Are you the DIY type?
These delivery panels are pretty sweet. They are made from a lightweight aluminum and easily mount to many different surfaces.
They include the RHG delivery pump with digital flow controller and on/off Remote control.
The pump will siphon your pure water holding tank and deliver the water via a hose (not included) to your water-fed pole.
The digital flow controller allows you to turn up or down the flow/pressure of your pump based on your specific job. This in turn allows you to conserve your pure water supply for the day.
The remote has multiple functions built in including the ability to turn up, down, and off the flow of water.
Simply hook the inlet side of the pump up to a short hose that siphons your tank and the outlet side of the pump to a hose/reel that feeds your water-fed pole.
The only other thing you need is a 12 volt battery to supply this power.
