If you have any slope in your yard, blow out from top to bottom zone. I
also remove my backflow over winter.

I shouldn't really be speaking for John, but I<br>
think he is just saying that his backflow<br>
preventer has a convenient port that he uses to<br>
connect.=C2=A0 I don't think he is saying that the<br>
backflow preventer presents any other problem for<br>
the operation.=C2=A0 I am sure John will let us know if I am correct.<br>
