An accessory for use in construction includes a conduit ( 12 ) that has an inlet end ( 34 ) portion and an outlet end ( 18 ) portion. The outlet end ( 18 ) portion is mountable on a drainage pipe ( 22 ) so that the conduit ( 12 ) and the drainage pipe ( 22 ) are in fluid communication with each other. A removable closure member ( 40 ) is mounted on the inlet end ( 34 ) portion to close the conduit ( 12 ) when not in use or during building construction, so that ingress of material or detritus into the drainage pipe ( 22 ) is inhibited.

1. An accessory for use in construction, and mountable on a drainage pipe extending above a substrate, the accessory comprising:a conduit that has an inlet end portion and an outlet end portion, the outlet end portion being mountable on a drainage pipe so that the conduit and the drainage pipe are in fluid communication with each other, the inlet end portion having an enlarged diameter to define a shoulder at a junction of the inlet and outlet portions so that, when the outlet end portion is mounted on the drainage pipe, the shoulder bears against said substrate, a length of the inlet portion corresponding to a thickness of a screed layer to be formed on the substrate such that the inlet end portion defines a reference level arrangement for the screed layer; anda removable closure member which is mounted on the inlet end portion to close the conduit when not in use so that the ingress of detritus into the drainage pipe is inhibited, the inlet end portion and the removable closure member being configured so that, when the closure member is removed, a grate member can be fitted in the resultant opening. 2. An accessory as claimed in claim 1, in which the removable closure is connected to the inlet end portion by a zone of weakness to facilitate separation of the closure from the inlet end portion. 3. An accessory as claimed in claim 1, in which end portion has a plurality of openings defined therein to permit drainage of excess water collected about the inlet end portion. 4. An accessory as claimed in claim 1, which includes a grate member that is received in the inlet end portion, once the closure has been removed. 5. An accessory as claimed in claim 4, in which the grate member is an assembly of a grate frame and a grate element. 6. An accessory as claimed in claim 5, in which the grate frame defines an inwardly extending lip on which the grate element is supported, while the grate element defines a shoulder that bears against the lip of the grate frame. 7. The accessory as claimed in claim 1, which is of a plastics material. 8. The accessory as claimed in claim 1, which includes a sealing member having a flange portion and a body portion, the body portion defining a passage in which the conduit is received and the flange portion being positioned to extend radially from the conduit when the conduit is received in the passage, the conduit and the body portion being attachable to a drain pipe positioned in a substructure, with the flange portion overlying an upper surface of the substructure. 9. An accessory as claimed in claim 8, in which the sealing member is of a suitable sealing material such as an elastomeric material. 10. A drainage kit, mountable on a drainage pipe extending above substrate, the kit comprising:a conduit that has an inlet end portion and an outlet end portion, the outlet end portion being mountable on a drainage pipe so that the conduit and the drainage pipe are in fluid communication with each other, the inlet end portion having an enlarged diameter to define a shoulder at a junction of the inlet and outlet portions so that, when the outlet end portion is mounted within the drainage pipe, the shoulder bears against said substrate, a length of the inlet portion corresponding to a thickness of a screed layer to be formed on the substrate such that the inlet end portion defines a reference level arrangement for the screed layer;a removable closure member which is mounted on the inlet end portion to close the conduit when not in use so that the ingress of detritus into the drainage pipe is inhibited the inlet end portion and the removable closure member being configured so that, when the closure member is removed, a grate member can be fitted in the resultant opening; anda sealing member having a flange portion and a body portion that defines a passage, the conduit being mountable on the body portion so that the outlet end of the conduit and the passage are in fluid communication with each other. 11. A metho d of construction comprising:mounting a conduit on a drainage pipe extending above a substrate, the conduit having an inlet end portion and an outlet end portion so that the conduit and the drainage pipe are in fluid communication with each other, the inlet end portion having an enlarged diameter to define a shoulder at a junction of the inlet and outlet portions so that, when the outlet end portion is mounted on the drainage pipe, the shoulder bears against said substrate, a length of the inlet portion corresponding to a thickness of a screed layer to be formed on the substrate such that the inlet end portion defines a reference level arrangement for the screed layer, the inlet end portion having a removable closure member to close the conduit when not in use so that the ingress of detritus into the drainage pipe is inhibited, the inlet end portion and the removable closure member being configured so that, when the closure member is removed, a grate member can be fitted in the resultant opening;removing the closure member; andpositioning a grate member in the inlet end portion, once the closure member has been removed.
