Q&A

What type of fluid is the A-115A gauge designed for?

 The A-115A Pressure Gauge is specifically designed for use with water-based fluids. It is commonly used in systems like the Sloan flushometer, where it measures the water pressure in plumbing applications. 

What is the pressure range of the A-115A pressure gauge?

 The A-115A Pressure Gauge typically has a pressure range of 0 to 160 psi (pounds per square inch). This range is suitable for monitoring the water pressure in systems using Sloan flushometers, ensuring that the pressure is within the optimal range for efficient operation. It’s important to make sure the pressure is regularly checked to avoid any malfunctions or inefficiencies in the flushometer system.

How should I properly install the A-115A gauge to ensure accurate readings?

 1. Choose the Right Location

Install the Gauge Near the Flushometer: Place the A-115A pressure gauge on the supply line near the Sloan flushometer, where it will provide an accurate reading of the incoming water pressure.
Ensure Accessibility: Position the gauge so that it is easily visible for monitoring and maintenance. Avoid installing it in areas where it may be exposed to damage or extreme conditions.

2. Check for Compatibility

Verify that the gauge is compatible with the plumbing system you are installing it in. The A-115A is designed for use with water-based fluids, so ensure that it will be used in a clean, non-corrosive system like the Sloan flushometer.

3. Threaded Connection

Use the Correct Fitting: The A-115A gauge typically comes with a 1/4″ NPT (National Pipe Thread) connection. Make sure the fitting on the gauge matches the corresponding threads on your plumbing system.
Apply Pipe Thread Sealant: For a secure connection and to prevent leaks, apply a small amount of Teflon tape or pipe thread sealant to the male threads of the plumbing connection before attaching the gauge.

4. Install the Gauge

Screw the Gauge Into Place: Carefully screw the gauge into the threaded fitting. Hand-tighten the connection to avoid over-tightening, which could damage the threads or the gauge itself. If necessary, use a wrench to tighten it slightly, but be cautious not to apply excessive force.
Ensure Proper Alignment: The gauge should be oriented so that the dial is easily visible, and the needle can clearly indicate the pressure level. Some gauges may have an adjustable base to help align the dial.

5. Check for Leaks

After installation, turn on the water supply to check for leaks around the gauge. If you notice any leaks, shut off the water, tighten the connection, and reapply pipe thread sealant if necessary. It’s essential to ensure that the installation is watertight to get accurate pressure readings.

6. Verify Calibration

Once the gauge is securely installed, verify that it’s reading correctly by comparing it to the expected water pressure for your system. You may want to cross-check the pressure with another known accurate gauge to confirm that the A-115A is properly calibrated.

How do I read the pressure on the A-115A gauge?

 1. Locate the Dial: The A-115A gauge features a circular dial with markings for pressure measurements. The needle on the dial indicates the current pressure level.

2. Identify the Pressure Scale: The gauge will typically have a pressure scale marked in pounds per square inch (psi). The scale usually goes from 0 psi (at the far left) to 160 psi (at the far right), with intermediate markings for every 10 psi increment.

3. Read the Needle Position: The needle on the gauge points to the current pressure reading. To read the pressure, note where the needle points on the dial. For example, if the needle is between 40 and 50 psi, you can estimate the pressure to be around 45 psi.

4. Check for Accuracy: Make sure the needle is steady and not fluctuating. If the needle is bouncing or not stable, this could indicate an issue with the pressure system or the gauge itself.
