Pipe dropoff stump
A pipe dropoff stump is a piece of material that is placed under a waterfall or flowing pipe to prevent the surface beneath it from eroding. The material used is normally made out of a solid material like Concrete or Cement as it must be put under extreme stress for long periods of time without maintenance.
Uses for a Pipe dropoff stump assist drainage and is used to prevent the formation of a Plunge pool.
Wear
A concrete dropoff stump with thick walls will last hundreds of years depending on the amount of flow and depending on the type of concrete. [1]
Physical characteristics
A dropoff stump is normally a solid concrete stump weighing around 280 pounds (127kg) and does not contain rebar as it will rust, chip and reduce the lifespan of the stump.
Setup
A dropoff stump should have its pipe tested under average and extreme conditions to calculate where the stump should be located. It is normal for the stump to be placed under the flow of the pipe and customised in height/width/thickness depending on where the water hits the floor.
Uses
A dropoff stump is designed to protect and prevent a floor or surface from erosion. It is particularly placed on concrete structures. Sometimes due to their uses it is recommended to stick them to the floor using bolts.
