Why is the 'bottom' valve req'd? The 'top' valve is normally open-- close it, remove the plug, drain the drum, replace the plug, open the valve.
Is there some practical reason for the bottom valve? _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
