We have just replaced the gas bottle on our month old kexin geyser and now it does not want to ignite. please help

SOURCE: I have had a Totai gas geyser installed model 1051-119/1-RSA-12-A 12 Litre. The cold water drain valve has started dripping water. How do I stop that? Gas input is a 48 kg bottle.

if i understand you correctly you are reffering to an expansion valve. as the water is heated the water expands. there is an expansion valve to stop excess pressure in the system. if the valve keeps dripping when the unit has finished heating then you might be able to clean the valve seat free of dirt or calcium build up. other wise just replace it. under no circumstances should you put a lid on it.
