Don't Let Your Pipes Spring a Leak This Season
Don’t Ignore Your Pipes This Spring in Des Moines
Following these spring plumbing inspection tips can save you from expensive surprises as temperatures rise across Greater Des Moines:
- Check for leaks under sinks, around toilets, and along visible pipes
- Test your sump pump by pouring water into the pit before spring rains arrive
- Inspect outdoor faucets and hose bibs for freeze damage from the Iowa winter
- Flush your water heater to clear sediment buildup and improve efficiency
- Test for silent toilet leaks using the food coloring method
- Examine washing machine hoses for bulges, cracks, or wear
- Check water pressure with a simple gauge — ideal range is 40–60 PSI
- Run a water meter test to catch hidden leaks you can’t see
- Clear drains and gutters to protect your foundation from spring runoff
- Schedule a professional inspection for anything that looks off
Winter in central Iowa is hard on your home’s plumbing — even when nothing obviously breaks. Freeze-thaw cycles stress pipe joints, loosen seals, and leave behind hairline fractures that stay quiet all winter and then fail the moment water demand picks back up in spring. Add the heavy rains that typically roll through Des Moines in May, and you have a recipe for leaks, backups, and flooded basements.
The good news? Most of these problems are completely preventable. Research shows that regular maintenance can prevent up to 70% of plumbing failures before they become emergencies — and a focused spring walkthrough is one of the simplest things you can do to protect your home and your wallet this season.
Why Spring is the Best Time for a Plumbing Inspection
As we move into May 2026, the harsh Iowa winter is finally in the rearview mirror. However, the effects of those sub-zero temperatures linger within your walls and under your floors. Spring is the ideal time for a thorough plumbing check because it follows the period of greatest stress your pipes experience all year.
When water freezes, it expands with incredible force. Even if you didn’t experience a catastrophic flood in January, that expansion can weaken soldered joints in copper pipes or cause hairline cracks in PVC. As the ground thaws and the soil shifts around your home, underground lines are put under physical pressure. These “ghost leaks” might remain dormant while the ground is frozen, only to begin seeping as the spring thaw completes.
Furthermore, spring in Des Moines brings heavy rains. A plumbing system that is already struggling with a slow drain or a weak sump pump will quickly be overwhelmed by a thunderstorm.
By performing a proactive inspection now, you can extend the lifespan of your plumbing system by up to 10 years. If you’ve already noticed signs of trouble, such as damp spots or low pressure, consult our Burst Pipe Repair Des Moines IA Guide to understand the next steps.
Essential Indoor Spring Plumbing Inspection Tips
Inside your home, the “leak safari” begins in the kitchen and bathrooms. Small drips are more than just an annoyance; they are a primary cause of mold and structural rot. Since water damage repairs cost American homeowners an average of $3,000 per incident, catching a drip today is a major financial win.
Start by opening the cabinets under every sink. Look for “verdigris”—that greenish-white crusty corrosion on copper—or white mineral deposits on galvanized steel. These are “smoking guns” that indicate a slow, persistent leak. If you notice a lot of mineral buildup on your fixtures, it may be time to consider a Water Softener Des Moines IA to protect your pipes from the hard water common in Central Iowa.
Testing for Silent Toilet Leaks
A leaky toilet can waste up to 200 gallons of water every single day. That is enough water to fill a large hot tub every week! Often, these leaks are “silent,” meaning you won’t hear the water running.
To test this, perform the food coloring test: drop a few drops of blue or red food coloring into the toilet tank and wait 30 minutes without flushing. If color appears in the bowl, your flapper valve is worn and needs replacement.
Eliminating these “phantom flushes” is one of the best ways to save water this summer.
Inspecting Washing Machine Hoses
Washing machine hose failures are among the most common causes of catastrophic indoor flooding. Standard rubber hoses have a limited service life and should be replaced every five years.
During your spring inspection, feel the hoses for bulges, cracks, or frayed ends. We highly recommend upgrading to braided stainless steel hoses, which are much more resistant to bursting. If you’re leaving your home in Ankeny or Johnston for a weekend getaway, it’s a great habit to turn off the water supply valves to the machine entirely.
