(Above) A demonstration on how the water thimble is inserted on a removed tap aerator and (left) a closeup of the water saving kit containing a set of thimbles. The kits are available for free at any of the nine PBAPP customer service centres in Penang.
THE humble water thimble can reduce the gush of water flowing out of your tap or shower head.
It looks like a large clothing button with three or four small holes in the middle and it is a cheap solution for everyone to help cut water consumption in Penang and keep their water bill low.
