Tony,

Go for option number two. If you are worried about restrictions on your intake go up a size in PVC(ie to 1.5 inch or 1 1/4). Have only the bulkhead as a narrower point. All that will really happen then is it speeds up to get past the narrower point(a venturi basically).

As well if you can put the unions in that Bob has mentioned. If you can justify the cost get a true union. It's a ball valve and union in one fitting. [img]smile.gif[/img]
