Did you know Bathroom water supply lines should be replaced every 10 years?
The reason is because they can leak and create tons of water damage.
So today’s tutorial will show how to replace water supply lines, specifically for toilets and sink faucets.
We’ll discuss common leak points and show what water connectors make this super easy.
Let’s dive in!
Replace Bathroom Water Supply Lines Without Leaks
One of the biggest problems when swapping out water supply lines is knowing how tight the connections should be.
Obviously this is important to prevent water leaks.
Most directions say to hand tighten then use a wrench for the last 1/4 to 1/2 turn.
But my hand tighten is different from your hand tighten…and certainly the same goes for the Rock (who probably doesn’t need a wrench!).
Fluidmaster has great water connectors with Click Seal technology. Btw, we’re partnering with Fluidmaster because they make fantastic products that we’ve been using for years.
We recommend Click Seal connectors because they work like gas caps and click when they’re tight enough. Very cool.
Here’s the deal, no tools are needed with the faucet Click Seal connectors but you do need a wrench for the toilet version – just for the shutoff valve side.
Plus, if you’re not sure what size nut connects the existing supply line to the shutoff valve get the Universal Kit. It has adapters for three common sizes of shut off valve.

Always helpful with great videos. Thanks!
Thanks Steven, good to hear from you and hopefully the tips help!
Thanks Jeff. I am about one hundreds and have typically weak female hands. This is good to know. I’ve inherited my Dad’s old home and it looks as though everything needs to be replaced or improved. I appreciate so very much the information you provide to us. Thank you.
Enjoy your vids. I don’t think I heard you say–the toilet tank should be emptied first, right?
I’ve tried to use replacement water lines in the kitchen and bathroom similar to the type you mentioned (although not the click type). Problem is that the flexible braided stainless steel hoses use a type of plastic hose in their interior that allows bacterial growth in some kinds of well water and gives the water a *terrible* odor. When I’ve instead replaced the hoses with a PEX-type hose, the problem completely goes away and stays away (for years!). The issue I described is what can happen with some well water systems. Even though the flexible hoses you mention are very convenient and easier to install, they may not work for all situations.
Thanks, Informative video, thank you. Now I’m armed to replace the water lines. What about the washing machine water lines. I have the braided lines but a friend has made me nervous about the install.
Your video is so helpful and contains lots of information. Replace your water supply line with Fanovo’s products. Use quality products and enjoy hassle-free experience.
Is it possible or are there ways to hide the water supply lines for a wall mounted sink? I’m fine with the P-trap showing, but we are hoping to have the water supply lines hidden.
I just replaced my bathroom water lines and faucet. Everything is 3/8. The base of the water lines will not connect both ends are females and no 3/8 nipple doesn’t fit. The washer inside is blocking it from threading. I tried pushing down and turning and still won’t connect. What next? I have pics.
