*Product Change Notification*
Product- All Executive Wet Ends and Pumps
In order to accommodate for the growing demand of wet ends and pumps, Waterway will be removing two of the three drain plugs located on the front of the wet end. The two side ports are rarely used. For those instances where they’re required, the drain plug ports can still be drilled and tapped on location. This change will be introduced as a running change starting immediately. If you have any questions regarding this notification, please contact a technician or customer service representative to assist you.

**Pump & motor manufacturers reserve the right to change motors on pumps or style of motor without notice. Motors shown may differ from current stocked product. Functionality remains the same**
