Replace Old Bathroom Water Supply Lines (Without Leaks!) -- by Home Repair Tutor

Here are the supplies we used

--------------------------------------------------
Bathroom water supply lines should be replaced every 10 years. Do this sooner if there's corrosion or rust on the supply line.

The first step for toilets or faucets is to turn the water off at the shutoff valve.

Then remove the supply line from the shutoff using a crescent wrench, turn the nut counterclockwise.

Typically water toilet water supply lines are hand tight at the fill valve. But pliers can be used to loosen them. Faucet water supply lines need both a crescent wrench and basin wrench for removal.

ClickSeal water connectors don't need any tools for installation at the toilet and faucet connection.

Thank you so much brother I just accepted an offer on my house and literally came home to find my toilet leaking from the top of the water supply line and the realtor wasted no time scheduling the inspection without asking me in 2 days your video is a lifesaver god bless

Excellent. This is the most helpful video I've seen to help me understand exactly how to attach water supply lines to toilets.

I just want to say thank you for introducing me to these hand installable lines. I thought they were gimicky at first, but after looking at them at home depot, the design seemed sound so I bought a couple to try. After spending 10 minutes on my back struggling under a sink with 2 oversized wrenches trying to remove the old nut installed plastic lines, and then taking about 2 minutes out from under the sink to install these new ones by hand, I'd agree these are by far superior for install and removal. That is, assuming they are durable and long lasting, that remains to be seen, but so far I really like these.

Great video! Never knew you didnt need to drain the tank.

[chairboi]

Don't forget to empty the tank before doing this.

Just an FYI, the "Basin Buddy" or the Home Depot version "Faucet Nut Wrench" blows the doors off the standard basin wrench for this task. The nuts mounting the faucet are nearly always very hard to reach and likely both frozen (even plastic) and worn out some. The "BB" is a closed design and locks on, the standard basin wrench is open-ended. Pro tip, tap on the BB wrench with a small hammer to let it seat well before you crank them off, thanks for your work

Thanks for the video. I intend to refer back to this once I get the hose. I did a real doozie. Toilet was leaking from fill valve connector but my mom who I was doing the repair for thought it was her toilet seal into the floor leaking as the screws were rusted out. Sure I lifted up the toilet and replaced the seal and screws but cracked the hose resting the pressure of the 75 LB toilet against it. Now I'll be making this repair too! Hey at least by the end of it she will have all but a new toilet!

This video helped me today to fix leaky supply line

[WilliamTaylorII]

Helped me install my new bidet attachment. Just needed to know which direction to turn the connector. Thanks!

[melrow]

Is it necessary to empty the water out of the tank 1st?

[tonnjabraden]

This was excellent, and fixing it myself saved me at least $200 bucks! I really liked the that you explained the fitting sizes and recommended taking the old piece with me to the hardware store. After buying the correct items, its was super easy to replace. Thank you again.

[Scrimpets]

Well, just as helpful as can be! Thank you!

[BUBBLESMOMMOM]

Thank you for such a great video! The way you explain everything is so helpful; this is the best video I have watched and understood. My only problem is that I am having a difficult time trying to remove the connector from the main water supply. I am trying to turn it to the left; on the video it looks like you are turning it to the right. Righty tidy, Lefty loosely. What am I doing wrong because I cannot get it to turn. Thank you again!!

[gustavovega]

Great information. I am going to replace both of my toilets. A friend just had a busted water supply while sleeping for the night and made huge water damages to the house.

Shout out to the the Clark Kent of home improvement for this helpful vid!

I like your videos. I've seen others you have done and you make it so simple. One thing I haven't seen discussed however is when connecting a water valve to a copper water line, how tight should you make the connection. Mine was leaking and I didn't know if it was because when removing my vanity, I had turned the nut too tight in the wrong direction before I realized that it turns clockwise when removing and counterclockwise when tightening. I replaced the connection with a new valve, nut and Ferrell and didn't know exactly how far to tighten the connection when putting it back together. Another idiot thing I did without thinking is that once I installed it, I didn't check to see if the valve was open or closed and when I went outside to turn the water back on, I came back into the house and heard a sound like Niagara Falls! I immediately knew what it was and ran back outside to turn the water off. That was one big mistake on my part. The damage it caused was unbelievable! It had stripped the popcorn from my ceiling and water was everywhere! LOL Just wanted to mention to check the valve to see if it is in the on or off position before turning the water back on. LOL

Thank you for posting this! Has anyone had where the piece inside the tank spins when you’re trying to loosen the piece attached to the actual toilet?

[freddiemac]

Great vid and easily explained. My issue now is, the water supply line I had on my previous toilet is 20", I've upgraded to a newer toilet and it's taller. The 20" supply line doesn't cut it and i need something longer. I haven't been able to find anything longer than 20" is there any way to extend a water supply line from the water feed?
