but if there WAS an average, how long?

How long does the average 1" residential value under proper design and duty, last before it's diaphram needs to be replaced?

define average

If you install good stuff, you should measure the service interval in decades.

I've got a yard full of Rain Bird PEB valves at home that are around 12 years old now (about 96 of them). Never had to tear a single one down yet or repair one. My mom's house has some Rain Bird brass valves that were installed in 1986. Of the 12 valves in that yard at least 8 of them are original and have never been cracked open or re-built. I think it all depends on how the system is designed, what the water is like and what kind of pressure you have. Of course if you install junk to begin with then it won't last very long.

It really depends on the valve you're talking about. The Hunter SRV seems to only last about 5 - 10 years, others last longer and some less. I've found that the valves without any plastic in the diaphragm are more durable than those with it. The plastic parts (like the ring on the bottom of the SRV diaphragm) are always the first to go.

Depends more on water quality then anything else.

Hunter 1.5 to 2" PGV's from what I have seen lately: 5 to 7 years (We do not like or install Hunter Valves)

Rainbird 1" DVF or PGA should be a solid 10 years plus.

Rainbird PEB's in all sizes: 15 years plus (We are going on our 16th year so that all I can say)

PEB's go in on all of our commercial and high end residential projects. The PEB is an awesome valve and the "scrubber" is all we use for non-potable water.

We do not install Toro, but they do make some damn good valves. Everyone just hates watching the bleed pins blow out of the valve box and then get lost. LOL

I remember when they changed the black bleed screw to a green one. They could have made it orange so we could find it in the grass after it blew off but no, they went with green.

the bleed screw and pin is a newer wrinkle on that valve - it used to be a plain brass bleed screw and a diaphragm assembly with a screen

I think the flo-pro had a life expectancy of about 2 days or 200 gallons..... Whichever came first.
