Direct Fill Links
The direct fill link is the most popular filling device because it is so easy to use.
Depending on water quality, the direct fill link can be connected to a standard garden hose, a deionizer, an 8 gallon Aqua Sub Jr. cart or 25 gallon Aqua Sub cart to put water directly into the batteries. The direct fill link has a built-in flow indicator and pressure regulator, reducing pressure down to 10 PSI. It can handle up to 90 PSI from the water source. Water sources with greater pressure should use a brass pressure regulator to reduce incoming pressure.
The direct fill link is not recommended for use with Philadelphia Scientific® injector systems or Watermaster® systems.
