What the technician found
The technician identified the cold-water expansion valve, described as the CWE valve in the work record, as constantly dripping. This is a valve-component example, not evidence that the cylinder tank itself had a leak. A discharge symptom still needs assessment on each system; it should not be diagnosed from a photograph alone.
The repair and checks recorded
The technician installed a new cartridge in the valve. The recorded repair was to that component: the note does not describe replacing the whole valve assembly or the cylinder. A genuine equipment photograph from the attendance is shown below.
The work record confirms cartridge installation but does not include a measured discharge rate, a pressure reading or a documented post-repair leak-test result. We do not claim those checks or a longer-term result. This historical cartridge repair is not the same scope as a current whole-valve replacement offer.

An overflow that keeps running?
Do not cap, block or adjust a relief or expansion-valve outlet. Keep clear of hot discharge and wet electrical equipment. Read our running-overflow guidance and leaking-cylinder safety guide; the source needs professional assessment before a repair is chosen.
A component repair and a new cylinder solve different problems. Our repair-or-replace guide explains what to assess. If a replacement is recommended, use the replacement-only calculator to compare supported packages subject to a site visit—not to price this repair or reserve attendance.
This historical job is not a price or guarantee for another property. Current offers have their own stated scope and require diagnosis. Same-day attendance must be arranged and confirmed by phone; repair completion depends on the fault and parts.
