There are several cases when it is advisable to contact an emergency plumber as soon as possible. For example, what is perceived to be a minor leak could be a sign of something much more serious; the street-side water meter or the pipe carrying water underground might have burst; a sealed drainage line could be leaking causing damage to the wall or floors; or a pipe might have burst in the upstairs bathroom, causing water to seep through the ceiling.
Here is a website which outlines the kind of services an emergency plumber undertakes; https://emergencyplumbercheltenham.com/
As you can see from the site, they do all types of emergency repairs, from taps, to pipes, radiators toilets and much more. So if you experience leaks like those stated on the site or even others, its best to call your local emergency plumber for advice.
Although some of these problems can be repaired on a do-it-yourself basis, it is vital to ensure that these problems don’t occur again. And by doing it yourself, you might just aggravate the problem.
So you should call an emergency plumber when you find a leak or a burst pipe or even a leaking boiler. It’s better to call then to put it off as something minor, only for it to biter your wallet later down the line.
