Find well/bore depth and static water level.....

To find the depth of a bore/well, lower a weight on a LIGHT string into the bore/well until you feel it hit the bottom. Then mark the string at the top of the well, pull it out and measure the length of the string that was down the well/bore. NOTE. You need to use a light string in deep bores/wells (light fishing line may be good). If the string is too heavy and the weight too light, the weight of the actual string can make it difficult to feel when you hit the bottom .

To find the static water level, lower a small bottle (with a little sand or gravel in it to give it weight if it is a plastic bottle) into the bore/well on the end of a LIGHT string until you feel it hit the water surface. Then mark the string at the top of the bore/well, pull it out and measure the length of the string that was down the well/bore.

Keep it clean

The following is useful for ANY air lines, but if you are using the L2 or S2 pump WITH a controller, it is important to ensure that the air lines are clean before connecting and commissioning the unit. If any debris is present it can end up in the flow switches and solenoid valves in the controller and jam them up, so the controller is unable to operate correctly.
The way to ensure clean lines is 2-fold:
1) keep the ends of the air lines capped or plugged while working with them to keep any dirt and debris out.
2) when lines are laid out, connect to the compressor, but leave open at the controller end, run the compressor until it shuts down and then open the air supply valve right up. That will give a hard blast of air if the compressor has a tank and should blast any loose particles out the open end. Do that a few times until the line is clean and no more debris comes out.
Once clean, connect up the controller and start pumping....

If installing the Brumby pump in a bore or well, the piping needs to be secured at the top to the bore/well casing for 2 reasons:
- if the bore/well is deep, the pump may bury itself in the mud in the bottom and you won't get any water up as a result. The pump should be set just off the bottom, but not so deep that the compressor doesn't have the power to lift the water.
- if the water is deep (the pump is submersed a long way) - once you apply air, the pump will tend to become buoyant and rise, so you may have a great length of piping rising out of the hole after you start the compressor.
This is of course a great thing if you should ever want to remove the pump....the hard lifting is done for you...

If the pump is used in an open water body or large well, it may need to be weighed down to keep it reasonably vertical.
