Yep, that's basically what I put in. The seat is at the end of the valve at the inside of the wall. The ball valve on the inside wall is just a back-up service valve
I see, yeah, I thought you had to have something like that here too. Just that here, we have open pipes outside the house, valves too. And no basements at all. I have not seen a basement in America since I was in Wisconsin in 2004. So, when I don't see things, I don't really know if you guys have it or not. Usually you have more than I am used to from Norway, just it might take some explaining for me to tell what I mean. It is a hoot when I go to Home Depot and try to explain what I am looking for. :D
