Unfortunately, the PVC Store in the previous posts doesn't have any 
dealers in the metropolitan Washington DC area. I sent them an email 
asking about mail order dealers, but does anyone else know a mail 
order source for the more unusual PVC fittings?

I'm primarily concerned with the 3- and 4-way edge and corner connectors.

As long as I'm talking about PVC, I've been thinking of building a 
drip watering system from rigid PVC.  I had wanted to use the 
"creatively leaky" black rubber drip hose, but I haven't been able to 
find a consistent supplier for hose couplings that attach to the hose 
sizes available.  Did talk to a couple of the manufacturers, and they 
said that the connectors they use are intended for machine crimping 
only.  Small-diameter clear tubing is another possibility -- it's 
certainly used for aquariums, and, back in my days as a chemist, 
fittings were available through the laboratory supply catalogs. Not 
cheap, though.

What I think might be the best compromise is to cap rigid PVC, 
setting up a jig in a drill press to put holes through it at regular 
intervals. Getting efficient layout goes back to my original question 
of finding unusual couplers (i.e., beyond 3-way flat tees and 90 
degree elbows).

Has anyone done this?  If so, what size did you make the holes and 
how far apart did you space them?
