How to replace a water filter cartridge on your home water filtering system. This article covers how to alter both filters on a Aquasana AQ4000 filter system. Some of this selective information may be helpful with any brand of filter system. Unpack the alternate filter kit and check the contents. You ought to have 2 substitute water filter cartridges, A and a B. Two alternate O-rings. If the O-rings are not flat lay them out and see if they will flatten out on their own this may take over night. If this does not work, put a book on them over night. The reason is if the O-rings are bowed from shipping makes then harder to make a good seal. The primary step is to lay your home water filtering scheme on it is side. You may see on the filter caps are labeled A and B. Also arrows that indicate which way to turn to loosen each cap. Turn filter cap A to the right to unscrew or the direction the arrow points. Filter cap B ought to unscrew to the left or the direction of the arrow. They must only be hand tight. If they are too tight to remove by hand use the handles of a pliers to give you a little extra leverage. Be careful not to do any harm to the inlet or outlet water lines. Water filter cartridge A will be the most difficult to remove. The seal on the top of the filter holds the cartridge in place. There is not sufficient room in the filter housing to get a hold of it. I find it easy to use a pair of pliers to get a hold of the filter and twist and pull to it out. Water filter cartridge B will be attached to the filter cap. Simply twist and pull the two apart. I lay the filters at each side of the filter housing. This helps to keep track of which filter is A and B. Remove both o-rings make sure the grove where they sit in is clean. Now install the two new O-rings. Put a little amount of feed grade silicone based lubricant on the exposed area of each O- ring. This helps when installing the filter caps. The oil lets the caps slide easy on the rubber, which will make them seal easier. Installing them arid may let them kink and dislodge resulting in a leak. Replacement water filter cartridge A is the white one. Install it in the A cartridge housing with the O-ring end in first. Putting a good deal of water on the rubber seal makes it slide in easier. Give it a push and turn until it is seated. The B alternate cartridge is the blue one. Install the O-ring end into the filter cap. In the same manner as the other filter. At this point, I check the O-ring to make sure they are still in place. Then go in front and install the B filter into the B housing. Screw the B cap until it is with resolute determination seated. Now check the other seal and install the A cap until it is with resolute determination seated. Keep the filter system on it is side, turn on the water and activate the diverter valve. Check around the cap threads for any signs of water. If there is a little leak, undertake tightening the cap a little more. If this does not seal the leak, then open up that cap and check the O-ring it may have came out of it is seat. Check to make sure it is not cut or damaged. If it is, the old O-ring might reseal. The other option is take one of the old seals to your local hardware store and match it up. The other step if none of these ideas work is to order a alternate seal. Now you may be reinstalled the cap as described above and check for any leaks. If you do not see, any leaks set the AQ-4000 up right and leave the water run for in regards to 2-3 minutes until the water runs clear. The water at firstborn may come out cloudy or even have a black color, this is normal. Carbon dust is being cleaned out of the new filter cartridges. I save the water that applied to flush out the filter system. Houseplants like the water, or put it on plants out side. To keep track of when it will be time to reinstall your next set of water filters. Write the next substitute date on a piece of tape and put it on the filter. This helps to keep track of time. They ought to be substituted each 6 months or 500 gallons on your home water filtering system. |
