Hi Robertokc
Thanks for your response
Yes you were right there were a few too many questions!!
I would try to cover your points below:
-
I have two meters - one for the house and one for the irrigation. The House consumption is actually fine. We use about 5-6000 gallons a month and that translates to about $60 a month with sewage included.
-
Bill includes sewer but only for the main house portion - the whole point of installing the irrigation meter was to avoid the sewage cost.
-
Indoor usage is fine for now - could it be better? probably but the kids are only 4 years old for now so water consumption is minimal as it is.
-
As for the sprinkler heads etc, my contractor installed the Rainbird 5004 rotor heads and i have a lot of trust in him. My yard has a funny shape and he has come out twice to finetune the heads as much as possible but due to the shape there is some water waste on the street. He has installed these full circle heads: http://www.rainbird.com/homeowner/products/rotors/5000.htm with a precipitation rate of 0.2 to 1.01 inch per hour. They are adjustable as far as arc and circle is concerned. I may talk to my contractor and see if he thinks there will be significant savings if we just change the nozzles to something more efficient… We are at the end of the heavy watering season here in Charlotte so maybe something to look out for next year.
-
The system is brand new and it recently had an inspection with no issues. The contractor is actually on the list of Rachio installers and he has installed a number of their systems already.
-
I have adjusted the square footage already as it was way out. Hopefully that will make a difference in the water graph.
-
The flow sensor will not save me a penny but i think it will compliment my rachio very nicely. Rachio has a support article here: https://support.rachio.com/hc/en-us/articles/115010378947-How-do-I-install-a-flow-sensor-Generation-2-
-
I already use the Fixed Schedule on three days a week for 20 min per zone, 6 zones, therefore 2 hours of watering. I have reduced this down to 10 minutes per zone very recently in a water saving effort. Maybe next spring/summer will give the flex schedule a try and see how it goes.
-
i forgot to mention earlier that i have my own NetAtmo Weather station installed with a rain sensor so my rainfall data is as “local” as it can get.
Hope this helps…Thanks for your input.
