Plastic stock tanks are inexpensive and durable items to hold large amounts of water for livestock. Larger tanks will supply drinking water for longer periods and have the added benefit of having to be filled less often. After several years, plastic stock tanks may develop cracks from changes in weather conditions or from drying in the sun. The best place for a stock tank is in a shady area so it is not in the sun all day. Stock tanks also can crack if they are full to the top and the water freezes overnight, expanding in the tank.

Empty any remaining water out of the stock tank by turning the tank over. For large tanks dip water out of the tank with a bucket so that the water level is six inches below the bottom of the crack.
Sand the area of the crack on the outside of the stock tank with medium-grit sandpaper. Rub the immediate crack area and about one-quarter inch on each side of the crack. This will roughen an area for the other materials to adhere to on the tank.
Cut a piece of fibreglass cloth to fit over the entire crack and in a size about 1/4-inch wider than the crack. Put the fibreglass cloth on the tank covering the crack.
Mix the epoxy according to package directions. The two separate products mix together to form a firm-bonding agent. Place the epoxy on a paper plate or other disposable item.
Brush the epoxy onto the fibreglass cloth with a small paintbrush. Cover the entire surface of the fibreglass cloth by brushing side to side from top to bottom. Let the epoxy dry for 20 minutes to harden.
Refill the tank with fresh water. Applying the epoxy on the outside of the water tank will not harm the water drunk by the livestock.
Tips and warnings
- Auto parts stores sell plastic tank-repair kits that include all of the supplies necessary to seal a crack on any plastic item. Long cracks may require purchasing several repair kits to seal the entire crack.
- Make sure to let the epoxy set for 20 minutes so that it is entirely cured before adding water to the tank. Rushing the process may result in a defective repair.
