Seasonal Plumbing Checklist: Preparing Your Home for Summer and Winter

Plumbing doesn't care what season it is. But the weather does affect it more than most homeowners realize.

Pipes expand and contract. Water heaters work harder in some months than others. Outdoor fixtures either freeze or bake, depending on the time of year.

A little seasonal maintenance goes a long way toward avoiding the kind of plumbing emergency that shows up at the worst possible time. Here's a simple checklist for getting a home's plumbing ready for both summer and winter.

Preparing for Summer

Summer brings more water use overall. Sprinklers run longer. Kids are home and showering more. Guests visit and use extra bathrooms. All of that adds strain to a system that could already be due for attention.

A quick seasonal check goes a long way here. Many homeowners bring in a plumber Hot Springs trusts for this exact reason, just to get ahead of anything before it becomes a bigger problem mid-summer.

• Check outdoor faucets and hose bibs. Look for drips, low pressure, or corrosion around the connection point. A small leak outside can waste a surprising amount of water over a full summer.
• Inspect the irrigation system. Sprinkler lines, drip irrigation, and backflow preventers should all be checked before heavy use begins. A cracked line underground can go unnoticed for weeks while quietly running up the water bill.
• Test the sump pump. Summer storms can bring heavy rain fast. A sump pump that hasn't been tested since last year is a danger not worth taking.
• Look at water heater settings. Many households can safely lower the water heater temperature slightly during summer months, which reduces energy use without reducing comfort.
• Watch for slow drains. Warmer weather often means more cooking, more dishes, and more grease going down kitchen drains. A slow drain in spring can turn into a clogged one by midsummer.
• Inspect the water heater's pressure relief valve. Heat and pressure both increase demand on this small but important part. A quick check now can prevent a bigger issue later.

Preparing for Winter

Winter is where plumbing problems tend to get expensive fast, mostly because of freezing. Water expands as it freezes, and that expansion is exactly what cracks pipes.

• Disconnect and drain garden hoses. Leaving a hose attached to an outdoor spigot can trap water in the pipe, which then freezes and cracks it.
• Insulate exposed pipes. Pipes in crawl spaces, garages, or exterior walls are the most vulnerable to freezing. Foam pipe insulation is inexpensive and takes very little time to install.
• Know where the main shutoff valve is. If a pipe does freeze or burst, being able to shut off the water fast can be the difference between a minor repair and a major one.
• Let faucets drip during extreme cold. A small trickle of water keeps pressure from building up inside a pipe, which lowers the odds of it freezing and cracking.
• Check the water heater before the heavy-use season starts. Cold weather increases hot water demand for showers, laundry, and dishes. A water heater already struggling in the fall is more likely to fail in January.
• Seal gaps near pipes. Cold air sneaking in through small gaps around pipes entering the home is a common, overlooked cause of frozen pipes.

Homeowners vs. Plumbing Professional: What Tasks Can Each Handle

What Homeowners Can Handle

Most of the seasonal checklist above is doable without any special tools or experience. Some examples include:

• Draining a hose
• Checking for drips
• Testing a faucet

These are all things any homeowner can knock out in an afternoon.

What Needs a Professional

A few tasks are worth handing off, though:

• Winterizing an irrigation system. Blowing out sprinkler lines properly requires an air compressor and some know-how. Doing it wrong can leave water trapped in the lines, which then freezes and cracks the pipe anyway.
• Insulating pipes in hard-to-reach areas. Crawl spaces and tight corners around a water heater can be difficult to access safely, and missing a spot defeats the purpose.
• Diagnosing a water heater that's acting up. Strange noises, inconsistent temperature, or a pilot light that won't stay lit are signs worth having a professional look at before the unit fails.
• Anything involving the main shutoff valve if it's stuck or corroded. Forcing a stuck valve can snap it off entirely, rendering a simple task into an emergency.

NOTE: If it involves opening up a wall, working with gas lines, or needs specialized equipment, it's worth the cost of a professional visit.

Warning Signs That Shouldn't Wait for the Next Season

Some plumbing issues don't follow a seasonal schedule and need attention right away, regardless of the time of year:

• Water stains on ceilings or walls almost always mean a leak somewhere above.
• A sudden, unexplained spike in the water bill often points to a hidden leak.
• Gurgling drains can mean a blockage is forming in the main line.
• Popping or rumbling sounds from the water heater usually mean sediment has built up in the tank.
• Noticeably low water pressure across the whole house frequently signals a bigger issue, not just a fixture problem.
• A constantly running toilet usually means a worn flapper or fill valve that's wasting water around the clock.
• Musty smells near a sink, tub, or floor drain can indicate a slow leak feeding mold growth out of sight.

None of these should wait until "the next seasonal check." Catching them early is almost always cheaper and less disruptive than waiting for them to get worse.

Plumbing doesn't ask for much. A checkup before summer, another before winter, and a little attention to the warning signs in between. That's usually enough to avoid the emergencies that cost homeowners the most.

​Most plumbing problems don't show up overnight. A slow drip outside turns into a wasted summer's worth of water. An uninsulated pipe turns into a burst one on the first hard freeze. A seasonal check catches these while they're still small, before they turn into a flooded basement or a repair bill nobody planned for.

Frequently Asked Questions

How often should pipes be inspected for seasonal wear?

Twice a year is usually enough for most homes, once before summer and once before winter. Older homes or homes with a history of plumbing issues may benefit from more frequent checks.

What temperature is considered a freeze risk for pipes?

Pipes are generally at risk once temperatures drop below 20°F, especially in unheated spaces like garages, attics, or crawl spaces.

Is it really necessary to drip faucets in winter?

For homes with exposed or poorly insulated pipes, yes. It's a simple move that meaningfully lowers the risk of a frozen or burst pipe.

Can lowering the water heater temperature in summer actually save money?

Yes, though the savings are modest. It reduces standby heat loss and slightly lowers energy use, especially on tank-style water heaters.

Should sprinkler systems be shut off completely in winter?

In colder climates, yes. Irrigation systems should be winterized and blown out to remove water from the lines before the first hard freeze.
