Quick Answer: How To Find Buried Sprinkler Valves

The cheapest and easiest way to find buried irrigation valves is often to probe the soil with a thin rod, such as a long screwdriver. Often you can estimate the rough location of the irrigation valve, then find a buried valve box by probing the ground.

Will a metal detector find sprinkler valves?

A metal detector is unlikely to work because the valves are most likely to be plastic with very little metal in them. If you don’t have any luck probing small low spots near the begining of the zone, it may require someone to do a wire trace for the valve.

How deep should sprinkler valves be buried?

In most areas, burying the pipes 8 to 12 inches below the surface is adequate. This measurement is from the top of the pipe to the surface of the soil, which means your trenches must be slightly deeper to accommodate the pipes.

How much does it cost to find sprinkler valves?

Sprinkler System Repair Cost by Type of Replacement Type of Replacement Average Replacement Costs (Parts and Labor) Valve Box $75 – $125 Filter $75 – $150 Solenoid $85 – $150 Valve $85 – $150.

How do you find sprinkler heads without turning them on?

Pull a metal garden rake gently over the area of the grass where you suspect sprinkler heads are located if you cannot turn water on to the system. If the sprinkler heads are buried, you may need to apply greater pressure to the rake so it digs slightly into the soil.

Should irrigation valves be buried?

Valves can be grouped together in manifolds, or installed individually – and valves should always be buried inside a plastic irrigation valve box. Never bury a valve directly in the dirt.

How long do sprinkler valves last?

One of the components that you may need to replace regularly are the wires, often due to improper installation and corrosion. Valves will give you 10 to 15 years of service, while controllers 5 to 10 years.

How much should a sprinkler valve replacement cost?

Sprinkler Valve Replacement Cost. The cost to replace a sprinkler valve runs about $12.50 to $40 each for most models, plus labor expenses. The valve controls the release of water to the various zones in the yard.

Why do sprinkler valves leak?

The most common reason leaks occur is that the rubber parts in the valve box have worn out. Water seeps freely through the system when the diaphragm seal breaks or debris is obstructing the valve from closing. A broken or aging sprinkler valve diaphragm seal only gets worse over time.

How far apart are sprinkler heads?

Types of Sprinkler Heads Because of the lower PSI the distance of the spray rarely exceeds 15ft. Meaning that spray heads should never be placed further than 15 ft. apart as this would create dry spots (i.e. dead grass) in your lawn.

How many zones can a sprinkler valve control?

Can I run more than one zone at a time? For the controllers HC, PROHC, HPC, you can only run a single zone at a time based on the power output available. Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties.

Do sprinkler valves have backflow preventers?

When installing a sprinkler system, you will install valves that control the flow of water, as well as emergency shut-off valves. While anti-siphon valves have built-in backflow prevention (also called cross-connection control), you may need or want to install additional protection.

How do you trace an irrigation wire?

In automatic irrigation systems, a third way to find lost valves is to follow the wires from the controller. The wires run alongside the PVC pipe to the irrigation valve location. Dig small holes every ten feet to trace the wire. Be careful not to cut the wire.

How do you know if a sprinkler valve is bad?

Signs of issues in sprinkler valve: Water not turning Off: If you notice that water is not closing off from the sprinkler, then there seems to be an issue in the diaphragm valve. Leaks of water: Broken Sprinkler Head. Stuck Valve. Wiring: Irregular Watering:.

How long does an in ground sprinkler system last?

How Long Do Sprinklers Last? The average lifespan of a professional in-ground sprinkler system typically is around 20 years with consistent winterization and care.

When should you replace sprinkler valves?

If your system is nearing 15 or 20 years old, it could be time for a replacement and an upgrade. Newer sprinkler systems are designed to optimize water usage to lower consumption and costs.

Can a bad sprinkler valve cause low pressure?

One of the leading reasons for low sprinkler water pressure relates to the valves on your backflow preventer device. If you notice limited water pressure in your sprinkler system but normal water pressure inside your home, then the problem might be that your backflow preventer valves are not completely open.

What causes a sprinkler valve to not shut off?

If your irrigation system does not turn off, you need to isolate the problem. This starts by checking the main water line and the controller. If those are working, then you need to locate the valves and check to see whether they are dirty, the diaphragm is torn, or the solenoid is broken.

Where is the sprinkler valve located?

Often the valves are located inside one or more in-ground valve boxes. The tops of these boxes will be at ground level, and these, too, are usually fairly easy to spot and access. The valve box, or sometimes the valves themselves, are sometimes buried underground. This is where it can get challenging.

Are sprinkler heads Universal?

A replacement sprinkler head doesn’t have to be the same brand as the broken head. But it does have to be the same type: pop-up (stationary, rotor- or gear-driven rotor) or impact. And the new head must also match the inches-per-hour (iph) or gallons-per-minute (gpm) delivery rate of the old head.
