5 Times You Should Call a Plumber

Water Leak From Pipe

Many plumbing repairs can be performed on a do-it-yourself basis. When your water pressure is low, you can clean the showerhead, check the water meter valve, or do several other easy repairs. When the trap under your kitchen or bathroom sinks leaks, you can tighten up the existing trap or purchase a new, inexpensive trap. But with so many plumbing repairs easily within your reach, how do you determine when should you call in a plumber?

You Have a Rapid Water Supply Line Leak

It's the classic moment that triggers a plumber's visit: a water line bursts and causes major flooding throughout the house. While not common, this does occasionally happen. When it does, you need to be ready to act fast.

First, look for any intermediary water supply cut-off valves located near to the leak. If you are lucky, you might locate either a knife (ball valve) or knob-style cut-off valve that shuts off water to the leak only and not to the entire house. Failing that, locate your home's main water shut-off valve and turn it off. After shutting down the water, locate a plumber that can come immediately.

You Have No Water in the House

In instances when water stops flowing within your house, it is localized around one area, such as a bathroom sink or shower. But rarely will water stop flowing to your entire house.

Check all water outlets within the house to confirm that none of them are receiving water. Be sure to check both the hot and cold water supplies. Often, if there is a problem with the water heater and hot water is no longer being delivered, the cold side is still operable.

If you still cannot get the water to run, you may have a serious problem. It is possible that the buried water pipe leading from the streetside water meter to your house has burst or has been severed, diverting water intended for your house. Or the leak may be centered around the water meter.

You Have a Rapid Drainage Line Leak

If your kitchen sink or bathroom sink leaks from the trap directly below the counter, that is a fairly common issue that most homeowners can fix with simple tools and materials. Simply turn off the water, get under the sink, and replace the trap. In kitchens, the leak may be emanating from the garbage disposal. In this case, fix or replace the garbage disposal.

But drainage lines extend far beyond the sink cabinets and are not always so accessible. When a drainage line is actively leaking and is sealed up behind a wall or under a floor, you need to take immediate action. Calling a plumber is the most expedient way to fix this problem and prevent further damage to the drywall, paint, subfloor, or floor covering.

You Have a Sewer Line Leak or Gaseous Odors

A broken or blocked sewer line often manifests itself in your yard in the form of slowly accumulating pools of murky, smelly water or mushy soil. Or strange events happen indoors, like toilets filling when you run the sink or bathtubs filling with wastewater. You can always dig up the sewer line, locate the broken or clogged sewer pipe, then fix or replace it. But this type of do-it-yourself fix can take, at the least, several full days of back-breaking work.

The sewer line is the only line that carries all of your home's wastewater out from toilets, sinks, showers, tubs, dishwashers, and washing machines. Your home cannot function without this line; all activities are paralyzed until you can fix this.

This is why it is so important to call in a plumbing company for this repair. The company can do a sewer line video inspection through the sewer line clean-out entry point. Augering out the sewer line with a motorized drain snake may fix the problem. If the line is irreparably blocked or broken, it must be dug up and replaced.

Your Water Heater Has a Natural Gas Leak

If you suspect any sort of gas leak from any source, call 911 or the fire department and leave your house immediately. Once you're at a safe distance, call your gas company. Once your home is deemed safe, you can return and investigate the source of the leak—and only then might you call a plumber to fix a potential issue with your water heater. Natural gas build-up is extremely combustible, so it's better to take the most cautious route.
