[Killietalk] PVC Manifolds

[Tom McLean <tmac2 at opusnet_com>]

I glue my joints and insure an airtight seal by twisting the wet 
joint.  No problems with this part of the project.  I then hacksaw 
and splice if I need changes.  Even the 1 1/2 inch pipe is relatively cheap.

I had some problems with the screw in valves.  You need a brad point 
drill to make to holes for the tread tap.  Other drills tend to make 
oval or chipped edged holes.  I had some leaky valves where I over 
taped the holes.  About 1/3 of the tap is enough and gives a good 
grip on the screw in valves.  I used the whole length on one and the 
valve blew out, at 3/4 of the length they leaked.

This was a small system with a linear pump.
