Toilet Water Shut Off Valve Replacement

Replace a leaky toilet water shut off valve. Complete installation instruction on how to replace a straight or angle water shut off valve.
If the water won't shut off to a toilet when you turn the valve, it's likely that the rubber washer inside of the water stop valve is no longer making a good seal. The washer on straight & angle valves are not replaceable, so if the shut off valve is leaking, it will need to be changed out.
If the water shut off valve is leaking at the stem or it won't turn, then the water shut off valve possibly could be repaired.

You do not have to replace the valve. Remove the old flat washer and slip a new one over the mushroom shaped pin that is there. Simple as that. If you need to replace the valve for some other reason, then this is an OK video.

[@Know-How-Now]

Thanks for the lesson, Phil. You got me on that one. I've wondered why no screw to change the washer.... didn't know one could just be popped on there.

[@philnovinger1962]

@@Know-How-Now I had to change the washer on one of my shut off valves yesterday and the valve has the pin, and not a screw. I was reminded of this video and thought I should make a comment, as changing out the entire valve is some trouble when it is sweated onto copper pipe like mine. I do like the clarity of your video and it provides a lot of useful information.

[@Know-How-Now]

I do my best to give good and accurate advice on the videos. I appreciate that you took to the time to write the note. KZbin does not allow me to make changes to the video. If I make a new one, it's possible that it doesn't get to the first search page. Unfortunately, good and concise content is not always rewarded. I will pin this to the top of the comments hopefully people will read it.

[@meinasalon]

For the price of a valve and how easy it is to replace, best to replace the whole valve.

[@HienDang-ks2ht]

i have a very odd situation. I turned my valve clockwise until it stopped, but the water didn't shut off. I then turned it counter clockwise and the water shut off. Now when i turn it clockwise, the water didn't come back on. I even turned it counter clockwise again just to see and the water didn't turn on either. Something is wrong? could it be the valve itself? Initially, i had trouble turning the valve clockwise. It felt stuck , but i had to add a bit of elbow grease to turn it.

[@kellykeefe3610]

I have completed plumbing repairs for years. My manager asked me to make this repair-after contractors had broken the toilet valve. I thought this repair involved a compression fitting for securing the valve. I told my manager; the contactors broke the valve have them fix it! I'm glad it was decided to have a certified plumber make the repair. After watching this video, I would attempt this repair.

PB Blaster penetrating oil is my go to when I am going to work on something that looks like it will not easily come loose. I treat the connection on the day before I want to do the work.

Great job. The only thing I would suggest is to not use an adjustable wrench. But if that’s all you have it does the job. Good video.

[@Itsme-vo4fx]

A trick for those with soldered valves is to purchase a new valve (exactly like the one you have) and then just remove the inner stem assembly from the old one and do the same with the new valve. Then simply switch the old with the new stem assembly. No need to unsolder the valve and solder a new one in place. Just replace the inner guts.

[@Know-How-Now]

Thanks for taking the time to contribute to the video. I love helpful comments. There is another option if the valve is really old, and in a difficult to replace location. Most of mine are over 70 and the manufacturer is no longer in business. I've swapped the stems from one that is easily accessible to the hard to replace location, then soldered a new valve into that location. Also, if the valve doesn't have a screw holding the washer in place and it's a button, you may be able to slip a new washer over the button and fix the valve.

[@SmittenKitten13]

This was super helpful. I feel almost optimistic that I might be able to fix this myself.

[@Know-How-Now]

Best wishes for the repair, Natasha. If a connection is stuck, get a can of PB Blaster penetrating oil (sold a the big box hardware stores). Spray it on the stuck connection, gently tap the connection a few times, then wait an hour. If it still won't come loose treat again, wait and try again. I usually treat any old connection 24 hrs before doing the work. PB Blaster has a terrible odor, ventilate the area. Thanks for subscribing. Welcome to Know How Now channel.

[@emsmkivgolf]

This is awesome! I have a tank that hisses and trickles out of the top of the fill valve. Replaced that and it’s still happening occasionally. The water valve doesn’t turn off the water, so I figure this has to be the cause. Gonna tackle this project soon and this is exactly what I needed. Thank you!

[@Know-How-Now]

If you have a PRV (Pressure Reducing Valve - AKA water pressure regulator), it may have failed and your water pressure is too high. I have a video that shows how to check your pressure: kzbin.info/www/bejne/r4TJknWsi5uYbpY There are also videos on the channel about PRV's . Click on the channel name, Know How Now, find the playlist tab. The videos are organized by topic via playlist. You might consider subscribing to the channel, it's free and you will always be able to find the KHN videos. They don't always come to the top of the search page.

[@emsmkivgolf]

Know How Now that other video is a huge help. I think you are right because I found out that after I flush and the fill valve hisses and trickles, if I turn on the cold water for a split second (has to be the cold water), it immediately fixes the toilet and it refills no problem. So I’m thinking you are spot on about the pressure being too high and turning on the cold water is lowering the pressure enough to allow the valve to activate properly.

[@Know-How-Now]

Great to hear the other video was helpful. If you didn't notice, there is also a video showing how to replace a PRV. If you have decent basic plumbing skills you can replace the PRV.

Both the water pump pliers and the adjustable wrench are directional when you use them (this is so there is less chance of slippage (In the video they are shown used in the wrong direction)other than that great well explained video

[@Know-How-Now]

Thanks for pointing the directional use of the pliers and wrench. It's been over two years since I made the video, I think there were times where I could only use the wrench/pliers the wrong way. There are tight quarters in the area where I was working. Not only did I have to fit my arms & pliers and wrench in the space, but needed to get camera in there too while keeping my arms out of the way. For clarification the correct use of the pliers & adjustable wrench is to position them so that you turn the pliers/wrench towards the lower jaw.
