Cant  really comment on the actual plumbing performance but the pics do show very tidy installations.They also show the metal flanges always used by plumbing contractors here and i guess somewhat negate the issue of extreme accuracy being required,sure you have to be close to the money but dead on centre for every hole is probably not required.

Either run it to its own trap or to a flanged tailpiece
No difference between a clogged sink or disposal really. However if the dishwasher is run to its own trap or to a flanged tailpiece at the other sink bowl, the disposal or its trap line clogging up won't affect the dishwasher drain line. Yes, dishwasher have valves that should keep water out, however you know for sure it will work. I don't.

Here is the effort made by the plumber IN MY HOUSE [eek] where the reinstatement goes on after our house fire. New cupboard back required I think!
It started with one little sander

Funnily enough I am installing a kitchen in the refurb I'm working on in the next town. I would get the sack for that above

Going back to the original question, I ran across this suggestion in a newsletter today and thought I would share it.

"Center a drain-line hole in a cabinet By Geoffrey Montague
A quick, easy method for centering the drain behind the back of a cabinet is to take the length of masking tape and twist it so that the sticky side faces out in the middle. Stick it to the wall over the drainpipe. Push a rare-earth magnet into the center of the tape. Next, move the cabinet into its position and place another rare-earth magnet on the inside of the cabinet’s back panel. Move it around until it is drawn to the other magnet. Now you can trace around the magnet to know where to center the drain-line hole in the back of the cabinet."

Just offering food for thought....

"Pipes from the floor are usually a good indication of an island, the air admittance valve reaffirms that."

Not always though. Some times if the sink is on an outside wall I have seen the water lines and drain
stubbed up through the floor as opposed to running in the wall so the chance of freezing is reduced.

Was the "TAMED RAT" in his tool bag that he used to cut that out with not a clue?
Jeez anyone working for me who did an axe job like that would be down the road....

There is always situation where you have to cut out way more than you would like to get access to something, but its how you leave things for the finished job that matters :)

Question for the original post.

Surprised that a T is ok in the plumbing in that the garbage disposal potentially could push water back into the sink ?
