Installation Methods

DrainHub Installation Method A
Method A

Installation beside the main drain line can offer maximum flexibility and can be achieved with the use of a simple drain tee adapter fitting.

DrainHub Installation Method B

When possible, as in cases of new construction, it can be beneficial to run parallel drain waste systems to separate waste from the sink from other appliances and devices.

DrainHub Installation Method C

It is possible to install the DrainHub in the main drain line under a sink. However, this position can result in more audibly noticeable drainage of waste containing a significant amount of air.

DrainHub Installation Method D

Use DrainHub on a standpipe to connect a washer discharge, softener drain line, furnace humidifier, A/C condensate, R/O system drain and more.
