The voice of reason in an ocean of bone heads.
Or, is it a single misinformed plumber that fits your needs?
Answer shopping is alive and well among forum users...
Some even go to multiple forums to shop for answers...
As you read his words he states an expansion tank isn't needed and that is hardly a win for you trying to sell a relief valve...
As for Fire Suppression Sprinklers he doesn't even know what is coming soon...
Yes, Residential Sprinkles are rapidly being adopted by many states all across the country...
They are however very different from what he thinks they are.
For the guy that wants to save a life with house sprinklers, wait until he gets the bill for NOT passing flow test, and he needs a 3000 gallon tank and a 3 HP pump installed. Better skip his next car: and that car with all the new air bags is 25,000 times more likely to save him and the kid than 500 miles of sprinkler pipe.
It's pretty simple Ballvalve, Fire sprinklers do work and they do save lives...
Although it is highly unlikely that you can edumicate yourself... I've enclosed a link below with the data from Scottsdale.

It's too much to hope for that you would read and comprehend it...
So here is an easy to follow video that might work...
The unsprinklered live burn reaching 1500 degrees in 2 minutes is impressive but if you were in there you would have probably been incapacitated and dying well before the 1 minute mark...
As you were lying on the floor your clothes you were wearing would ignite when flashover occurred...
VS.
The Maximum Temperature of 178 degrees and fire under control with sprinkler activation in 14 seconds.
The New Residential Sprinklers are quite different from your flow tested, dedicated systems with a 3,000 gallon tank and a 3 HP Pump. Maybe you should test your brilliance by reading about them, before you bash them. Maybe read NFPA 13D and gain some knowledge, that would be unique for you considering you shoot from the lip and stick with it. But if you want to remain ignorant continue thinking that the $15K per home figure the Home Builders Association is throwing out there is correct.
The new Residential Fire Sprinkler Standard is actually a system where the slightly larger domestic water supply is looped through the house to supply sprinklers and terminates supplying plumbing fixtures. Using materials such as CPVC and PEX they are far more economical to install than you imagine.
In my 26 years as a firefighter I've seen my fair share of charred bodies, trust me it doesn't seem like a very nice way to go and I bet every one of those fire victims would have loved to have one of todays residential fire suppression systems save their lives as well as their families.
I'll never forget a call for a car fire / car accident we were dispatched to late one night. The vehicle was found by a state police officer and called in by him. The victim was trapped in the car and the police officer was trying to get him out. The victim begged the police officer to shoot him as he was driven back by the heat and gave up on his rescue attempt. The officer was very shaken by that incident as was I.
COMMON SENSE - Redwood missed that distribution day before the stork dropped him off.
I got a LOT of family in the last say, 80 years. All over the world. Not one funeral for a water heater bomb, a house fire, or poisoning from a garden hose. But now we all protection from them by LAW - we are criminals without them!
This country is being poisoned by a pack of overeducated and lily white college grads that never got their hands scratched or dirty.
Oh You are so right Ballvalve...
So many things today are designed to prevent idiots from hurting themselves and others from what they do...
Everything you are being protected from has actually happened.
Obviously common sense alone is in too short a supply so additional help is needed to protect people like you.
Should you muddy the effort by spreading your lack of common sense?
And RW stirs the pot...."Yes, of course welds are exempt from metal fatigue"...
Welds dont blow at 10 or 20 PSI. Submarines fail when AUXILIARY systems cause it to drop like a rock to beneath its design pressure.
So going above pressure and pressure cycling a water heater is a good idea?
I'm not sure what your 10 - 20 psi is coming from I surmise we are back to talking about the jet aircraft again. Go ahead and design a welded aircraft. We'll see how many pressure cycles your design makes it through. I'll put my money on the engineers at Boeing, McDonnell Douglas, Lockheed, Martin Marietta, and AirBus for my ride thanks. You can ride in yours...
As to the stupidity about stress cracking in your water heater: BS - My air compressor runs between 90 and 175 PSI for 25 years all day, and just loves it. Maybe you would put a expansion tank on it?
Water does not compress, Air does compress...
I would hope that you know that...
But, when you are dealing with idyuts take nothing for granted....
Your brother seems to be the smart one in the family...
