O yee of little faith.
I dragged the old ones sorry little ass to the tip just before.
I decided not too cut up my laminate after a detailed perusal of the job and went back to another suggestion of lifting the worksurface, which I had previously dismissed due to having just resealed it with silicone only two weeks ago.
Swearing and cussing was only employed when me and Mrs Crax came to fit the furniture door and discovered the supplied template was wrong. I made the wise decision of going to the tip while she sorted that bit out
This one is now in, working, not leaking, level and has those clever screws on the front for adjusting the back feet, so I can re-silicone without fear.
I am much satisified.
