I recently built a small vacuum press with a venturi using pressure rated<br>
PVC for the tanks.  It required a few tapped fittings into PVC caps, 3"<br>
pipe I think.  Worked fine for the application.  Vacuum press works like a<br>
dream - some very slow loss of pressure but unclear where in the system it<br>
might be and it's slow enough I don't care.<br>

Well done.  Just remember:  Air is compressible.  Water is not.  Makes a fairly significant difference.<span class="im HOEnZb"><br>
