Things That Go Bad Fast If You Don’t Check Them Monthly

Some things can go south quick if you’re not checking on them regularly. A monthly once-over doesn’t take long, but it can save you from bigger problems (and bills) later.

Water Filters

Whether it’s for the fridge, under the sink, or on a well system, those filters clog fast.

A dirty filter puts stress on the whole system and cuts your water pressure. Check them monthly—even if you don’t change them every time, you’ll catch the early signs it’s overdue.

Fire Extinguishers

They sit quietly in the corner, but that pressure gauge needs a monthly glance.

If it’s dropped too low or shows damage, it won’t do a thing when you actually need it. A few seconds of checking can keep your kitchen—or barn—from turning into a bigger disaster.

HVAC Filters

Your heating and cooling system can’t work right if it’s choking on dust.

Filters clog faster in dusty rural homes, especially with pets or nearby fields. Monthly checks help you catch when it’s time to swap it out—waiting longer just costs you more on your electric bill.

Sump Pumps

If you’ve got a basement or crawl space, that sump pump better be ready to work.

Give it a quick test monthly—power it on and make sure it’s actually pumping. One good storm can flood everything if it fails when you weren’t looking.

Smoke and CO Detectors

Batteries die without warning, and a dead detector won’t do you any good.

Press the test button once a month and listen for the beep. You don’t want to find out it wasn’t working after the fact.

Water Softener Salt

If you’re running a softener, letting the salt level drop means the whole system quits doing its job.

It doesn’t take long to glance in the tank and toss in a few bags if needed. Skip it too long and your pipes, appliances, and skin will notice.

Fridge and Freezer Temps

Thermostats can slip out of range without you realizing it.

Check that fridge stays below 40°F and the freezer under 0°F. Too warm, and food spoils faster—even if it still feels “cold.”

Pest Traps

Sticky traps and bait stations don’t last forever.

If they’re full or dried out, they’re useless. A quick once-a-month sweep can keep you ahead of an infestation instead of reacting to one.

Extension Cords in Use

If you’ve got cords plugged in long-term, they need regular checks for fraying, heat, or damage.

Especially in barns or sheds, critters love to chew. Don’t assume they’re safe just because they still work.

Water Heater Pressure Relief Valve

This one’s overlooked constantly.

Pull the valve monthly to make sure it isn’t clogged. If it won’t release water or drips afterward, it might be time for a new one. A stuck valve can lead to serious pressure problems later.
