Every RVer needs one of these for water heater maintenance
Another option is to just use 5' of cheap clear plastic hose. With water heater full, pump off, open a faucet to bleed off pressure. This leaves the water heater full, but zero pressure.
Remove the anode/drain plug, insert one end of the hose, suck on the other end to start a siphon. Move the tank end around to "vacuum" the bottom of the tank. Since the hose is clear, easy to tell if you have all the sediment out. If really bad, may have to turn on pump, refill and repeat.
