A plumbing emergency can happen at any time — a burst pipe at 3 AM, a leaking radiator on Christmas Day, or a blocked toilet during a dinner party. When it happens, you need to act fast to minimise damage and get professional help on site as quickly as possible.
This guide covers the most common plumbing emergencies in Dartford, what you should do immediately, and how to get an emergency plumber to your door.
Step 1: Turn Off the Water
The single most important thing you can do in a plumbing emergency is turn off the water supply. This stops the flow and prevents further damage while you wait for help.
- Internal stopcock: Usually located under the kitchen sink or in a downstairs cupboard. Turn it clockwise to shut off.
- External stopcock: Found in the pavement outside your property, under a small metal or plastic cover. You may need a stopcock key to turn it.
- Isolation valves: If the leak is from a specific appliance (toilet, washing machine, tap), look for a small isolation valve on the pipe feeding it. Turn the slot with a flathead screwdriver so it's perpendicular to the pipe.
Tip: If you don't know where your stopcock is, find it now — before you need it. It's one of the most important things every homeowner should know.
Step 2: Minimise Damage
Once the water is off, take these steps to limit the damage:
- Place buckets, bowls, or towels under active leaks
- Move electronics, furniture, and valuables away from the affected area
- If water is near electrical outlets or appliances, turn off the electricity at the consumer unit
- Open taps to drain remaining water from the system (especially if you've turned off the mains)
- Take photos of the damage for your insurance claim

Common Plumbing Emergencies in Dartford
Burst Pipes
Burst pipes are most common during cold snaps when water freezes and expands inside the pipe. Dartford's mix of older properties (with copper and lead pipework) and newer builds means burst pipes are a year-round risk. Signs include: sudden loss of water pressure, damp patches on walls or ceilings, and the sound of running water when no taps are on.
Leaking Radiators
Radiator leaks often start small — a drip from a valve or a weep from a corroded joint — but can escalate quickly if left untreated. If you notice a leak, turn off the radiator valve and place a towel underneath while you wait for help.
Blocked Drains and Toilets
A blocked toilet or drain can cause sewage to back up into your home, which is both unpleasant and a health hazard. If plunging doesn't clear it, don't keep trying — you risk making the blockage worse. Call a plumber who has the right equipment (drain rods, CCTV cameras) to diagnose and clear the blockage properly.
Boiler Failures
A boiler breakdown in winter leaves you without heating and hot water. While we're not Gas Safe registered for boiler repairs, we can help with the plumbing side — frozen condensate pipes, radiator issues, and hot water cylinder problems.
How Much Does Emergency Plumbing Cost?
Our emergency call-out starts from £120, which includes diagnosis and the first hour of work. Most common emergencies (burst pipes, leaks, blocked drains) are resolved in a single visit. We always tell you the cost before starting any work — no surprises.

How to Prevent Plumbing Emergencies
- Insulate exposed pipes in lofts, garages, and under floors before winter
- Know where your stopcock is and check it turns easily (they can seize up if not used)
- Don't ignore small leaks — they always get worse
- Service your boiler annually to catch problems before they become emergencies
- Don't flush anything except toilet paper — wet wipes, cotton buds, and sanitary products cause most blockages
