The 1m from drain rule?

Hi guys

actual distance to the gully is 600mm the cylinder is unrestained and it is connected with a rubber hose through the wall.

Also just for a laugh there is a N.G meter running a infinity and heating right there  the lady of the house had the hob converted to LPG then asked us to disconect the N.G meter as she belevied she didn't need it  we did as asked  and funnily enough we were back there within 5 hours when she found she had no hot water  I pointed out at the first visit the faults with the LPG installation but she was happy to leave it as is

Hi Intergrated

I can find nothing in the code regarding a earth rod but when you think about it you are right it could be a potential source of ignition.

For the LPG bottles on a timber sub floor I run a solid barrier 1m either side of the bottles usually Hardie board
