How to install a bidet sprayer?

2026-07-02
Tools & parts you need

Bidet sprayer set, T-adapter (dual-outlet angle stop), two stainless supply hoses, PTFE tape, adjustable wrench, towel, bucket.

Step 1: Cut off the water supply

Turn off the angle valve supplying the toilet. Flush the toilet to empty most water from the tank. Have a bucket ready to catch leftover water when you disconnect the hose.

Step 2: Remove the original toilet supply hose

Unscrew the hose that connects the wall water outlet to the bottom of the toilet tank. Drain remaining water into the bucket.

Step 3: Wrap PTFE tape on the T-adapter thread

Wind PTFE tape clockwise around the male thread of the T-adapter for better sealing and to prevent water leaks. Do 10–15 layers of tape.

Step 4: Mount the T-adapter

Screw the T-adapter onto the wall water outlet. Do not over-tighten to avoid cracking the thread. The T-adapter has two outlets: one for the toilet tank, one for the bidet sprayer.

Step 5: Connect the hoses

Short hose: Link one outlet of the T-adapter to the toilet tank inlet.

Long sprayer hose: Attach the other outlet to the base of the handheld bidet sprayer.

Step 6: Install the sprayer holder

Stick or drill the mounting bracket on the wall next to the toilet at a comfortable height for easy access. Hang the sprayer on the bracket when not in use.

Step 7: Test for water leaks

Slowly open the angle valve to restore water flow. Let water run for 5 minutes and check all joints (T-adapter, hose ends, sprayer base).
