Locke Well & Pump Company

i have a very very bad sulfur smell @ my home. i removed my chlorine feeder pump, it don't seem to be working. so i want to purchase new one, i was considering the x030. was wondering a few things, is it self priming ? will the chlorine pump get rid of sulfur smell ? I just bought home few months ago, and its been here whole time, i need to address it ! I also like the chem tech 200 series pump ! Can you give me your opinion please ! Need to get rid of sulfur smell ! I live in Saint Cloud, Fl ! thank you
