Line the ceramic pan with the pond liner. Flatten the liner out, removing all the creases and ensuring the liner fits as well as possible. Trim the portions of the liner that stick out from the pan using the scissors, then trim the liner down so it stops a quarter inch below the rim of the bowl.
Attach the hose pipe to the nozzle on the water pump. Place the pump in the bottom of the ceramic pan with the nozzle pointing toward the back of the pan; or where the back of the water feature will be once it is completed. Put a brick on either side of the pump to hold it in place, with the top of each brick sitting higher than the top of the pump.
Fill the ceramic bowl with water up to the top of the pond liner. Feed the end of the hose through the plastic grille. Place the grille in the bowl on top of the bricks. Drill a hole in the bottom of the the width of the hose. Thread the hose through the hole. Place the two small bowls in the ceramic bowl. Place the urn on top of the bowls. Turn on the pump.
