General J-2900

smellslike$tome

I have an opportunity to purchase a used General J-2900 gas powered jetter from another company that bit off more than it could chew and is having to sell off some equipment. I have yet to see it but the General website says it has either an 11hp or 13hp engine and operates at 3000psi with a 4gpm flow rate. It's on a cart with one 150' reel of 3/8" (I think) hose and an additional 150' reel of 1/4" hose with it's own cart, and a variety of nozzles. It supposedly has a rebuilt pump that's less than a year old. The guy wants $700 firm. I'm waiting for a call from the dealer to see what they cost new. Assuming everything is in good working order, how does this deal sound? Is it big enough to power through anything up to and including 3"? Will it take half a day to cut through 4" or will it even do anything with 4"? With the right nozzle will it cut roots? Does anyone own or use this machine? I'm thinking this might be adequate for greasy, ci and galvanized ks drains or any other drain until I get out of the house? Will this just be a bucket of frustration if I expect it to handle 4" sewer service lines?

The pump being rebuilt tells me the engine has plenty of hours. I would be concerned of oil changes and engine wear. I have maintained our equipment for years. The biggest hurdle to be concerned with is the mentality that gas (4 stroke) powered equipment can go way beyond the recommended oil changes than necessary like cars. The "I change oil every three thousand as opposed to every six" ends up being a load of crap. Small engines need constant oil changes, 25-30 hours max. Cutting roots with a jetter is a stretch. Imagine holding that size pressure washer with a concentrated nozzle on a small piece of wood and you would soon realize how much power it actually takes to cut roots. And, not to mention, you are looking at it. AND, the pressure isn't split into three or four holes as a nozzle. High pressure water is not an efficient way of cutting roots. That size jetter in good condition will handle sludge clogs in 4" no problem. Roots will require a mechanical solution.

10-4. I appreciate that info. If it starts easily, doesn't make any funny noises, and doesn't smoke, is it worth $700. I never heard back from the dealer so I still don't know what they cost new.

If it starts easy compression is excellent. Good for you, well worth it.
