Re: New one to me
Thom,
I my opinion, yes.
The blue (PEX?) line from the DWV WILL BE contaminated *all the time* from bacteria entering from the waste connection.
That puts the contaminated water right up there at the hose bibb.
If you look closely, you will see two hose bibbs and one line, which means that that 'draining line' is to be moved from hose bibb to hose bibb, you know, so they can make sure they contaminate BOTH potable water lines.
I don't see any backflow preventer either.
For something like that, you would need a major multiple purpose backflow preventer - did you go to the Watts site and order those DVDs? If so, watch the one of Backflow Prevention, if not order them and then watch it.
