Position Overview

Our dedicated Flush Valve & Ballcock Repair Technicians specialise in diagnosing, servicing, and replacing malfunctioning toilet fill mechanisms, bowl ballcock valves, and dual-flush assemblies. We address continuous running water, weak or incomplete flushing, and persistent overflows to protect your bathroom from internal water damage and prevent elevated water meter bills.

Key Responsibilities & Procedure

01

Isolation & Safe Cistern Drain-Down

Turn off fixture isolation valves and safely drain toilet tanks prior to component removal to avoid accidental bathroom spillage.

02

Valve, Flapper & Connector Replacement

Inspect, remove, and replace faulty fill valves, siphon assemblies, flush seals, worn flappers, and flexible braided supply connectors.

03

Water Level & Float Height Calibration

Adjust tank water levels and accurately set float heights to meet manufacturer specifications and ensure optimal flush volumes.

04

Gasket, Seal & Hardware Inspection

Check toilet bowl seals, doughnut tank-to-bowl rubber gaskets, and close-coupled mounting hardware for degradation or concealed seepage.

05

Seat Descaling & Limescale Cleaning

Clean valve seats and eliminate mineral deposits or scale buildup that hinder reliable closing and cause micro-leakage.

06

System Testing & Silent Fill Verification

Test the repaired assembly under mains pressure to confirm complete positive shut-off, rapid silent refilling, and leak-free operation.
