Now, first of all I'm not a Golan salesman or anything like that. I've noticed a lot of talk of people using a Pingel but I'm thinking a petcock with detents would be nice to have when reaching under the tank to change position. I contacted Golan Products about comparing their product with a Pingel. Here is what they sent me. It's strange there is talk of a stainless steel ball bearing but I don't see it in the pic. They mention "Second Generation" and claim
112 oz. per minute. Also, not sure what they are referring to about setting the "Reserve". Comments or Feedback ??
