Rt and Stubones. I understand about the effect of the electrical potential on zincs, but all things being equal (I.e.electrical potential) a pencil zinc in a vessel in use should deteriorate faster than a zinc when the vessel isn't in use: 1) the concentration of zinc in within a heat exchanger has to be higher when the water inside is stagnant than when it is flowing, hastening deterioration; 2) the associated erosion from flowing water is higher than with stagnant water. I check my zincs more frequently in the summer when the vessel is in use than when it is sitting at the slip.
