<p>George, I need more information about this system- please provide
the following:</p>
<p>indicate line sizes and material on the diagram. I also need the
corresponding attachment fittings information, manufacturer and
part number. If the tubing is plastic, part numbers for the tube
inserts if required by the manufacturer. The same information is
needed on the parts list you provided- some are listing
manufacturer info (Grainger is a distributor, not a manufacturer).<br>
</p>
<p>there is a relief valve on this system- where is the sizing
calculation?</p>
<p>what is the pressure system number associated with this system?</p>
<p>where is this system physically located?</p>
<p>Are there actual mechanical drawings of this system?<br>
</p>
