    I’ll have 1” PVC coming out of my pump. I am going to tie it into my existing county water line coming into my house. That line is 3/4” poly and is in my crawl space. My pump will be in my garage. Should I reduce to 3/4” right out of the pump? Or maybe just before the county line? Or somewhere in between. There will be maybe 6’ distance between pump and existing county pipe.

    For a two bath home I use 1" pipe. The only time I've run 3/4" was for a one bath home.

    Well, there’s nothing I can do about the 3/4 that’s there. I guess I’ll run the 1” all the way to it. That’s the best I can do without replumbing the whole house. Thanks.
