Sprinkler system

The city lowered the water pressure a while back, and now my sprinkler system's first station doesn't work too well. The rest are okay. The problem is, the guy who installed them made station one too big. A quick estimate is that there are 25 heads on this single station! That's crazy. The second station only has 7, and the rest are in that ballpark.

How easy is it to break up a station? I'd like to make at least three stations out of it. I don't even know what would be involved, as the control boxes are buried and I haven't dug them up to refresh my memory of what it even looks like down there.

Will add that when he put these things in, the pressure was high enough that station one was okay, but not great. Now, most of them don't even come up, and the rest are weak.

Re: Sprinkler system

Well, first of all your controller has to be able to handle the extra stations, if not, you'll need a new one. Here's where I don't know how it works. Are all the solenoids that control the valve on each sprinkler head, wired into the controller in your garage. Or are the solenoids grouped to some device buried in the ground and then that device is wired to the controller.

If it was the former, it would just be an issue of how you wire up the controller. If it's the latter, then you're gonna have to do a bunch of digging.

I'm really just guessing here.

They also make booster pumps for your home water pressure.

Hey, No wonder the water don't work! This pipe is full of wires!!

Re: Sprinkler system

I believe it's the latter. I know there are six enclosed "boxes" down there. I will almost definitely need a new control box, because I think it's locked to 6.

This will probably require an expert.

Re: Sprinkler system

If you know where your "buried" junction boxes are, you can open them up and see if there is any additional room in them. You would need to run underground piping from existing junction boxes (or newly installed ones) to the points where you want to break up your large zone. This also will require that you have some idea of how the underground piping is routed from head to head.

Twenty-five heads to a single zone is a very poor design. Our 9 zone system has no more than eight mister heads or four rotating heads per zone.


I agree.

Re: Sprinkler system

That sounds something like what a builder would do. He hires a go to do it he'll tells him to put it in the cheapest way possible. "Contracter grade" is not something that's bragged on.

Re: Sprinkler system

Dave, I posted when you posted so I missed it. This booster pump you mention sounds very promising. I'll definitely check it out.

Re: Sprinkler system

I have never used one, but I considered one for my house. For a while there, our pressure was low enough that you could actually see the city water pulsing as it came out of the shower. They corrected the issue though. In your case, it might be a better alternative than ripping up the yard to install new pipes and give you back the pressure that you were used to in the rest of the house.
