Jetter Hose Fitting And Safety Guide

 

NP Jetter Hose Group

A jetter hose is typically found on a sewer jetter – also called a water jetter, jetting machine, jet rodder, flush truck, and sewer cleaner. The ½ inch to 1 inch diameter hose is mounted on a high-pressure water pump.

It may have a water spray nozzle attached to clean sewer pipes. The sewer nozzle head is available in a variety of designs from pure cleaning heads to rotating cutting heads for roots in sewer line. The sewer cleaner heads have rear facing water spray jets that self-propel the hose and also flushes back debris to the manhole for catch basin cleaning.

 

 

What length of jetter hose reel?

 

Jetter Hose Reel

A sewer jetter machine can be fitted with a hose length of up to 800 feet. A pressure drop occurs as the hose gets longer as a result of friction on the inside wall of the hose. For example a 2400 psi pump at 70 gallons per minute to 400 feet long with a 1 inch hose can lose up to 1 psi per foot resulting in only 2000 PSI at the nozzle.

 

 

What’s the best diameter hose?

Because of the difficulty of handling jetting hoses, manufacturers design high-pressure, low volume pump with three-quarter inch hoses, however there is a loss of pressure at 40 gallons per minute, that is 2 PSI per foot.

 

Fitting sewer nozzle with sewer jetter

The size of sewer jetter, be it a small back trailer, or a large combination sewer cleaner, will mandate the correct nozzle size. Sewer nozzles are specific to the hose - that is a three-quarter inch nozzle must fit a three-quarter inch hose.

 

Hose safety

Sewer pipe cleaning contractors have to maintain scheduled inspection, repair, maintenance and installation of important components. The high-pressure hose has to be regularly inspected for abrasions, nicks, cuts to avoid catastrophic hose failure and serious consequences such as injury or death.

Safety checklist

 

Jetter Hose Jedi PoseOH, you said Jetter Hose, not Jedi Pose!

Verify pressure rating and couplings and fittings

 

  • Prior to operating the hose, visually inspect assemblies, size selected and pressure rating.
  • Check for bulging, cuts, twists, flat spots, kinking, corroded or broken wires.
  • Sewer jetting nozzles should be inspected for cleanliness, unobstructed outlets and damage.


A tiger tail is a larger hose that is placed over the jetter hose and it is placed into the manhole. The tiger tail helps direct the hose assembly and also prevents wear and tear.
