High-pressure water jetting is recognised as one of the most versatile and efficient methods of clearing a blockage or cleaning a pipe or drain but selecting the right equipment is vital.
The average small trailer unit or van pack works at a pressure of 3000 to 4000 lbs psi with a water flow rate of 10 to 15 GPM. This is suitable for most domestic and normal commercial operations in 100 and 150mm diameter pipes. For specialised works, the pressure can rise to 30,000 lbs psi for cutting operations and the flow rate to well over 100 GPM, for heavy silt removal in large diameter drains.
From this alone it is clear that there is more to this than just turning on a tap!
In our fleet we have the usual diesel van packs and LPG for noise sensitive areas in our general service vehicles. These units are ideal for the majority of the everyday blockade clearance work we come across and with the addition of specialist tools they can be used for root cutting or heavy intensive cleaning far beyond what they could achieve even a few years ago.
These van pack machines are perfect for what they were designed but can occasionally be restricted due to the lack of onboard water as they only have small header tanks or the diameter of the pipe. When this is a concern we turn to tanker jetters that carry water. These can operate at the same performance as the van packs so still making them ideal for everyday use but with minor adjustment they can perform at far higher flows and pressures eg 34gpm at upto 8000 lbs psi making them so much more!
Also in our fleet we have jet/vac vehicle performing at 2200 lbs psi at 54 gpm for those larger diameter drain and pipes.
