SUBMARINE 4-Inch Square Brass Sealed Floor Drain, Preventing Blockage, Odor and Water Reflux, Can Be Connected with Independent Drainage Equipment Such As Washing Machine Hoses.

Or drains at work back up often and were the first in the system so our store used to flood often. And the other stores just kept on using the drain and that would come into our store., now this stops the backlog into our store and the next guy in the line has to deal with it, he used to just blow me offwhen I asked him to not use the drain, but now he cares for some reason.

This floor drain has a great finish on it and installed easily. Only issue we ran into was sizing the vertical stop portion to the actual drain pipe. Be sure to measure the internal diameter of the intended drain pipe and then double check what size you are ordering. If the drain pipe diameter matches the diameter of the device, the built in backflow stopper will not work properly. In other words the pipe needs to be just a little bit bigger than the vertical segment's diameter of the device to allow for the valve to open them close properly. It seems a little bit counterintuitive. This is also a bit pricy for what you are buying, but worth it perhaps if this will be in a highly visible area that calls for a premium finish.

The Submarine floor drain is a great invention that basically functions as a check valve on your washing machine floor drain. Instead of gravity draining into an open insect breeder floor drain, this device has a magnetic flap which closes when the machine is not discharging into the drain. The above floor parts are heavy shiny chrome pieces, and you can use this as a direct replacement of a 4x4 inch floor grate. Even if you have to do some minor modifications to install this, the finished, clean look is well worth the effort.
