Why Do Bidets Leak: The Common Causes

Here are the common causes of bidet leaks:

  • Loose valve
  • Dirty filter

  • Defective nozzle
  • Broken hose

  • T-valve
  • Water supply hose

How to Fix Leaking Bidets: The Situations and Steps

Now that you have the tools ready, you might have found a bit of courage and confidence. Let us then move on to the hard part. Below are specific situations with the corresponding steps that you can do.

Loose Valve

We are talking about two valves here. The first valve is the main valve that connects to the wall or your faucet. The other valve is the t-valve that is connected to your toilet, and this is the valve that houses the hose of the bidet.

  • Step one: Turn off the water supply valve.
  • Step two: Check the t-valve if it is loose. Even if it is not loose, secure it with the use of a wrench.
  • Step three: Open the water valve and try to use the bidet. If there are still leaks, you have to turn off the water valve again.
  • Step four: Check the main valve if it is loose, and secure it with the use of a wrench.
  • Step five: Open the water valve again and check for leaks.

Dirty Filter

Bidets that come with filters are the toilet seat bidets and underside bidets. The filters are usually located near the controls. If it is too dirty or there is something that blocks the flow of water, it will cause a leak.

  • Step one: Turn off the water supply valve.
  • Step two: Open the filter cage of the bidet using a screwdriver.
  • Step three: Dump the contents of the filter and wash it under running water. Do not use any form of cleaning agents.
  • Step Four: Put back the filter.
  • Step Five: Open the water supply valve and check if there are still leaks.

Water Overflow in Tank

This usually happens due to too much water pressure, not only in the bidet and toilet, but also the pressure coming from the main water supply.

  • Step one: Check if the water supply valve is completely open. If it is, try to turn it midway where it is half-closed and half-opened.
  • Step two: Check if the bidet still leaks.
  • Step three: If it still leaks, adjust the main water supply valve and also set it midway.
  • Step four: Check if the bidet still leaks.

Defective Nozzle

It is normal for a nozzle to break down. Maybe the stopper inside it became loose or got destroyed that even though your bidet is off, there is still a bit of water leaking from it.

For handheld bidets:

  • Step one: Turn off the water supply valve.
  • Step two: Remove the main nozzle from the hose by twisting it with your hands.
  • Step three: Replace the nozzle and attach it back to the hose.
  • Step four: Open the water supply valve and check if there are still leaks.
  • Step five: If there are leaks, remove the nozzle again and put a decent amount of Teflon tape in between the nozzle and the tip of the hose.
  • Step six: Attach the nozzle again and check if there are still leaks.

For toilet seat bidets or underside bidets:

  • Step one: Turn off the water supply valve
  • Step two: Remove the toilet seat bidet or the toilet seat by rotating the knobs on each side of the seat.
  • Step three: Check if the nozzle is broken. If it is broken, replace the nozzle; if it does not sit well with the body of the bidet, put some Teflon tape around it.
  • Step four: Put it back on the toilet seat.
  • Step five: Turn on the water supply valve and check if there are still leaks.

Broken Hose

This is the most straightforward to do because you are sure that the leaks will stop after you replace the hose. Further, it is the easiest cause to pinpoint when you assess your bidet. We will focus on one hose here, and that is the main hose of the bidet.

  • Step one: Turn off the water supply valve
  • Step two: Remove the hose from the nozzle by twisting it with your hand.
  • Step three: Remove the other end of the hose that is connected to the t-valve by using a wrench.
  • Step four: Replace with another hose.
  • Step five: Attach the hose to the t-valve and the nozzle.
  • Step six: Open the water supply valve and check if it still leaks.


There you have it, the different steps for fixing the different causes of a bidet leak. Remember that when doing those steps, exercise caution and always remember to turn off the water supply valve.

Again, if these steps prove to not be the solution to the leak, do consult a professional. In the meantime, you should hold your fort and manage that annoying leak.
