CS-2009 WEp1:Water Use Reduction

Adjustable valve for WC fixtures

Dear all, The project has 2/4 LPF WC fixtures specified, and the water calculations done accordingly. The Contractor is suggesting a WC fixture with a maximum flush rate of 3/6 LPF, but with a regulating valve that can decrease the flush rate down to zero. In other words, the WC fixture can be adjusted to provide 2/4 LPF, but can be easily adjusted later on to a higher non-compliant flow rate. Has anyone had experience with the USGBC with such types of WC fixtures? Thanks..

George, I think you might get questioned on a valve that can increase the flush rate, given the likelihood that it could be changed in the future.
