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.
