Response from Catharine:
Shannon thank you for your kind suggestions. Sorry about the wifi connection problems. It is a project for my next visit - needs a telephone outlet in the rental part of the (website hidden) were over-loaded due (they said) to winter storms, could not come while I was there, took over six weeks even to provide the wifi. Dave (who says the tank problem was "one-off" and nothing to do with the shower) and Goewin both enjoyed meeting you.
