The drain plug is a small plastic element located on the bottom of the pre-filter body of the Mr.Pump ECO pump. It allows manual draining of residual water from the pre-filter chamber before winterizing the pool, thereby protecting the pump from frost damage.
The plug is made of chemically resistant plastic with a sealing ring that prevents water from seeping during operation. The simple threaded or rotary design allows draining even without tools.
In case of loss or damage to the plug, immediate replacement is necessary – operating the pump without the plug will cause water to leak from the pre-filter. The original replacement plug guarantees the correct dimensions and sealing for trouble-free operation.
