181051 Vaillant Ecotec Plus 831 Expansion Vessel

Note this is not a Vaillant branded part but a Zilmet branded part - the product description does not make this point clear although I understand this product was an OEM part on older Vaillant boilers. It needs to be clear as Zilmet branded vessels can be purchased for less then Vaillant stamped vessel's.

Genuine part all fitted and working.

Appears identical to the originally-fitted item (same Italian manufacturer's label etc.) Was already pressurised when unpacked. Worked as it should on installation.

GREAT PRICE. Far cheaper than in my local plumbing shops.
