We picked up our new trailer jet on Thursday afternoon and it went right to work on Friday morning. The jet is made by Sewer Equipment company of America. It is 18gpm @ 4000 psi, it has a 51hp Cat diesel engine, full control wireless remote control, flow control to adjust the pressure from 0-4000psi(This is nice to have since its first job was 6 inch orangeburg and we did not want to destroy the pipe just clean it) pulsation control to navigate 90s or tough blockages, 300 gallon water tank, air purge & cold weather recirc for winter use, 500 feet 1/2 inch hose, rotating hose reel and electric brakes. This jet is really designed right with a full tank of water, you don't even know your towing it, the balance is right on. Thanks to Tom Doheny and everyone at Jack Doheny Supply.
