FAQs about WEc2 :

If manufacturer documentation is unavailable and the flow/fixture rate is unknown, how would one go about confirming the flow/flush rates of those fixtures?

We are not able to locate the flow/flush rates of the plumbing fixtures in the project building, so we have decided to test 20% of the fixtures of each fixture type. How do we go about doing that?

If pre-1993 plumbing fixtures are still in place (i.e. the water closets), but their flush valves have been replaced post-1993, does that count as 'plumbing renovation' or fixture replacement for the purposes of the prerequisite/credit?

Yes, you can replace/retrofit your existing hardware with a dual-flush flushometer. There are two things to keep in mind: 1) Since you are replacing the flushometer for the purposes of your LEED project, and since the retrofit is not considered a major plumbing renovation (i.e. no pipes or tile replaced), you are still allowed to count these retrofitted fixture as pre-1993 fixtures in your calculations. 2) Make sure to do a little research to ensure that your existing toilet bowls will still be able to flush properly with a reduced volume of water. Some older toilets that are designed to use 3.5 gpf will not function properly when only 1.6 gpf or lower is used.
