Some things to consider:

Fire sprinklers do in fact saves lives & property, emphasis on lives, you can always buy more crap.

Frozen sprinkler/water lines:
A well engineered sprinkler system will not have the line running through an unheated space e.g. the attic, garage or exterior walls.
If the owner decides to throttle the heat to a portion of the house low enough to freeze his lines and cause property damage... whose really at fault here?

Damage to sprinkler heads from kids:
Sprinkler head manufacturers do make "Concealed Residential Sprinklers", they are basically flush with the ceiling and you only see a smooth concealing escutcheon (trim plate).
Sidewall sprinkler heads actually do stick-out into the living space but they do offer low profile heads to be less obtrusive e.g. the Tyco Series LFII (TY2384) Residential Flush Horizontal Sidewall Sprinklers comes to mind.

260 gallon bladder tank?!? From a mechanical perspective I would use a pump and a storage tank if your water supply is iffy.

Accidental discharge is a non-issue just look at the stats.

Lets get this straight, 26 GPM from 2 (TWO) sprinkler heads.
Yes, it'll be a mess if a sprinkler head fuses, it would be a BIGGER MESS if there were no sprinklers and the firemen had to use their 2 1/2 hoses & axes to put the fire out.

In a nutshell these residential sprinkler systems are Life Safety Systems (to protect lives NOT property), when there's a fire (god forbid) the smoke alarm is suppose to give the family an early warning to get the hell out. If the fire grows enough to fuse a sprinkler head the drop in system pressure will set off another warning (usually a horn/strobe), the water pattern formed by the sprinkler head is designed to contain the fire in that area so as to give the occupants enough time to escape and to give the firefighters a "safer" fire to fight.

Mike Guertin I respect your knowledge and admire your work but in your post you said "Put those funds in a locked account to keep politicians away.", that what the Social Security/Ponzi scheme was suppose to be, these corrupt politicians still call it a TRUST FUND.

Rick reviewed 16 finish nailers.
He hit on 11 features to consider when purchasing.
His favorite finish nailer is the Bostich.

Great job on the video review!
