Water pressure issues anywhere in your home can become very inconvenient quickly. Pressure issues in your toilet can prove especially troublesome and render the toilet nearly nonfunctional. Before you call in a plumber for assistance, there are a few quick checks and fixes you can make to try and fix the toilet water pressure issues yourself.
Here are two potential quick fixes for water pressure issues isolated to your toilet. If you don't feel comfortable making the fixes yourself, call a residential plumbing services company for help.
Standard Toilet: Check the Toilet Fill Valve and Flapper
Is the low water pressure confined to one toilet? First, check that the shut-off valve behind the toilet is fully in the open position. A partially closed valve will still let through water but not at the full pressure.
Next, check to see if you are having a problem with the fill valve assembly. Lift your toilet tank lid off and set it to the side. Look inside the tank and you should see a tall vertical tower. That's the main fill valve. One end connects to the back of your toilet flusher while the other side attaches to a float that bobs on the surface of the water and a stopper called the flapper that plugs a hole in the bottom of the tank.
Do you have low water pressure when you flush but the tank seems to be filling up to the proper level? The chain that connects your flapper to the fill valve might be too short. When the flusher moves the fill valve arm to pull the flapper's chain, the flapper is only partially lifting up to allow tank water to refill the toilet bowl. Purchase a new flapper with a longer chain and install it in your toilet.
If the toilet bowl is refilling fine but the tank isn't filling to the proper level, you likely need to replace your float. The float typically looks like a plastic balloon that is raised as the water fills the tank. The float is supposed to tell the tank water where to stop filling, but a broken float can cause the filling to stop prematurely. Purchase and install a new float to fix the problem.
Pressure-Assisted Toilet: Clean Screen and Actuator
Pressure-assisted toilets have a different interior setup than standard toilet models. If you have water pressure problems with a pressure-assisted toilet, there's a good chance it is a problem with your home's plumbing that needs the assistance of a plumber. But there are a couple of quick maintenance checks you can try before you call.
The first check involves a screen that is located between the water supply line connecting to the bottom of the tank and the tank itself. Turn off the water using the shut-off valve and flush out all of the water in the tank. Put a bucket directly under the supply line. Use pliers to twist the supply line free of the tank and drop the line down into the bucket to drain out any remaining water hanging around in the line.
Now check the screen that is on the end of the line. Is it cluttered with debris? Remove the screen and hold it under a kitchen rink faucet to remove the debris or mineral buildups. Reattach the screen firmly, hook the line back to the tank, and turn the water back on.
If the screen cleaning didn't impact the pressure, you can check for any debris stuck under the actuator. You can easily locate the actuator by removing the tank lid and then flushing. See that part that just popped up then went down? That's the flush rod on the actuator.
Flush again while standing close to the actuator. As the actuator raises up, use an old toothbrush to knock free any debris stuck under the actuator before it falls down again. If you need any assistance with these steps, visit DiRosato Plumbing and Heating.
