The only thing I've read about this is from bardon saying that the colder the temp the better. I think u'd better email RB if you're planning on spending money to build a water barrier around a room etc. I've looked into it and to get some serious water speed would take some money. Not to mention the price of electricity if you keep that thing running all the time.
3 gallons/minute for a room(12x12) is about $40 US including pump, tubing, sump, and a way to change it out. Pump draws 12 watts, so that's roughly 50 cents/month here for electricity. 2 gallons/minute for a bed is around $26 US.
FYI 11 gallons/minute around a house is about $130 US, and about $12/month to run.
Tap into the cold water supply line beneath a sink,and run the drain end back to the trap under the sink.Drill into the trap either above,or below the "U" shaped trap,as there is always water in there.The water is there to trap the sewer gases,and keep them from coming into the house.
For the supply line: Special "taps" are available that clamp around a pipe,and pierce it,so that no cutting or soldering is required.They have built in shut off. If you have a furnace with a humidifier,look at the water supply connection.
You wont even need a drill. The tap will tap it's own hole,and for the return,you can drive a screw through the pipe,and then remove it. Seal around the return line with putty,or chewing gum.

That will run about $150/month for the water here, and thats at well under 1 gallon per minute. I am a trained civil engineer [;)] I mean 50 gallons/minute of holy water isn't that difficult to implement, well under $400 and $30/month for electricity. If you have to ask where I'd get that much holy water, then you need to read more [:P]
I ran a peremeter around our bedroom with a tiny 1/4" hose feeding off a small ceramic wet saw pump, out of a small bucket of water and back again. I would stop our neg in its tracks if a little light was on like the tv or something, or if it was weak. But if it was charged up (knocking, or moving things) forget about it. Greater quantites like the garden hose was nessasary it hated it even in a trickle, the fresh cool water circulating under our bed and out the window kept away from us but not out of the house. Its all so freaking wild to me I cant believe Im seriously writing this stuff.
2 gallons/minute will stop some but not all. I tested this emphirically by crossing over it. I think pets are a problem also, they get used to cross the barriers.
I'm leaning towards some artificuale Tellurite springs as well, as sort of Omnidirectional generators.
And of course you need to periodically turn them off to let things OUT that manage to cross.
heh, trapped one neutral in my wards around the bed, totally off topic [;)], i made a construct that catches and drains them of energy so they can't do anything, 2 scored last night [:D]
edit: you can try holy hand grenade, it turns negative energy into positive indefinitely, http://www.metatech.org/cloudbuster_&_orgone_generator.html
Roberts book on PSD talks about water barriers. In particular the garden hose being effective. Does anyone have any empirical data? Specifically Gallons/Minute to be effective? I know a garden hose in the US is anywhere from 2-8 Gallons/Minute. I know more is better, but I'm looking for a practical minimum? Same thing for artificail telurite springs?
