: Is this a real question, or an ad for web sites? Many people will just close the window rather than scroll all the way through the "spam" to get to this answer box. A two wire pump is usually self contained and may or may not be a capacitor start model. The three wire units usually have the capacitor in the "Frankling control box" where it can be tested and replaced in case of failure. If the two wire pump is a split phase rather than capacitor start, it will have less starting torque and will thus be easier to jam, not harder.

The hardware store guy says 2 wire pumps are ok for residential use on a 10 gpm 1/2 or 3/4 hp pump. He says that they dont need a franklin "control unit" (not sure of term) and they also are good for anti clog because they will reverse direction momentarily when going getts tough and kind of breakup a potential sand or grit clog. Assuming this is essentially correct why would one want a three wire pump which has the same ratings and costs more for the extra unit and needs extra wiring hassle and a dry place to install ( which I will have as I plan to put pressure tank next to pump on a concrete pad with a suitable shelter. ) What are the pros and cons between the 2 and 3 wire setups? Any advice would be appreciated. Info: static water level is 43 ft. about 2 feet climb and 80 ft to house Thank in advance , Smokey Follow Ups:
