Horizontal loop settling - refill or not?

    Have a 4 ton Waterfurnace system with a horizontal closed loop installed 2009. After 5+ years the two 377' trenches have settled noticeably - perhaps 6" below grade. Would the effort to move soil around to build up the settled areas be worth it. System works fine, but if this would improve efficiency then I would do it.

    Thank you for all those who offer their opinions.

    It is more a cosmetic choice than anything. Up to you in that regard.

    More cover is always good, but not likely going to add to much unless they are buried shallow to begin with.
