Need a 24/7 Plumber in Cardiff? Here’s What to Do When Plumbing Disasters Hit After Hours
It’s 11:47pm on a Sunday. Your ceiling is dripping. The toilet just overflowed. Your boiler is making noises you’re pretty sure it shouldn’t. Who do you call?
If you live in Cardiff, the answer is simple: DMK Plumbing and Heating — your trusted 24/7 plumber in Cardiff.
Plumbing disasters don’t wait for business hours, and neither do we. In this post, we’ll cover what to do during a plumbing emergency, what a 24-hour plumber actually handles, and how to avoid getting fleeced by cowboys when you’re under pressure.
Why You Might Need a 24/7 Plumber in Cardiff
Plumbing problems don’t just inconvenience you — they escalate quickly and cause massive damage if left unchecked. Here’s when you need to act immediately:
Burst pipes flooding your home
Blocked toilets or overflowing waste water
No heating or hot water in freezing conditions
Leaking boilers or gas smells
Flooded kitchens or bathrooms
Overflowing outdoor drains
Any of these can wreck your property, create health hazards, or both. That’s why it’s crucial to have a 24/7 plumber Cardiff homeowners can rely on.
What to Do First in a Plumbing Emergency
Before you grab the phone, take these steps to control the damage:
Shut off your water supply – Use your stopcock to cut off water at the mains.
Turn off the heating system – Prevent pressure build-up or boiler overheating.
Avoid using electrics near leaks – Water and power don’t mix. Be smart.
Contain the water – Towels, buckets, bowls — stop it spreading.
Call a professional 24/7 plumber – And give them a clear explanation.
The faster you act, the less it’ll cost you later.

There’s a risk of flooding or water damage
You smell gas or suspect a boiler leak
You’ve lost heating and it’s sub-zero outside
A toilet has blocked and you only have one in the property
Wait until morning if:
It’s a dripping tap or minor leak with no overflow
Your boiler’s lost pressure but isn’t leaking
A second bathroom or toilet still works
We’ll still help — but we won’t charge emergency rates if it can wait.
