Thanks everyone. Back to Bunnings for me to get the tubing extension once i see what mm diameter it is. Can get the socket for me to complete Operation anode change too. Poor kiddiwinks, always dragging them about doing stuff for the van! Being a 2007 van i do wonder whether i would get anywhere if i approached Jayco with a few issues i have, like the yellowing of bathroom walls which i see has been discussed on forum. The rust seems superficial and U-Bolt ok to my untrained eye, thankfully. The van park we are at has very high water pressure so i wonder if that is contributing to the higher dripping output as bigman0510 said, or whether it is just because of the high usage i put the hot water under doing endless dishes etc. (A woman's work is never done- wah wah wah). Perth caravan show starts tomorrow- can't wait!
