Just a safety tip.....after you remove the caps, tighten the remaining cap, in this case a2.5" !!!!! Many times after a leak, we use hydrants to get the air out while filling the main. Especially in cold climates ( dry barrel hydrants) we often ,,do to time constraints, shut the hydrant and put the cap on only a couple of turns to,allow the hydrant to drain. Even though we intend to return and tighten the cap, sometimes that never happens!!!!! I have seen people hurt from being hit by caps, thinking they were secure!!!
Hi Matthew - We agree, when assessing the capacity of a water main for fire protection purposes the two hydrant test is the correct test to perform (which we also have a video on). However, this test is appropriate to confirm the proper function and output of an individual hydrant.

If you are doing a 5-year flow test of the private service mains, this is incorrect. NFPA 291 states you should use 2 hydrants not 1.

well they were not doing a 5 year,
