DIY Tips To Stop Leaks

Stopping leaks in your home can often be done with some DIY methods, depending on the type and severity of the leak. Here are some tips:

  1. Find the leak. Common sources include faucets, pipes under sinks, showerheads, and toilet flappers.
  2. Use a wrench to gently tighten loose nuts or connections in pipes or faucets.
  3. Turn off the water supply and replace the gaskets and washers.
  4. If the leak comes from threaded pipe connections, wrap the plumber’s tape around the threads before re-tightening.
  5. Use epoxy putty or a pipe clamp to temporarily patch small leaks.
  6. If your toilet leaks, adjust the float so the water stops filling about one inch below the top of the overflow tube.
  7. Replace the toilet flapper or the fill valve in your tank.
  8. Inspect your seals. You may need to caulk or add new grout to prevent water from seeping through.
  9. Regularly inspecting pipes, faucets, and appliances for signs of wear and tear can help prevent leaks from developing.

Keep in mind that these tips are only for minor issues. You should call a professional plumber to avoid further damage or complications for significant leaks or those that are hard to reach. Safety is important, so if you’re unsure how to fix a leak, it’s best to leave it to the professionals.

When To Call a Plumber for a Leak

Deciding when to call a plumber for a leak can be tricky. On one hand, you want to avoid overreacting to a minor issue and spending more money than necessary. On the other hand, you want to avoid letting a minor leak become a major problem, which can also be costly.

Call a plumber if you notice these problems:

  • Water pooling around your washing machine, dishwasher, water heater, or under your sink
  • Hearing dripping or running water sounds in walls or ceilings
  • An unexplained increase in your water bill
  • Slow-draining bathtub or shower
  • Your basement is flooded
  • Gurgling sounds coming from your toilets or drains
  • You suddenly have no hot water
  • Your pipes are frozen
  • Water pressure is low in multiple places around your house
  • Sewer odor in your home

If you notice any of these things, it’s best to call a plumber. A professional can find and fix leaks before they become big problems and save you money in the long run.

Is it safe to use drain cleaner when I have a clog?

While drain cleaners can quickly fix slow drains, they often contain harsh chemicals that can damage your pipes over time. A mixture of vinegar and baking soda or a plumber’s snake can be a safer alternative for minor clogs. For persistent issues, it’s best to consult a plumber.

How can I prevent future plumbing leaks?

  • Check all your pipes, appliances, and plumbing fixtures regularly.
  • Make sure your water pressure is good.
  • If you have hard water, think about getting a water softener.
  • Replace old or corroded pipes.
  • Fix leaks right away.
  • Don’t use harsh chemical drain cleaners.
  • Insulate pipes in unheated areas.
  • Be careful what you put down the drain.
  • Use appliances per their instructions.
  • Have a professional plumber check your plumbing yearly.

How can I tell if I have a hidden water leak?

To find hidden water leaks in your home:

  • Keep an eye on your water bill for any unexpected increases.
  • Check your water meter to see if it’s moving when no water is used.
  • Look for signs of moisture or damage, like mold, mildew, or discoloration on walls and ceilings.
  • Listen for dripping sounds and do a food coloring test in the toilet tank to find hidden leaks.

If you can’t find the leak, it’s best to call a professional plumber to inspect your home thoroughly.
