Does my GAS IT bottle or tank have a shut off valve in the 80% fill valve?

All GAS IT bottles and gas tanks have a built in check valve in the fill shut off fill valve so should there be LPG in the bottle or tank and you need to remove the fill hose or the fill point or fit on bottle fill points then the check valve in the tank or bottle will see a full pressure drop and automatically shut off.

Even though our products have check valves in the fill valves, we always recommend that any fill hose or bottle connection is removed only when the bottles or tanks are completely empty of LPG and that the work is carried out by a trained GAS IT installer due to safety implications.

Don't forget that even if the bottle or tank is empty that there is a high possible chance the fill hose will have full pressure liquid LPG in it so when you come to remove the fill hose you need to 100% commit to removing the hose for the check valve in the bottle or tank to shut.  If you only open the hose fitting a little way then the liquid will come out, it will freeze the fittings and might then not shut off - plus it will likely empty the tank or the bottle fully.

If you are removing the bottles and storing them for some time we always recommend you that you have a the 2 parts from the GAS IT removal kit to hand so that you can shut off the manual tap outlet and the fill valve elbow on the bottle ( if you removing the fill hose and fillpoint from the bottle or tank.)  These are our part number GI-VAL-V-029 & GI-FH-033 which are sold on our GAS IT webshop

Before you do any work on LPG products or anything that has had gas in them its safety, safety safety.

This information is for GAS IT trained dealers only.  We always recommend getting a trained GAS IT dealer to carry out any LPG work on your GAS IT products because liquid LPG freezes the skin on contact so wear gloves with a coating that stops them getting wet with liquid LPG, wear safety glasses and even a full face mask to stop liquid LPG hitting your face, cover up exposed skin.  Watch out for ignition sources from naked flames, electrical connections ( 240 or 12 volt ) and also make sure you are not near open holes or grids as LPG is heavier than air and will find the lowest point.
