Inquiry (采购产品): Tacocartridge circulator, model number 006-B4 I built my home in late 2002. I put a circulator in so the water on the second floor would get hot quickly. What's happening now is I turn the shower on and after about two minutes it starts to get cold. If I turn the shower off and back on in about 30 seconds to a minute, it gets hot again. After about a minute it gets cold again. This continues to happen. It also happens in the kids's shower. Would a new circulator solve the problem??? What could be causing the problem? I would appreciate you professional opinion. Thank you, Phil **** Hidden Message ***** Phelim Giblin 18944 USA Company: Giblin E-mail: cpgiblin@aol.com **** Hidden Message ***** cpgiblin@aol.com
