Global Water Solutions now guarantees the freshest water quality possible with the revolutionary Flow-Thru™ series design, available in both composite and steel models. All Flow-Thru tanks feature GWS’s exclusive patented Flow-Thru technology which assures that your system will provide the freshest water quality possible by simply eliminating stagnation!

The Flow-Thru connection diverts system water into, and more importantly out of the tank. Flow-Thru will work with pumped supply or direct connection to the water supply without any pump. This constant flushing action assures that the water in the tank remains as fresh as possible and eliminates the possibility of stagnant water during normal system operation.

Applications include


  • Commercial water suply systems
  • VFD/VSD controlled pressure boosting system
  • Heating, ventilation, and air conditioning
  • Swimming pool and spas
  • Wet cooling towers
  • Evaporative cooling

Both our steel and composite Flow-Thru tanks incorporate our proven patented controlled action diaphragm (CAD-2). CAD-2’s steel clench ring regulates movement and prevents the diaphragm from rubbing against the tank wall.Flow-Thru is also the ideal solution for constant pressure water system installers seeking to store water without the risk of stagnation.

Flow-Thru tanks are quality tested at several stages on the production line to ensure the structural integrity of every tank. Flow-Thru tanks represent the best value for the investment and are the best quality anti-stagnation tanks available today.
