There are several techniques that are used to clear clogged drains lines. While snaking, rodding and other methods of physically removing obstructions are effective in many situations, the safest and most effective way to clear out stubborn clogs and thoroughly clean out pipes throughout your home’s plumbing system is with a technique called hydrojetting. Over time, pipes inside your home can begin to accumulate limescale, grease and other debris that can gradually slow the flow of waste water, eventually causing drains to empty slowly or backup. Rodding and drain snakes can clear the obstruction, but the usually leave residue that will enable future clogs to form more easily. That’s where hydrojetting provides an advantage.
How Does Hydrojetting Work?
Hydrojetting is a technique that plumbers use to scour the inside surface of pipes with high-pressure water. The process involves inserting a hose to the plumbing system’s cleanout, an access point to the inside of a pipe. The hose is connected to a specialized pressure washer that controls the amount of water that is injected into the pipe.
A plumber must know the right water pressure to use depending on the condition of the pipes, so before beginning a small video camera is used to assess the condition of the interior of the pipe and determine the extent of the buildup so the pressure can be adjusted accordingly. The pressure required to do the job may be 5,000 psi or more, or as much as 20 gallons per minute.
One of the reasons hydrojetting is so effective is that it employs gravity to scour the pipe from the bottom up. The combination of the natural downstream gravity flow of the waste and the upstream pressurized blast of water scours the pipe wall, dislodging debris and flushing it down the pipe. After the pipe has been hydrojetted, the inside of the pipe is again inspected with a camera to ensure that the process was effective.
Even if your drains seem to be working fine right now, hydrojetting of sewer and drain lines is a good way to inspect and maintain your home’s plumbing system to ensure that the small problems don’t become major sewer and drain clogs down the road.
