Inquiry (采购产品): 00 cartridge circulators how does the in-line circulator have to be installed--we are having trouble in maintaining constant hot water circulation from the in-line hot water heating unit. the plumber has placed the taco unit parallel to the floor of the HW closet. is there a reservoir in the unit that has to serve as a head to accomodate the circulator and provide constant hot water to the house users. is there a cut-away or cross-section of the unit available??thanks **** Hidden Message ***** manuel sirgo 4016 trinity court midland, TX 79707 USA Company: m.a.sirgo, operator Title: home-owner Phone: 432-694-0650 Fax: 432-699-1362 E-mail: masirgojr@aol.com **** Hidden Message ***** masirgojr@aol.com
