9. A drain fixture installation system for facilitating connection of a drain fixture to a drain pipe, the drain fixture including a fixture head at an upper end thereof and a lower, exteriorly threaded fixture stem with a bore extending therethrough, the fixture head projecting radially outward from the fixture stem, the drain pipe presenting a free end below the intended surface level of a concrete slab, said system comprising:
-
a) a fixture receiver comprising; i) a pipe connection adaptor having an adaptor bore extending centrally therethrough and sized for securement to the free end of the drain pipe such that said central adaptor bore extends in communication with the drain pipe; and ii a coring sleeve comprising a fixture head receiving bowl projecting outward from a coring sleeve stem having a central coring sleeve bore extending therethrough and wherein said fixture head receiving bowl opens centrally into said coring sleeve bore;
said coring sleeve stem is threadingly coupled to said pipe connection adaptor such that a level of an upper edge of said fixture head receiving bowl may be adjusted by rotating said coring sleeve relative to said pipe connection adaptor;
said coring sleeve having an internal coring sleeve thread formed along said coring sleeve bore and below said fixture head receiving bowl;
said fixture head receiving bowl sized to receive the fixture head therein with the lower, exteriorly threaded fixture stem extending into said coring sleeve bore and threadingly coupled to said internal coring sleeve thread;b) a plug having a cylindrical, plug stem with an external thread and a plug head projecting radially outward from said plug stem at an upper end thereof, said plug head sized to extend substantially across said fixture head receiving bowl when said plug stem is threadingly connected to said internal, coring sleeve thread formed in said coring sleeve bore; and
wherein;c) when said fixture receiver is connected to the drain pipe and said plug stem is threadingly connected to said coring sleeve, concrete may be poured around the drain pipe and finished to a level even with an uppermost extremity of said drain fixture installation system and said plug acts in combination with said fixture head receiving bowl to produce a void in the concrete into which the fixture head can be inserted once the concrete has hardened and said plug is removed from said fixture head receiving bowl. - View Dependent Claims (10, 11, 12, 13, 14, 15, 27)

16. A method of installing a utility access fixture on conduit in a slab of poured material, the utility access fixture having an externally threaded cylindrical stem and a head projecting radially outward from an upper end of the stem, the method comprising the steps of:
-
a) connecting a coring sleeve to said conduit, the coring sleeve having a bowl formed at an upper end thereof and projecting radially outward from a lower, internally threaded coring sleeve stem, the bowl defining a bowl cavity communicating with a through bore extending through the lower internally threaded coring sleeve stem;
said bowl cavity sized to receive a head of the utility access fixture when the stem of the utility access fixture is threaded into the lower, internally threaded coring sleeve stem;b) installing a plug in the coring sleeve wherein the plug is sized such that an upper surface of the plug extends generally flush with an upper edge of the bowl and the plug head covers the bowl cavity; c) adjusting the position of the coring sleeve relative to the conduit until an upper surface of the plug is at a level to which the concrete is to be poured; d) pouring the poured material around said conduit e) finishing the poured material to a level generally flush with said upper surface of the plug to form the slab, the bowl and the plug acting in combination to form a void in the poured material; f) allowing the poured material to harden; g) removing the plug to provide access to the void in the poured material; and h) threading a utility access fixture into the coring sleeve such that a head of the utility access fixture is received in the bowl cavity with an upper surface of the utility access fixture extending generally flush with an upper edge of the coring sleeve bowl. - View Dependent Claims (17, 18)

19. A drain fixture installation system for facilitating connection of a drain fixture to a drain pipe, the drain fixture including a fixture head and an externally threaded fixture stem with a fixture bore extending therethrough, the fixture head projecting radially outward from the fixture stem, the drain pipe presenting a free end below the intended surface level of a poured slab, said system comprising:
- a coring sleeve having a coring sleeve stem connectable in fluid communication with the drain pipe and a bowl projecting outward from said coring sleeve stem, said bowl defining a bowl cavity surrounding and opening into a coring sleeve bore extending through said coring sleeve stem;
said coring sleeve stem having an internal thread formed therein below said bowl cavity;
said bowl cavity sized to receive the fixture head therein with the fixture stem threadingly coupled to and within said coring sleeve stem; and
a plug removably positionable in said bowl cavity, prior to reception of the fixture head therein, to extend across said bowl cavity without extending above the intended surface level of the poured slab;
wherein the drain fixture is threadingly couplable to said coring sleeve after removal of said plug from said bowl cavity. - View Dependent Claims (20, 21, 28)

22. A method of installing a utility access fixture on an upwardly extending conduit in a concrete slab, the utility access fixture having a stem and a head projecting radially outward from an upper end of the stem, the method comprising the steps of:
-
a) connecting a coring sleeve to said conduit, the coring sleeve having a bowl formed at an upper end thereof and projecting radially outward from a lower portion thereof, the bowl defining a bowl cavity communicating with a through bore extending through the lower portion of said coring sleeve;
said bowl cavity sized to receive a head of the utility access fixture when the stem of the fixture is inserted into the lower portion of the coring sleeve;b) installing a plug in the coring sleeve wherein the plug is sized such that an upper surface of the plug extends generally flush with an upper edge of the bowl and the plug covers the bowl cavity; c) pouring concrete around said conduit d) finishing the concrete to a level generally flush with said upper surface of the plug to form the slab; e) allowing the concrete to harden; f) removing the plug to provide access to the bowl cavity; and g) positioning a utility access fixture in the coring sleeve such that a head of the fixture is received in the coring sleeve bowl cavity and the stem of the fixture is coupled to the lower portion of the coring sleeve. - View Dependent Claims (23, 24)
