How to Install a Hand-Held Bidet Sprayer

How to install a bidet sprayer in 4 easy steps

Many people choose bidet sprayers because they are so simple to install. You’re just adding a valve to the water connection under your toilet! This diverts clean water before it reaches the toilet and sends it to the flexible bidet hose and bidet spray head. Installing a hand-held bidet sprayer is a quick DIY project, especially if you’re  not sure about bidets.

Once you’ve installed your hand-held bidet sprayer, don’t forget to learn  how to use it!

Before Installing Your Bidet Sprayer: Check your water supply line. That’s the water connection that runs between your toilet tank and the wall. Confirm that it’s a flexible hose (it probably is!). In rare cases, the water supply line is a rigid pipe. In this case you will need to replace it with a flexible hose to install the bidet sprayer.

Step 1: Turn Off the Water Supply

Turn OFF the water supply valve at the wall next to your toilet. Twist it clockwise as far as it will go. Flush the toilet and hold down the handle to completely empty the toilet tank.

Step 2: Connect the T-Valve

Unscrew the flexible water supply hose at the fill valve under your toilet tank (also called the ballcock valve) – not from the water supply valve at the wall.

Confirm that the flat rubber washer is inside the top of your bidet’s  T-valve (hint: the top of the T-valve is where the spinning nut is located). Screw the top of the T-valve onto the toilet’s fill valve where you just unscrewed the water supply hose.  Be careful not to over-tighten the connections.

Step 3: Connect the Hoses

Screw the toilet’s water supply hose to the bottom of the T-valve.

Connect one end of the bidet hose to the side of the T-valve. Screw the bidet sprayer head onto the other end of the bidet hose.

Step 4: Turn On the Water Supply & Mount the Sprayer

Turn the water supply valve back on. If you notice that any connection is loose or leaking, you may need to add some  plumber’s tape. If you’re leak-free, your hand-held bidet sprayer is installed and ready to use!

Holster Toilet Mount: Screw the holster onto the toilet tank clip. Lift up the toilet tank lid, slide the clip onto the side of the tank, and replace the lid.

Holster Wall Mount: Use the drywall screws and anchors to attach the holster to the wall.

Warm Water Hand-Held Bidets

Temperature control isn’t just for bidet seats! By installing a bidet  hot/cold mixing valve, you can have a hand held bidet sprayer with hot and cold water. This mixing valve connects to your faucet’s hot water line under your sink. You’ll use the valve’s handle to adjust the mix of cold and hot water for an adjustable temperature bidet spray.

Why is my Bidet Sprayer Leaking?

Outside of the installation process, bidet leaks happen when a hand held bidet isn’t turned off completely after every use. Stopping the water flow at the sprayer head is the first step to properly shutting off a hand held bidet, but turning off the bidet’s T-valve is the second – and most critical – step.

Bidet sprayers work in the same way as garden hoses but providing a jet spray for your toilet. When you’re done watering your plants with the garden hose nozzle, you release the handle, stopping the water. But the water isn’t turned off yet! You still need to turn the spigot off at the other end of the hose. If you don’t, the hose will leak or burst.

The same principle applies to a bidet sprayer. When you release the sprayer’s handle or trigger, you stop the spray jet… but there is still water pressure pushing against the bidet hose and sprayer head. Over time, this pressure causes damage, followed by leaking. If the damage is severe enough, it can even flood a bathroom. Shutting the water off completely at the T-valve relieves the pressure.

How Do You Fix a Leaking Bidet Sprayer?

If a leak has already started, you need to replace the leaking bidet part, because it’s damaged. Brondell offers both  replacement hoses and replacement sprayer heads. Once you’ve replaced the leaking bidet hose or leaking sprayer, you can ensure that your bidet will remain leak-free by shutting the T-valve off after every use!

If you’re not able to shut off your bidet's T-valve every time, we highly recommend switching to a different style of bidet. Brondell has plenty of  bidet attachments and seats that don’t require a T-valve shut off, but will still give you that great bidet clean!
