Step-by-Step Installation Guide
Installing a smart bidet toilet seat is easier than you think and typically takes 20-30 minutes. Follow these simple steps to get your bidet seat up and running.
🚽 Step 1: Remove the Existing Toilet Seat
✔ Locate the bolts holding the current toilet seat in place.
✔ Use a Phillips screwdriver to loosen and remove the bolts.
✔ Lift the old toilet seat and set it aside.
✔ Clean the mounting area to ensure a smooth installation.
📌 Tip: If the bolts are stuck, apply a few drops of penetrating oil to loosen them.
🔧 Step 2: Install the Mounting Plate
✔ Position the bidet seat’s mounting bracket over the toilet’s bolt holes.
✔ Insert the included bolts and tighten them loosely at first.
✔ Adjust the bracket position to align the bidet seat properly.
✔ Fully tighten the bolts with a screwdriver to secure the plate.
📌 Tip: Do not overtighten the bolts, as this may cause cracking or misalignment.
🚰 Step 3: Connect the Water Supply
✔ Turn off the toilet’s water supply valve.
✔ Flush the toilet to empty the water tank.
✔ Disconnect the existing water hose from the toilet tank.
✔ Attach the T-Valve (included in the bidet kit) to the toilet’s water inlet.
✔ Connect the bidet’s water hose to the T-Valve’s side outlet.
✔ Reconnect the main water hose to the bottom of the T-Valve.
📌 Tip: Use plumber’s tape (Teflon tape) on the threads of the T-Valve to prevent leaks.
🔌 Step 4: Connect to Power (For Electric Models)
✔ Plug the bidet power cord into a GFCI outlet near the toilet.
✔ If no outlet is available, you may need an extension cord or professional electrical installation.
📌 Tip: For non-electric bidet seats, skip this step—these models operate using only water pressure.
✅ Step 5: Test the Bidet Seat
✔ Turn the water supply back on and check for leaks.
✔ Sit on the seat and press the “Bidet” or “Wash” button to activate the spray.
✔ Adjust water pressure, temperature, and spray position as needed.
✔ If your model has an air dryer, test the drying function.
📌 Tip: If the bidet nozzle isn’t spraying, ensure the water valve is fully open and all connections are tight.
Troubleshooting Common Installation Problems
Even though installing a smart bidet toilet seat is usually simple, you may run into minor issues. Here’s how to fix common installation problems and get your bidet seat working perfectly.
🚨 1. Water Leaking at the T-Valve Connection
✔ Cause: Loose connection or missing plumber’s tape (Teflon tape).
✔ Solution:
- Turn off the water supply and disconnect the T-Valve.
- Wrap plumber’s tape around the threaded connections.
- Reattach the T-Valve and tighten it securely with a wrench.
- Turn the water back on and check for leaks.
📌 Tip: If the leak continues, ensure that the rubber washers inside the T-Valve are in place.
💧 2. The Bidet Nozzle Isn’t Spraying Water
✔ Cause: The water supply valve is turned off or the bidet settings need adjustment.
✔ Solution:
- Check if the main water valve is fully open.
- Make sure the T-Valve is properly connected.
- Test the bidet function using the remote control or side panel.
- If the bidet still doesn’t spray, try a nozzle cleaning function (available on most models).
📌 Tip: If you installed a non-electric bidet seat, check that your home’s water pressure is strong enough to activate the nozzle.
🔌 3. The Bidet Seat Won’t Turn On (Electric Models)
✔ Cause: No power supply or the GFCI outlet is switched off.
✔ Solution:
- Make sure the bidet is plugged into a working GFCI outlet.
- Check if the outlet has a reset button and press it.
- Try a different power outlet or use an extension cord for testing.
- If the bidet still doesn’t turn on, check the power cord for damage.
📌 Tip: Some bidet seats won’t power on unless they detect a person sitting on them—test while seated.
💨 4. Weak Water Pressure from the Nozzle
✔ Cause: Low household water pressure or incorrect bidet settings.
✔ Solution:
- Increase the water pressure setting on the remote or control panel.
- Check if there is a water flow restrictor in the T-Valve—removing it may improve pressure.
- If the entire household has low water pressure, consider installing a water pressure booster.
📌 Tip: If you notice uneven spray patterns, the nozzle may need cleaning—use warm water and a soft cloth.
