Residential fire sprinkler systems

[LightningCrash]

Dry pipe systems are not common in residential applications. Most residential fire sprinkler systems are of the wet pipe style and are in fact under pressure, all the time. The water supply is a big determining factor too. Being a 1-story is a plus, allowing access to the attic. The pipe would probably need to be "tented", to protect against freezing, unless you went with a soffit system, which would hide the pipe in the corners where crown molding would be. “Tenting” is where once the pipe is installed and tested, you remove the insulation that is underneath the new piping, place a 3 to 4 foot wide plastic “visqueen” strip over the pipe and insulate over the top of the plastic. This allows the ambient heat from the occupied spaces below to be trapped in the space where the pipe is installed.

Do the wet pipe systems still have inspection and drain fittings?
I could see a situation where if the power went out, you'd want to kill the water pressure to the dwelling and drain the pipes.

Yes they should have a shut off and drains.
