How to take out aerator for cleaning

If it works after you removed the aerator then its possible you had dirt in the lines and the aerator is partly plugged. Take apart and clean the screen.

It sounds like either your aerator is clogged, or someone has removed the metal screens to use for the combustion of herbal products. If nothing is missing from the aerator, it is probably clogged with white scale. Simply take a baggie filled with vinegar and place it over the aerator fastening it in place with a rubber band. After a couple of hours, remove and scrub with old toothbrush. If this doesn't work, remove the aerator and replace it. It screws right off.

aerator always screw off typically counter clock wise (lefty loosy), but remember the aerator is "upside-down" as you look at it on the faucet arm. There are two types, male threaded and female threaded. Both unscrew from the faucet arm the same. There are at least four different sizes so take the old you with you when you go to replace it. Most times the threads are gunked up by lime and hard water deposits which means a pair of pliers or channel locks along with gentle rotation of the aerator cap will be needed to loosen the threads. Be aware that a washer may tend to stick in the faucet arm opening after you remove the aerator. Stick your pinky into the faucet spout opening and fell if there is a black rubber washer. Replace with a new one in reverse.

It will have an aerator on the end of the faucet that has a screen. Sometimes these can be removed by hand carefully unscrewing. Others require an aerator removal tool (cheap). Either way, remove the aerator taking care not to allow it to separate into parts. Once removed, you can then dis-assemble noting the order in which you did so. Clean screens and re-assemble.

Either remove the plastic aerator and soak it in vinegar for a minimum of 30 minutes and blow high water pressure (garden hose) to clean it out or call ROHL Customer Service 800.777.9762 fro a replacement aerator.

You need an aerator wrench, Pfister part number 941-031. Several vendors on the web carry this part.

If you have full pressure on the cold water side and low pressure on the hot side then you well need to remove and clean or replace the cartridge for the hot side. If you have low water pressure on both sides try removing the aerator and cleaning it.
If you need to replace the cartridge on the hot side do both sides while you at it.
Whenever you work on any faucet before you turn the water on remove the aerator and run the water for a few seconds then replace the aerator.

Yes, the aerator (where the water comes out) can be unscrewed and removed from the faucet. I remove these and clean them out on a regular basis. If the aerator won't unscrew by hand, place a washcloth over the aerator (to prevent scratching) and carefully turn it with a pair of pliers. (Screw direction to loosen: Looking down on faucet, with pliers to the right-hand side, pull them toward you.) Make sure the rubber washer is properly placed in the top of the aerator after you have cleaned it out and you go to screw it back on. You normally don't need pliers to put it back on, as these are meant to be screwed on hand-tight. There might be several little parts inside the aerator to take apart and clean out, so be very careful to put these parts back together the same way they came apart. I find a toothpick is often useful to clean these out, as well as a cup of water to rinse them in.

Remove and clean the Price Pfister aerator. Turn the water on after you remove the aerator and check the flow-rate. Many new Lavatory and kitchen faucets are now equipped with Eco friendly water saver aerators. if the flow is normal without the aerator, the faucet is OK. if you want more water flow from your lavatory faucet, you will need to buy one of the old style high flow aerators from your hardware store. If you remove the aerator and still get low pressure from both hot and cold faucets, you may need to replace the faucet. Call the Price Pfister warranty phone number that came with your faucet.

Remove the aerator at the end of the spout. It will unscrew and once off it will have a dime sized restricter in it that can be removed this restrict's the water down to about 1.6 gpm to save water.
It will either be plastic or metal and about the size of a dime with a small holw in it to let water pass by maybe 1/8" hole just remove it and put aerator back together.

Clean aerator screen out before you put it back together.
