How To Find The Source Of Low-Water Pressure In Your Bathroom Faucet
If your bathroom faucet has started releasing less water even when you have your handles turned all the way, the problem could be in a number of places under your sink or in the sink fixture itself. Broken parts, parts that have been moved and buildups of sediment can cause your water pressure to slowly decrease.
Whether you have the problem in your hot water, your cold water or both, basic troubleshooting should lead you to the source -- and fixing it isn't much harder:
Water Pressure Is Low On Only One Side
If water pressure is lower on one side than the other, you'll already be able to narrow down the problem to a few locations: the faucet supply tube or the faucet handle.
First, check the faucet supply tube for the side with the low water pressure. Shut off the valve, then unscrew the tube from the faucet. Place the faucet end of the tube into an empty bucket, then open the valve again. If your water pressure is fine, the problem is somewhere in your faucet. If not, there's probably a clog in the tube itself.
In either case, you can attempt to use a drain cleaning product to clear any clogs. If you want to use the cleaner on your faucet, you'll have to unhook your faucet first so you can pour the cleaner into the handle; remember to have the handle in the on position so the cleaner can flow through.
If this doesn't work, you may need to replace the part. Replacing a tube is easy enough, but replacing a whole faucet fixture is a little more pricey. If the problem is in the faucet itself and a drain cleaner doesn't fix it, it's possible that there is a broken part inside the handle preventing water from passing, and cleaners won't be able to break it down.
Water Pressure Is Low On Both Sides
Low water pressure on both sides is usually more likely to be caused by a problem in the faucet, as its unlikely that both supply tubes will have clogged at the same time. In this case, unscrew the aerator, which is the part of your faucet where the water comes out. An aerator limits how much water comes out of your faucet with a small screen, and this screen can occasionally get clogged. Clean off the aerator by tapping it gently on your sink, running water over it with the top facing down or by blowing into it.
While it's unlikely that both supply tubes have been clogged, there could be a chance that both shutoff valves were bumped. If you recently moved things around under your sink, it could have bumped the valves partially closed. Do a quick check to make sure they're both fully open. While you're at it, make sure the flex lines aren't bent, as this can restrict water flow.
