Neither, you want plain 95/5 Tin Antinomy solder for domestic water service. Both of the other two are for electronic uses. I also use silver bearing solder for HVAC refrigeration tubing.
Use Oatey #5 paste and don't use a POS hardware torch. Use a Turbo Torch with 1lb Mapp canisters. Cost about $45 bucks and it will be the best money you ever spent.
FYI.. Do NOT use acid core for ANYTHING electrical. The acid in the flux attacks the soldered joint over time and causes electrical probs that will have you so frustrated you'll be ready to push the car off a cliff.
The solder the guy at the hardware store just didn't look right when I used it that's why the questions. I marched right down to the local plumbing supply hose for the 95/5 solder and the correct paste. Big difference. Thank you again. Drew
For plumbing 50/50 but 95/5 and/or silver solder is the best. Make sure you emery cloth or clean the surface well, some soldering paste and you are good to go. Rosin core for electrical connections. Not sure what acid core is used for , but in my 15 years in the hardware business, hardly sold acid core.
