PEX Fittings And Inside Diameter


I'm replacing the old supply lines at my house and I'm going with PEX. I've pretty much only worked with copper, so this is a first time for me.

I'm using a standard trunk system, without any of those nice manifolds. My house is 1100 sq ft on one level with two full baths.

The main is 3/4" galvanized steel. I'm planning to run 3/4" PEX trunks and branch off with 1/2 to fixtures.

It's obvious that the barbed fittings choke down the ID to about one trade size smaller.

Should I be using 1" trunk, or will 3/4" be acceptable? Being a small house, there aren't any very long runs.

I'd be worried about the old 3/4" steel being choked off by all thethe old sediment and glom.

Are you planning to replace any/or all of it?

As long as your main is 1" you should be okay with 3/4" pex.

The 3/4 steel is my main out of the meter. My meter is all the way at the curb... Meaning that steel runs across my neighbors entire yard. I'd love to be able to replace it but it isn't realistic right now.
