This summer I'm replacing my hand fed coal boiler
with an Axeman 130 stoker and thus its time to make some
plumbing up grades as well.
My boiler, in the garage, and distribution manifold in the
basement are 1 1/4" piping. Going between the two
is an existing 1" line with lots of 90s. The distance is about
70' in an almost unaccessible crawl space. I have most painfully
fished some electrical through the area and left plenty of pull
lines for the future. With one of the lines I fished through
2 1/2" pex lines for domestic water. It was easy.
OK for the question.
My thought was to run an 1 1/4" pex supply and return.
Some issue came up.
1st, 1 1/4" is really expensive.
2nd, manhandling the coil of the stuff is going to be at best a nightmare
in the tight area.
3rd, to make the turns I'm still going to have about 8 90 elbows.
So I was thinking to make this easier, cheaper and perhaps more
efficient was running 4 lines of 3/4". 2 for supply and 2 for return.
I can easily make a manifold at both ends. 3/4" pex can easy to fish through
and can make the sweeps without any elbows. It's also a lot less expensive.
What do you guys think.
