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..
