Low water pressure in your facility can be incredibly frustrating, leading to the likes weak showers and slow-filling appliances. Whether you have an unvented system or a gravity-fed one, there are solutions available to increase water pressure and improve the reliability of your daily water supply. In this comprehensive guide, we'll explore how to enhance water pressure in both unvented and gravity-fed water systems. But first, let's go over the basics.
Unvented and Gravity-Fed Water Systems
Before we delve into the solutions, it's crucial to understand the fundamental differences between unvented and gravity-fed water systems.
Unvented Water Systems: Unvented systems are sealed and pressurised, relying on components such as expansion vessels and pressure reducing valves to maintain a consistent pressure.
Gravity-Fed Water Systems: Gravity-fed systems, on the other hand, rely on the force of gravity to create water pressure. Water is stored in a tank at an elevated position, and it flows down to your fixtures due to gravity.
Increasing Pressure In Unvented Water Systems
Check the Current Pressure: Start by checking the current water pressure on your unvented system's pressure gauge, usually found near the water tank. Ensure that it falls within the manufacturer's recommended range, typically between 1 and 3 bar.
Adjust the Pressure Reducing Valve (PRV): If your unvented system has a pressure reducing valve (PRV), it's likely adjustable. To increase pressure, carefully turn the adjustment screw clockwise. Be cautious not to set it too high, as excessive pressure can damage the system and fixtures.
Inspect for Blockages and Leaks: Blockages and leaks can affect water pressure in unvented systems. Check for any sediment build-up or debris in pipes and filters. Address any visible leaks in pipes, fittings, or fixtures immediately.
Verify Pipe Sizes: Consider the size of the pipes in your unvented system. Smaller-diameter pipes can restrict water flow and lead to low pressure. Consult our team of UK experts, who'll assess whether replacing smaller pipes with larger ones is a viable solution.
Install a Booster Pump: In cases where adjustments and repairs don't improve water pressure, you may need to install a booster pump. This device can be placed in the water supply line to increase pressure. Ensure this is carried out by a competent and properly accredited contractor like ourselves to meet local your building codes and set the correct pressure.
Increasing Pressure In Gravity Fed Systems
Check the Tank Height: In gravity-fed systems, water pressure depends on the height of the water tank. The higher the tank, the greater the pressure. If possible, consider raising the tank to increase pressure. However, this will require professional assistance due to structural considerations.
Install a Pump: Gravity-fed systems can also benefit significantly from the installation of a water booster pump. This pump increases pressure by forcing water through the pipes more vigorously, ensuring consistent pressure throughout your facility.
Clean and Maintain the Tank: Over time, sediment can accumulate in the water tank, reducing its capacity and affecting pressure. Periodically clean and maintain the tank to ensure optimal water flow.
Check for Leaks and Blockages: Just like unvented systems, gravity-fed systems can experience pressure issues due to leaks or blockages. Regularly inspect for these issues and address them promptly.
