Reported Issue Upstairs Cylinder Leak
Immediate Action Mains Shut-Off & Drain-Down
Assessment Full Replacement Required

Incident Overview

On November 6, 2026, our emergency response team attended a property following reports of a major water leak originating from the upstairs hot water cylinder. Escaping water had penetrated through the upstairs floor space and severely affected the downstairs kitchen ceiling and recessed light fittings.

Immediate Emergency Actions Taken

01

Main Water Supply Isolation

Immediately located and shut off the main incoming water supply to isolate the pressurised system and halt further water ingress into the floor cavity below.

02

Emergency Hot Water Cylinder Drainage

Connected drainage hoses and initiated a controlled, full drain-down of the upstairs hot water cylinder to relieve internal water volume and stop active dripping downstairs.

03

Complete Emptying to Lowest Accessible Point

Successfully drained the failed cylinder down to its lowest accessible point, ensuring no residual stored water could continue saturating the kitchen ceiling below.

Findings & Required Remedial Work

Following containment of the leak, our engineer conducted a full structural and safety inspection of the affected areas:

A

Hot Water Cylinder Failure

The cylinder unit itself has suffered internal structural failure and cannot be repaired safely. A full hot water cylinder replacement is required.

B

Downstairs Kitchen Ceiling Saturation

The kitchen ceiling sustained noticeable water damage, structural saturation, and plaster weakening due to water tracking through from the upper floor.

C

Electrical Safety Hazard (Ceiling Light Fittings)

Water was observed actively dripping through the downstairs kitchen ceiling light fixture. This poses a significant electrical short-circuit risk requiring professional electrical inspection alongside ceiling repairs.

WARNING – Electrical Hazard: Do not attempt to use or switch on the affected kitchen lights until a qualified electrician has inspected the wiring and fixtures for water ingress. Ensure power to the lighting circuit remains isolated at the consumer unit (fuse box).
