Some plumbing problems are minor – annoying, sure, but not urgent. A slow-draining sink, a slightly dodgy tap, or maybe even that mystery drip you’re pretending not to hear.

Then there are the other problems – you know, the ones that make you panic-text your group chat. The ones that often involve terrible smells, broken pipes, and water going somewhere it absolutely should not be going. In other words: plumbing emergencies.

Here are five of the most common plumbing emergencies we deal with on a day-to-day basis, and when you should stop trying to handle it yourself and pick up the phone.

1. Burst Pipes (or Pipes on the Verge)

Burst pipes are no joke – they’re truly one of the most dramatic (and costly) plumbing issues out there. And why do they almost always seem to strike when it’s cold, you’re tired, or you’ve just finished mopping the floor?

So, what are the signs you’re on the verge of one? Typically, you’ll start to hear unusual banging or rattling when the taps are on. You might also notice a sudden drop in water pressure, damp patches appearing on walls or ceilings. Or, you know, you might also experience an actual explosion of water in your kitchen. (As a plumber in Essex, I’ve seen this far too often. And yes, it is scary the first time it happens.)

If you do think you’re dealing with a pipe on the verge of bursting, it’s imperative that you act quickly. Shut off your water supply immediately and call a plumber in to take a look. Don’t try to tape it or clamp it – it won’t hold. You need a professional repair, or it’ll only get worse and more expensive to fix.

2. Overflowing Toilets

This has to be up there with every homeowner’s worst-case scenario; one second you’re flushing like normal. The next? The water’s rising, fast. You freeze. You panic. You start Googling things you wish you didn’t have to Google.

The bad news is, if a toilet is blocked badly enough to overflow onto your floor, there’s usually something more serious going on in your pipes. And even if you manage to temporarily fix it with a plunger, that pressure build-up could cause issues elsewhere in your system.

And yeah – overflowing toilets are gross. But they’re actually worse than just being unpleasant; raw sewage contains bacteria and pathogens that can spread if not dealt with quickly and professionally. So if it starts to overflow or gurgle, don’t wait – make a call to a plumber and have them come out for a visit right away. Not doing so can mean taking the risk that your bathroom becomes a bio-health hazard. 

3. No Hot Water

You’d be surprised at how quickly life becomes ten times more difficult when you lose your access to hot water. No more showers, potentially no heating – and if you’ve got kids and pets in the house, things can get messy fast.

So, what causes hot water to cut out? It could be your boiler, your thermostat, or a broken heating element – or you might just be dealing with a leak in your hot water system. It could even be something electrical, which is why it’s not usually a case of flipping a switch or waiting it out.

(Also – don’t risk an electric shock by tinkering with something you don’t understand. Please.)

If you’ve checked your thermostat and boiler settings and the issue isn’t obvious, call in a pro. A plumber will be able to identify the problem properly and fix it without trial-and-error guesswork (or further damage).

4. Blocked or Collapsed Drains

Unfortunately, a block drain is one of those plumbing problems that you’ll likely smell before you see. And if you’ve ever experienced even a whiff of this specific odour before, you’ll know how quickly you want it gone.  

Aside from  foul smell near your sinks, gurgling sounds and slow drainage are also signs of a blocked drain. In the worst-case scenario, it might not be a simple blockage at all; tree roots can infiltrate external drainage pipes, old clay pipes can collapse, and over time, your entire system can clog with grease, wipes, hair, or whatever else people are flushing down the loo these days.

Chemical drain cleaners might help in very mild cases, but they can also corrode your pipes if overused. And they definitely won’t touch tree roots or structural damage.

If multiple fixtures are affected (e.g., your sink, shower, and toilet all draining slowly), that’s usually a system-wide issue, which means it’s time to call a professional.

5. Leaking Water Heaters or Tanks

A little puddle next to your water heater might seem harmless, but it’s truly not. Leaks in or around your water tank can mean pressure build-up, corrosion, or valve failure. In some cases, it’s a small seal that needs replacing. In others, it’s a sign your system is failing and could become dangerous if not handled properly.

Water heaters are also pressurised, which means if they malfunction badly enough, they can explode. (Not in a Hollywood blockbuster kind of way – more like “sudden boiling water in your utility room” kind of way, which is worse.)

Don’t try to patch it up or ignore it! Get it checked by a professional. 

So, When Should You DIY and When Should You Not?

The general rule? If water is going where it shouldn’t… or not going where it should… and you don’t understand why? Call someone.

A quick fix can easily become a long-term disaster if you’re not careful. And yes, we get it: it’s tempting to try. We all want to save a few quid and feel clever doing it. But unless you’re confident in what you’re dealing with, you’re risking damage to your home, as well as your bank balance.
