Always shut off the power (for electric) or gas supply (for gas) to the water heater *before* starting any work to prevent electric shock or gas leaks. Also, ensure the cold water supply is off to prevent unexpected hot water flow and potential scalding. Wear appropriate safety gear like gloves, especially when handling hot water or parts.

No, the core process primarily requires a standard garden hose for draining and a screwdriver for tasks like opening the drain valve or accessing panels. However, using a hot water-rated hose is highly recommended for safety, and welding gloves can protect your hands from hot water or tank surfaces during the process.

Using a hot water-rated hose, like the 'Element MAXLite Hot Water Rubber+ Hose' mentioned, is crucial because the water draining from the tank will be very hot. A regular garden hose can be damaged, melt, or even burst under high heat and pressure, leading to burns, property damage, or a messy situation.

If popping persists, there might be significant, compacted sediment that a single flush couldn't fully remove, or the issue could stem from a faulty heating element or burner. Weak water flow after flushing often indicates that sediment has clogged the drain valve or aerators in your faucets; check and clean those if necessary.
