OATEY 38640 Eliminator, Plain Box, No Valves, Washing Machine Outlet Box - Contractor Pack

No valves. The 38640 Eliminator is a plain box, so it ships without supply valves and gives you the drain side only. If the laundry opening needs hot and cold supply shutoffs behind the washer, this is not the box for that job. The 38640 is for the discharge side, where you need a single drain connection and no water supply at the box.

That is what the Eliminator is built for. One connection at the box drains the washing machine hose plus AC condensate, water softener discharge and humidifier lines, so you are not cutting separate receptors into the wall for each one. An engineered clamping system inside holds those discharge lines in place instead of leaving them loose in the box.

No. The 38640 is the plain, no-valve version of the Eliminator, so it handles the discharge side only. For an opening that needs hot and cold washer supplies, order an Oatey washing machine outlet box supplied with valves instead, and keep the 38640 for jobs where the supplies are handled elsewhere or where you are only terminating condensate, softener and washer drain lines.

Yes, it has top mount knockouts, so you can bring the line in from above rather than only from the back. That matters on a retrofit where the existing stack or standpipe comes down from the ceiling bay and you do not want to open the wall below the box.

High impact polystyrene, in white. It is a molded plastic recessed box rather than steel, which is the norm for laundry outlet boxes, and it gets its rigidity from four support brackets that tie it to the framing. The white finish matches the standard laundry box look across a portfolio of units, so replacements on other doors of the building will look the same.

Each 38640 is listed at 2.11 pounds with a volume of 0.443, so a pallet quantity for a multi-family rough-in stays light. It is sold as a contractor pack, which is how it is normally bought when you are boxing out a whole building of laundry closets.
