[Our drainfield] used to have some low spots where when we took a shower and did some loads of laundry, you could see the water out in the drain field. But since [Ken} came and did the EarthBuster, it doesn't do that anymore. With EarthBuster, you've got nothing to lose. If you're having trouble with your septic, you've either gotta replace the drain field or try this--and if it works, it's better to try and fail than to not try at all.
