I'm working on a urinal flush valve and ended up having to replace the urinal. The new urinal is a hair lower than the old one and the flush tube will not fit. The rough in did not allow for tolerance and I need to know how to extend the flush tube without having to redo the rough in for the valve or the drain. The old flush tube barely stuck into the spud but now I have a gap of about a 1/4". Any ideas?
How do you extend a urinal flush tube?

On the urinals? Yes they do suck if everything isn't perfect.

I always called that the vacuum tube, Sloan tells you to rough them in at 11.5" above the flood rim of the fixture.

Good catch, I should have said top of urinal, flood rim of toilet.

Sloan always tells you to ruff the water in 11 1/2 above the fixture height that is a mistake. If you have a urinal that isn't just right you can end up short. If you read the Ruffin sheet for the urinal it will tell you that dimensions may vary plus or minus a 1/4 of a inch,thus the reason for shorting the Ruffin height to 10 1/2 inch.

That's a good idea, it's a lot easier to cut a tube than order a longer one. It seems that most of the china is made overseas, and the QC is non-existent. you really need to brace your water stubouts good, the brickies love to push them over, so they don't have to make cuts in the block.
