AN OVERFLOWING TANK MEANS A CEILING AT RISK

If water is running constantly from an external overflow pipe, the cold water tank or cistern in your loft is failing to shut off — and somewhere upstream, water is filling the tank faster than it can leave through the overflow. Eventually the tank either splits, the overflow blocks, or both — and the next thing to give is the ceiling below.

Loft tank failures, ballcock seizures and cistern leaks are some of the most preventable water damage emergencies in Perth. EcoGas stops the inflow, drains safely, repairs the fault and tests the system before leaving — usually all within a single visit.

SIGNS OF A TANK OR OVERFLOW PROBLEM

Catch these early — the ceiling below pays the price if you don’t

OVERFLOW RUNNING

Continuous trickle or pour from an external overflow pipe — usually visible from outside the house.

DAMP LOFT CEILING

Damp patch on a ceiling directly below the loft — water has reached the ceiling void.

RUNNING SOUND

Sound of constantly running water in the loft — tank is filling without stopping.

SLOW CISTERN

Toilet cistern that never stops filling or makes a constant hissing noise.

LOW HOT WATER

Low or no hot water — failed cold feed from the tank to the cylinder.

DISCOLOURED WATER

Brown or cloudy water from cold taps fed by the tank — sign of corrosion or contamination.

ECOGAS'S WATER TANK REPAIR SERVICE

BALLCOCK & VALVE FIXES

The most common loft tank failure is a stuck or perished ballcock — the float arm that shuts off the inlet valve when the tank reaches the right level. Replacement is a 30-minute job with the right part on the van.

TANK REPLACEMENT

For cracked tanks, perished base seals, or tanks past replacement age, we install a new properly-insulated polypropylene tank with all associated pipework and overflow connections.

WHAT PERTH SAYS AFTER A WATER TANK FIX

Rebecca W. — Perth

Came home from work and the front of the house was wet from the overflow pipe running constantly. EcoGas sent someone the same evening, found the ballcock had perished, replaced it, tested everything before leaving. Reasonable price for an after-hours job.

Stephen B. — Perth

Old galvanised loft tank had finally split — water everywhere in the loft. EcoGas drained it safely, removed it, installed a new polypropylene tank with proper insulation, all in a single afternoon. Highly recommend.

Maria L. — Perth

Toilet cistern never stopped filling, water bill creeping up. EcoGas diagnosed a worn inlet valve, replaced it in 20 minutes, problem gone. Cheaper than the water bill would have been over the year.

Joe T. — Perth

Loft tank overflow was actually blocked, causing the tank to overflow into the loft instead of outside. EcoGas cleared the overflow, fitted a new ballcock for good measure, and re-routed the overflow pipe properly. Top job.

WATER TANK FAQS

IS A CONSTANTLY RUNNING OVERFLOW AN EMERGENCY?
Treat it as one. Running overflows mean a tank is filling beyond its design level and the ceiling below is the eventual casualty. Same-day repair is strongly advised — by the time you can see damp on a ceiling, structural damage is usually well underway. We prioritise overflow calls for fast dispatch.
Yes — most loft tanks have an isolation valve on the inlet pipe just before the tank. Turning it clockwise will stop the inflow and let the overflow drain off. Call us before turning off the entire house mains — we can usually talk you through finding the right valve over the phone while we dispatch.
Modern polypropylene tanks last 25–30 years with proper insulation. Older galvanised steel tanks (pre-1990) are usually past replacement age and we recommend swapping them for a plastic equivalent. Older asbestos cement tanks should be replaced for health reasons regardless of condition — we handle these with proper safe-removal protocols.
Yes, very similar — usually a failed flush valve or inlet valve in the cistern. Fix is the same day, often under an hour. Replacing the valve costs far less than the water you’ll waste over a year of slow refilling.
Usually only the cold water tank-fed supply is briefly off (typically 30–60 minutes). Mains-fed taps (often the kitchen cold tap) and the toilet usually keep working in most homes. We always check before isolating anything and warn you what will be affected.
Yes — and we strongly recommend it for every Perth loft tank. Proper insulation prevents the most common cause of winter loft tank failures. We fit insulation jackets to tanks and lag the cold water pipework as a standard part of any replacement, or as a standalone job.
