Remove the drain screen usually one screw in the middle. push a garden hose as us mentioned into the drain as as far as you can. Hard pack a wet rag around the hose so the water can only go down the drain. while holding the hose have someone turn it on easy then full blast. Water will blow blockage into tank. Make sure there is room in the tank for the water
