I want to test an old dishwasher before I install it. Rather than having
something blocking up the kitchen, there's a sink and plenty of space in the
garage I can use. Assuming the machine can cope with a 1m rise, I should be
able to drain into the sink, but I'd need to arrange the water supply.

I know there are self-cutting taps, like this:

But they're quite a bodge, and I don't want to install an unsightly tap just
for half a dozen test runs.

I was wondering... the cold tap (which is about 30 years old) has four fins
sticking out about 8mm, and no thread. We already have a 'Hozelock'
connector for it for fitting a garden hose (leaks like anything, but I don't
care in this application). Might there be some way to bodge this connector
onto a supply hose? I have neither the dishwasher nor the tap adaptor
available to check at the moment.

I could mount the Hozelock connector on a new washing machine feed hose by
chopping off one 3/4" BSP connector. Hozelock hoses are 12.5mm - what size
are washing machine hoses? Hozelock have discontinued the tap connector, so
I don't really want to break it.

Would the dishwasher mind about the low pressure (put another way, how good
a test would it be with this arrangement)? There's also an outside tap -
can't remember if it has a screw thread, but it would need at least a 10m
hose run (so we're back to Hozelock again).

Any other suggestions?

Thanks
Theo
