Sewer jetting drain cleaner info chemical Man

Sewer jetting is the process of shooting high powered streams of water through the drain, down into the sewer in order to blast away any debris blocking the passage of water. This is more effective than using a snake, blades, or even drain rods because, first the water is shot at such a high intensity that the force isn't even comparable to manual labour, secondly the water is much more capable of bending around curved or angular pipes to reach all the tight spots.

A sewer jetter is composed of a controlled high-pressure water source such as a pressure washer or reciprocating displacement pump, a flexible high-pressure line (called a jetter hose which connects the high-pressure engine to the mini-reel) of up to hundreds of metres (several hundred feet) in length, the Mini-Reel (a hose reel which can be taken a distance from the engine) and a nozzle that uses hydraulic force to pull the line into sewer drains, clean the sides of pipes, and flush out residue. High-pressure sewer jetters can be mounted on trolleys, inside vans or on trailers. The power of a sewer jetter ranges from 1,000 psi (68 atm) to 5,000 psi (340 atm). Sewer jetter nozzles come in different sizes and applications; a bullet-type nozzle with a streamlined profile can clear a hole for the larger root cutting nozzle. Root-cutter nozzles are designed to cut roots with a spinning nozzle that shoots a jet stream horizontally inside the pipe. High pressure sewer jetters with root-cutting nozzles can clear a hole through the center of a root-infested sewer line and with its rear-facing jet streams cut the roots and clean the pipe walls, flushing the root debris through the sewer line. The sewer jetter has been labeled as a technological advancement of the plumber's snake (also known as an electric eel) drain clearing method.[citation needed]

 sewer jetters and pressure washer sewer jetter attachments are primarily used by service personnel and homeowners to remove soft obstructions throughout the length of a building's sewer drain and to prevent the recurrence of clogs by cleaning the sides of drain pipes and flushing out residue. Pressure washer sewer jetter attachments are generally lower in cost and weight than electric drain cleaners with an equivalent reach, and can present a lower risk of scratching plumbing fixtures.

Truck and trailer-mounted sewer jetters used by municipalities and larger service companies benefit from the high hydraulic horsepower delivered by powerful displacement pumps and so can remove tree roots and other solid obstructions.

Advantages of sewer jetters include the relative ease of penetrating long sewer lines and the ability to remove residue that accumulates along the sides of sewer pipes, thereby reducing the need for subsequent drain cleaning.

Disadvantages of pressure washer sewer jetter attachments and many portable jetters include an inability to extract tree roots and other hard obstructions. Disadvantages of truck- and trailer-mounted sewer jetters include high relative cost and weight, and the requirement for extensive training to comply with manufacturers' safety guidelines.

Safety considerations for sewer jetters include a requirement to wear protective gloves and eye protection, to avoid contact with sewer drain fluids, and to ensure that the jetter nozzle operates only inside the sewer pipe. Furthermore, larger truck- and trailer-mounted units that operate with sufficient power to cut tree roots require extensive training and strict adherence to manufacturers' safety guidelines to avoid serious injury.
