How To Repair a Leaky Sink | How To Replace a Sink Shut Off Valve

we have a leak in this sink we're having a hard time figuring out where it was coming from because it wasn't anywhere down these pipes and yes there is a P trap under the house so don't come at us for the plumbing here we tracked the source down to being this valve right here so we're going to be removing this valve today and replacing it this one has CPVC pipe coming in the back side so we're going to be cutting that off with a hacksaw and replacing this whole valve so the first thing you need to do is cut off the water to your home and make sure that you turn on the faucet so that all the water drains out we just have a short hacksaw here we're going to use to cut the pipe and we're going to cut it as close to the fitting as we can I'm also going to release the nut on this valve you can do this with a pair of Chanel loocks or some pliers uh Channel like just make things a little bit easier CU it you can get a better grip on things if you have a pair of PVC Cutters like these you can get a nice clean Edge on this where you don't have as much clean up to do so I just took some sandpaper and cleaned up that outside we want to make sure there's nothing on there that would prohibit a good seal then we're going to take a paper towel and make sure everything is really dry now we want to test fit our fitting just going to slide it on there make sure everything's good you want to make sure when you're working with this you're using CPVC glue not PVC glue you're going to make sure you get a good coat on here all the way around but thin then you're going to slide your fitting on you only have 5 minutes of work time so make sure you get it on there quickly and we're going to let that sit for 5 minutes to glue itself down and then we're going to screw the valve into it okay so now we have our valve I wrapped Teflon tape around the threads it's not 100% needed but it definitely is always a good idea when working with plumbing now we're just going to thread this on when you're wrapping your Teflon tape always do it the same direction of the way you're threading on so it doesn't just pull it off I'm just going to give it a little half turn here and the last thing to to do is to connect the supply line and I also put Teflon tape on that joint you're going to wait at least 1 hour for the glue joint to cure and then you can turn on your water if you're working with hot water which would be on the other side here then you would wait 6 hours for it to cure but in 1 hour we'll turn this on you'll have one person inside at the joint while the other person goes outside and turns the water on so you can yell at them to turn it off quick if you have any leaks but definitely test for leaks I always check the day of for leaks and I check the the day after as well just to make sure everything is good to go thank you so much for making it to the end of the video it'd be awesome if You' click that logo in the bottom left hand corner to subscribe to my channel and maybe even check out one of my other videos shown on the right as always I hope you guys have a great day
