5. Орнотуу
Proper installation is crucial for the optimal performance and longevity of your pressure regulator valve. It is recommended that installation be performed by a licensed plumber.
Орнотуу кадамдары:
- Суу менен камсыздоону өчүрүү: Locate the main water shut-off valve for your property and turn it off.
- Депрессуризация системасы: Open a faucet at the lowest point in your system to drain water and relieve pressure.
- Жайгашкан жерди тандоо: Install the regulator on the main water supply line after the main shut-off valve and before any branch lines. Ensure there is sufficient space for future maintenance.
- Orient Valve: The valve has an arrow indicating the direction of water flow. Install the valve so the arrow points in the direction of water flow into your property.
- Байланыштарды түзүү: Use appropriate plumbing practices to connect the 1-inch FNPT Union x FNPT ends of the regulator to your plumbing system. Apply thread sealant (e.g., PTFE tape or pipe dope) to all threaded connections. Tighten securely but do not overtighten.
- Install Pressure Gauge (Optional but Recommended): Install a pressure gauge downstream of the regulator to monitor the regulated pressure.
- Суу менен камсыздоону калыбына келтирүү: Slowly open the main water shut-off valve. Check for leaks at all connections.
- Абаны тазалоо: Open faucets throughout the property to purge air from the system until water flows smoothly.
