        "content": "Here\u2019s how to correctly install a Mainstay 1.5 GPM chrome aerator \u2014 including whether you need to use one or both of the rubber gaskets (washers) that sometimes come with these aerators.\n\n---\n\n### What you\u2019ll need\n\n- Mainstay 1.5 GPM chrome aerator  \n- 1 or 2 rubber washers (often included)  \n- Towel or rag (to protect finishes)  \n- Possibly pliers or a small wrench (with protective layer)  \n\n---\n\n### Step-by-Step Installation\n\n1. **Remove the old aerator**  \n   - Turn it counter-clockwise to unscrew. If it's hard to turn, wrap it in a towel and use pliers gently, to avoid damaging the finish.  \n\n2. **Clean the faucet threads**  \n   - Wipe off any mineral deposits, old sealant, and grime. Clean threads help ensure a watertight seal.  \n\n3. **Determine thread type**  \n   - *Female/Internal threads:* These are threads inside the faucet spout.  \n   - *Male/External threads:* These are threads outside the spout where the aerator screws on.  \n\n4. **Insert washers (rubber gaskets)**  \n   - Depending on your faucet\u2019s thread type, you\u2019ll use one or two washers:  \n     \u2022 **External (male) threads:** Use *one* rubber washer on top of the aerator body.  \n     \u2022 **Internal (female) threads:** Use *two* rubber washers (a \u201cthinner\u201d one and a \u201cthicker\u201d one) stacked inside the aerator body.  \n   - These washers help seal the connection and prevent leaks. ([minnesotapower.blob.core.windows.net](https://minnesotapower.blob.core.windows.net/content/Content/Documents/ProgramsRebates/Kits/WaterSavingKit-Installation-Instructions.pdf?utm_source=openai))  \n\n5. **Attach the aerator**  \n   - Screw the aerator onto the faucet by turning it **clockwise**.  \n   - Start by hand to avoid cross-threading. Tighten snugly. If it leaks after turning on the water, you may need to gently tighten more with pliers, using a cloth to protect the finish.  \n\n6. **Check for leaks**  \n   - Turn on the water slowly. If water leaks around the edges, tighten slightly more.  \n\n---\n\n### FAQ: Do Both Gaskets Always Need to Be Used?\n\n- **Not always.** Use both **only** if your faucet has internal (female) threads.  \n- If the faucet has external (male) threads, use just the thinner washer. Using more than necessary can cause build-up issues or make sealing harder.
