Why do my sprinklers turn on twice?

A common reason why a program is repeating is that you have a second start time set. The start times control the exact time your ESP-Me timer will begin to water and they also control how many times a day your timer will water. The ESP-Me allows you to set up to 6 start times per program.

Why wont my sprinklers turn on?

Backflow Device Valves If your sprinkler system won’t turn on or if you have low water pressure, this could be caused by the valves not being turned on all the way. Just locate the valves and make sure they are both turned on (you should have 2 valves, one located on the horizontal pipes and one for the vertical ones).

Why are some sprinkler zones not working?

Although it sounds simple, if none of the zones are coming on, first check to make sure the main valve for the system is open. Failing zones may also be caused by an electrical problem, which can manifest as a problem with the timer, the valve, the solenoid, or the wire. Frequently, a bad connection may be responsible.

Why is my Hunter irrigation system not working?

If your controller shows irrigation running (Flashing Sprinkler Icon), and your sprinklers are not working, you may have a wiring problem at the valves or the irrigation water supply has been shut down. If the sprinklers do not turn on you may have a valve shut down that supplies the irrigation system.

Why does one sprinkler zone have low water pressure?

Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.

Why do my sprinklers stay on?

There are two reasons why sprinklers would continue to run with the controller Off or Unplugged: It’s possible your valves were opened manually. The solenoid is located on top of the valve and looks like a cylinder with two wires protruding out of it.

How do I know if a sprinkler solenoid is bad?

Signs You Have a Problem

The Water Won’t Shut Off. If you have this problem, it’s very likely the solenoid.
Low or Uneven Water Pressure. The solenoid controls the water pressure.
Water Leaks. There are many points in a sprinkler system that can leak.
Current Testing.
Valve Inspection.
Parts Replacement.

How do I fix low water pressure in my sprinkler system?

Backflow Preventer Valve Issue 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.

How do you find out where your sprinkler lines are?

You can tell (roughly) where the pipes will be for that zone by finding the shortest path from the valve box that connects all the sprinklers in a zone. As long as you dig carefully, you shouldn’t have too much trouble. The pipes are usually pretty tough and are usually buried about a foot or so under the ground.

How do you find a hidden sprinkler head?

Measure the distance between visible sprinkler heads with a measuring tape. Sprinkler heads will likely be spaced evenly in a set pattern across your landscape. Look for an unusually wide gap between otherwise evenly spaced heads; a buried sprinkler head may sit midway between them.

How deep are irrigation lines buried?

6 to 12 inches

How far can you run irrigation pipe?

LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length. MAXIMUM FLOW CAPACITY: ½ tubing can handle a maximum of 240 GPH or 4 GPM.

How do you bury irrigation lines?

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 many sprinklers can I put 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.

How Far Should sprinklers be from house?

2 feet

What should be the distance between two sprinklers?

Sprinkler Head Distance and Spacing Requirements

Hazard Level	Coverage (in sq ft) per Sprinkler Head	Maximum Allowed Distance Between Sprinkler Heads
Ordinary Hazard 1 & 2 (areas with moderate concentrations of flammable materials)	130 sq ft per head	15 ft

How many sprinklers can I run off one hose?

For example, you generally have a flow rate of 10 gpm from a ¾-inch spigot where you connect your hose. 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.

Can you increase water pressure by reducing pipe size?

You have simply traded reduced flow for increased pressure. The same thing would happen in your sprinkler system if you used smaller pipe to increase the pressure. The smaller pipe would restrict the flow of water. The reduced flow would reduce the pressure loss in the pipes, resulting in more pressure.

How many drippers are in a zone?

How Many Emitters are Needed? 1 or 2 emitters per plant, depending on the size of the plant. Trees and large shrubs may need more. Obviously, using two allows for a backup if one clogs up (which happens now and then, even on the best designed and maintained drip systems.)

How many gallons per minute do I need for my home?

How Many Gallons Per Minute Do You Need for Your Home? This is a loaded question, that really comes down to preference and the number of individuals that are in the home. The average household needs 100 to 120 gallons per person per day, and a flow rate of about 6 to 12 gallons per minute.

Why does my hunter sprinkler system run twice?

A common reason for a controller to repeat a cycle is too many programmed start times. Only one start time per active program is required, a second start time will cycle the program an additional time.

How do you turn off interval watering on Hunter Pro C?

Under the Water Days or Days to Water dial position on your controller you have three options. You can have the program run on specific days, an odd/even schedule, or an interval schedule. To move out of the Interval mode and back into one of your other two options simply continue pressing the (<=) or (=>) buttons.

What causes multiple irrigation zones to work at the same time?

5. Water is coming out of multiple zones at the same time: For the valves to stay open in one zone, while shutting outlets in other zones, there needs to be a minimum amount of water pushed through the valve.

Why my sprinklers don’t pop up?

Check all the valves to make sure that none of them are partially closed. A partially closed valve will reduce the water pressure and water flow to the sprinklers and this will cause them to not fully pop-up. If your valves have a flow control, check and make sure it is completely open.

Can one sprinkler valve control two zones?

Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.

Why does my sprinkler system skip a zone?

Jumping or skipping zones is the most common issue faced by indexing valves. Sadly it’s not the indexing valve causing the issue but rather how it integrates with the rest of the irrigation system and how that system is operating. For example, issue number one: The Faulty Check Valve.

How much does it cost to fix a sprinkler valve?

Sprinkler Repair Costs Valve replacement averages about $12.50 to $40 per valve in addition to labor. Some heads can cost as much as $30 each, and brass valves range to $100 or more. Sprinkler systems are a great way to maintain your lawn.

How do I increase the pressure in my drip irrigation system?

Steps:

Attach a pressure gauge to the end of the garden hose that’s supplying water to the irrigation system.
Remove one of the emitters (drip nozzles) from the irrigation tubing and attach the pressure gauge.
To improve water pressure and flow, divide the irrigation system into two zones.

How long should I run my drip irrigation system?

30-minute

Why is it better to irrigate at night instead of daytime?

According to Kao, water vapor migrates upward during the day and downward at night. Watering your lawn in daytime, says Kao, could result in up to 80 percent of the water being lost to evaporation. By watering your lawn at night, when water collects on grass and leaves, much less water is lost to evaporation.

How deep do you bury drip irrigation?

six inches

Can you bury a garden hose underground?

CAN I BURY A GARDEN HOSE? In short, the answer is yes, you can bury a garden hose for your water transportation needs. Temperature fluctuations, your ground type, and the types of burrowing and digging animals you have in your area could impede the purpose of having a buried hose i the first place.
