The toilet is of a standard design, with the seat cover down, and it is accompanied by a toilet brush holder to its right, which matches the toilet in color. A toilet paper holder is mounted on the wall to the left of the toilet, with a roll of toilet paper hanging from it. The color scheme is soft and monochromatic, featuring pastel shades of purple and pink, which give the illustration a calm and clean aesthetic. The lighting suggests a calm, indoor setting, with shadows gently cast to the right, indicating a light source from the left. The floor is tiled, hinting at a typical bathroom flooring.

Adding a bidet to your bathroom can greatly improve your personal hygiene and reduce your environmental impact. Bidets are growing in popularity in the US as an eco-friendly alternative to toilet paper. Installing a bidet is a relatively easy DIY project that can be completed in just a few hours. This comprehensive guide will walk you through the entire bidet installation process step-by-step.

Be sure to thoroughly read the installation guide specific to your bidet model before getting started. The following sections go into more detail on key steps like working with supply lines, making watertight connections, and testing for leaks and proper operation.

Working with the Toilet Water Supply

When installing bidet fixtures, you’ll need to disconnect the existing toilet water supply line and add fittings to connect your bidet while still supplying water to the toilet tank.

Here are some tips:

  • Locate the shutoff valve for the toilet water supply line. It will either be on the wall behind the toilet or down by the floor on the supply line.
  • Before disconnecting any supply lines, turn off the shutoff valve first.
  • Drain and disconnect the supply line from the valve using a utility knife or pipe cutter, not a hacksaw. This will allow you to easily reconnect the line later.
  • For bidet attachments, install a T-valve adapter fitting to divert the water line to both the toilet and bidet fixture. Hand tighten first then use a wrench for a watertight connection.
  • Wrap all adapter fittings with 2-3 layers of Teflon tape to prevent leaks.
  • Check local plumbing codes for requirements on supply line types and connection methods. Use metal braided lines for durability.

Following manufacturer instructions for your specific bidet model, connect the supply lines from the bidet to the adapted toilet water supply or plumbing shut-off valves.

Making Watertight Connections

Creating watertight seals is crucial when installing bathroom plumbing fixtures. Here are some best practices:

  • Teflon tape: Always wrap threaded fittings with 2-3 layers of Teflon tape. Wind it clockwise as you look at the threads so tightening the connection doesn’t undo the tape seal.
  • Wrenches: Use proper wrenches to tighten fittings. Avoid pliers that can strip fasteners. Don’t over tighten.
  • Sealants: Apply clear silicone sealant on seating surfaces between fixtures and floor/wall. Smooth with wet finger before securing fixture.

Tip: Rub a bit of soap on fittings and gaskets to lubricate before tightening. This allows you to tighten connections properly without damaging parts.

Checking for Leaks

Before using your newly installed bidet, it’s critical to thoroughly check for leaks, especially on any adapted or added water supply line connections.

Here is the proper process to test for leaks:

  1. With the bidet fixture fully secured, turn back on the main water supply.
  2. Examine all connections for immediate leaks. Tighten if necessary but do NOT overtighten.
  3. Fill the toilet tank and allow it to refill a couple of times, flushing in between. Check the water level in the tank for proper fill height after flushes.
  4. Run the bidet self-cleaning cycle according to manufacturer instructions. Check for leaks again during operation.
  5. Let the bidet run for at least 10 minutes, testing all functions. Closely examine ALL water connections for seepage or dripping.
  6. Wipe dry all connection points and wait 5 minutes before rechecking for any delayed, small leaks that may not appear immediately.

Catching leaks now will prevent possible water damage down the line. Small drips can slowly ruin flooring or framing if not addressed early.

If leaks persist at fittings that pass water like supply line adapters, detach, re-apply Teflon tape, and reinstall carefully. Use sealants sparingly as needed. Call a plumber for chronic large leaks.

Testing Proper Bidet Operation

Once installation is complete, verify full and proper functionality using the manufacturer provided instructions. Here is an overview:

For basic bidet attachments:

  • Test cold water stream pressure and aiming adjustment knobs
  • Check that the water inlet filter/screen is clear of debris
  • Confirm the bidet hose doesn’t interfere with lowering the toilet seat

For electric bidet seats/standalone bidets:

  • Install batteries in the remote
  • Check that all electric functions activate: heated seats, warm water flow, fan dryer
  • Slowly adjust water temperature, stream position, spray width to preferences
  • Ensure water heating elements don’t exceed safe temps to prevent scalding
  • Troubleshoot as described in user manual for any error codes

Take note of any quirks, small leaks, or irregular performance right away rather than after months of use where problems originating from installation are harder to pinpoint.

Maintaining Your Bidet

Like any complex bathroom appliance, bidets will require occasional maintenance. Follow these tips to keep your bidet running properly for years:

Daily:

  • Wipe down exterior surfaces with soft cloth
  • Ensure water filters and inlet screens are gunk-free
  • Check for leaks on supply lines

Monthly:

  • De-scale interior water paths and spray nozzles with cleaning vinegar if mineral buildup present
  • Clean jets and deodorizing filters with brush and mild detergent

Yearly:

  • Inspect T-adapter and supply valves for flow issues
  • Check seat mounting hardware is properly torqued
  • Test water temperature regulation and thermal safety

Replacing fuses, adjusting water pressure, and updating firmware can also ensure optimal performance. Consult manufacturer maintenance quick cards or videos for your specific bidet model.

Catching small issues before they become big headaches keeps your bidet working great and extends its lifespan. Proper installation is the first step!

Troubleshooting Common Bidet Installation Issues

If you encounter problems getting your bidet up and running, here are solutions to a few of the most common installation headaches DIYers face:

Water leaks:

  • Check Teflon tape; rewrap and tighten fittings
  • Adjust supply line connections with wrenches
  • Examine fixtures/hoses for cracks requiring replacement

Water spray misaligned:

  • Check angles and positioning of nozzles
  • Readjust aim controls and mounting as needed

Features not activating:

  • Ensure electrical outlet works and provides needed wattage
  • Check fuse, try replacing batteries in remote
  • Examine all control connections to fixture

Toilet running constantly:

  • Verify bidet T-adapter not blocking toilet tank fill valve
  • Adjust toilet tank water level as needed

Carefully compare your setup to installation diagrams for your model to identify issues. Follow troubleshooting advice in owner’s manuals as well. Call manufacturer tech support or a plumber for problems persisting after systematic checks.

Enjoying Your New Bidet

Once properly installed your bidet provides a more refreshing, eco-friendly bathroom experience daily. Here are a few quick tips on getting the most out your bidet:

  • Keep remote nearby but avoid dropping in toilet!
  • Start slow on pressure; high-powered stream can be a surprise
  • Adjust stream position and water heating to your preferences
  • Experiment with pulsating/massaging spray modes
  • Use rear wash cycles for optimal cleaning; women can use front as well
  • Wipe thoroughly after wash cycles then dry off

Bidets take a little getting used to but make your bathroom routine cleaner and more sustainable. Installing one yourself using this DIY guide saves hundreds of dollars.

So relish your new bidet and let the family battles commence over customizing the perfect wash modes!
