clogged main drain line?

[SewerRatz]

Well, I'm sold.
What kind of PSI does it take to make water do this to a chicken?
Will these jets amputate fingers?
Cut small tree roots?

Jetters can cut you, but the fact it is injection of water under your skin is worse. I have three jetters. A small electric unit for sink lines and basic flushing, runs 1200 PSI at 2.2 GPM A 3000 PSI at 5 GPM and the other machine which uses the same nozzle as the chicken sandwich one is 1700 PSI at 18 GPM. They make units that go as high as 5000 PSI @ 12 GPM to 3000 PSI at 120 GPM. The GPM helps flush the line as the pressure breaks up the blockage. More GPM is needed in larger pipes to properly flush them out. To large of a jetter will take pipes apart.

Our's does 4,000 PSI. @ 18 GPM

Yes it will cut roots.
And we're not going to let it touch my skin...

injection of water under your skin is worse.

I got a book on hand injuries after my left hand lost a fight with a table saw blade, and in the book they talked about people getting paint under high pressure injected into the hand.
Pretty grim.

Power steering pump pressure can go to 4000 PSI and the auto books warn about this, too. Imagine getting that fluid in your eye? Yuck.

That chicken-pulverizing video is sumpin' else.
We're talking some real horsepower here.

Maybe 5 hp to get these pressures and flow rates? Dunno'.

Never mind -
4 GPM / 3200 PSI, 10 HP

[kingsotall]

Spartan or Gorlitz needs to make a Hemi.

[Thatguy]

And the water comes out at 600'/sec, about half the speed of a pistol bullet.

Ours is 50 HP. Click Here

How about descale a pipe?

What kind of pipes are there besides "plastic, metal or ductile iron pipes"?

How many kilobucks for one of these water jet trailers?

With this pressure and flow rate through a long skinny hose I'm not sure how much of the 50 hp actually gets delivered to the task.

These tools are dangerous. . . Spinning tools can make for degloving injuries and Google Images has plenty of photos of this particular kind of accident.
