As a homeowner, it's very important to have the number of an emergency 24-hour plumbing service on your phone's speed dial just in case you run into a problem with your plumbing that requires immediate assistance. If you can't imagine a scenario that would require such a speedy turnaround, here are some possible situations that you may find yourself in.
The most drastic problem that will require a plumber is dealing with a burst pipe. This problem is more common in the winter when sub-zero temperatures can cause water lines in your house to reach below freezing, leading to the water freezing and potentially bursting the pipe. Not only will you have water all over your floor and potentially damaging items, but you won't have working water as well.
However, the temperature outside does not necessarily have to be cold to experience a pipe burst. Another possibility is having old galvanized plumbing in your home that rusts from inside the pipe. A burst of this type of pipe can happen when you least expect it, requiring the whole section of pipe to be replaced.
An emergency plumber can come to your home and make the necessary repairs to the pipe to get water flowing once again.
Water Heater Failure
Having your water heater fail unexpectedly may be just as bad as having no water at all. You don't realize how much you depend on having hot water in your home until it is gone. The main problem is that you'll be unable to take a shower since cold water is out of the question for showing. While you can get by with just using cold water for cleaning purposes, you won't be able to get things as clean as you could if you were using hot water to kill off the germs.
Emergency plumbers do have hot water heaters on hand for emergency replacement purposes. The selection won't be huge, but there will be no need to order a water heater and wait several says for it to arrive.
It's possible that you have a plumbing clog that is causing problems with your drains and toilets flushing, but you are in a bind where you need the problem resolved quickly. For example, you may have guests that are coming over to stay with you or a party where many people will be using the bathroom. An emergency plumber will get the problem fixed quickly.
