Reddit mentions of KES SOLID Brass T-adapter with Shut-off Valve, 3-way Tee Connector for Handheld Bidet 15/16" and G 1/2 Polished Chrome, K1018-CH

"it" is the adapter that connects the toilet water supply to the bidet. The cheaper units come with a pastic one that works fine for a while but may eventually fail. Here's an example of a metal one

Get a separate, metal T valve to put between the bidet hose and the toilet intake (instead of the crappy plastic T that most of those bidet's come with). I have one there and have the pressure turned down almost all the way.

This is the one I got.

It definitely does, yes. I did quite a bit of research before buying and was willing to spend around $100 or so but this specific model had the best overall reviews and added features for females as well, your gf will thank you I'm sure. (Side note, I initially ordered the blue but it looked, idk cheap somehow so I exchanged it for the white only and it looks much, much better, not cheap looking at all.)

A couple suggestions on other things that make a big difference imo for another $20 combined roughly, both recommended by other reviewers as well as a few specific YouTube installation videos (there is one that finally sold me on it, I'll see if I can find that too). A better/more solid and lasting brass, chrome finish T-adapter which also has a shut off and is compatible with this model (the 185 comes with a plastic one and only a few reported leaks and it doesn't have a shut off either and will eventually need to be replaced down the line). As well as toilet seat bumpers, taking into account the bidet only raises the seat a little but enough to not make it feel solid, the bumpers make it feel as it should, 100% solid with them.

The links for you to check out and maybe add to your wishlist (I personally highly suggest them):

Edit: This is the YouTube link where the guy uses the upgraded adapter as well as the bumpers and shows how to install easily too. (You'll see the 185 features that do make a big difference to me.)

Mostly need plastic to be moulded to my design, and other parts assembled.

*Braided steel hoses, high pressure faucet valves, these guys

I installed my cheap-o bidet using a T-valve, so I can shut off the water line when it's not in use. Like this: https://www.amazon.com/gp/product/B00JIG4AGM

I recently installed this - life changing! Not warm water, but you get used to it. Installed with a screwdriver for the mounting bracket, and adjustable wrench for the fittings

Never had a problem with leaks with the Luxe. If you're afraid of leaking it may make sense to upgrade to a brass T-adapter

Replace the plastic connector with a metal one like this. Not only will it not drip, it will give you the ability to regulate the amount of water that is directed to the bidet.
