Greetings everyone.............Ok, here's the story.I have a account that has a 10 year old system.It's a Perlick, 5 handle,approx. 60' run, with cooling blocks at the faucets.The owner and I have done a good job with cleaning and P.M.'s over the years. Just this past month, have been having major problems with maintaining proper temp. Have replaced hi-lo limit switch, pump, put new glycol(m.m.'s) in.The resivoir tank shows 32-34 deg.,using a probe type thermometor,but the products at the handles show a solid 46-48 deg.This is for all 5 handles,no varience at all. Consulted the draft tech from our local distributor, he thinks that it's possibly plugged or clogged in glycol lines.Is there a filter for the glycol lines? Like for a fuel filter for a car?Does Glycol gel or develop build up over the years?Personally, I don't think the owner is telling me the whole story,believes that he can fix anything,(ala Tooltime). Any advice would be helpful, for I'm sorta challenged at times when it comes to glycol systems. Thanks for reading my tale of woe. Cya....BrianatKCDraft.
