I'm installing a backflow preventor valve(1/2") on a new boiler. The boiler has a domestic hot water coil with a presure relief valve (3/4"). Can I connect the vent off the backflow preventor to the relief valve's drain pipe thru a metatl/metal check valve? The floor is wood and has no drains except from the a pipe from the coil's valve thru the floor leading out doors. Boiler relief valve is seperate pipe. |
