I received estimates on getting an irrigation system installed in my back yard. The majority of the cost is for digging down to the house's line in the front of the house (4 feet deep), splitting the water line, adding a backflow preventer, tunneling under my walk, trenching all the way along the side of the house at a depth of 2 feet, and then installing a drip system.
Today I was in my basement looking a where my water main comes into the basement, and am curious if there's a reason why they can't just split off the main where it enters inside my basement, route the main along the ceiling of my basement, and then out into the backyard through the basement wall?
Is there a reason this is not a good idea? Would love to save the time/trouble of digging all those trenches if there's no serious downside to going through my basement.
