Question DetailsAsked on 10/7/2016

who do I call to work on a drain that is blocked under my driveway?

6 years ago we had a spring come up under the slab of our garage. The french drain that was installed was put in and concrete work was done and it worked fine. Now it is not draining and the water is coming out of the drain in front of our garage. We have tried a snake, a power snake rented from Home Depot and also pushing in a pipe to clear whatever is blocking the drain. Nothing has worked. I don't know who to call about this problem.

Sewer Cleaning would be your Search the List category for this. Not Plumbers - because while some do have sewer line cleaning equipment, most do not have long-run equipment or cameras. If they have the equipment, they are likely cross-listed under Sewer Cleaning too.

If DIY does not work, I would have a sewer cleaning contractor come with a jetting tool with a camera to see what the problem is - to jet it out, and simultaneously be able to see if there is a crushed spot or dislocated joint or such and where it is located, if that is the case. Many will bring the camera along if requested (commonly only have one camera for several trucks, so have to request it when you call) and not charge you if it is not needed.

DIY - since you say water is coming out of drain (a surface drain grating I presume) in front of garage, blockage is likely between there and the outlet of the drain pipe downslope somewhere - wherever the spring water has been draining up till now. You might be able to just snake a stiff garden hose with jet nozzle like link below into the outlet of the drain pipe and flush out any debris in there. Once you get through, I would try running other way from drain grating to the outlet as well, to flush it as clean as possible.

Full-length cleanout method - just don't sit one place very long to avoid washing out soil around the french drain (though if properly constructed that should not happen), and try to limit the amount of water that gets in there so you don't flood your garage. You can use as many 10' lengths of threaded PVC pipe as needed (3/4" is what I use) and get a female hose thread swivel fitting for the inlet end to hook your garden hose to, and a fixed male hose adapter for the other end and put on a jet hose nozzle like this link (one with small profile so it does not tend to get caught in there) -

Run the hose in with the nozzle set on a medium wide jet - not a spray, but not a total pinpoint jet either because that can make such a small hole in the debris or muck that it can get stuck. Do it briskly to limit amount of water going in there, and be sure to back all the way out every 3-5 feet of penetration to wash out any debris or sediment you broke free so it does not build up around the jetting pipe and get you stuck in there. Of course, you don't know where the blockage is - but I would say if water is coming out of the drain in front of the garage, the blockage is likely between that drain and the pipe outlet, though would not hurt to take a quick run with the pipe up to the end of the french drain while you are in there.
