Kyle, That's the way the ones I have always had were done, and it was designed by the tank manufacturer per NFPA 22. Again it has been over 6 years since I have had to do one.

Is that considered acceptable? Technically the pump suction is on the bottom half and the fill is on the top half, so opposite halves, right? -Kyle M From: Sprinklerforum [mailto:[email protected]] On Behalf Of Bobby Sent: Thursday, February 28, 2019 9:08 AM To: [email protected] Subject: [EXTERNAL] Re: Suction Tank Question If I remember correctly, I have seen the automatic fill lines enter near the discharge. However, it would pipe up the inside of the tank near the top with a turn down and discharge high. This was on large tanks and it has been a few years.

Does that mean that the fill line has to be directly across (opposite) the tank from the pump suction? If I’ve got a tank with a diameter of 90 feet, do I really need to run the fill line all the way around to the other side or is there an acceptable minimum distance? It seems like overkill to require the fill line to be 90 feet away from the suction. I mean, if it was a small tank with a diameter of 20 feet, then only 20 feet away would be acceptable, right? Any thoughts? Kyle Montgomery [cid:[email protected]] Aero Automatic Sprinkler Co. 21605 N.
