Sounds like a nice setup.
Took a long while to work out
Previously I had a std 10 gallon tank with twin cylinder compressor on top that could not keep up with the big air tools
Then we needed something for the 1" gun the landlord got for working on old farm tractors so I got the hydrovane ( really quiet ) compressor & receiver .
In the mean time he got the roadwork compressor really cheap so we could tow it into the paddock to work on stuff in situ so the hydrovane sat there .
Then I got 10 retractable air reels with 30' of hose on each & saw how the professional workshop had set things up.
Never thought of using blue line water pipe before and of course it is dirt cheap & so easy to install.
Being that all the lines are 1" there is no pressure drop and now most of the hoses I use are 10' to 20' and that makes a really big difference so the only long hoses are used for painting with a LPHV gun so having 60' of hose on that is no problem.
Been going to get some 1" outlets for ages but the number of times I need to use the 1" gun is not enough to justify the effort & the big gun lives in the back of the compressor trailer and that is 1/2 mile away .
