I am using the following water cooler as my chlorine dispenser,

it works like a dream apart from the tap (button release) which has a metal spring and over time rusts and needs replacing. The hole in the cooler is 3/4" (19mm).
I was wondering if anyone else has used plastic taps and am looking for recommendations for one that pours well and doesn't drip.
I came across this link from the forums here and liked the look of this one. I am not in the USA so don't know where to get the equivalent in Australia where I am.
At one point in the past i used the chlorine drum and this drum cap tap which has a similar tap part.

But I found it dripped where the black cap part meets the white cap part, so you had to keep the drum up and tilt it on its side when you want to use it. I found the whole thing messy and it was better to pour all into the cooler.
Any recommendations on which tap is the best for the job would be appreciated and preferably from somewhere that will ship to Australia at a reasonably price like E-Bay.
P.S.-
I was also considering replacing the spring in the existing tap (button release) with a noncorrosive spring but not sure what type of metal spring would be best for chlorine.
