Help installing gen 2 8 zone unit!

Since you have the back flow preventer, you can leave the master valve open, yes.

Hey just wanted to update that all is installed works perfectly! Thanks for all the help.

Although? Do you suggest turning on the water hammering feature if I use a pump/MV?

Thanks

Aw yis! Super stoked you got it working man. I wouldn’t turn it on. Not unless for odd reason it sounds like someone is smashing your pipe when a zone ends.
