Fire Hydrant Testing - Help

[FireFreak08]

I have a project where a flow test was done. The test hydrant was located on a "Street A" nearest the to the incoming service to the building and the flow hydrant was on "Street B" which runs perpendicular to "Street A".

At the end of the project, the incoming service needed to flip. It went from Street A to Street B. My question is, does it matter as far as flow testing is concerned. I learned by the phrase "flow past the test hydrant". In the original test, this is true. However the new layout, the flow hydrant is now closest to the incoming water service. Would this make a difference hydraulically?

I happen to think it would but I could be wrong. Street B could have a smaller main, could have different feeds. I don't really know because the site plan doesn't indicate it.

Also, is there a code/standard that states how often hydrants should be tested?

I think you answered your own question. I can't offer an accurate answer without a more thorough survey of the H2O supply system and more information such as elevation changes, gravity or pumped, etc.

The standarad you are looking for is actually a recommended practice: NFPA 291.

Sounds like a new flow test needs to be done, just to check
