I use it for drilling an 8m pipe. The pipe is 2 inches in diameter and it fills it with water. It has gas to regulate how much water it throws. We will see about its durability, but it is quite lightweight for easy transportation. Overall, it does the job perfectly for 120-150 euros.

IN THE END, within a year, the pump's casing got punctured (after three months of use and without going through winter - luckily I fixed it). And now, after winter, it has a gasoline leak and I have to open it to see if it can be fixed. Well, after all this, you can't really call it a reliable machine.

I changed the hose, okay, cost zero, but the casing got punctured again and I will glue it again.

Okay, despite the minor issues, it still works perfectly after two years
