How Indexing Valve Works

How an Indexing Valve works? Indexing valves are activated by sufficient water pressure being turned on and off. Therefore, no electrical wiring is required to the solenoid valve. All that is needed for an indexing valve to operate is a controller to turn on and off the water supply (pump or solenoid).

How do you change a Fimco indexing valve?

Directions on how to replace your Fimco Stem and Disc Assembly: Loosen the coupling nut from the coupling. Unscrew the 6 or 8 screws around the perimeter of the valve. Remove off valve top Work the stem & disk assembly up into and out of the valve top until it disengages. Insert the new stem… via

What does a sprinkler indexing valve do?

An above ground indexing valve for sprinkler irrigation systems can control all zones, eliminating the need to dig into the ground to locate electric solenoid valve boxes. The indexing valve works either manually or fully automatic with a controller to turn the water supply on and off (pump or solenoid). via

Why does my sprinkler system skip a zone?

If the pump is located more than a few feet from the water source, the inside valve disc pops up and down, skipping zones as the supply line fills with purging air. via

How does a Fimco indexing valve work?

One above ground Fimco Valve controls all zones eliminating the need to dig into the ground to locate electric solenoid valve boxes. The FIMCO Hydro-Indexing Valve works either manually or fully automatic with a controller to turn on and off the water supply (pump or solenoid). via

How do you install a Fimco indexing valve?

How does a pump start relay work?

A pump start relay is a relay box that activates a pump every time a zone is activated from the controller. Zone valves are the individual valves that operate a group of sprinklers or drip emitters. Hydrawise controllers support 6- to 54-zone valves, depending on the model. via

How much is a sprinkler pump?

The average price of a new well pump falls between $200 and $800 depending on size and type. Submersible pumps range between $200 and $1,200 while jet pumps cost $100 to $800 before installation. Average Well Pump Prices. The average cost to repair your sprinkler system is $75 to $250, with most homeowners paying $212. via

How do you prime a sprinkler pump?

Does each sprinkler zone have its own valve?

An irrigation system is typically divided into several zones, each of which feeds sprinkler heads in a different area of the lawn or garden, and each zone is controlled by a valve that receives signals from a centrally located controller. Often the valves are located inside one or more in-ground valve boxes. via

Why does my impact sprinkler get stuck?

Water pressure that is either too low or too high can cause sprinkler head jamming. When water pressure dips below acceptable limits, the sprinkler head may get stuck at one side of its arc or it may not move at all. If water pressure is too high, it may also cause the sprinkler to stop or jam. via

How do I fix low pressure on my sprinkler system?

If this is the only issue, the fix is simple: access your backflow valves and open them completely to improve your water pressure. Most backflow preventer devices have two pipes: one that is horizontal and one that is vertical. via

Can a pump start relay go bad?

Most irrigation controllers use an external pump start relay to send power to the pump. If the coil or contacts on the pump start relay are bad then the pump will not run. Likewise, if the irrigation controller is not sending that 24 VAC signal to the pump start relay, then the pump will not run. via

Why do I need a pump start relay?

A pump start relay is an electrical device that allows your irrigation timer to communicate with the pump. This device is imperative when you are using a pump to supply water to your irrigation system. Pumps are built to use normal house currents; the relay changes the irrigation timer to normal household voltage. via

How do you wire an irrigation pump?

Connect the copper ground wires from the pump and breaker panel together. Twist them and cap with a wire nut. Connect the wires from the irrigation controller to the 24 volt wires inside the relay box. These wires will relay when to turn the pump on and off during irrigation cycles. via

Does a sprinkler pump need a pressure tank?

Yes, the pump for the irrigation system needs a pressure tank. The pump relies on system pressure to start and stop. The system pressure in turn is mostly governed by the size of the air cushion in the pressure tank. As the air cushion expands as water is used, the pressure goes down. via

Do I need a booster pump for sprinkler system?

For example, say your irrigation systems needs 85 PSI of pressure to operate, but the water line coming into your property only has 60 PSI of pressure. You would need to have a booster pump installed to increase the pressure from 60 to 85 for your sprinkler system. via

Can a submersible pump run a sprinkler?

Most pumps you encounter will be centrifugal, submersible, or booster sprinkler pumps. Submersible sprinkler pumps are simple and effective when they're used in a deep source of water. Centrifugal sprinkler pumps are a great option for shallow sources of water because they use a hose to draw water into the pump. via

What causes a pump to lose its prime?

Leaks on the pump's intake line as well as around the shaft seal of the pump housing itself can cause your pump to lose its prime. Obstruction-One possible reason your pump may be losing its prime is an obstruction or blockage in a line. Debris blocking the suction strainer or foot valve is the most common cause. via

How long does it take to prime a sprinkler pump?

Start the Pump

You should see water flowing from the irrigation system within five minutes. If there is lots of air in the inlet line, you may need to fill the pump housing with water several times until all air has flowed out. via

Why is my sprinkler pump losing its prime?

A pump that repeatedly loses its prime during irrigation cycles may have a leaking mechanical seal, a leak in the suction line, debris clogging the suction screen, or a leaking foot valve. via

How many sprinklers can you have on a zone?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home's water capacity was 10 GPM, you could place 3 heads per zone. via

How many sprinklers can I run on one line?

With your 10 gpm flow rate at your spigot, you could run two sprinklers at 5 gpm each. The best set-up is to run two hoses from the spigot–each to one sprinkler. Suggested sprinklers for this set-up are the Residential Sled Base Sprinklers or the Tripod Sprinklers. via

How many solenoids are in a zone?

As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want. We support up to two solenoids per zone output, plus a master valve, for a total of three solenoids at any given time. via

How do I adjust the distance on my sprinklers?

How do you unstick a sprinkler head?

Lubricate the sprinkler head with spray lubricant if pushing it down with the water turned on had no effect. Spray the lubricant generously around the shaft and wait for it to soak for a minute. Then push and pull the head to loosen it. via

Can you increase water pressure by reducing pipe size?

Squeezing the water into a smaller pipe will not increase the water pressure! As water moves through a hose or pipe there is a lot of resistance caused by the hose or pipe surfaces. The water moves through the hose at the maximum speed it can while still overcoming this friction. via

Where is a backflow preventer located?

Where is the Backflow Preventer Located? You should have your backflow prevention assembly installed inside an above-ground enclosure. It's the safest and most cost-effective place to put it. via

What causes low pressure in sprinklers?

The most common cause of low water pressure in sprinklers is the backflow preventer valves not opening fully. There are two main pipes in your backflow preventer – one horizontal and one vertical. Each pipe has a handle that can be turned to run with the line or across to open the valve. via

How do you know if your pump relay is bad?

If you had the 120 there, turn on the sprinklers and check across the two "load" terminals. That should be 120. If it IS, pump bad, if not, then check for 24 volts between the red and white. If you have 24 volts, relay bad. via

What is a QD relay?

QD Relays (Solid State)

The reed switch consists of two tiny rectangular blade-type contacts, which bend under magnetic flux. It is hermetically sealed in glass and is located within a coil, which conducts line current. via

Why is my irrigation pump not working?

If your sprinkler pump will not start, there are a few possible causes: The voltage at pump motor is too low. Pressure switch contacts are dirty or burned (valid only if controlling pump with pressure switch). Power wires are loose / disconnected. via
