Hi Don;
      I suggest you go ahead and do your plumbing
without the o-rings in place. The seals should NOT be
installed until you are reasonably ready with your
installation.

There are a few reasons for this.....first an unused
captive o-ring will take a set (loose some of its
squeeze).......second o-rings have a shelf life and
should be inspected periodically for resilience, dryness
etc.
Third and lastly, Paul and I will be handing them out
for free :-)
Save your money...........You have a long ways to go :-)
