In PBO 402 p 64 there was an article on a scew in sink plug developed by Mr Charles Jolly. The phone number no longer works. Does anyone know where to get these? My plug regularly pops out when under way
he sold them at jumbles for a while, don't know if he's still around. unfortunately the thread of the plastic nut that held them in place was inadequate and pops apart regularly. (i know, i've got 2 of them)
We use rubber wine bottle stoppers, they have a ribbed plug section that grips and fits all our sinks perfectly. Sold in packs of 2 from ironmongers/kitchenware shops, bought ours from Harwoods in Yarmouth.
