Yes, you can replace a water heater heating element without fully draining the tank — most homeowners only need to drain it partway (below the element) rather than empty it completely. This makes hot water element replacement and water heater element removal more manageable, but the process can be tricky and is best left to a professional plumber. If the heating element is not properly removed and reinstalled, it can cause leaks or damage the tank.
Some elements corrode in place, so if you cannot remove the heating element from your water heater using a standard element wrench, don’t force it — a professional has the tools (including impact wrenches and penetrating solutions) to safely replace water heater elements without stripping the fitting or cracking the tank.
At The 5 Star Plumbing, our licensed technicians know how to change a heating element in a water heater — gas or electric — quickly and safely, whether you need a single element replaced or want to replace water heating elements as part of routine maintenance.
