I posted this question concerning the Delta Valve. I thought that I was logged on. Has anyone experienced any problems with the Delta Valve feed line configuration? I can also see another potential problem with this gap. When the Drum is put in Warm-up, this area would hold condensate (oily-water). When the Hot Feed is switched into the Drum, it seems to me that this condensate would flash and cause a pressure spike. Has anyone experienced this?
