Brupaks 29L boiler with tap

I've got this on order and am thinking about how to adapt the tap for sparging. I assume I can easily remove and replace the tap as and when required. Anyone know the aperture size so I can get a suitable tank coupler?

I wasn't planning on drilling it but wanted the option of fitting something to the tap or in place of it for sparging.

I understand your point.
I shall wait and see when it arrives.
