How to Increase Bidet Water Pressure?

A few of the options that can be helpful in increasing the bidet water pressure would include opening the shut off valve, checking water pressure regulator, change the spray modes if available and cleaning the nozzles. 

We will check out different options to help you in how to increase bidet water pressure. 

Fix 1: Fully open the toilet shutoff valve 

The shutoff valve near the toilet may not be opened fully. Normally, it is set to a lower setting when the bidet is installed. Make sure that it is opened fully. Some people may have issues with the heavy pressure at the bidet nozzles and they would perhaps want to partially close the shutoff valve.

The shut off valve might also have been closed to stop the water from going berserk when installing the bidet. It is advisable to check if the toilet shut off valve is open before trying out other fixes. 

Fix 2: Check for the leaks in the water supply

If you notice the low pressure in the bidet alone and not in other appliances and connections, it may be due to the leakage in the water supply leading to the bidet nozzle. Of course, you would notice the leakage if there is one, but in any case, it is a good idea to check the same.

In some cases, the leakage in the water supply may be hidden in the vanity. It may also be underneath a sink and possibly go unnoticed. We would advise checking out the leakage in your water supply. 

Fix 3: Check if the mesh filter needs cleaning

The mesh of the bidets can get blocked. By mesh filter we mean the small filter that sits on the bidet inlet and cleans the incoming water from the hose. If you notice the weak pressure in the bidet but if all the other appliances are working fine, you can conclude that it can be due to the clogged filter. 

Check if the mesh water filter needs any sort of cleaning. In some cases, the mesh filter may need replacement. You can remove the hose attached to the bidet and place it under the running water to clean the filter. 

Fix 4: Check for additional spray modes 

It is possible that the default spray mode may not be working fine for you. If your bidet has multiple spray modes, it would be advisable to check the othr spray modes. The additional spray modes would be a great option because you would not need to buy a new bidet. 

Some of the electronic bidets come with extra song bidets that are designed to offer a thorough and complete cleaning. If you are someone like me who has a bizarre eating habit, you would perhaps need a strong cleansing. 

Fix 5: Replace the external filter 

Most of people use and prefer the external filter on their bidet. When the filter gets blocked due to dirt. The dirt may reduce the water flow and thus reduce the water pressure. This can also happen due to the hard water. 

You can try and clean the bidet filter. It would be a good idea to replace the bidet filter once every six months. It may also be based on the area that you live in. A location that receives the hard water can lead to a faster blocking. 

Fix 6: Check if the T valve is open fully

The T valve is the valve that connects the bidet to the main water supply of the toilet. This valve can be adjusted to allow for more water intake. The T valve may be located in different places depending on the brand and model that you may be using.

Once you have found the T valve, you can simply check if it is open. If not, open the valve fully. This will help allow more water intake. It should be the best means to help you increase the water pressure. 

Fix 7: Check the water pressure in your home 

Another possibility that the bidet is not receiving a low pressure can be that the pressure in your home is too low. There can be a few ways that cause the low pressure in your home. In our experience, this is one of the most common issues that we observed for the low pressure on bidet. 

Some of the reasons can be that: 


  • Bad pressure regulator: The pressure regulator in your home can be broken. This will result in both high and low water pressure 
  • Clogged pipes: Clogged pipes can one of the causes for the low pressure. You can get in touch with the plumbing professional to help you in fixing the issue. 
  • Old pipes: Pipes can get corroded over time. Corroded pipes can lower the water pressure.

Fix 8: Check The Water Supply Temp and Power Source

If you have an electric bidet, some of them may not support the high pressure in case the water supply temperature is below a certain threshold level. Make sure that the water supply temp and power source are proper. 

If the temperature is too cold, you may not get enough water on your seat. If the temperature is too hot, you may get you’re the seat damaged. The ideal temperature would be 86-104 degrees Fahrenheit. 

Fix 9: Ensure that the right pressure setting is selected 

Make sure that the water pressure setting is not set to the lowest level. It is quite common in the case of electric bidets. The side panels and remote controls are a little complicated and that is why you need to be careful with the settings and ensure it is set to a proper level. 

Some bidets may have a simple remote and panel. However, you would have three to five pressure settings to choose from. You can experiment and finalise a setting that you are comfortable with. 

Fix 10: Check the output pressure for your bidet 

If you find none of the options as outlined above work for you, you can perhaps need to check the further settings for increasing the water pressure in your bidet. If you find the pressure is too low, it would be advisable to check if the issue is with the bidet itself. 

Fix 11: Buy A Non-electric Bidet

Non electric bidet is more likely to have high pressure when compared to the electric bidets. The type of bidet that you choose would determine the pressure of the bidet. If you are going with an electric bidet, make sure that you have chosen the right one and gone through the manual for understanding them better. 

Electric bidets do come with several features and make them a great bidet in itself, but they do come with a weak water flow or lower water pressure. Of course, the pressure on the bidet is great enough, but some of us want a really high pressure in their bidets. In such a case or such a scenario, where we would recommend using a non electric bidet than opting for the electric bidets.

How Much Water Does a Bidet Use?

An average bidet will use around 0.125 gallons of water per use. The electric and non-electric bidets say that they take around a maximum of 0.16 gallons to get clean from a bidet. The exact amount would be dependent on the water flow rate and how long you would be running the bidet for per use. 

In any case, the bidet will use only a minuscule amount of water when you compare it to the amount needed for the toilet soap.  Given the fact that a toilet roll take 37 gallons of water should stand a proof to indicate how low an amount of water does a bidet use.
