Leaking water supply lines inside UAE walls and floors are often only discovered when water stains appear on ceilings or walls — by which point significant damage has occurred. Contractors UAE locates and repairs water supply line leaks across Dubai, Sharjah and Abu Dhabi using non-invasive detection before any cutting work begins.

Understanding your UAE property's water supply system helps in diagnosing and preventing problems. UAE municipal water supply arrives at each building at 2–6 bar pressure, measured at the DEWA meter. From the meter, the supply enters either a pressurised distribution network (typical in apartments) or a rooftop storage tank and pump system (common in older UAE apartment blocks and villas). Rooftop tank systems operate at gravity pressure — typically 1–2 bar — which is adequate for most fixtures but may be inadequate for high-flow shower systems or commercial applications. Modern UAE villas typically use a pressurised booster pump to maintain 3–4 bar throughout the building regardless of tank water level or simultaneous demand.
The cold water supply pipe within UAE properties is almost universally CPVC in buildings constructed between 1990–2015 and PPR in newer construction. CPVC under UAE conditions develops a specific failure pattern: the pipe itself remains strong for 30+ years, but the solvent-cement joints — particularly those made by less experienced plumbers using incorrect solvent-cement ratios — can separate when the CPVC pipe experiences the UAE summer thermal cycling (hot water pipes reaching 60–65°C surface temperature in unventilated roof voids). This joint separation is the source of most UAE concealed pipe leak events.
Leak repair: using pipe repair clamps, push-fit fittings or cut-and-replace sections to address leaking joints, pinhole corrosion or cracked pipe sections. New pipe installation: running water supply lines to new appliances (washing machine, dishwasher, water purifier), new bathroom additions, or kitchen relocations. Pipe replacement: replacing aged galvanised or deteriorated CPVC supply lines with PPR — our preferred material for UAE water supply installations because of its welded (not glued) joints, excellent resistance to UAE water chemistry, and low maintenance requirements. Pressure testing: using a gauge pressure test at 1.5× working pressure to verify system integrity before concealment of any new or repaired pipe run.

PPR (polypropylene) with heat-fusion welded joints is our first recommendation for UAE water supply — it is immune to the joint failure that affects CPVC, resists UAE water chemistry, and has no maintenance requirements. CPVC remains a reliable and cost-effective option when correctly installed.
Check the DEWA meter with all taps and appliances off — if the meter moves, there is an active leak. Monitor your bill for unexplained increases. Our thermal imaging survey can locate most concealed leaks without wall opening.
Yes — we use thermal imaging and acoustic detection to locate the leak without unnecessary concrete breaking, then repair the minimum area required.
New supply line installation for a single appliance costs AED 250–600 depending on the run length and access. Full property replumbing is priced after a site survey.
