We did some service work at a building that has a pressurized tank for water supply. This is the third time we went there that the air compressor to the tank was off. The company that does the inspections happened to be there and my service guy asked why the compressor was off. His response was that an engineer told him that after you pressurize the tank, you turn the compressor off. I always thought that you keep the compressor on to maintain the tank pressure, similar to a dry system, to keep the pressure higher to push all the water out of the tank if you need the entire supply. The compressor does have a pressure switch on it.
Am I correct on this thinking or am I missing something? Jay Stough, CET Doylestown, PA _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
