Hi all.
I have cut some notches in joists to accommodate the 22mm pipe runs.
When it come to positioning the 22mm-22mm-10mm Tees, should I
keep them close to the joist or can I just position them halfway between the
joists?

It's a good idea to leave some spacing (say minimum of 10mm) to allow
for the 22mm pipe to expand and contract without the risk of the
fittings coming right up to the joist.

Other than that, if you are bringing the 10mm pipe along parallel to
the joists, then it may make sense to have the fitting positioned to
allow the pipe to be clipped to the joist without having to put too
big a set of bends in the 10mm.



Also, is it easy or difficult to bend 22mm by hand within a gap between
joists of
about 12 inches?

What kind of bend? if it's 90 degrees, a bend in a 300mm radius is
reasonably easy. If you want to go tighter, then you get metal
formers which clip onto the pipe and hold it in place.
