Oh tittle

Finally managed to get out and check on the boat.

So I can relax I have wriggled under the tug deck and switched off the stop cock and opened a tap.

However I am too late to save the bath/shower mixer unit.  To be fair that wouldn't have been the tap left on anyway so I imagine the either/or knob would still have blown off.

Anyone know if it is possible to get replacements for these or am I likely to have to replace whole unit?

I will of course have to check all joints when I come to turn water back on. 

Plus I didn't have time to check the calorifier joints but these are fairly well insulated she says hopefully.
