anyone familiar with calgreen and multiple showerheads
we want 2 showerheads in the masterbath and I am trying to read up the requirements. I am having trouble understand it, poor reading.
it says "they technically meet the plumbing code because each head can be less than 2.5 gallons per minute"
and then it says "the combined flow rate of all showerheads shall not exceed the maximum flow rates specified in the 20 percent reduction column contained in Table 4.303.2 or the shower shall be designed to only allow one showerhead to be in operation at a time" (2.0 gpm)
1. so is it allowed or not to have more than 2 showerheads?
2. how much is each shower head gpm need to be?
3. hansgrohe/grohe valve with diverter only allows one function at a time. Should I get 2 valves one for each control? is it possible to have 1 central mixing valve, then output to both showerheads, and each shower head has it's own on/off control? is this allowed?
can anyone clarify?
