Ariston 65104261 Expansion Vessel 8L with PRV 61312668

Description

Ariston 65104261 Expansion Vessel 8L with PRV 61312668

The Ariston 65104261 Expansion Vessel 8L is an  spare designed to maintain stable system pressure in compatible Ariston boilers.

This complete assembly includes the Pressure Relief Valve (PRV) 61312668, ensuring full pressure protection and correct boiler operation.

The expansion vessel absorbs water expansion during heating cycles. If the diaphragm fails, symptoms typically include:

• Boiler losing pressure frequently

• Pressure rising to 3 bar when heating runs

• Water discharging from the safety valve

• Constant need to repressurise

Replacing the expansion vessel restores proper pressure control and prevents repeated PRV discharge.
