Emergency plumbers in Swansea, what to do and who to call

First steps in a plumbing emergency

Before calling a plumber, take these steps to limit damage:

Burst pipe or major leak:

1. Turn off the main stopcock (usually under the kitchen sink, in the garage, or under the stairs, find it now before you need it)
2. Turn off the boiler
3. Open cold taps to drain the system and relieve pressure
4. Turn off the electricity if water is near electrical fittings (and consider calling an electrician too)

Blocked drain or sewage backup:

1. Stop using all toilets, sinks, and drains in the property
2. If sewage is backing up into the property, do not attempt to clean up until the blockage is cleared (sewage contains pathogens)

Gas leak:

1. Do NOT call a plumber, call the National Gas Emergency Service on 0800 111 999
2. Leave the property, don't use switches or flames
3. Only return when cleared by the emergency service

What counts as a plumbing emergency?

True emergencies that justify out-of-hours rates:

• Burst pipe with uncontrollable water flow
• Major leak causing visible structural damage or water near electrics
• No water to the property (not just reduced pressure)
• Sewage backing up into the property
• Boiler failure in extreme cold (particularly for elderly occupants)

Issues that can wait until normal hours:

• Dripping tap (put a towel under it)
• Slow-draining sink or bath (try a drain snake first)
• Running toilet cistern
• Cold radiators (check for air, bleed the radiators first)
• Low water pressure (check if it's affecting the whole street, contact Dwr Cymru/Welsh Water)

Calling out a plumber at 2am for a non-emergency costs you 2–3x the day rate. Many issues can wait a few hours.

Finding a reliable emergency plumber

In a genuine emergency, you can't always vet thoroughly. But these checks are quick:

• Google the number before calling, check reviews on Google Maps. A plumber with no Google presence is a risk.
• Ask for Gas Safe registration if the problem involves the boiler or gas pipework, check the number at gassaferegister.co.uk
• Confirm the call-out fee over the phone before they come out
• Ask if they're local to Swansea, a local plumber can attend faster and is more accountable

For planned emergency cover (landlords, property managers), set up an account with a local plumbing firm in advance. Most Swansea plumbing companies offer priority response contracts for landlords.

Dwr Cymru / Welsh Water handles issues with the water main up to your boundary: call 0800 052 0130 for leaks in the street or if you have no water affecting the whole area.
