I am trying to plumb a Waterbox 330.7 and have ran into an issue. Can anyone that has plumbed in a 1200 to 1 1/4-inch or larger lines explain how they did it? I have not been able to really find anything on this. I know it comes with 1-inch connections but do not want the reduction in size unless there is no other way. I would really like to plumb in the main drain to one side and the secondary to the other.
Any advise would be appreciated.
