This weekend we took delivery of the water pump, and installed it. Finally we can have functioning garden taps, just as the rainy season starts !
The pump I am using is made by Davey. Its a 1.8kw single phase model. I am also installing a 60 litre Grundfos pressure tank so that the pump does not cycle every time a tap is turned on. The pump will be connected directly to the 50mm ring main pipe, and will service all plumbing on the property (garden, house and workshop). Both water tanks will supply the pump.
Here is the pump an pressure tank:

This is where the pump is going, And here are all the fittings I need to link it all up:

I had just enough room to mount it on a corner of the tank slab, but had to cut away some of the concrete to get the correct angle on the 50mm inlet pipe.

There was a number of times I had to get out the heat gun and soften up the 50mm blueline pipe to get the bend out of it that is caused by it sitting in a roll for so long. Its a real pain in the butt to work with because of this bend.
It took me all day to connect it all up. It was a nervous moment turning it on, but it went OK. I ran around opening garden taps and sprinkler heads to let out the air.
I have to say, it pushed out HEAPS of water. The impact sprinklers shoot for about 15 meters.
