Zip AQ2 Expansion Vessel and Check Valve (3.5 bar)

Zip AQ2 Expansion Vessel and Check Valve (3.5 bar)

Will the pipework accommodate expanded water without hot water entering any supply pipe connected to a cold water draw-off? If expansion in the cold water main is restricted, e.g. by a valve or meter, an expansion vessel and other relevant accessories MUST be fitted.

The Zip Unvented Accessories are specially designed for those situations.
