Does this system meet California's minimum standard for water usage?

Yes, it is 2.0 GPM max for the fixed showerhead (and 1.75 max for the handheld), which meets the CALGreen max.I'm not sure why the Amazon site lists it as 2.5 GPM, might be from a previous generation of the product.Since it's a thermostatic valve with a separate diverter, you can easily control the flow (no push-pull fiddling).I'm personally very happy with the showerhead. Very even, wide water distribution, but more forceful than you would get with a full-width "rain" showerhead.Water can only flow from either the fixed showerhead OR the handheld, not both concurrently.

Yes it does. We just had our new construction rated and this shower pipe met Cal Green requirements.

Yes. You are likely siphoning back through the vent in the faucet. This vent is only required in California. I contacted Watts and the sent me a check valve and instruction to install it and my has worked without issue since (6 - 7) months.

I think the guy in Los Vegas is full of it. If not they waste a lot of water that California would pay dearly for. Ours (mid Kansas) is 1.91 per 1000 gallons. That is 16 time more expensive than he is stating and that equates to 3600 gallons of wasted water per month unless it actually does shut off the flow when the tank is full. I see no mechanism that would do that unless there is a high pressure shutoff somewhere.

Yes, this unit meets California standards and has the correct serial number for use in California. I have had this unit for two years now and no issue. Very good fit as well.

I can't answer that question, depends on your volume of water usage, but for a 4 bedroom home it works fantastic.

I'm not sure it's that critical. I picked up a Walmart standard deep cycle (which isn't really deep cycle), and it works fine - SO LONG AS YOU TOP OFF THE WATER - Every month two two at the MOST. Sorry to yell. But their battery charging "routine" is so messed up it drives me crazy. I'd probably buy a different unit if I was going to do it all over again. The damn charger runs an absorption phase 2-3 times per day.

3 GPM. Or three gallons per minute ona city water system wit a maintained pressure of 45PSI
880122
ABSOLUTELY. I live in Colorado and right now my incoming water is below that (sometimes in the 30's) and it works fine. Now, It will have a difficult time running 2 things like a shower and a sink at that temp but with 1.75gpm you will be set. I've had mine for about a year and love it. This is the 4th tankless water heater I've had and couldn't be happier, it works flawlessly.

I don't know. It is fairly low pressure but I don't know the psi. It is definitely less that San Antonio residential water system pressure.

Yes no problembut its dependent on the water pressure supply it's attached to
2208025
Absolutely , and in the case of multiple systems in one home - its very common to see one installed in the supply plenum of each system. They are rated to 6,500 CFM , we size them up to 5 ton systems.

Yes............this is not a sophisticated watering system and that's fine with me, I purchased it because it works for what I need it to do, water patio plants and a small yard. This is the second unit I purchased, the first one lasted close to eight years (<$50)......thumbs up!!!

Hi, we've had this steamer for almost a year, no problems with hard water deposits in Southern California. This steamer performs well, very leased with the purchase, see my full review for more info. Thanks.

Good question, doesn't seem to have a standard and it would really depend on the water you use. I would replace it whenever it looks dirty. Check monthly or less often if you are using filtered water.

I live in San Fernando Valley and have hard water so every 3 months for 2 people. When water pressure gets low its time to change

The hard plastic bottles were the things that had BPA in them. The reservoir is California Proposition 65 compliant and made of a different material. If Cali says it's safe I'd say it's safe.

No , the built in regulator handles the entire fresh water system when hooking up to city water
