Biasi Garda / Parva / Riva Diverter Valve – Refurbished | Part No. BI1141500

When a combi boiler's diverter valve fails, the system can no longer switch flow correctly between central heating and domestic hot water. The result is either no hot water at the taps, no heating to radiators, or both functions running simultaneously and inefficiently. The Biasi Diverter Valve BI1141500 (Refurbished) is the correct replacement for the Garda M90F, Parva M90, Riva Compact M90E, and Riva Plus M90D ranges, restoring reliable and accurate hot water and heating switching.

This is a professionally refurbished genuine Biasi component — each valve is stripped, cleaned, seals inspected, and function-tested before dispatch. Minor cosmetic marks may be present, consistent with removal from a working boiler. Supplied with a full 12-month warranty. Original price: £59.99 — current sale price: £43.00.
