I recently had a customer asked if I could somehow drill a hole under their driveway about 1" in diameter to run a drain pipe through it.....I said I will look into it and get back to them nxt time I come to service their lawn....If i decided to do this what equipment should I use..I will have to rent obviously and also what should I cahrge? is 400 reasonable?

Jetting a pipe through with water requires you dig the trench that allows the pipe to be started and "pumped" through at a level elevation. Futher, the trench on this side needs to be able to accept the water and debris flushing back as it advances.
Patience and well draining soils are helpful. Don't get it stuck. Don't hesitate, to jet a ways, then extract and let the soils drain/flush
ON the destination side, a hole should be dug deep enough that it catches the water and material blown through and can settle into.
Depending on the soils, this isn't tough to go across a twenty foot driveway for a two car garage. If there is some elevation change, and it is sloping away from the driveway, great.
You'll need the 1" PVC, and a good source for water supply. A good volume and high pressure. IF you complain about showerhead pressure in this town- there won't be enough in anything over the sandiest of soils. IF there was hardpan for filling the house pad and slab, it gets tougher.
If the pressure is there, a GHTx3/4" adapter and a 3/4 to 1" bushing will connect the jet rod. JUST DON"T DIG A FIVE DOLLAR HOLE FOR A HUNDRED DOLLAR AN HOUR MAN TO WORK IN....
If the distance is too great and the pipe is suffering from sticktion because the sediment is re-settling in the cavity, you can use air pressure mixed with the water to "boil" it out. This is advanced technique, and if you can't figure it out how to plumb your compressor and jet pipe together, don't try it. If you do, figuring its just plumbing parts, don't blame me your compressor gets ruined from water being forced into it. Your compresor MUST have higher cfm and pressure than the water supply, which is to say you don't own a compressor that large.
OR you could get a 20' stick of steel pipe, and a threaded cap and drive it through with a sledge.
Lets go back to, "What kind of soils do you have to overcome, and what is the distance, and specifically, what is the size of the pipe to be used for drainage, and why/what are you draining? Cause 1" aint much.
Price is hourly, unless you personally have jetted underneath someone else's driveway within ten houses of this.
Driveways, near the garage door slab are the worst place to try and jet pipe through. When the house was being built, the trades people staged and crafted their parts in the garages, and swept the trash to the edge of the slab. The concrete trade comes in after and pours the driveway, and they only pick up the biggest trash and bury the rest, right where you aim to run a pipe. ( The GC has the driveway poured seperate after all construction or else he has a grease and oil stained driveway from every trades crappy ford or chevy leaking all over it during const. )
But then again, maybe I don't know what I'm talking about?GEEVEE®, Pat.Pend. TM, UL

1" drain pipe?

one leaf will stop a one inch drain pipe.Comment

He hasn't replied, but it could be a A/C condensate drain, or a dehumidifier.GEEVEE®, Pat.Pend. TM, UL

I havent went out there and discussed this any further yet....other than he told me its for an irrigation pipe, which obviously makes since!Comment

If your going to run a pipe, you might as well run a 2.5 or 3 inch sleve, run the irrigation line through it and then you would have room for anything else you might need.Comment

Trench The Driveway...........
lay the pipe and be done. might as well do it this way first instead of coming back later and fixing it. :laughing:
