Exact Steps to Install Bio Bidet 6800 (Illustrated Guide)

Today, we’re installing the Bio Bidet USPA 6800, or these days, the 6800U.

If a picture is worth 1,000 words, then a moving picture is worth 10,000. So, every step has a small video to illustrate what you need to to.

Bio Bidet 6800 Installation: Exact Steps

Gather the Needed Tools

You may also need a three-pronged extension cord.

You won’t need much. Grab a towel or a small container for water to fall into. If you use a towel, you can place it on the floor under the spot where the water hose attaches to the toilet tank.

See what kind of screwdriver will be needed to remove your current toilet seat, or just grab what you have and see which is needed when the time comes. You may not need a Phillips, but won’t hurt to have one handy.

I’d grab a rubber jar opener or rag. Anything that will make it easier to grip things and tighten/loosen by hand. That way, you don’t have to worry with an open-faced wrench.

Shut Off the Water and Flush the Toilet

Now, shut the water off at the wall.

There is a small valve that sticks out of the lower wall (or out of the floor in my case) next to the toilet, on the left-hand side.

Locate the valve and give it a turn clockwise.

Next, flush the toilet to empty the tank by holding the lever down until it stops draining. This way, when you remove the hose, you won’t get much water coming out.

Remove the Water Supply Hose from the Toilet Tank

Locate the spot where the hose attaches to the toilet and either place a towel on the floor below that spot, or use a small plastic container to catch the water as it is coming out.

Use a rag or jar lid gripper to grip the hose and turn it CCW.

Attach the T-Valve to the Toilet Tank

Make sure the o-ring is oriented correctly

Locate the T-valve and make sure the little o-ring is situated correctly. The ring might come in the package separately, or may even have fallen out of the T-valve.

In any case, make sure the ring is inside of the T-valve and situated like this:

Thread the T-valve onto the threaded shank that the water supply hose was formerly attached by turning CW with a rag or gripper. Note: it’s CW if you’re looking at it from the underside.

Before fully tightening, make sure the bidet hose port (the one horizontal to the ground) is pointing towards you.

Check to See if You Need the Alternate Water Supply Hose (Non-USA)

If you live in the US, skip this step.

The Bio Bidet USPA 6800 comes with an alternate water supply hose.

In the US, the water supply hose is 3/8″ (shutoff valve) to 7/8″ (toilet tank fill valve).

If you’re outside the US, Bio Bidet has you covered with this bidet. It comes with an alternate water supply hose.

I’m not sure why it comes with the hose but the spare nut is available by request only. If you need the 1/2″ spare nut, then contact BB.

Attach the Water Supply Hose to the Bottom of the T-Valve

The water supply hose should now go into the bottom port of the T-valve.

Tighten firmly with a rag or gripper. You may need to hold the horizontal port in place or re-adjust it a bit after tightening.

Remove the Existing Toilet Seat

Most toilet seats have long plastic screws with plastic fasteners on the underside.

Sometimes, especially with skirted toilets, there will be top-mounting bolts.

If your toilet uses these, you’ll need top mounting hardware from bidet king, since the bidet doesn’t come with compatible screws (at least, not in my case).

If your toilet seat has standard mounting hardware, you’ll probably have a flap-like cover that’s over the bolts. You’ll need to peel that cover back. Sometimes, you’ll need a flathead screwdriver to open that tab.

Use a screwdriver, flat or Phillips, to remove the toilet seat mounting bolts. Grip the underside plastic nut with a rag and start turning the screw CCW.

In the second example (in the video), the bolts are fixed to the toilet seat. This is an uncommon setup–I haven’t had a seat like this before. I simply needed to unscrew the nuts on the underside. There was no need for a screwdriver.

Set the seat aside for now.

Attach and Align the Mounting Bracket at the Back of the Toilet Rim

Locate the plastic mounting bracket.

It should be placed at the back of the rim.

The side with the black grippers should be facing down and the two horizontal gripper strips should be closest to you.

You’ll want to tighten everything down, enough so that you can attach the bidet, but don’t go buckwild.

I tend not to tighten too much at first, until I know whether the mounting plate located correctly–something you won’t know until you mount the bidet. I.e., initially the seat may be positioned too far forward or backward.

Mount the Bidet Seat

Go ahead and mount the bidet, but don’t plug anything in yet.

The wire kept getting in the way when I went to install the seat.

I found it easiest to drape it over the top of the seat until the bidet was positioned just right.

Once the bidet is ready to slide onto the bracket, move the wire off to the side as in the video.

As for routing the wire…

As you can see here, there is a little tab that holds the wire.

The wire that comes out of the bidet is positioned in the middle so that it can be draped to either the left or right side, depending on where the nearest outlet is.

This feature tucks the wire close to the bidet to provide a nice clean look upon installation.

Attach the Bidet Hose

Locate the bidet hose.

Attach the L-end to the bidet and the other to the horizontal port on the T-valve (in any order).

Open the Water Valve

Now, loosen the same valve that you tightened in the beginning. While doing so, check for leaks along the path of the hoses.

Anything that you tightened by hand should be checked for drips.

Plug It in and Test It Out

You’ll probably need an extension cord for this, especially if you live in the US where such bidets are uncommon.

Plug it in and wait 2 minutes. It takes about 2 minutes for the water tank to fill. This bidet doesn’t have an instant heater, so it will take another few minutes for the water to warm up.

After a few minutes, give it a whirl. You can cover the spray jet with your hands. If you’re brave, you can go ahead and try using the bidet.

Conclusion: Bio Bidet 6800U Installation

There you have it.

Hopefully, the installation was straightforward.

The above is an easy scenario. So many toilet designs exist, and problems can arise. If you have a difficult toilet (square rim, fully skirted toilet bowl with hidden water connections, etc.), make sure to check out my other installation guides.

If you’d like to upgrade your bidet at some point, I’ve written some highly-detailed review articles on some of the most popular bidets on the market.

That’s it for now. Thanks for reading.
