Removing a fill hose and the excess flow vale in every GAS IT bottle or tank.

All GAS IT bottles and tanks have an automatic excess flow valve fitting in the 80% shut off fill valve so should there be a sudden drop in pressure in the fill hose or fill point due to a cut or burst fill hose, then the EFV ( Excess Flow Valve ) in the tank or bottle will see a full pressure drop and automatically shut off.

Please note : There is a high chance that the fill hose will have full pressure liquid LPG in the hose its self when you come to remove it, so when you decide to remove the fill hose for any reason you need to 100% commit to removing the hose in one full move for the EFV in the bottle or tank to shut - as it needs to see a sudden pressure drop like a burst pipe.  If you only open the hose fitting a half or full turn then the liquid LPG in the hose will come out, expanding at 270 times to 1, and this will not allow the EFV to shut ( giving you the impression the EFV is not working when in fact the liquid LPG pressure in the hose and also in the bottle is equal and thus there is not enough of a pressure drop on the outlet of the 80% shut off valve for it to shut the EFV off fully.) 

Its also worth considering that not committing to removing the fill hose fully in one quick procedure will cause the valve and fittings to freeze and then even if you remove the hose fully it might not shut off as the EFV will be frozen open which will cause the tank or the bottle to fully empty.

Even though our storage 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.

If you are removing the bottles or GAS IT tank 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.
