Water Tank Repair in Illawarra
Professional water tank and pump repair across Wollongong, Kiama, Shellharbour and the greater Illawarra region. Leaking tanks, failed pumps, broken valves, overflow problems and plumbing connection repairs.
Water tank repair covers fixing faults in rainwater and mains-pressure storage tank systems including the tank fittings, pump, valves, overflow, inlet/outlet connections and associated plumbing. In Illawarra, water tank repairs cost $120-$800. Valve and fitting replacements cost $120-$250. Pump repairs — including pressure switch replacement, impeller faults and motor issues — cost $200-$500. Overflow pipe repairs cost $150-$300. Common tank problems include leaking outlet fittings caused by UV degradation of poly fittings, pump losing prime from air leaks in suction lines, failed float valves on mains-top-up systems, blocked first-flush diverters, and cracked overflow pipes. Tank pumps typically last 5-10 years and may need pressure switch, capacitor or seal replacement before full motor failure. A licensed plumber should service tank plumbing annually, checking connections, backflow devices and pump operation to maintain reliable water supply.
Tank Problems We Fix
Leaking Tank Fittings
Repair or replace leaking inlet, outlet and overflow fittings. UV-degraded poly fittings and corroded brass connections are common in Illawarra's coastal environment.
Pump Not Working
Diagnose and repair pressure pumps — tripped breakers, failed pressure switches, blocked filters, seized motors, air locks and impeller damage.
Float Valve Failure
Replace failed mains-top-up float valves that cause overflow or don't refill the tank. Ensure correct water level management and prevent water waste.
Overflow Problems
Repair blocked, cracked or disconnected overflow pipes. Ensure overflow directs to stormwater and doesn't flood around the tank or building foundations.
Backflow Device Service
Test and replace backflow prevention devices on mains-connected rainwater systems. Annual testing required by regulations to protect drinking water supply.
Pump Replacement
When pump repair isn't economical, we supply and install quality replacement pumps. Correctly sized for your tank and household demand.

These are typical price ranges for the Illawarra and NSW, drawn from published 2026 industry pricing data — not a quote, and not our fixed prices. What your job actually costs depends on access, the age and condition of the plumbing, parts, and whether it is after hours. We give you a fixed price before we start work, so you are never guessing.
