FAQs
Q What are WMOB and IMOB?
A 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.
Q What materials are used to make WMOB and IMOB?
A 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 ofcials approve, Oatey ABS to PVC Green Transition cement can
be used for either drain pipe material connection to WMOB.
Q Are there height restrictions when installing a WMOB?
A We always recommend that you refer to the washer manufacture instructions to ensure they do not
have specic guidelines for nished 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 nished oor. The
minimum elevation of the inside bottom of WMOB is 34" above nished oor. This is the same height as
the ood level rim of a laundry sink with or without a cabinet.
Q Are there height restrictions when installing an IMOB?
A We always recommend that you refer to the refrigerator manufacture instructions to ensure they do not
have specic guidelines for installation. Since there are no drain connections necessary for the IMOB,
Oatey IMOBs are designed for any elevation installation.
Q Where is the date code, and how is it read?
A 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.
