    Default Re: pin hole leaks in copper pipe

    a 90 is full port meaning it does not taper down to a smaller diameter threw its bend and has the same id as a fully reamed copper tube.. the flow restriction is very minimal and a system installed with fully reamed tubes does not have major flow fluctuating thus eliminating erosion but it could be many things like water from a well source with old or no ph neutralizers
