A washing machine outlet box includes a housing having a bottom wall containing multiple openings and two valve mount inserts insertable into selective openings for supporting water shut off valves therein. The two valve mount inserts may be individual valve mount inserts that are separately insertable into two of the openings or the two valve mount inserts may be joined together for insertion into at least one of the openings as a unit. A drain pipe may be connected to another opening in which the two valve mount inserts are not inserted. A twist on and twist off test cap may be used to seal off the drain pipe opening during pressure testing of a sanitary drainage system to which the drain pipe is connected.

What is claimed is: 1. A washing machine outlet box comprising a housing having a bottom wall containing multiple openings, two valve mount inserts joined together in spaced relation, the two valve mount inserts being selectively axially insertable into different openings as a unit to provide valve mounts for hot and cold water shut off valves, and snap lock connections on the two valve mount inserts for selectively securing the two joined valve mount inserts in the different openings as a unit during axial insertion of the two joined valve mount inserts into the different openings. 2. The box of claim 1 further comprising a test cap that is insertable into an other of the openings, the test cap including a seal for sealing off the other opening during turning of the test cap in a tightening direction after inserting the test cap into the other opening, and the test cap being turnable in an untightening direction for removal of the test cap from the other opening. 3. The box of claim 2 wherein one of the test cap and the bottom wall has at least one tab that is insertable through a notch in the other of the test cap and the bottom wall for engagement with the other of the test cap and the bottom wall upon turning the test cap in the tightening direction to secure the test cap in place. 4. The box of claim 3 wherein the other of the test cap and the bottom wall has a ramp that is engageable by the tab during turning of the test cap in the tightening direction to force the seal on the test cap into sealing engagement with the bottom wall radially outwardly of the notch. 5. The box of claim 2 further comprising a handle on the test cap to facilitate turning of the test cap in the tightening and untightening directions, the handle including a plurality of circumferentially spaced, radially extending spoke-like finger engaging portions for ease of turning the test cap in the tightening and untightening directions. 6. The box of claim 1 wherein the two joined valve mount inserts are insertable in two adjacent openings, and a drain pipe is connectable to a third opening in which the two joined valve mount inserts are not inserted. 7. The box of claim 6 wherein one of the openings is located between the other two openings whereby the one opening is a center opening and the other two openings are right and left hand openings, respectively, the two joined valve mount inserts are joined together in spaced relation a distance corresponding to the spacing between the center opening and the two other openings, whereby the two joined valve mount inserts are insertable into the center opening and either one of the two other openings as a unit, and a drain pipe is connectable to the other of the two other openings in which neither of the joined valve mount inserts is inserted for establishing either a right hand drain arrangement or a left hand drain arrangement. 8. The box of claim 7 wherein the two joined valve mount inserts are connected together by a flange that overlies the center opening and the one of the two other openings in which the two joined valve mount inserts are inserted. 9. The box of claim 1 wherein the housing has a top wall containing at least one opening to allow the box to be mounted upside down with the bottom wall at the top and the top wall at the bottom for top mounting of the two joined valve mount inserts inside the box and for connecting a drain pipe to the opening in the top wall instead of to the other opening in the bottom wall in which neither of the two joined valve mount inserts is inserted. 10. A washing machine outlet box comprising a housing having a bottom wall containing at least three openings, one of the openings being located equidistant between the two other openings whereby the one opening is a center opening and the two other openings are right and left hand openings, respectively, two valve mount inserts joined together in spaced relation, the spacing between the two joined valve mount inserts being such that the two joined valve mount inserts are insertable into the center opening and either one of the two other openings as a unit to provide valve mounts for hot and cold water shut off valves. 11. The box of claim 10 wherein a single lever operated hot and cold water shut off valve assembly is mounted on the two joined valve mount inserts. 12. The box of claim 10 wherein individually operated hot and cold water shut off valves are mounted on the two joined valve mount inserts. 13. The box of claim 10 wherein the two joined valve mount inserts are connected together by a flange that overlies the center opening and the one of the two other openings in which the two joined valve mount inserts are inserted as a unit. 14. The box of claim 13 further comprising means for establishing a fluid seal between the flange and the bottom wall of the box completely surrounding the center opening and the one of the two other openings in which the two joined valve mount inserts are inserted. 15. The box of claim 10 wherein a drain pipe is connectable to the other of the two other openings in which neither of the two joined valve mount inserts is inserted. 16. The box of claim 10 further comprising a snap lock connections between the respective valve mount inserts and an edge of the openings in which the respective valve mount inserts are inserted. 17. The box of claim 10 further comprising a solvent weld or adhesive connection between the flange of the two joined valve mount inserts and the bottom wall of the box. 18. The box of claim 10 further comprising at least one tail piece on the bottom wall of the box surrounding the opening in which neither of the two joined valve mount inserts is inserted for connecting a drain pipe thereto.
