When the Weather Turns: How Temperature Swings and Heavy Rain Affect Your Plumbing

Living in Denver, Colorado, means learning to expect the unexpected when it comes to weather. One day it’s sunny and 70°F — the next, you’re scraping ice off your windshield. But those wild temperature swings and sudden downpours don’t just stress out your wardrobe — they can wreak havoc on your home’s plumbing system.

At Silver Monkey Plumbing, we see a spike in service calls every time the weather flips or a big storm rolls through. From cracked pipes to flooded basements, here’s how Mother Nature can mess with your plumbing — and how to protect your home before it’s too late.

🌡️ 1. Sudden Temperature Drops Can Crack Pipes

Colorado’s rapid temperature changes — especially in fall and spring — cause water inside your pipes to expand and contract. Over time, this repeated stress weakens joints and fittings, leading to leaks or full-blown pipe bursts.

It’s not just freezing that’s the problem — even a 20–30°F swing in a single day can cause old metal or PVC pipes to shift and crack.

Watch for warning signs like:

Dripping sounds in walls

Unexplained wet spots or mold

Sudden drops in water pressure

💡 Pro Tip: Insulate your exposed pipes, even if it’s not winter yet. Denver’s unpredictable cold snaps can strike any time.

If you do notice leaks or pressure loss, call Silver Monkey Plumbing right away. We can inspect your system using thermal imaging and pressure testing tools to catch small problems before they become big headaches.

🌧️ 2. Heavy Rain Can Flood Sewer and Drain Systems

When Denver gets hit with one of those intense rainstorms, all that water has to go somewhere — and often, it finds its way into your home’s plumbing system.

Older neighborhoods with shared or aging sewer lines are especially prone to backflow issues, where stormwater overloads the system and pushes sewage back into drains or toilets.

That’s not just gross — it’s a serious health hazard.

Signs of a sewer backup include:

Gurgling drains or toilets during rainfall

Slow-draining tubs or sinks

Foul odors from basement drains

💧 Prevention Tips:

Install a backflow prevention valve on your main sewer line.

Have your drains and sewers professionally inspected and cleaned annually.

Keep gutters and downspouts clear to reduce excess runoff near your foundation.

Silver Monkey Plumbing offers camera inspections and sewer line cleaning for Denver-area homes — fast, affordable, and handled by experienced local techs who know how to deal with Colorado’s tough soil and aging infrastructure.

🧱 3. Foundation Shifts from Wet Soil

After long dry spells followed by heavy rain, Denver’s clay-rich soil expands and contracts — putting stress on your home’s foundation and underground plumbing. This can cause subtle pipe movement, small leaks, or even full main-line breaks over time.

If you notice recurring dampness in your basement, unexplained high water bills, or the sound of running water when all faucets are off, you could have a hidden leak beneath your slab.

Silver Monkey Plumbing uses acoustic leak detection and advanced pressure sensors to find underground leaks without tearing up your floors or yard.

🌬️ 4. Drain Odors After Rainstorms

Have you ever noticed a weird sewer smell in your house right after a heavy rain? That’s often due to pressure changes in your home’s plumbing vents or saturated drain fields.

When outside air pressure shifts quickly — which is common during Colorado thunderstorms — it can push sewer gases back through your plumbing system.

If the smell lingers, or comes with gurgling drains, it could mean your vent pipes are clogged or your sewer line needs maintenance. Silver Monkey Plumbing can inspect and clear your vents to restore proper airflow and stop odors at the source.

🛠️ How to Protect Your Denver Home from Weather-Related Plumbing Issues

You can’t control the weather — but you can stay ahead of the damage.

✅ Schedule seasonal plumbing inspections. Especially in spring and fall when temperature swings are extreme.

✅ Clean gutters and downspouts regularly. This keeps rainwater away from your foundation.

✅ Seal cracks in exterior walls and around pipe openings.

✅ Have your sewer line hydro-jetted once a year to prevent clogs before heavy rains hit.
