Yes. Air is naturally present in water supply systems.

Water pipes are pressurised, but they are not completely filled with water at all times. Changes in water demand, pressure and temperature can cause air to enter or be released inside the pipe system.

The amount of air can vary depending on the pressure at different points in the system. When water pressure drops, trapped air can expand and take up more space inside the pipe.

Air can enter a water supply system in several ways.

It may enter through: - Small cracks or damaged pipe joints
- Poor or damaged seals
- Leaking flange connections
- Changes in water pressure and flow
- Pumps operating within the water distribution system
- Main pipe breaks or repairs

Air can also be released naturally from the water itself when pressure and flow conditions change.

Water meters measure the volume passing through the meter. If air is present in the water line, the meter may measure the combined volume of water and air passing through it.

The amount of air can vary depending on the condition and pressure of the water system. In some systems, air may account for a significant portion of the volume measured.

This means that managing pressure and air expansion can potentially help reduce unnecessary charges on your water bill.

Smart Water Valve is designed to help manage pressure changes around the water meter.

It helps maintain a more stable pressure on the upstream side of the water meter during normal water usage. This helps reduce sudden pressure drops at the meter, which can cause air inside the pipe to expand.

Smart Water Valve also helps keep the water meter operating within its intended flow range and can help reduce excessive flow caused by higher-than-required water pressure.

The result can be more efficient water management and lower water costs.

Savings will vary from one property to another.

The actual savings depend on factors such as:

- Water pressure and pressure fluctuations
- Water flow rate
- Pipe size and system capacity
- The amount of air present in the water line
- The property's water usage pattern
- Existing plumbing conditions

Because every water system is different, it is not possible to guarantee a specific percentage of savings before installation.

Based on customer experience, savings can vary considerably between sites. Actual results will depend on the individual water system and operating conditions.

Once installed, Smart Water Valve works continuously as part of the water supply system, without requiring daily operation.

No. Smart Water Valve does not remove air from the water line.

Instead, it is designed to help prevent air from expanding significantly when there is a pressure drop caused by normal water usage.

After passing through the meter and Smart Water Valve, the pressure changes as normal and the water continues to the building's plumbing system.

The Valve is designed for installation on the customer's side of the water meter and, where applicable, after the backflow prevention device.

Installation should always follow the applicable local regulations, plumbing requirements and standard installation practices.

Smart Water Valve is manufactured using durable materials and is designed for use with both potable and non-potable water applications. The manufacturer states that the product complies with NSF/ANSI 61 for potable water applications and NSF/ANSI 372 for lead-free requirements.

For installations in Malaysia, the installation should be carried out in accordance with the requirements applicable to the property and local water authority.

The Valve is designed to fit standard pipe sizes and can be installed by a qualified plumber.

Installation cost depends on:
- Valve size
- Pipe size
- Existing pipe configuration
- Accessibility of the installation point
- Local plumbing rates

As an example, a 2-inch Smart Water Valve typically takes around 45–60 minutes to install, depending on site conditions.

You can use your own plumber or arrange installation through an approved or qualified installer.

Smart Water Valve is designed to help manage water pressure and reduce the effects of air expansion within the water system.

However, the actual savings will depend on the property's water pressure, plumbing system, water usage and other site conditions.

For this reason, savings should be assessed based on the individual property rather than assuming the same results for every installation.

Every Smart Water Valve comes with a 90-Day No-Questions-Asked Satisfaction Guarantee, according to the manufacturer's stated terms.

This gives customers an opportunity to evaluate the product after installation.

Every Valve comes with a 10-Year Manufacturer's Limited Warranty, subject to the manufacturer's warranty terms and conditions.
