1. A method of anchoring a riser section in concrete using a form, the method comprising the steps of: providing a mounting bracket and securing said bracket to a form wall inside the form; placing a riser section into the form wall around said mounting bracket; providing a riser cover with at least one post extending below said cover; positioning said riser cover on said riser section; securing said at least one post of said riser cover to said mounting bracket; pouring concrete into the form around said riser section, permitting said concrete to harden; and thereafter removing said riser cover from said riser section and from said mounting bracket. 2. A method of anchoring a riser section in concrete as claimed in claim 1 wherein said bracket includes a planar surface having at least one aperture formed thereon, said planar surface defining tapered sides about said aperture to define a gripping web to frictionally receive said at least one post of said riser cover, the steps further comprising frictionally engaging said at least one post with said gripping web. 3. A method of anchoring a riser section in concrete as claimed in claim 1 wherein said riser section includes a sidewall having a detachable anchor tab attached thereto and extending outwardly therefrom, the steps further comprising surrounding said anchor tab with concrete when pouring said concrete into said form. 4. A method of anchoring a riser section in concrete as claimed in claim 2 wherein said cover includes two posts extending below said cover, said bracket includes at least two apertures formed thereon defining tapered sides about said apertures to define a gripping web at each said aperture, the steps further comprising frictionally engaging each said post of said cover with said gripping webs of said bracket. 5. A method of anchoring a riser section in concrete as claimed in claim 3 wherein said cover includes two posts extending below said cover, said bracket includes at least two apertures formed thereon defining tapered sides about said apertures to define a gripping web at each said aperture, the steps further comprising frictionally engaging each said post of said cover with said gripping webs of said bracket.
