Review on Westbrass D320 07 Roman Drain Nickel by Bonnie Nieves

This is a high quality shower or bath drain plug. It can't be seen very well in the picture, but the shadow area is a dimple so the water drains completely. The drain set can be mounted in a suitable plumbing container (not included) with the screws provided, or built into mortar or plumbing putty like a sink like I did with the surrounding tiles. The stopper has a set screw to lock it, raise it and turn it a quarter turn for the up position. I removed the set screw for easy removal and replacement of the connector if needed. The plug is sealed with an O-ring that is not listed on the manufacturer's site or drawing. Correct Replacement Size: Buna-N Oil Resistant O-ring 4mm wide, 42mm ID. Revain has a list of these sizes: M4x42 Buna-N O-Ring, Hardness 70A, Round, Black, Buna-N, 42mm ID, 50mm OD, 4mm Width.
