Plumbing FAQ Database
Answers to water leak, pipe corrosion, drain blockages, and water heater repairs with links to service silos.
Water Leaks
What causes water leaks?
Water leaks inside wall cavities or ceilings are usually caused by thermal expansion stress in PPR pipe joints, scale rust in copper couplers, high pressure pump surges, or AC condensation drain overflows. Read more on our water leak detection page.
How much water can a leak waste?
A pinhole pipe leak operating at 4-bar booster pressure can waste up to 3,000 gallons of water per week. This can rapidly increase water bills. Check our guide on why water bills rise to diagnose causes.
How do plumbers find hidden leaks?
We employ non-destructive check technologies, including thermal imaging cameras to locate damp lanes and acoustic microphones to pinpoint the hiss of pressure leaks behind tile layers. Learn about hidden leak checks.
Pipes
How long do PVC pipes last?
Standard PVC wastewater piping can last 20 to 30 years under normal slab conditions. However, using aggressive acid cleaning products can degrade joints and cause early leaks, requiring early pipe replacement.
When should pipes be replaced?
You should replace supply networks if you notice repeated rusty hot water, lime scale flakes in mixer aerators, or multiple pinhole failures. Learn about our pipe replacement services.
What causes pipe corrosion?
Domestic water storage configurations combined with high ambient heat speed up oxidation in copper lines. Check our guide on corrosion diagnostics to prevent pipe bursts.
Drains
Why are drains blocked?
Drains are blocked by cooking fats solidifying inside vertical stacks, bathroom sand sludge trapping hair particles, and AC slime backing up. We advise professional mechanical blocked drain cleaning to clear waste safely.
How often should drains be cleaned?
We recommend preventative drain cleaning every 12 months for villa lateral drains and apartment floor traps to prevent sudden flooding.
Water Heaters
Why is my water heater leaking?
Ceiling cylinder leaks usually result from calcified heating elements increasing internal pressure, or a failure in the temperature-pressure relief safety valve. See our water heater leak repair page.
How long do water heaters last in Dubai?
Horizontal ceiling water heaters typically last 4 to 6 years due to mineral scaling. Scheduled flushing extends cylinder lifespan. Review our water heater maintenance checklist.
