1. A float apparatus, comprising
a buoyant device having an outer surface with a first end portion, a second end portion and an elongated portion that extends from the first end portion to the second end portion,
the elongated portion of the outer surface having a concaved section that extends from the first end portion to the second end portion, the concaved section defining a shape that has an inner radius between opposite edges and faces an outer radius of a conduit such that with the buoyant device attached to the conduit the concaved section contacts the conduit,
the outer surface of the buoyant device including a convex section opposite the concaved section, and two flat surface sections, each flat surface section extending between a corresponding edge of the convex section to the concaved section, the flat surface sections being angularly offset from one another defining an acute angle therebetween, the convex section including at least one strap receiving recess, and
the buoyant device configured to removably attach to different numbers of identical buoyant devices to radially encircle conduits having different larger outer radiuses than the inner radius of the concaved section by a strap inserted into the respective strap receiving recesses of the buoyant device and the identical buoyant devices which causes the opposite edges of the concaved section to contact the larger outer radiuses with a space between an intermediate portion of the concaved section and the larger outer radiuses.
