Homeowners are often curious about when to call emergency plumbers, but it's never ideal to have to make that call. The best-case scenario is contacting a plumber who has been adequately researched online or a trusted referral from a friend or family member. Then, if some emergency plumbing situation does arise, property owners aren't taking a chance on someone with whom they aren't familiar.
Unfortunately, there are times when it is necessary to call for emergency plumbers, so understanding what is considered high priority and what isn't is helpful in case the situation presents itself. First, it's an emergency if the house has a major water leak or spray that can't be stopped. Another reason is if there is sewage backing up into the home. There are health issues associated with sewage backup, so it's necessary to take care of it immediately. Finally, if the water isn't working at all, a plumbing professional can help.
One way to avoid emergency plumbers having to make a house call is by becoming familiar with where everything in the plumbing system is and how it works, including how to shut off the water.
