« on: 05 February 2017, 18:47:28 »

There are two 'O' Rings on the drain plug if my memory serves me correctly, an inner and outer.

You can unscrew it and pull it out to stage one to drain, and then pull it again to remove it completely.  :y

Though I'm sure you'd find suitable O rings from a proper hardware/tool merchant, a new drain tap is only cheap  :y

There are 2  rings, different sizes. Years ago I bought a Clarke Universal 'O'  Ring set from Machine Mart. The ) rings you want are F3, 5mm id 2.3mm cross section, and F4 7mm id 1.5mm crosss section. I expect any garage would have such a box. Pics follow of the plug and O rings.

Dealer will sell you a new drain plug which won't seal properly.  So one of those o-ring packs from a tool shop :y
