	Hello I have a pressure relief valve that gives out at 15 psig. I wanted to know if the valve needs to be flooded for it to work properly. I am noticing loss of pressure within a container i have and ive tested all other plumbing thoroughly, there is absolutely no leakage there. The tank is filled with coolant. So the question is do i need to flood it?

	I would spray it with soap bubbles and define where the leak is for sure if the valve is on the top of the tank--Coolant(liquid?). 15 psi is nothing and unless it is 720 degrees kelvin, it should hold liquid better than air unless the coolant can digest the material that seals the valve. __________________ Those who believe in telekinetics, raise my hand --Kurt Vonnegut Jr.

	The valve should not need to be submerged to work. The question I have is, is the valve leaking pressure below 15 psi? __________________ Bob

	"I have a pressure relief valve that gives out at 15 psig. I wanted to know if the valve needs to be flooded for it to work properly." 15psig is 15psig wet or dry. Your application/equipment will determine what rating(s) your PRV should have;ie: PSI,temperature,BTU/hour discharge rate. Be safe.
