What does apressure reducing valvedo

Fuel Gas regs for the most part are based on common sense and experience. When the regs say a tank shall be so far from stuff or a fuel line must be or a regulator shall it is because someone has had a bad experience in the past nobody wants to repeat.

I own my tanks, own the regulators, and own the lines. Bought the regulators less than 10 years ago and last fall, the propane guy told me to expect to need to change the regulators in the next couple years.I suspect but don't know for sure that the old design had some serious flaws and they want to get them changed before something fails on them. When it comes down to it, even owning everything won't exempt me from changing the regulators because if I don't, they won't fill the tanks. I guess I could pay to bury a half mile of nat gas line and switch to that. Wouldn't that show 'em ;-)

You are usually replacing something that is working just fine, that inevitably involves more work than you expected, and inconveniences and causes expense for the customer.  Oh, and it will involve Hell or rain ... either hotter or colder than or it will be raining by the time you finish. And often it means a customer is mad as ...

Most of the government rules and regulations are nothing more than the result of large corporate donations to polititions. When you see some lawyer elected to some position take up his pen and draft legislation that covers something that he has no knowledge of, you can pretty wee guess that he has stuffed his pocket with cash. Much like the Healthcare bill that all of the Democrats passed without even reading it.

edit: The recommended life of a regulator seems to keep changing.  It was a little longer when I started in the business 20 years ago.  I have heard mfg recommendations of 15 - 18years, less under some conditions.  I would say 10 years is an insurance company number, realizing it will be stretched a little most of the time. I've replaced 50 year old ones working perfectly and 3 year old ones that were bad. It's all a numbers game to cover liability.From a gas guy viewpoint I hate switching out regulators.  Once I switch regulators I have to do a system inspection (we're half done with the work of a GAS Check so why not finish it?) and in most older houses there will be some minor code violation we have to fix to put the customer back in service.
