NEWer trailers have pex water lines, low water drain valves and HIGHER pressure rated plumbing.

ANY small comperssor works fine, IF you follow the process described in the OWNERS MANUAL suppled BY airstream.
and LIMIT the air pressure, again as described in the O.M.
the important thing about the compressor is that it is NOT internally lubricated with oil...
we do NOT want to blow lubricating oils into the water lines, so that's an issue.
i've used TINY compressors for this with good results.
and one can UNHOOK the water pump quickly and drain that residual water into a towel...
quick glance, THIS thread would be better place in the PLUMBING or winterizing sections, where there are MANY threads on this issue.
