Bob, Steve is saying that you absolutely have to include them if you are using the manufactures' equivalent lengths, if the manufacture shows an equivalent length for a tee on the run in their cut sheet.

Am I missing something?

Sent: Friday, September 23, 2011 10:11 AM To: [email protected] Subject: "flow through tee's and Hydraulic calcultions" Hello forumites, I'd like to pole the forum and see what the consensus is on accounting for flow through tee's or "tee on the run" when calculating a system. NFPA states that they do not need to be included when using the schedule 40 fitting table. But when using manufactures' fitting equivalents, do you include them? -------------- next part -------------- An HTML attachment was scrubbed...
