Put a disclaimer in the proposal/contract that you aren't responsible
for the UG and that you can't connect until the guy that is does his
job.
Our spec tells the sprinkler contractor not to connect to the ug until
they've received the completed ug test papers and we have a copy. We
also, in writing, inform the MEP of the requirement, including the 13/24
flush and test requirements. Sprinkler contractors almost always (very

The reason #3 is so popular is that it is so simple to apply in the field.
Step#1: Open supply valve to riser. (Always direct water flow to a safe
location.)
Step#2: Allow full flow until water runs clear or for at least 2 minutes.
Step#3: Close supply valve and cap riser, you're done flushing.
