The new dishwasher arrived yesterday, unfortunately with a 3/4 inch waste pipe as opposed the the 1 inch pipe of the last one.
We had to be a bit inventive to connect it up to the trap under the sink, but it managed a full load of dishes last night without soaking the kitchen floor.
Now I just need to find a 4 1/2 inch trap adaptor with a 3/4 inch connection for the dishwasher to install it properly – B & Q could only supply a 3 1/2 inch length which makes it a bit difficult to connect everythin without filling the cupboard under the sink with water. 😀
