Pex Al Pex

I have one inch pex al pex inside the house but still need to plumb further. I am curious what my options are for plumbing another 25 feet. I don't have any 1 inch left. Is 1 1/4 inch oxygen barrier pex the same inside diameter as 1 inch pex al pex? Thanks Brian

If you aren't going around a lot of corners.. you may want to price 1" and 1 1/4" iron pipe.. 1 1/4" pex is rather expensive.. and the required fittings are expensive as well.

Good point Greg. My Pex comes up a bit short and I'm using black iron & copper to go the last few feet. It saves buying a whole roll of Pex and the fittings. They sure know how to price Pex fittings!

Yes, they are quite 'proud' of them aren't they???

Would that be galvinized or black iron? Thanks Brian

Black iron is fine in closed loop systems
