WMOB is a washing machine outlet box. This box is designed as a termination point for all drain and water connections necessary when installing a washing machine. IMOB is an ice maker outlet box, and is designed as a termination point for the water line connection when installing an ice maker.
The WMOB and IMOB are made of a High Impact Polystyrene. The WMOBs can be solvent welded to ABS or PVC drain pipes. Use ABS cements for ABS drain pipe connections and PVC cements for PVC drain pipe connections. Where building officials approve: Oatey ABS to PVC Green Transition cement can be used for either drain pipe material connection to WMOB.
We always recommend that you refer to the washer manufacture instructions to ensure they do not have specific guidelines for finished drain elevations. The maximum height of the WMOB would be determined by the washer manufacture, accessories such as pedestals, and local plumbing codes. Oatey recommends the maximum elevation of the inside bottom of the WMOB is 48? above finished floor. The minimum elevation of the inside bottom of WMOB is 34? above finished floor, this is the same height as the flood level rim of a laundry sink with or without a cabinet.
We always recommend that you refer to the refrigerator manufacture instructions to ensure they do not have specific guidelines for installation. Since there are no drain connections necessary for the IMOB, Oatey IMOBs are designed for any elevation installation.
The date code on all Oatey WMOBs and IMOBs are located on the Master carton and also on the inside wall of the box. The date code stamped on the inside of the box represents the date the box was manufactured, and not the date when the box and valves were assembled. Master carton date should be referenced.

Hammer arrestors are designed to help with water hammer (banging noises) in the water lines when a washer or ice maker are in use. When the appliance?s quick closing valve shuts off, it will exposes any loose piping in the water supply system and make banging sounds. The hammer arrestor helps absorb the shock and minimize or eliminate the banging sound. Oatey manufactures a full line of pipe supports which can assist in securing the loose pipes.
Oatey manufactures valves for the WMOB and the IMOB to accommodate connections to copper, CPVC and PEX connections. Please refer to product category #11 on the Oatey website for the specific valve needed in your application.
Oatey is pleased to announce that we do offer such a valve for washing machine and ice maker connections; it is called the ?Push Connect Valve?. These valves come as part of our Outlet Box collection. They are designed to easily accept ½? Copper, CPVC and PEX pipes, by simply pushing the ½? pipe into the Push Connect Valve Fitting. If for any reason the pipe needs to be removed after installation, no problem. Simply use the quick release tool to remove that section of pipe, and insert the new piece of pipe. No need for solder, pipe joint compounds or thread sealant/Tapes; just cut, de-burr and chamfer (bevel) pipe end before pushing and connecting the pipe.
