Anode on only one pump is corroding
Anode on only one pump is corroding
(OP)
I have a condition with vertical turbine pumps in a wetwell pumping chlorinated water. Chlorine residual is 3-5 mg/L. TDS is about 1200 mg/L. All the pumps are fitted with anodes on the pump column. The anodes on the jockey pump (1 of 4) shows extensive corrosion on anode(fully crusted over). Anodes on other pumps show only minor corrosion. The pump with the corroded anodes has significantly more run time than the other pumps. The pump columns and bowls on all the pumps look to be in excellent condition so there is no concern at this time about pump corrosion. We just don't know why these anodes corrode more than the other anodes. What would cause the anodes on the jockey pump to corrode more than the other pumps?

It may be that this one is not connected properly and it is not working.
Take a good look and see if the crust is anode corrosion product or not.