Maintaining Your Water Heater and Sump Pump
Your water heater and sump pump are the workhorses of your home. In Des Moines, these units work overtime during the transition from winter to spring.
Spring Plumbing Inspection Tips for Water Heaters
During the winter, cold groundwater requires longer heating cycles. This accelerates the settling of mineral sediment at the bottom of the tank. If you hear “popping” or rumbling sounds, that is often steam bubbles fighting through a layer of sediment—a phenomenon known as “kettling.” You can learn more about the signs of sediment buildup in a water heater to see if yours is at risk.
Flushing your water heater annually to remove this sludge improves efficiency and prevents the bottom of the tank from “cooking” and failing prematurely. While you’re there, check the anode rod; this “sacrificial” rod is designed to rust so your tank doesn’t. If the rod is depleted, your tank is next. If you see rust at the base or water pooling, you may need Water Heater Repair Des Moines IA immediately.
Keep an eye out for these signs your water heater is going out to avoid a cold shower.
Testing Your Sump Pump Before the Rain
In areas like Pleasant Hill or Waukee, a functional sump pump is the only thing standing between you and a flooded basement during a May downpour. Sump pumps often fail because they sit unused all winter, allowing the float switch to become stuck with dust or debris.
Perform a “bucket test”: pour five gallons of water into the sump pit. The float should rise, the pump should activate immediately, and the water should discharge quickly. Ensure the discharge pipe carries water at least 5 to 10 feet away from your foundation. If your pump is over 10 years old or makes strange noises, consider a Sump Pump Replacement Des Moines IA before the storm clouds gather.
Outdoor Plumbing and Sewer Line Health
The exterior of your home needs just as much attention as the interior. Freeze damage often hides just behind the siding, waiting for you to turn on the hose for the first time.
Spring Plumbing Inspection Tips for Sewer Lines
Spring is when tree roots “wake up” and aggressively seek out moisture. Because sewer pipes are often warmer than the surrounding soil and can have condensation on the outside, they act as a beacon for thirsty roots. About 30% of all clogs are caused by root intrusion.
Watch for “marshy” spots in your yard that don’t dry out, or gurgling sounds coming from your toilets when you run the sink. These are early warning signs of a sewer line issue. A professional camera inspection is the only way to truly see what’s happening underground, especially in older Des Moines neighborhoods with clay or cast iron pipes.
Checking Faucets and Aerators
Outdoor hose bibs are highly susceptible to winter damage. Even “frost-free” spigots can burst if a hose was left attached over the winter, trapping water inside the pipe.
Perform the “thumb test”: turn on the faucet and try to block the flow with your thumb. If you can stop the water easily, or if you hear dripping or spraying sounds inside the wall, you likely have a cracked pipe.
Indoors, check your faucet aerators. Hard water minerals can clog these small screens, leading to poor flow. Simply unscrew them and soak them in white vinegar overnight to restore full pressure. This is especially important for tankless water heaters, where scaling problems can affect the entire system’s performance.

What is the ideal water pressure for my home?
The ideal residential water pressure is between 40 and 60 PSI. Anything above 80 PSI is considered “hypertension” for your pipes and can cause premature wear on appliance seals and water heaters. If your pressure is too high, you may need a pressure-reducing valve.
High pressure is often a hidden cause behind those whistling noises in water heaters.
How do I check for hidden leaks?
The most effective DIY method is the water meter test. Ensure all water-using appliances (including ice makers and humidifiers) are turned off. Locate your water meter and look at the “low-flow indicator”—usually a small triangular wheel. If it’s moving, you have a leak. If you don’t have an indicator, record the reading and check it again after two hours of zero water usage. If the number has changed, water is escaping somewhere in your system.
When should I call a professional plumber?
While many of these checks are DIY-friendly, you should call a licensed professional for any of the following:
- You suspect a leak behind a wall or under a concrete slab.
- You have recurring clogs or sewage odors.
- Your water heater is leaking from the tank itself.
- You are uncomfortable performing technical maintenance like flushing a water heater or testing a main shut-off valve.
- You want a comprehensive, “Gold Star” inspection to ensure your home is fully protected for the year.
