#1 on our post-Christmas list is to get the DC working more efficiently and easily, with less hose changes to use a device. Building the Thien cyclone separator
was a good start, and now I'm putting up 4" DWV pipe so I can keep the DC in the closet, minimizing noise and mess.
A couple questions for the knowledgeable masses:
1) Does it matter if I use a 90 deg fitting vs. 2 45 deg fittings? Will it *really* matter as to the efficiency of the system?
2) If it doesn't matter, then does that include any lines off the main trunk? My basic layout is a main trunk that goes through the middle of the shop ceiling, and then branches going to the wall and down.
3) Does it make any difference where the blast gate goes? Do I need one as close to the main trunk as possible, and then also one at each device coupling, or is the one near the main trunk useless? Some branches will probably serve 2 or 3 devices (each with blast gates).
4) Some of these connections are really tight with just friction. I'm too uncertain about my final layout to glue at this point, so I've just been using the friction fit. Where the fit was somewhat loose, I wrapped electrical tape around the male fitting until the connection was much tighter. I also thought just friction fit would be a good idea in case of having to clear clogs, but I know I could just put an extra Y on for that, or an end cap. Is friction fit good enough, or will I be leaking air even though I can't feel it?
Thanks for all the help!
