Have you ever encountered a story that sounded so impossible that ended up being true? Then, there are those stories that seem to be completely believable that ended up being completely false. In the plumbing world, there are many such stories.

That’s why we prepared this quick guide to some of the most common plumbing myths circulating today.


Certainly, repairing a leaking faucet is usually a very simple task for a trained professional. But that doesn’t mean that you should put off getting it fixed.

Even a tap that loses a drop every 5 to 10 seconds can be responsible for over 400 gallons of wasted water in a single year. Not only does that kind of waste have serious environmental repercussions, it will also end up costing you more on your utility bills.

If a defective faucet is dripping onto a countertop or inside the cabinet, the resulting dampness can bring about harmful mold that can aggravate allergy and respiratory symptoms.


Under certain circumstances, it is possible for the internal pressure of a water heater to climb so high that it explodes, launching itself upwards through the floors above and hundreds of feet into the air.

This is an uncommon occurrence thanks to a safety feature called the TPR valve. The TPR valve, which stands for temperature pressure release, automatically opens to release some water from the tank when the internal pressure and temperature approach dangerous levels.

To ensure your home’s safety, you should occasionally test your TPR valve by placing a bucket under the drain tube attached to it and lifting its tab to allow water to come out. If nothing comes out when the valve is open, or if water doesn’t stop flowing after you’ve closed it, you may have a defective TPR valve that needs to be replaced.


When you use a plunger, the force creates pressure between the drain in the clog. That pressure is what eventually can dislocate the clog. When a blockage forms further down in the drainpipes, a plunger becomes ineffective.

In those cases, special tools may be necessary. These tools include augers and a process called hydrojetting that sends a concentrated stream of pressurized water through the drainpipes to smash away even the most stubborn blog.
