Hello,
Perhaps this is a daft question but these nozzles that are advertised as an "appliance adaptor" to connect your washing machine (and presumably dishwasher or spin dryer) to your 40 mm waster pipe, how good are they?
Does the waste pipe from the machine just push on? I'd be worried that it might wriggle free and flood the floor; do they would need restraining with a jubilee clip?
Thanks.
