OATEY 38483 – Frequently Asked Questions

1) Can the Oatey 38483 washing machine outlet box be used in a 1-hour or 2-hour fire-rated wall?
Yes. The Oatey 38483 outlet box is Warnock Hersey certified for both 1-hour and 2-hour fire-rated wall assemblies. The box body is Bulk Molding Compound with UL-classified intumescent pads and UL-classified insulating material, which is what maintains the rating where the box penetrates the gypsum. That makes it the right choice for multi-family demising walls and corridor walls where a standard plastic laundry box would break the assembly.
2) Does the Oatey 38483 washer box include water hammer arrestors?
Yes, the 38483 is the hammer-arrestor version. The arrestors absorb the shock from the fast-closing solenoid valves on a washing machine, which cuts the banging in the wall and satisfies the code requirement for arrestors on quick-closing valves. If you are replacing a plain box because tenants keep reporting pipe noise, this is the model that fixes it.
3) What supply piping does the Oatey 38483 washing machine box connect to?
This is the CPVC version, so the supply stubs are made to solvent weld directly to CPVC water lines. If your rough-in is copper or PEX, you want a different connection version of the box rather than adapting at the valve.
4) Is the Oatey 38483 a single-lever or two-valve laundry box?
Single lever. One handle controls both hot and cold, so the tenant shuts off both supplies in one motion instead of forgetting one. The valves are brass. If your standard across a building is two separate quarter-turn handles, this is not a match for that look.
5) How is the Oatey 38483 laundry box secured to the framing?
It uses adjustable metal mounting brackets, so you can set the box depth to the drywall face and shift it within the bay rather than being locked to one stud position. The valve and drain arrangement is flexible too, which helps when the standpipe has to come in from a particular side.
6) What is the Oatey part number for the fire-rated CPVC single-lever washer box with hammer arrestors?
Oatey 38483, UPC 038753384832. That number specifies the whole combination: fire rated BMC box, CPVC connections, single lever valve, and built-in water hammer arrestors. Ordering by the 38483 number is the only way to be sure you get the arrestor and fire-rated version rather than a plain box.
7) What color is the Oatey 38483 washer outlet box faceplate?
White, which is the standard finish for laundry closets and matches the typical painted-wall install. Weight is about 3 pounds, so a single installer can hold it in place while fastening the brackets.
