Low and high water pressure issues can be frustrating, especially when it affects the efficiency of your reticulation system which it inevitably does. To be able to find the right balance and achieve the perfect pressure, the system needs to be assessed. Some of the issues with flow of water are easy to identify and can be corrected above ground. But below ground level problems may require digging, are more serious and usually involve costly repairs.
Pressure problems can lead to but are not limited to the below:
- Loss in reticulation system efficiency including lack of coverage or no proper head-to- head coverage or overspraying.
- Damaged pop ups and pipes if pressure is too high over time. More regular replacement to counteract the pressure and keep the water flow going.
- Misting occurs when pressure is too high and blows away in the wind so the garden is not watered properly if at all.
- Waste of money and water and negative impact for both plants and lawns: dry patches to the lawns or over watering/puddles, death of plants not being watered adequately…
Some of the common causes behind low and high pressure in reticulation systems and potential solutions to help you address the issues effectively.
Pipe Blockages:
One of the primary culprits is pipe blockages. Over time, sediment, mineral deposits, or debris can accumulate inside the pipes, restricting the flow of water. Common causes of blockages include trees roots, rust, scale buildup, or foreign objects entering the system sand, rocks etc.
Solution: Clearing the blockage typically involves flushing the system or using specialised equipment to remove obstructions. Regular maintenance and periodic pipe inspections can help prevent blockages from occurring in the first place. Flushing the pipes will be beneficial and will prevent damages. This is recommend to be done by a professional.
Insufficient Water Supply:
Insufficient water supply can result in reduced pressure throughout the reticulation system. This issue is often observed in areas with high demand or limited water resources. Additionally, inadequate water pressure from the main supply can contribute to low pressure in your system.
Solution: Contact your local water authority to investigate and address any issues with the main water supply. If you are experiencing high demand, consider implementing water conservation measures and optimising your reticulation system to ensure efficient water usage.
Pressure Regulator Valves
A malfunctioning pressure regulator can disrupt the balance of water pressure within your reticulation system. This device regulates the pressure between the main water supply and your household plumbing, ensuring a consistent flow.
Solution: Replace the faulty pressure regulator or have one installed if you don’t have one. Properly functioning regulators will help maintain optimal water pressure throughout your reticulation system and help water your garden properly. Your waterwise expert can install or replace a pressure regulator.
Undersized or Oversized Pipes:
In some cases, the diameter of the pipes in your reticulation system may be inadequate to handle the required water flow. Undersized pipes can restrict the volume of water, leading to low pressure at various points in the system. Oversized pipes, will cause high water pressure meaning they will supply too much water to the sprinklers and overwater the area.
Solution: To improve and get the pressure, we would recommend to get the system assessed and change the pipes accordingly. Our reticulation experts can service and advise. If necessary, we can recommend an upgrade to the pipes to accommodate the desired water flow and improve pressure.
Leaks or Damages:
Leaks or damage to pipes, fittings, or valves can cause pressure loss. Whether due to corrosion, wear and tear, or external factors, such as tree root intrusion, these issues can significantly impact the performance of your reticulation system.
Solution: Inspect your system for visible leaks or signs of damage. Repair or replace any compromised components to restore water pressure. In cases where the damage is extensive or difficult to identify, consulting a professional is advisable.
Understanding the causes of low pressure in your reticulation system is crucial for effective troubleshooting. By addressing pipe blockages, ensuring an adequate water supply, checking pressure regulators, evaluating pipe sizing, and resolving leaks or damage, you can restore optimal pressure and enhance the performance of your reticulation system.
If the issue persists or seems complex, consulting an expert in the field will help identify and resolve the problem effectively.
