulch, and plant growth away from the cleanout so it’s accessible. If we ever need to get to it in a hurry, minutes matter.
Walk the Interior Fixtures

Inside, you’re looking for changes rather than disasters.
- Run every drain in the house and time them. A sink that empties noticeably slower than it did in June is telling you something settled over the summer.
- Flush every toilet, including the ones in guest bathrooms nobody uses. Listen for gurgling from other fixtures while it drains.
- Check under every sink with a flashlight. Look for damp cabinet bottoms, water stains, or mineral crust on fittings.
- Look behind and under the washing machine. Supply hoses fail, and they usually give warning in the form of bulges or dampness at the connections.
- Check the water pressure at a couple of fixtures. A whole-house drop that appeared over the summer is worth investigating.
If more than one drain has slowed, that’s not several fixture problems. That’s one main line problem, and drain cleaning is the appropriate next step rather than working on them individually. The usual culprits behind repeat clogs are worth knowing either way.
Finish the outdoor walk by checking irrigation valve boxes and exposed supply connections for standing water. A soggy box after the surrounding yard dries may point to a small underground leak rather than leftover rain, which is pipe repair territory. Note the location and compare it again the next morning.
Look at the Water Heater
Your water heater just finished the hardest four months of its year. Give it five minutes.
Look at the base of the tank for moisture, rust, or white mineral crust. Check that the discharge pipe from the relief valve is dry. Listen during a heating cycle for rumbling or popping, which indicates sediment. If the unit is in an attic, confirm the overflow pan is present and its drain line actually goes somewhere.
If it’s been more than a year since the tank was flushed, this is the right month to do it. Our water heater service covers flushes, anode rod replacement, and repairs, and doing it in the fall means you’re not making that decision in an emergency.
What Not to Handle Yourself
A few things on the list belong to us rather than to you.
Don’t open a sewer cleanout that’s under pressure. If there’s any sign of backup, opening the cap releases contaminated water into your yard and onto you. Call instead.
Don’t pour chemical drain cleaner into a slow line to see if it helps. It usually doesn’t, it can damage pipe, and it makes the eventual professional visit more hazardous.
Don’t ignore a gas smell, indoors or out. Leave the building, don’t operate switches, and call from outside. Gas line service is not a wait-until-Monday item.
Common Questions About Fall Plumbing Maintenance
Is a fall checkup really necessary if nothing went wrong?
Nothing going wrong is the point. Storm debris settles gradually, so a line that handled the summer fine can still be carrying material that becomes a blockage later. A walkthrough costs you an hour.
Should I have the sewer line camera inspected every year?
Not every home needs it annually. Homes with older pipe, mature trees near the sewer route, or a history of backups are the ones where a post-monsoon inspection earns its keep. Our sewer line service covers the camera inspection and any repair it turns up.
My drains are slightly slower but nothing has backed up. Can it wait?
Slightly slower is the early stage, and it’s the cheapest point to address it. Waiting doesn’t make it better, and blockages tend to complete themselves at inconvenient times.
How do I find my main water shutoff?
It’s usually near the meter at the street or where the supply enters the house. Find it now, make sure it turns, and make sure everyone in the household knows where it is. That knowledge is worth more than most maintenance. Our guide to what to do during a plumbing emergency covers when to use it.
Can you do the whole checklist for me?
Yes. A residential plumbing inspection covers all of it, and we’ll give you a written list of anything worth addressing along with what can safely wait.
