Common House Water Tank Problems We Fix

• Cracks or fractures in the tank body — we seal and reinforce them to restore durability and prevent leaks and structural weakness
• Rust and corrosion on metal tanks — we treat, clean, and recoat the surface for long-term protection
• Leaking seams or loose fittings — we tighten, reseal, and replace faulty joints to stop water loss and maintain pressure
• Damaged or worn protective linings — we repair or reline the tank interior to prevent contamination and material degradation
• Water tank contamination — we provide water tank cleaning to remove bacteria and sediment buildup so your water stays clean and safe
• Overflow and drainage issues — we inspect and adjust float valves and drainage systems to prevent spillage and flooding
• Base or foundation damage causing imbalance — we assess and correct the base to stabilise the tank and prevent further damage

Signs Your House Water Tank Needs a Repair

• Visible leaks or damp spots — water marks or pooling around the tank base signal a leak, which can quickly lead to bigger structural damage if ignored
• Low water pressure — a sudden drop can point to cracks, pipe blockages, or a damaged outlet valve; checking it early helps prevent full system failure
• Discoloured or smelly water — rusty, greenish, or foul-smelling water suggests contamination from rust, algae, or bacteria, a health concern and a sign the tank needs cleaning or repair
• Cracks or bulging on the tank surface — visible cracks, dents, or bulges indicate structural stress and, if ignored, can lead to leaks or tank collapse
• Increased water bills — a leaking tank can waste water continuously without you noticing, so a sharp rise in your bill may point to a hidden leak
• Slow refilling or overflow — a tank that takes too long to refill or overflows often may have a damaged or blocked float valve, pump, or internal mechanism
• Sediment in water — sand, rusty flakes, or dirt in your tap water means the tank is overdue for cleaning or internal repair
