We’ve all been there. It’s 11 pm on a Tuesday, you’ve just brushed your teeth, and you hear a distinct drip, drip, drip coming from somewhere behind the bathroom wall. Or perhaps you’ve flushed the toilet, only to watch in horror as the water level rises instead of falls, threatening to breach the rim like a mini-tsunami.
At that moment, panic sets in. Do you grab a bucket and hope for the best until morning? Do you attempt a YouTube-inspired DIY fix that involves duct tape and wishful thinking? Or do you pick up the phone?
Knowing exactly what counts as a plumbing emergency & when you really need to call a plumber is the difference between a minor inconvenience and a flooded living room. At ALK Emergency Plumbers, we’ve seen it all across Essex—from the “just a loose washer” that wasn’t, to the ceiling-collapsing catastrophes that definitely were.
This guide will help you decipher the warning signs, saving you stress, money, and potentially your floorboards.
What counts as a plumbing emergency?

Not every plumbing hiccup requires a siren-blaring dash to your front door. A dripping tap is annoying, sure, akin to Chinese water torture, but it can usually wait until standard business hours. A plumbing emergency, however, is defined by immediacy. If the issue poses a risk to your health, your property’s structure, or your ability to access basic necessities (like water or heat), it’s an emergency.
Here are the scenarios where you shouldn’t hesitate to dial an emergency plumber.
Burst pipes
This is the Hollywood blockbuster of plumbing disasters. When a pipe bursts, it can release gallons of water into your home in a matter of minutes. The damage to electrical wiring, drywall, flooring, and furniture can be catastrophic and expensive. If water is gushing uncontrollably, this is priority number one. Check our blog for more details.
Major leaks
There is a distinct difference between a nuisance drip under the sink and a major leak. If you have a steady stream of water that you cannot contain with a bucket, or if water is seeping through light fittings or bulging out of the ceiling, you have a major leak. Water travels fast and can cause structural rot if left unchecked for even a few hours.
Blocked drains and toilets
We aren’t talking about a sink that drains a bit slowly. We mean a complete stoppage. If your toilet won’t flush (and you only have one toilet in the house), or if sewage is backing up into your bathtub or sinks, this is a serious health hazard. Raw sewage carries bacteria and pathogens that you definitely don’t want floating around your family home.
No hot water in winter
In the height of July, a cold shower might be refreshing. In the depths of a British winter, a lack of hot water or heating is dangerous, particularly for the elderly, young children, or those with vulnerable immune systems. If your boiler packs up when the temperature drops, it constitutes a valid emergency.
Gas leaks
This is the most critical item on the list. If you smell sulphur (often described as rotten eggs), feel dizzy, or hear hissing near your gas appliances, evacuate the property immediately. Do not touch any light switches. Call the national gas emergency number, and then call a Gas Safe registered engineer. This is life-threatening and requires immediate professional intervention.
Overflowing toilet
If the water in the bowl keeps rising and the usual trick of jiggling the handle doesn’t work, you’re in trouble. An overflowing toilet can quickly turn your bathroom into a splash zone of the worst kind. If you can’t stop the flow using the isolation valve, you need help fast.
When you really need emergency plumbing services

Sometimes, the signs aren’t as obvious as a waterfall in the hallway. However, certain symptoms act as warning lights on a car dashboard—ignore them at your peril. You need to call a professional if:
- You can’t find or turn off the stopcock: If water is leaking and the main shut-off valve is seized up or inaccessible, you cannot control the situation. A plumber can freeze the pipe or locate the external stopcock to halt the flow.
- Water damage is spreading visibly: If a damp patch on the wall doubles in size within an hour, the leak is active and aggressive.
- Foul odors are taking over: A persistent smell of sewage indicates a breach in your waste pipes or a serious blockage deep in the system. This isn’t something air freshener can fix.
- The pipes are singing: Banging, clanging, or whistling pipes (often called water hammer) can indicate high pressure or loose pipework, which can lead to a rupture if ignored.
- You suspect a gas leak: As mentioned, never DIY gas work. If you have even a slight suspicion of a leak, you need a qualified engineer.
Preventative measures to avoid plumbing problems

While we love helping our customers, we know you’d prefer not to see us under emergency circumstances. A little maintenance goes a long way in preventing those midnight panic attacks.
Inspect your pipes
Regularly check under sinks and around your boiler for signs of moisture or corrosion (rust). Catching a small leak now prevents a burst pipe later.
Watch what you flush
Toilets are not trash cans. “Flushable” wipes rarely are. Stick to the three Ps: pee, poo, and (toilet) paper. Sanitary products, wipes, and cotton buds are the leading causes of blocked drains we see in Essex.
Insulate for winter
Frozen pipes are a major cause of winter bursts. Insulate your pipes in the loft, garage, and any other unheated areas with foam lagging. It’s a cheap fix that saves thousands in potential water damage.
Know your stopcock
Find your main water shut-off valve (stopcock) today. Test it to make sure it turns. If a pipe bursts, this valve is your best friend.
FAQ
What should I do before the plumber arrives?
If possible, turn off the main water supply at the stopcock. Turn on cold taps to drain the system. If it’s an electrical risk, turn off the electricity at the mains. Move furniture/valuables away from the affected area.
Can a dripping tap be a sign of something more severe? How does it affect my water bill?
Yes, a dripping tap can sometimes indicate underlying issues within your plumbing system such as worn-out washers, faulty seals, or even pipe damage. While it may seem like a minor inconvenience, a dripping tap wastes water over time and can significantly increase your water bill if left unaddressed. Fixing a dripping tap early can prevent the problem from becoming worse and save you money in the long run.
What should I do if I notice low water pressure?
Low water pressure can be caused by various issues, such as a partially closed valve, pipe blockages in your internal pipes, or even external factors like water supply disruptions in your area. First, check if all valves, including the stopcock, are fully open. If the issue persists, inspect for any visible leaks or blockages in your plumbing. It’s best to contact a professional if you’re unable to identify the cause, as persistent low pressure could indicate a more serious problem that needs expert attention.
