Hey guys. Im looking for a good article on grey water drains. Does anybody have a link?
Thanks.
Check to see if they are allowed in your area first.
I know you must have fretted over this, as most do. It may help your research. 
Not sure about your area but here in New England grey water has to go into the septic or sewer.
If there is a water softening system then the back wash is allowed to discharg to a dry well.
After asking around, grey (gray) water drains are allowed outside most cities.
Interesting fact. I did a Google search for “Grey water drain Michigan” and found this very thread listed among the search results, top of page 2.
Wow, that was fast.
Is there a requirement to have them discharge into a dry well?
Yes, however I could not confirm that they had one.
so is there a difference in the material of gray (grey) PVC and white PVC?
Funny Robert.
Thank you Nick. I couldn’t find this due to my search “Misspelling”
235,000+ pages on InterNACHI’s website. It’s getting ridiculous.
Some people have no sense of humor. :roll::p;-)
