How To Fix A Sprinkler System In A House?

This video provides a step-by-step guide on how to troubleshoot and repair your sprinkler system. It teaches you how to find and repair leaks, blockages, and malfunctions, ensuring your lawn is green and your water bill is low. The video also demonstrates how to replace a worn-out valve diaphragm on an automatic lawn sprinkler system.

To troubleshoot a sprinkler system, ensure the system is turned off at the controller and cut out the damaged section of line. The process includes excavating around the malfunctioning sprinkler head or heads using small shovels, removing the sprinkler head and riser, inspecting the riser for damage, and contacting a professional irrigation company if the wire issue cannot be fixed.

To repair a sprinkler system, excavate around the malfunctioning sprinkler head or heads using small shovels, remove the sprinkler head and riser, and inspect the riser for damage. If a professional irrigation company cannot find and fix the wire issue, you need to contact another company.

To find the leak, look for escaping water or sprinkler heads with little to no flow. Dig up and expose the broken sprinkler pipe to expose the broken pipe. Generally, repairs can range from $50 to $600, plus the cost of any additional parts that may be needed. By following these steps, you can fix minor leaks, blockages, and malfunctions to keep your lawn green and your water bill low.

How do you diagnose a broken sprinkler line?

Low water pressure, standing water, mold, mildew, and lush patches are all signs of a sprinkler system leak. Standing water, especially in areas that don’t usually collect water, can indicate a crack or break in the line, leading to a leak. Mold, mildew, or unusual fungus growth can indicate excess moisture due to leaks, and can show up as slimy patches on the lawn or exterior walls of the home. Lush patches, while greener or wetter than the rest of the lawn, may be receiving extra water from a leak.

Water bubbling up when the system is running is a telltale sign of a sprinkler system leaking underground. Small holes in the yard could be signs of a leak in the irrigation system, as they may be the result of soil being washed away by leaking water. Dirty water may indicate soil or debris entering the system due to a leak or a broken pipe. Animal damage can also lead to leaks in sprinkler lines.

To find and fix a sprinkler line leak, follow these four steps:

1. Turn on the system and identify the zone not working correctly. Look for sprinkler heads that don’t spray properly or have low water flow. This may be between a functioning head and several non-working ones, especially if the area stays wet and soggy.

Why would my sprinkler system stop working?

To address low water pressure, ensure there is no blockage in the spray head or around it, as this could indicate an underground leak or a broken head. Lower water pressure in the neighborhood, especially if 12 houses are built in a year, may also cause a drop in pressure. If sprinkler heads mist instead of spraying a steady flow, it’s a sign of high water pressure. To optimize spray, water usage, and evaporation, install sprinkler heads that regulate water pressure or pressure reducers on valves.

Can an old sprinkler system be repaired?

Approximately 80 percent of irrigation systems can be repaired, including instances of broken sprinkler heads, leaky valves, defective solenoids, and broken wires. Such repairs are typically less expensive than the installation of a new system. In the majority of cases, the installation of a new sprinkler system is not required. However, there are certain exceptions to this general rule. In the majority of cases, repair or replacement of the sprinkler system is not required.

How much does it cost to replace an irrigation valve?

The sprinkler system’s valves control water flow through pipes and spray heads. If loose, they can leak or break, costing between $75 and $215. Valve replacement takes one to two hours and costs between $14 and $150. The backflow preventer, attached to the main water line, prevents water from flowing away from the central water system. It can cost between $280 and $1, 550 and is often the most expensive repair, including labor, replacement, and system testing.

How do you fix a broken irrigation system?

To locate a sprinkler leak, turn on the system, turn off the water, dig up the area above the leak, clean the exposed section, and remove a 4 in section of pipe. Clamp the pipe ends and insert a slip coupling to repair the line. To locate the leak, run water through the system and allow it to run for about 2 minutes before checking the lines. Do this in the daytime to make it easier to spot the leak.

What is the most common cause of sprinkler system failure?

Corrosion is a major cause of sprinkler failure, as it can lead to leaks or valve stuckness. The National Fire Protection Association (NFPA) advises replacing sprinkler systems if corrosion appears during regular inspections, as it can deter performance during emergencies. If a valve is turned off during maintenance or repair, and a fire occurs, it may cause sprinkler failure. If the wet fire sprinkler system fails to extinguish the fire, it can result in severe loss.

Fire sprinkler systems can also fail due to system defects, such as damage to components like the sprinkler head or pipes. These issues can be avoided through regular inspections, repairs, and maintenance by certified professionals. Small protective cages can also be added to prevent accidental damage.

What is the most common reason a sprinkler system is inoperative?

Common reasons for a sprinkler system not turning on include incorrect lawn sprinkler control timer, clogged or dirty sprinkler heads, broken sprinkler heads, broken supply pipe due to lawn mower, voltage issues, defective control valve box, and low water pressure/flow. To check the programming of your sprinkler, inspect the following things:

1. Check the sprinkler’s timer, which should be set correctly.
2. Check the sprinkler heads, which should be clean and free of debris.
3. Check the supply pipe, which may be broken due to a lawn mower.

How to repair a sprinkler system line?

Before repairing a sprinkler line leak, it is crucial to identify the issue. This involves digging out the line, cutting out the broken line, placing band clamps on either end of the piping, fitting the coupling on the pipes, tightening the band clamps, testing the system, and burying the line. Tools needed include a garden trowel, gloves, cleaning rags, hacksaw or pipe cutter, screwdriver, hand torch, band clamps, coupling inserts, new tubing, and stake flags. Your sprinkler system is essential for maintaining lush landscaping.

What is the typical life span of a sprinkler system?

A well-designed, quality-components sprinkler system is crucial for maintaining a beautiful yard and ensuring its longevity. The average life expectancy of a sprinkler system is 20 years, with good quality heads lasting 10-15 years, while inexpensive ones only last 2-3 years. Nozzles should be replaced after two years, depending on water quality and climate. Pipes are the most durable component, lasting up to 40 years before needing replacement. Wires may need regular replacement due to improper installation and corrosion.

Valves provide 10-15 years of service, while controllers last 5-10 years. Irrigation failures and damage can result from various factors, such as the age of the landscape and irrigation system, previous repairs, tree proximity, rodent activity, vandalism, and the quality of the irrigation water. However, the quality of installation and components is more likely to affect the lifespan of your sprinkler system.

What is the life expectancy of a sprinkler valve?

The investment in durable irrigation valves has the potential to significantly extend their lifespan, with an estimated duration of 10 to 20 years. However, the longevity of these valves may be affected by environmental factors such as the local climate and harsh weather conditions. In regions where extreme temperatures or frequent freezing and thawing are prevalent, the accelerated wear of valves may necessitate regular inspections to ensure optimal functionality.
