81903Re: Inexpensive GPM meter
- May 8, 2013What I meant was I need to determine the peak demand in GPM in normal usage so the so the bucket method won't be of help.
The peak GPM usage would be the best way of properly sizing a mixing valve.
This is for a nursing home and the 1-1/4" pipe supplies for about 50 patients with 12 bathroom sinks, 2 tubs and 1 shower.
The mixing valve tech support were finally able to make a mixing valve recommendation based on the city water pressure and the pipe size.
Thanks all for your insight.
