Since a lot of water is going to be released during the test they want to make sure the sanitary sewer can handle all the water with the main drain fully open under city pressure.

It'll resolve both 1ΒΌ" and 2" main drain discharges. Steve From: Sprinklerforum [mailto:[email protected]] On Behalf Of Tony Cetani Sent: Thursday, April 26, 2018 1:51 PM To: [email protected]<mailto:[email protected]> Subject: main drain flows Long time reader, first time writer.....actually not that long I'm a fairly new designer. We have a jurisdiction where they require the main drain to drain to a sanitary sewer and the contractor is asking what the flows will be so they can size their SS line accordingly. The sprinkler system hasn't been designed yet and they said they need to know right now so they can finish their design and submit for permit. Is there a way to figure this out (or get a ball park) just based off city water flow numbers?
