  1. What size is the seal the you replaced on the valve?

  2. Could have smoothed it down with a seat grinder.

  3. Great info and very helpful!
    TIP: Dont forget to place rag over drain!

  4. I like this productσσσ>allmy.tips/DeltasValve?yy    it was easy to install and when you turn the water on it turns very easy with no pressure.

  5. Valve seat wiggles all over the place! Dnt think its tightning . What can it be??

  6. It looks like you repaired the hole in the wall….

  7. THANK YOU your video is excellent, I learned a lot plus I won't be calling my plumber anymore, he kept changing the washer but not the valve seat 🙂 Faucet seat wrench $ 6 at Ace and I got the washer kit for $5… No more drip drop

  8. good video J.G…i just have one question…… i have 2 new valve stems to put in and i noticed that one valve stem comes with a white gasket and the other comes with a black gasket… is the valve stem with the green gasket for the cold water or hot water? thanks in advance for the feedback buddy!

  9. Oh man. I just paid $120 for a plumber to come fix a leaky faucet. 10 minutes and 2 gaskets changed… and 5 days later the leak is back and worse than ever. Found this video, removed the seat, and sure enough there is a good sized nick in the ring. Wish I had tackled it myself in the first placed and saved myself some money! Thanks for the help.

  10. Just a suggestion for anyone trying this.This is a good simple repair video,however before installing the cover and knob you should have turned on the water and checked for leaks way in the back where (you put the teflon tape)the seat is before closing it up,once covered you would never see a leak inside the wall. Otherwise nice video.

  11. good video but valve seats do not come out that easy all the time. actually never.

  12. I always replace both at the same time. If not, I am back at it replacing the other one. Thank you. Good video.

  13. Last note:  it was my valve handle screw head that had snapped off….so I had to drill…but when I did get it off it was fused with mineral deposits. Price Pfister…not bad for 23 yrs….fixed hot water side, cold water side works fine but I bought the kit for both at ACE…about $40.  Saved over $300 on a plumber! I had individual shut off's in  basement.

  14. Whatever you do ,do not force the valve off…wd40 and heat, and go slow, eventually it will screw off.

  15. Thanks, this gave me enough info to fix my leaky shower myself…a few things for those who have 20 yr old valves though….the knob may be fused to the valve stem…you may need to drill it out..start with a 1/16th bit, move up to 1/4"…it will come of.f..but you will need a new valve as you will have destroyed it.   Also, if you can't unscrew the valve from the pipe….aside fromWD 40…use a heat gun or hair dryer….learned this trick taking shotguns apart…give is 30 secs high heat and it screws right off.

  16. My gasket seat stripped . How do I get it out. ?

  17. Quick and to the point, thanks for the info. 

  18. I live in a older house made back in the 70s, I didn't have to cut the main water line to the house off to replace my shower valve stems, is that something only necessary for newer homes are did I just break a plumbing rule by not cutting the main water line off to the house?

  19. Great Video But I would of Changed Both at the Same time Also you said around $2.00 for parts?? Plus unless your a Plumber Most People don't have the Tool Around your Home So that was over $10.00 So Just to let the people Know it is a Easy Fix if you have the right tools Also 99 out of 100 your not going to be able to use an adjustable tool you will need the Socket that fits the Stem to remove it from the wall area And make sure you Turn the Main water supply on the outside of the Home  

  20. Thank you for the video! I was able to change my valve stem myself and stop that constant dripping. Do you have any videos in how to fix a bathroom plug that won't flip down? 🙂

  21. thanks for the very detailed video.  Got both done in an hour including visit to hardware store!  

  22. I had never known what was behind a shower faucet or how to get it off.  Thanks to your video and another video I was able to fix the leak.  I am going to change the stem on all three knobs (hot/cold/shower-faucet knob).  Like Gomer Pyle said, THANK YA! THANK YA! THANK YA!

  23. Looks like you had an easier time than I did.  On my first try I encountered some problems that you didn't have.  First off, I didn't have the pleasure of removing the faucet stem and taking it to the hardware store.  I live in a condo and needed to get permission from the resident manager to schedule a shut off date.  I only had a two hour window to repair my leaky faucet.  Once the water was shut off, I then had to remove the hot water stem with my locking pliers.  While I was able to remove it with the pliers, the surface area to remove the stem was very small. Once I had removed the stem, I had difficulty removing the seat.  I don't know if it was stuck or I wasn't using the seat removal tool correctly.  I probably should have tapped on it a little. Anyway, I replaced the stem with a new one and just utilized the original seat.  Luckily the seat wasn't too damaged and the leaking stopped. Thanks for the informative video though. 

  24. Just watched your video.  I had changed out the washer and a few weeks later my hot water started leaking in the shower again.  This time I changed out the stem valve because I noticed that the metal housing that the washer sits in was deteriorating.  NO MORE DRIPPING!  Thank you!

  25. I had no idea the seats could be replaced. Thanks for the video.

  26. Very informative.  Any advice if the seat is worn and corroded such that the seat wrench just eats away the seat

  27. I replaced the whole stem on my faucet because the brass was chipped. The faucet still leaked, and now I know why. I had no idea that you could replace the valve seat! Thanks for the video.

  28. Thanks for such an informative video, great refresher for me. It's been 10 yrs or more since my last one.  As for your shower head, they sell low pressure "power shower" heads for $5-$6 at Wal-Mart.  Great for a man, the ladies don't care for`m much tho.  Steps up the spray, we had them on Navy ships

  29. What was the purpose of unscrewing the inner sleeve of the valve?

  30. I also had a leaking shower valve and it is fixed now.  I was not sure about the procedure until watching your video.  I have a different stem type but he process is the same and the nut for the stem is not as easily reached.  A five dollar stem wrench from the hardware store solved reaching the nut.  Thanks for the video.  

  31. Thanks for you post. I replaced the faucets on my shower a while back but was still dripping. I saw the vid on how to replace the seats and i did it today. It was just as you show it on the vid. Saved me some bucks and i learned something although i was a little comprehensive at first. Hooray for me, even my bitchy wife gave me a d+ but wtf could i expect from her right ??

  32. Thank you for posting this video. I have the same problem, and although Im pretty mechanically inclined, I was a little skeptical in attempting to repair this myself. But not anymore!! Im especially glad to know I have to turn the water service off. A big dummy associate from H.D. said I didn't have to. So thanks again also, for preventing a possible scalding from hot water. Best to you
