Yes, flushing your water heater can indirectly improve hot water pressure and flow if your tank has accumulated heavy layers of mineral sediment, calcium scale, or sand at the bottom. Over time, thick sediment buildup restricts the internal flow of water through the tank and can even plug the hot water outlet dip tube. By draining and flushing the tank annually, you clear out these obstructions, restore efficient heat transfer, and ensure unobstructed hot water delivery to your fixtures. Verification: Test hot water flow at your nearest bathroom sink after completing a full tank flush to confirm steady pressure.
