First newbie mistake, not a huge one but being impatient! I started plumbing my water station before my pump arrived, it has 1.5 inch fittings and I plumbed 1 inch. I know I can use fittings and size it down to 1 inch, but would it be better to start over. I can take the unions back and exchange them. Will it make that much of a difference just for my water station? Thanks
