Rhino drains are not injection molded! Injection molding is typically used to mass-produce products for the retail market. Other than mass production, injection molded products are typically designed to use minimal quantities of raw material to produce products in shape and form at the minimum amount of cost which of course allows those products to either be sold cheaply and/or produce high profits.
A bottom drain is the first thing to be installed in your pond, and the last thing that you want to fail! Install a Rhino Drain in your pond with confidence!
