MSJ Plumbing & Drainage LTD provides 24/7 emergency plumbing, drainage and heating services for homes and businesses across its service areas.
Comprehensive diagnostic and repair service resolving an internal leak on a boiler plate heat exchanger, including hydraulic seal restoration, full internal chamber clean-up, system re-pressurisation, and operational safety testing.
The customer contacted MSJ Plumbing after noticing a recurring drop in boiler pressure accompanied by visible water dripping from beneath the boiler casing. Upon removing the front casing and conducting a full internal inspection, our heating engineer traced the source of the water escape directly to a leaking seal connection on the plate heat exchanger.
Because water inside the boiler cabinet can quickly corrode internal manifolds, sensors, and the main PCB electronics, immediate isolation and remedial servicing were carried out to restore a watertight seal and protect the appliance.
Safely isolated the electrical and water supplies, depressurised the primary heating circuit, and resolved the leak originating from the plate heat exchanger manifolds and O-ring seals.
Thoroughly cleaned the internal boiler casing, hydraulic block, and surrounding components, removing accumulated moisture, scale residue, and corrosion deposits caused by the leak.
Recharged the sealed heating system via the filling loop to optimal manufacturer operating pressure (1.2 – 1.5 bar) and vented trapped air from the internal pump and heat exchanger assembly.
Fired up the boiler across both domestic hot water (DHW) and central heating modes. Verified zero leaks under peak thermal expansion and confirmed the boiler is operating safely and in full accordance with industry standards.
