brite-tap

So this is for those of you who have the Britetap nipple waterer. Does yours leak? I am having issues with 1 of my 2 nipples leaking. I'm not sure if it gets stuck or what but it will run 5 gallons of water out of it when it leaks. Have any of you had this issue, if so, how did you resolve it...

Does anybody use a brite-tap waterer? If so: How do you like it? Any algae growth? Easy to clean/install? Do your chickens like it? How many chickens do you have per brite-tap? Thank you guys in advance for the insight! :)
