I'd think water in the "P" trap would solve that problem? MIght have trouble doing a 50.59 saying your RP device won't increase the consequences of a design basis event or increase the frequency of an event by failing and not permitting water to drain.

Please use caution when opening. Does anyone use devices in their floor drains that prevent positive air flow out of the drain but allows the drain to work as designed. We at STP find particles around the floor drain due to positive air flow up through the drain There are rubber check valves we are researching Thanks Roger Sent from my iPhone Powernet - a service of the Health Physics Society Power Reactor Section To post message: Send or Reply to: [email protected] To unsubscribe: send message to [email protected] archive(Nov2015->): http://www.mail-archive.com/[email protected]/ archive(<Oct2015): http://www.mail-archive.com/[email protected]/ If questions, contact E.
