With the ,How would you guys get the pipe under the driveway?
It kind of depends on if it's a bitchumen driveway ,concrete drive ,single drive ,double drive and the type of material that needs to be removed and then how much you want to spend.
The pressure washer idea I can see as being messy and not very successful if you have rock to get through.
If you have a single drive, a 2 stroke or hand post hole digger (auger) may be used from both sides to join up in the middle.
If it's a double driveway it may just be a lot cheaper and easier to get a angle grinder and cut out a foot of the drive and dig the trench ,then re cement or re tar or even put a line of bricks as a pattern in the middle of the drive.
Mostly in my area when people have to put a pipe under the foot path or drive they just cut a section out with the grinder then re cement after the pipe goes in as the cost in drilling wouldn't be worth it.
"Next week, going to speak with the sparky who has done a fair bit of electric work for us (as he will be doing the wire up and start relay) to work out what gauge wire I need to run about 35m from meterbox to bore."
"Any preliminary thoughts on wire gauge for those of you who are electrically minded (1.1kw pump)"
The length of the wire does not have a direct impact on amperage, but it does have an effect on voltage through resistance. The longer the wire, the higher is cable resistance and voltage drop.
You need to know the Amperage draw on the 1.1kw pump ,I think it's around 8.5 amps
There are voltage drop calculators online to check.
