One drip every five seconds you say.
60 / 5 = 12 or 12 drips per minute.
12 * 60 = 720 or 720 drips per hour
Lets use the assumption that there are 90,922 drips in a gallon of water. How many hours will your dripping take to fill a one gallon bucket? Math below....
90,922 / 720 = 126.28 hours
So roughly every 5 1/4 days you waste one gallon of water. That is not so much in the big picture.
90,921.8 drops of water in a gallon, or for you metric folk – 20,000 drops in one litre
You will get better help if you show us the problem. Take a moment and snap a picture or two. Post them here and maybe you will get lucky and as simple fix is in order.
