Looks like it was a manual system at one time, someone automated it at another time and did their best to make cross connection prevention. Probably 30 years ago.:)

no, there are two zones piped together. same thing could have been accomplished with one 90 and a T after the valves, eliminating a valve, and doubling the valve size. (theoretically.)

I always used unions on both sides of the assembly, plus sch and brass have a habit of splitting, better way would to have gone brass all the way and died into the sch underground with a sch 80 nipple. Otherwise, pretty clean install. :clapping:

There is a controller in the basement at city hall which would control the drip valves, and they are ordering an hot box for the double check to protect it from the cold. When they set the other backflow i'll get some more pics.

I love to rotors on the side strip of the sidewalk. My guess is that the sidewalk was installed after the irrigation system.

You know I've struggled with the strip side of sidewalks. Have tried various ways to tackle this. In reference to this particular situation let me throw this out. The ground looks fairly level. No sidewalks going to the street just one long sidewalk parallel to the street. I'm betting less water gets wasted in this case if the street rotors are adjusted correctly and have a 170 degree radius. The water draining into the sidewalk strip will saturate the soil up to the curb. When you separate the strip area from the main grass area you add:
A lot of sprayheads that have the potential to break or get run over. A lot of fittings being subjected to clay soil breakage. The soil along curbs shifts a lot. You still get overspray and wind becomes even more of an issue. Pretty good chance more service labor, broken heads, wasted water as a result, etc. will be expended on the strip area than all the rotor areas combined.
In the perfect world cities will put 6-8' sidewalks at the curb and eliminate the strip area all together. Allows for bikers and walkers to share the same path. I'm still not convinced netafim in the strip area will work.

I've seen parks in Bedford with nice wet roads and sidewalks too...keeps the cement from buckling, I guess?

I've wondered if there is a liability issue (or a perceived issue) having the sidewalk so close to the curb? Pedestrians too close to traffic? Although in metropolitan areas like NYC there is mostly cement the whole sidewalk.

Perhaps the strips of grass (or dead grass) are seen as cost savings , by using less cement to build the sidewalk.

You don't want a sidewalk that's too close to traffic.

DanaMac

You don't want a sidewalk that's too close to traffic.

Some of our neighborhoods are like that and some aren't. I prefer the sidewalk next to the curb and street over the PITA strip of grass or rock. Rocks or mulch always work themselves into the street.

Not to mention , watering that strip is expensive on a per sq ft basis.

We need the strips of lawn to provide the irrigation industry with extra revenue, whether they're actually needed or not.

It's the American Way. :usflag:

yes, the plumber didnt want to do the job in the frist place, but it was a city plumber and he told us it he didnt like workning with PVC, just like in the first pics he used copper, well now he has to go back and put the dodble check in the ground because someone at city hall said that would look bad the way it was. we were going to put a cover or hox box over it.

Is that at least galvanized steel pipe?


Galvanized to brass isn't so bad; it's the oxygenated fresh water that will oxidate the steel pipe.

Will it (steel pipe/fittings) be changed over to PVC or copper?

Wet_Boots
04-02-2009, 07:54 PM
It's copper to galvanized that suffers the most. Brass isn't such a risk. In fact, there are some brass stop valves made specifically for going from galvanized to copper, with FPT inlet and sweat outlet.

This is all getting pretty confusing. I take it that we are looking at two seperate POC's at the same building. Couldn't one plumber do the whole job????

Why did they use copper on one location, but Galvy on the other?

:nono:

Some brasses have the same anodic index as copper, both are at high risk for galvanic corrosion when joined with galvanized steel.

I'd hate to take that lash-up apart in a few years; all brass nipple stock with brass unions would have given the manifold more stability as well as ease of service.

Agreed ......... and makes that union pretty much worthless.

Brass/copper -> sch80 -> sch40
