Bypassing the backflow preventer may be desirable in situations where water supply pressure is low.

Remove the 1″ white spa hoses from the shutoff valves immediately downstream from the backflow preventer by uncoupling the camlock fittings.
Attach the loose ends of the hoses to the ends of the bypass adapter.

Move the stack of adapters from the injection system inlet to the inlet of the bypass adapter and attach the water supply line.

The stack of fittings allows attachment with 1-1/2″ female camlock, 1″ female camlock, 3/4″ female camlock, or 3/4″ male garden hose.

Note that the bypass adapter has shutoff valves for each Dosmatic pump. You may want to provide your own shut-off valve at the end of the water supply line if you will be moving the injection skid from place to place on the site. This is especially true if the water source is remote from the injection skid.
