was told its just a float to shut it off at the 10 percent area.
should never be filled more than 80%. It's dangerous to so and the new OPD valve makes sure of that. There needs to be expansion room inside the tank. The new OPD valves automatically do that for you when the tank is upright as you fill them. This isn't something new it's always been true. The valve change has been more than a few years ago and they eventually said it was ilegal to refill the old style valves it now is.
The new valves (that you can buy and have installed) basically connect up to an old style connector and the new style OPD connectors. Nothing on the boat changes just the connector used to fill the bottle. All new Backyasrd grills are set up to use the new connector. You no longer need a wrench. The inner part of the fitting is just like the old ones.
Right now here in the US it is not legal
to fill a tank that does not have the valve unless the filing station feels the condition of the tank is such that it is safe. They won't fill the tank as full. Many won't fill them at all. I had an old style Aluminum
tank and the dealer fillers a lot less but will. They could switch it when I went in so I had one old and one new.
If you are filling your own tank by transfering from another I don't see how that changes anything. The OPD valve only changes how they fill not anything else. It's pretty cheap
to switch valves on a tank if you go to a real propane
dealer. I think I spent $15 to replace the valve and purge the tank. Using the standard bottles it's foolish to do that since they are so cheap
and being steel
turn to a pile of rust in a short perod of time. If the tank isn't steel
you can change it over and then not do it yourself.
If your little tank is steel I would work on a replacement because steel tanks don't last. Certainly how you have been doing won't be effected. Given you have not blown yourself up just yet. It sure be nice to keep it that way. Personally, I think handling dynamite is a whole lot safer than propane
. Just like gasoline the static electricity that can build up can ignite propane and it's immediate. You won't live long enough to hear the explosion.
