Changing copper to PEX.
The current copper setup is the original from 1974, all half inch right from the meter. I'm thinking of running a 3/4 inch from the meter (it's one inch coming in to the meter) to a manifold.
My main question is can I put the manifold my crawl space? It's a central location, the water meter is currently located in there, it's heated and had lights and easy access. I'd like to have all the PEX run to a central location, the longest run from the location I want to use would be about 18 ft.
I'm located in Nova Scotia. The person I spoke to from the city referred me to the National plumbing code, I'm currently trying to find a copy.
Thanks in advance
