Gen3 flow meter: Where would I put it?

post by johnny2678 on Mar 30, 2018

Need to understand where this would go before I buy. All the docs say after the backflow preventer and the pics show a nice neat installation above ground.

But I don’t have a backflow preventer and all my supply lines are below ground.

I took a video showing the reclaimed water line, which starts at the street and somehow makes it around the side of the house where the controller and the zone valves (?) are located.

Any advice on how/where I can get this thing installed would be appreciated. Thanks!

I have similar questions. The main line for my sprinkler system starts just after the water meter, which is in an underground box out by the street…about 80 feet away from my Gen 2 controller (behind a brick wall, in the garage). The Gen 3 flow meter would be installed by the street in a new valve box. I hesitate to purchase the new system until others report reception successes or failures with a flow meter installed underground. I’m also unsure if we have a backflow preventer. If there is one in the system, it’s underground and I have no idea where it’s located. Like yours, all our supply lines are underground.

@franz @emil Any help from the pros on this? Gen3 is in my cart, just need some more info before I order.

@kevmcgrath @johnny2678 I’ve reached out to our Director of Hardware who will be able to help answer these questions.

@johnny2678 and @kevmcgrath At this time, we are not recommending underground installs. It may be coming.

@brad ok, as long as we get a holdover on the intro pricing.

@Brad FYI - most of the sprinkler system installs that I’m aware of in Texas are fully underground, i.e. no above ground backflow/vacuum breaker. So I’m in the same boat as the others.

Agreed, same here in FL.

Not one home in the 8,000+ in my SC community has above ground irrigation lines. It seems to me you could run one zone at a time (with no other use going) and watch your meter for 15 minutes and get a good idea of the use for that zone. Then just by giving you a way to put in that info could convert any schedule to estimated gallons.

Can’t argue with you there. But in addition to having underground supply lines, not one home in my 8000 acre Florida community has their own reclaimed water meter:-)

My system does not have a master backflow preventer, rather it has six valves each of which has a built in anti-siphon valve ( https://www.amazon.com/Genie-54000-Anti-Siphon-Valve-Control/dp/B000A287DA). It would be easy to install the flow meter on the above ground pipe that feeds the six valves. Is this supported?

You insert the meter near the bank of valves in the main line that is feeding the valves. You don’t “cover with dirt”. You put this flow meter in a plastic irrigation box, just like the underground valves tend to be mounted in, so you can remove the cover of the box for access.

If the wifi signal is insufficient, can use a repeater just as you would to extend the range of the wifi inside your house.

This all makes sense, but will it be supported by Rachio?

@emil @franz I also remember @franz mentioning they might have something to announce regarding underground installs?

@MarkSanDiego - The wireless flow meter doesn’t use WiFi for communication back to the controller. The flow meter uses a 900 MHz radio in the US and Canada.

post by MarkSanDiego on Apr 9, 2018

The flow meter will work fine underground. The only issue is if the radio communication will be reliable between the controller and flowmeter if the flowmeter is under a layer of wet dirt.
