To fix the leaky hose you would need to purchase a duct tape, then place the duct tape near the leaky hose.Have one of your friends lower the water pressure in the house (e.g. washing hands, getting a drink, using the toilet or taking shower).Take an adult friend and place them on top of the hose at the back of the house. Your little friend will repair the leaky hose while the water pressure is lowered.
