just installed my aquasana and the water tastes weird, is that normal?

Diagnosis

This "weird" taste—often described as metallic, bitter, or slightly chemical—is almost always caused by carbon fines and air pockets trapped within the Claryum 3-Stage filter media. During the manufacturing and shipping process, the activated carbon blocks in the filter cartridges rub against each other, creating microscopic particles of carbon dust. When water first hits these blocks, it carries these fines into your drinking line, altering the flavor and occasionally causing the water to appear cloudy or grey.

Furthermore, the Max Flow system introduces a significant amount of air into the lines during the initial installation. As the water pushes through the three stages of filtration, these air bubbles can cause "sputtering" at the faucet and can temporarily affect the taste profile by altering the dissolved oxygen levels in the water. If you are tasting something specifically "plastic-like," it is likely the initial rinse-off of the internal food-grade tubing and the filter housings themselves, which requires a high-volume flush to clear.

How to Fix It

To properly prime the Claryum 3-Stage Max Flow system and eliminate the off-taste, follow this high-volume flushing sequence:

1. Verify Seal Integrity: Before opening the valve fully, wipe down all connection points with a dry paper towel to ensure there are no slow drips at the T-adapter or the filter head connections.
2. Slow Start: Slowly turn the cold water supply valve back on. Do not blast it open immediately; allow the pressure to build gradually to avoid "water hammer" within the filter housings.
3. The Primary Flush: Open the dedicated Aquasana faucet completely. Let the water run continuously. You will likely see "milky" water or hear sputtering; this is normal.
4. The 10-Gallon Rule: Do not rely on a timer alone. You need to flush approximately 10 gallons of water through the system. For most standard flow rates, this takes between 10 to 15 minutes of continuous running.
5. Purge the Air: While the water is running, gently wiggle the faucet spout to help trapped air bubbles escape the line.
6. Taste Test: Turn the faucet off for 30 seconds, then refill a clean glass. The water should now be crystal clear and tasteless.

If That Didn't Work

If the taste persists after a 15-minute flush, try these advanced troubleshooting steps:

• Check the Filter Orientation: Ensure the filters are seated perfectly flush in the head. If a filter is slightly cocked, water may "channel" through the side of the media rather than through the carbon block, leading to unfiltered water or concentrated carbon fines leaking into the stream. Remove the filters and re-seat them firmly.
• Inspect the Bypass Valve: If you installed the system with a bypass, ensure the valve is fully turned to the "filtered" position. A partially open bypass valve can mix unfiltered tap water with filtered water, creating a strange, inconsistent taste.
• Verify Cold Water Only: Confirm that you have connected the system strictly to the cold water line. If the T-adapter was installed on a line that receives any heat bleed from the hot water pipe, it can cause the carbon media to release trapped gases, resulting in a chemical taste.
• Check for "New Pipe" Contamination: If you replaced any plumbing sections or used new Teflon tape during installation, the taste may be coming from the plumbing itself. Run the dedicated faucet for another 20 minutes to clear any debris from the new connections.

Heads Up

Keep these maintenance tips in mind to ensure long-term water quality:

• Avoid Hot Water: Never connect the Claryum system to a hot water line. High temperatures can degrade the filter media and cause the carbon to release trapped impurities back into your drinking water.
• Filter Replacement Cycle: Set a calendar reminder for every 6 months. Once the Max Flow filters reach capacity, they can develop a "stale" taste as they stop effectively removing chlorine and VOCs.
• Sputter Warning: It is normal to experience a brief moment of sputtering (air bubbles) the first time you use the faucet after a long period of non-use or after a filter change.
• Leak Monitoring: Check the area under the sink weekly for the first month. A tiny drip at the filter head can lead to mold growth in the cabinet, which can eventually affect the smell of the water exiting the faucet.
