Good morning all. I manage a production facility in Baltimore. Our building is brick building built in the 1940's. The brick and mortar are deteriorating. Reapplying mortar seems easy enough. Is there a recommended coating to be applied to the brick that would help preserve it? I...

I hope it is ok to ask what brand you would recommend.... I have multiple hot water (160 F), tempered water (115 F), and cold water lines of varying size (2", 1-1/2" and 1") through which flow is controlled by normally closed, 120 VAC solenoid valves. The header pressures are close to 40 psi...

OUTSTANDING!!! Thanks guys. You can make a pretty smart fellow like me feel not so smart as the solution truely is quite simple: Three sets of two contactors. Each set has a mechanical or electrical interlock to prevent both from being shut. Two (the primary two) are powered from the two...
