Answer: Can I Use Vinegar to Flush My Water Heater?
Yes — white vinegar can be used to dissolve sediment and mineral buildup in water heaters. For tank models, add 1-2 gallons of white vinegar through the anode rod opening or the T&P valve opening, let it sit for 6-8 hours, then flush. For tankless models, circulate a vinegar solution through the service ports using a pump. Vinegar is food-safe and effective.
