Water dispensor leaking

I read other reviews to determine the secondary valve was the most likely problem. The reviews also told me what steps to take to get at the valve to replace it. The whole process took about 20 minutes. After turning the water back on I noticed a pin hole leak in the suppply line. I replaced the length of plastic tubing. This too was easy. If there is a next time, I will plan ahead to replace the supply line as a precautionary measure.
