Although there are many “life-changing” plumbing hacks online that claim to fix leaks, unclog drains, and save you money, many simply don’t work. Some can even cost you much more in the long run. The key is knowing the difference. Below are several plumbing hacks that really do work, along with a few that are best left to a professional plumber.
Hack That Works #1: Use a Sink Strainer
It may seem simple, but a sink strainer can save you money over time.
A sink strainer catches food scraps, hair, and other debris before they enter your drain. Using one in both your kitchen and bathroom sinks helps reduce clogs and extends the life of your plumbing system.
Remember to empty the strainer regularly so water continues flowing freely.
Hack That Doesn’t Work #1: Pouring Hot Water Down Every Drain
Many people believe pouring boiling water down a drain will solve any clog. Unfortunately, that isn’t true.
Although hot water may help loosen grease inside metal pipes, it can damage PVC piping. It also won’t remove hair, soap buildup, or other materials causing the blockage.
Instead of solving the problem, boiling water can push the clog farther into the pipe and create an even bigger issue.
Hack That Works #2: Locate Your Main Shutoff Valve
Your home’s main shutoff valve is usually located where the main water line enters the house.
If a pipe bursts or a major leak occurs, shutting off the water quickly can prevent serious water damage. Knowing where the valve is before an emergency happens can save valuable time and reduce cleanup.
Take a few minutes today to locate it—you’ll be glad you did.
Hack That Doesn’t Work #2: Using Chemical Drain Cleaners
Chemical drain cleaners may seem like an easy solution, but they often create more problems than they solve.
These products can damage older pipes and wear down O-rings in newer plumbing fixtures. They also fail to remove the root cause of many clogs.
Use chemical drain cleaners only as a last resort. If clogs continue returning, contact a professional plumber for a long-term solution.
Hack That Works #3: Use Your Water Meter to Find Hidden Leaks
Hidden leaks are more common than many homeowners realize.
To check for one, turn off every faucet and appliance that uses water, including your dishwasher and washing machine. Check your water meter, wait about 30 minutes without using any water, then check it again.
If the reading changes, there’s a good chance you have a hidden leak somewhere in your home.
Hack That Doesn’t Work #3: Flushing Disposable Wet Wipes
Many people assume wet wipes break down just like toilet paper.
In reality, most disposable wipes take months—or even years—to decompose. As they travel through your plumbing, they collect inside sewer lines, trap debris, and create stubborn blockages.
The safest option is to throw wet wipes in the trash instead of flushing them.
Hack That Works #4: Flush Sediment From Your Water Heater
Sediment naturally builds up inside a water heater over time.
Flushing the tank once a year improves efficiency, extends the lifespan of the unit, and helps provide consistent hot water throughout your home.
If you’re comfortable performing this maintenance yourself, it’s a valuable yearly task. Otherwise, a reputable plumber can handle it during a routine maintenance visit.
Hack That Doesn’t Work #4: Repairing Leaks With Duct Tape
Duct tape has plenty of uses, but repairing plumbing leaks isn’t one of them.
Leaks usually develop because fittings, seals, or gaskets have worn out. Covering the leak with duct tape only hides the symptom—it doesn’t fix the problem.
If you use duct tape, treat it as a temporary measure until you can make a permanent repair or call a plumber.
Hack That Works #5: Run Cold Water When Using Your Garbage Disposal
Using your garbage disposal correctly can help prevent clogs and extend its lifespan.
Always run cold water before, during, and for about 15 seconds after using the disposal. Cold water helps solidify grease and food particles so the disposal can chop them into smaller pieces instead of allowing them to stick inside your pipes.
This simple habit keeps your kitchen plumbing flowing more efficiently and reduces the risk of future clogs.
Hack That Doesn’t Work #5: Grinding Everything in Your Garbage Disposal
Garbage disposals are convenient, but they aren’t designed to handle every type of food waste.
Avoid putting these items down the disposal:
- Grease or cooking oil
- Coffee grounds
- Eggshells
- Pasta or rice
- Bones
- Fibrous vegetables like celery or corn husks
These materials can clog your pipes, dull the disposal blades, or cause the motor to work harder than necessary. Instead, throw these items in the trash or compost them when possible.
