Diverter Valve Faults on Combi Boilers
17 October 2026 | Leyton Boilers
Worn diverters cause hot water delays or heating staying on when only hot water is requested. Replacement is a common mid-life repair on busy combi boilers.
Diagnosis distinguishes diverter issues from sensor or board faults to avoid misquoted repairs.
Leyton Boilers stocks common diverter assemblies for faster London repairs.
