It is crucial to check your backflow preventer regularly to ensure it is functioning properly. Backflow preventers help protect your home’s water supply from contamination by preventing water from flowing back into the main water line. Here’s how to check your backflow preventer:
## Step-by-Step Instructions:
1. **Gather Tools**: You’ll need a pressure gauge, screwdriver, hose bib, and a bucket.
2. **Turn Off Water Supply**: Shut off the water supply to the backflow preventer using the shut-off valve.
3. **Attach the Pressure Gauge**: Connect the pressure gauge to the hose bib located downstream of the backflow preventer.
4. **Turn on the Water Supply**: Slowly turn on the water supply and allow water to flow through the system.
5. **Close the Hose Bib**: Once the gauge reaches its maximum pressure, close the hose bib.
6. **Check the Pressure**: Read the pressure gauge. The pressure should drop slowly as the water drains back through the backflow preventer.
7. **Look for Leaks**: Inspect the backflow preventer for any leaks or water seepage.
8. **Reset the Backflow Preventer**: If the pressure drop is too fast or you find leaks, the backflow preventer may need to be reset. Follow the manufacturer’s instructions for resetting the device.
9. **Tighten Connections**: If you notice any loose connections, tighten them using a screwdriver.
