Here is response the Webber BBQ manufacturer provided me when I complained of a
malfunctioning OPV valve:
Hello,
Thank you for choosing Weber! I'm sorry for the gas flow issues you are having
with your Genesis E-330 gas grill. If the grill is having intermittent problems
with lighting, possibly the safety device in the regulator may have been
activated.
Since 1995 all regulators (the part that attaches to the gas tank to regulate
the flow of gas) have included a safety device that restricts the flow of gas
in the event of a gas leak. This safety device can be inadvertently activated
in two ways, putting the grill into what is commonly called "bypass". The first
way for the device to be activated is to leave one or more burner control knobs
in the "ON" position when the LP cylinder valve is opened. The second is not to
wait long enough to "start" the grill after opening the LP cylinder valve.
The safety device in the regulator is activated each time that the LP cylinder
valve is opened. The device resets itself when the gas pressure equalizes
between the closed burner control valve and the regulator, through the hose. If
a burner control knob is turned on before the gas pressure can equalize, the
device will remain in "bypass". The length of time necessary to wait to "start"
the grill after turning on the LP cylinder valve is dependent on the length of
the hose and outside air temperature. It is always good practice to wait at
least 60 to 90 seconds after opening the LP cylinder valve before turning on
the burner control knob to start the grill.
Keep in mind that the safety device reacts to a gas leak. If a grill is in
bypass, the gas connections and hose should be tested for leaks with a soap and
water solution.
If the grill is in bypass, after checking for gas leaks do the following to get
the grill out of bypass:
Close the LP tank valve
Turn all burner control knobs to the OFF position
Open the grill lid
Allow the grill to reset for at least 1 minute
Turn the LP tank valve until it is completely open
Wait 60 to 90 seconds
Turn the front/leftmost burner to the HI/Start position (at 9 o'clock position
if control knobs are on top right, HI/Start facing straight-up if control knobs
run across front of grill)
Press the igniter until the burner is lit.
Turn remaining burners to High (If control knobs run across front of grill,
turn each knob to HI/Start and light with igniter button individually)
Close the lid.
The grill should preheat to 500-550 degrees in 10-15 minutes
NOTE: Cold weather can delay the time it takes to equalize the pressure.
When you are done grilling:
-Turn all burner control knobs to the OFF position
-Turn off the LP tank valve last

Assuming I get a OPV valve, how is that going to effect the operation of my
propane stove and water heater? The water heater is a demand system that
lights when water flows.
I switched over the valves on my system a few years back, and have seen no
difference in the way things work. I'm not quite sure why someone would have
problems; the ONLY thing the OPV valve does is keep the tank from being
over-filled, sort of like a relief valve, but based on the actual propane level
in the tank, not the pressure.
Another question; can I get the clear fiber glass tanks that are tall and
narrow to fit the locker?
I've only seen the 10- and 20-lb tanks in the fiberglass.
Still; another question; how and where do I get a tank recertified?
You should be able to take them to any major propane distributor; they can
change out the old valves to OPV, and should be able to advise you on where to
get re-certified (assuming they can't handle that themselves). But by the tim
you pay to replace the valve AND re-certify the tank, a new tank might be the
better option.
