Question 1

going on vacation for a month, what should i do with my aquasana under sink filter?

Accepted Answer

DIAGNOSIS: For a month-long absence, you should winterize the system to prevent issues. FIX: Follow the long-term absence procedure. Shut off the water supply to the filter. Drain all water from the system and the housing. Remove the filters to prevent water stagnation inside them. IF THAT DIDN'T WORK: For model-specific guidance, contact Aquasana support at 866-662-6885 before you leave. HEADS UP: Stagnant water in the system for a month is not ideal. Taking these steps ensures you return to clean, fresh-tasting water.

Question 2

replaced filters on my aquasana aq-6300m but the red light is still on

Accepted Answer

DIAGNOSIS: You didn't replace the battery. The system uses the battery to power the indicator. FIX: Replace the battery tray. Open the battery compartment on the system manifold. Remove the old battery tray and dispose of it properly. Insert the new battery tray that came with your filter replacement cartridges. When inserted correctly, the system will beep five times and the LED will blink red. This resets the indicator. IF THAT DIDN'T WORK: If the red light persists after a new battery, the filter housings are likely not fully locked. Remove and reattach each one, ensuring you feel the 'click' and they are aligned correctly (Black, White, Yellow for the AQ-6300M). HEADS UP: The battery must be replaced every time you replace the filters. A new one is included with the filter cartridges. Also, remember to flush the system for 10 minutes after filter replacement before drinking the water.

Question 3

how do i know if i put the filters in right on my aquasana? it doesn't feel secure

Accepted Answer

DIAGNOSIS: They're not locked. Proper installation requires alignment and a tactile click. FIX: Re-seat them correctly. Remove the filter housing by turning it to the left and pulling straight down. Do not angle it. Before reattaching, check the arrow on the top cap of the filter. It must line up with the center tick mark on the system manifold. Push the housing up onto the manifold while turning it to the right. Continue turning until you feel a distinct 'click'. This is the lock engaging. Ensure the housing is not on an angle. It must sit flush and straight. IF THAT DIDN'T WORK: If you cannot achieve the click, inspect the o-ring on the housing for damage or misalignment. A damaged o-ring can prevent proper seating. Gently reposition it if it's out of place. HEADS UP: Incorrect placement, especially at an angle, will damage the o-ring and cause leaks. All housings must be locked in place as indicated by their color-coded positions on the system, such as Red for the first filter and Yellow for the second on an AQ-6200.

Question 4

my aquasana water pressure is really slow from the new faucet

Accepted Answer

DIAGNOSIS: Low pressure is typically caused by kinked tubing, an unflushed system, or incorrect filter installation. FIX: Systematic check. Inspect all plastic tubing under the sink. Ensure there are no kinks, crimps, loops, or folds. Cut away excess tubing if it's creating a tight bend. Verify the tubing is fully inserted—1 inch minimum—into all inlets and outlets on the manifold. Confirm the filters are installed correctly. For the AQ-6300M, the sequence is Black, White, Yellow. Wrong order can restrict flow. Flush the system for 10 minutes if you haven't already. Initial carbon fines can temporarily reduce flow. IF THAT DIDN'T WORK: Check your home's water pressure. The system requires an operating pressure between 20 and 80 psi. Pressure below 20 psi will result in very slow flow. HEADS UP: The rated service flow is 0.5 gallons per minute for the AQ-6200/AQ-6300 and 0.72 gpm for the AQ-6300M Max Flow. It will not match the pressure of your main kitchen faucet.

Question 5

can i hook up my fridge to my aquasana claryum 3-stage filter?

Accepted Answer

DIAGNOSIS: Yeah, you can, but there are some caveats. It's not the primary design. FIX: You have two basic options. Run a water line directly from the filtration system to the fridge. Use a tee fitting at the outlet line that goes to your dedicated faucet. You'll need a quick-connect fitting, which you can get at hardware stores. IF THAT DIDN'T WORK: The main issue you might hit is a drop in water pressure, especially if the fridge and faucet are running simultaneously. The system's service flow is 0.5 gpm for the AQ-6300, so it's not a high-pressure setup. HEADS UP: Aquasana doesn't provide detailed recommendations for fridge hookups since the systems aren't specifically designed for them. If you're not comfortable with plumbing, it's best to consult a professional.

Question 6

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

Accepted Answer

DIAGNOSIS: That's carbon fines from the new filters. You need to flush the system completely. FIX: Here's exactly what to do. First, ensure your installation is complete and there are no leaks. Turn on your dedicated Aquasana faucet. Let the water run continuously for a full 10 minutes. This flushes out the carbon particles used in manufacturing. IF THAT DIDN'T WORK: If the odd taste persists after a proper 10-minute flush, double-check that you removed all protective plastic from the filters during installation. Also, verify the filters are the correct color for their housing and are seated properly. HEADS UP: Do not drink the water during this initial 10-minute flush. After flushing, the water should taste clean. For absolute confirmation the system is working, you can use a water quality test kit.

Question 7

aquasana claryum filter leaking under my sink, help

Accepted Answer

DIAGNOSIS: The most common leak source is improperly seated tubing or filter housings. FIX: Check all connections. Turn off the cold water supply. Inspect the water supply line connections at the brass tee and the system manifold. Ensure all compression nuts are tight with a wrench. Check that the plastic tubing is inserted a full 1 inch into the inlets and outlets on the manifold. Wet the end of the tubing for easier insertion. Verify all filter housings are locked into the manifold correctly. They must be pushed up and turned to the right until they 'click'. They should not be on an angle. Inspect the o-rings on the filter housings for damage or misalignment. Gently move them into place if needed. Do not lubricate them. If the leak is at the faucet connection, check that the chrome nut is tightened (but not over-tightened) and the tubing is fully inserted. IF THAT DIDN'T WORK: If the leak is from a filter housing seam, the housing sump may be cracked or the o-ring is damaged. The housing sumps must be replaced every five years. Order a replacement at aquasana.com. HEADS UP: Do not use tools to tighten the filter housings—hand-tighten only. Over-tightening can damage the o-rings and cause leaks.

Question 8

my aquasana under sink water filter is beeping and the light is red, what does that mean?

Accepted Answer

DIAGNOSIS: The beeping and red indicator light mean your filters have reached capacity and need to be replaced. FIX: Replace the filters and the battery. Shut off the cold water valve under the sink. Release pressure by turning on the dedicated faucet. Wait for water to stop flowing. Unbox the new filter cartridges. Each filter is color-coded to match its housing. Remove each filter housing from the system manifold by turning it to the left and pulling down. Do not remove it at an angle. Over the sink, open each housing by turning the bottom left and the cap right. Pour out water, pull out the old filter, and inspect the o-ring. Press the new, color-correct filter into the top cap, then reconnect the bottom. Hand-tighten only. Reattach each housing to the manifold. Push up while turning right until you feel a 'click'. Ensure they are not on an angle and are aligned per your model's diagram. Open the battery compartment, remove the old battery tray, and insert the new one. The system will beep five times and blink red when it's correct. Slowly turn the water valve back on. Check for leaks, then flush the system for 10 minutes. Do not drink the flushed water. IF THAT DIDN'T WORK: If the beeping persists after a new battery and filters, the filter housings are likely not locked in place correctly. Remove and reattach them, ensuring a firm 'click' and proper alignment. HEADS UP: The system is designed to alert you at 95% capacity, which is about every 6 months. The filter housing sumps themselves need to be replaced every five years to prevent leaks from deterioration.
