4. Setup jeung Instalasi
Proper installation of the Watts LF25AUB-Z3 valve is crucial for optimal performance and longevity. It is recommended that installation be performed by a qualified plumber or technician.
4.1 Daptar pariksa Pra-Pamasangan
- Ensure the main water supply is turned off before beginning installation.
- Verify that the installation location is accessible for future maintenance.
- Confirm the valve size (1 inch) matches your plumbing system requirements.
- Gather necessary tools: pipe wrenches, thread sealant (Teflon tape or pipe dope), and a pressure gauge for verification.
4.2 Léngkah-léngkah Instalasi
- Nyiapkeun pipa: Cut a section of the main water line where the valve is to be installed. Ensure the cut ends are clean and free of burrs.
- Orient the Valve: The valve has an arrow indicating the direction of water flow. Ensure the arrow points in the direction of water flow from the main supply into your home. The NPT female union inlet connects to the incoming water supply, and the NPT female outlet connects to the household plumbing.
- Larapkeun Thread Sealant: Apply an appropriate thread sealant (e.g., Teflon tape or pipe dope) to the male threads of the pipes that will connect to the valve's union and outlet.
- Connect the Valve: Securely connect the valve to the plumbing lines. Use pipe wrenches to tighten connections, but do not overtighten to avoid damaging the valve or pipes.
- Pariksa bocor: Slowly turn on the main water supply and carefully inspect all connections for leaks. Tighten any leaking connections as needed.
- Verify Pressure: Use a pressure gauge connected to a nearby hose bib or test port to verify the outlet pressure. The valve comes factory preset to 50 psi.

5. Parentah Operasi
The Watts LF25AUB-Z3 valve is designed to maintain a consistent outlet pressure. The factory setting is typically 50 psi, but it can be adjusted within its specified range.
5.1 Adjusting Outlet Pressure
- Locate Adjustment Screw: The pressure adjustment screw is located at the top of the valve, typically covered by a cap or a locknut.
- Loosen Locknut (if present): If there is a locknut, loosen it before making adjustments.
- Saluyukeun tekanan:
- Ka naékkeun the outlet pressure, turn the adjustment screw clockwise.
- Ka ngurangan the outlet pressure, turn the adjustment screw counter-clockwise.
- Monitor Tekanan: Use a reliable pressure gauge connected to a downstream hose bib or test port to accurately monitor the pressure as you adjust.
- Tighten Locknut: Once the desired pressure is set (within the 25-75 psi range), tighten the locknut (if present) to secure the setting.
Note: Avoid setting the pressure too high, as excessive pressure can damage household plumbing and appliances. Most residential plumbing is designed for a maximum of 80 psi.

6. Pangropéa
Regular maintenance ensures the continued optimal performance and extends the lifespan of your Watts LF25AUB-Z3 valve.
6.1 Cék rutin
- Pariksa tekanan taunan: Periodically check your household water pressure using a pressure gauge to ensure the valve is maintaining the desired setting.
- Inspeksi bocor: Visually inspect the valve and surrounding connections for any signs of leaks.
- Pembersihan Saringan: The valve includes a removable integral stainless steel strainer. If you notice a significant drop in water pressure or flow, the strainer may be clogged and require cleaning. Consult a professional for this procedure if you are unsure.
6.2 Palayanan
The valve is designed for easy in-line serviceability, featuring a replaceable seat module. For internal servicing or replacement of components, it is highly recommended to contact a certified plumbing professional. Attempting repairs without proper knowledge and tools can lead to damage or improper function.
