Hi, this is Nicholas Iarocci, The Home Source Guy, president and owner of Source Development Inc., a residential and commercial construction company in Garnerville, New York. And this is: how to repair a toilet stand pipe. A stand pipe or an overflow tube maintains the water levels before the flush valve opens and lets the water flow from the top tank into the bottom bowl. So what happens once in a while is that these over time, in the older tanks they were made out of brass, now they're made out of plastic but over time the deteriorate, the crack. You might notice a leakage in the toilet, you might notice it runs once in a while. So this is something to look at. Now they do have repair options. They have tapes that rap. They have certain epoxy's that you can use to repair them. But I really suggest replacing them. Once they break I really would replace them. So like I said, you want to match the standpipe that's required for your toilet. So lets replace it. We're going to turn off our supply valve. We're going to loosen up our supply tubes, evacuate the tank, remove any residual water that's left in the tank. And then loosen the bolts at the bottom. Sometimes the bolts get tight, get old and they're corroded. You might have to cut them off. So while you're replacing the overflow on the toilet you may as well replace the the spud gasket. Since the overflow goes through the tank and into the spud gasket. I wouldn't repair, excuse me, the overflow unless you're looking for a very temporary fix, it's really not going to help you out. Again, once a certain portion starts to corrode, most probably it's just going to reflect the status of the rest of the valve. So you don't really want to keep it that way. You just want to replace it. So once you've removed all the bolts you're going to remove the top tank from the bottom bowl. So we're just going to get some protection for our toilet. We're going to lay that on the toilet. Okay so we're going to take the top tank off and set it on our bowl. We're going to disconnect the overflow, it's attached to the spud gasket. And again this is new. Some of the older ones that are made out of brass really give you a hard time. Now the overflow was connected to the flush lever as well. That's been disconnected. Pull off the overflow, and this is our overflow for this particular model. And what happens is, if this is cracked or if it's deformed or if you don't have a good seal water is going to trickle ever so slightly and you're going to get a bowl that keeps running over and over again. So, like I said, if it is cracked, any fix is probably temporary, it's really not going to last, so replace it. So in our model we're reinstalling the same one because it's a new toilet. But if you had an older toilet you'd find the same model again. We're going to apply some plumbers grease at the bottom of our flange here, to give it a water tight seal. So once that's been applied we're just going to reposition the overflow back through the spud gasket. Stick the nut, tighten that up. So once that's all done the overflow's in place, we're ready to install our top tank to our bottom base. The one last thing we need to do is take some plumbers grease and just apply a little bit on the spud gasket. The spud seals the top tank to the bottom bowl. Lets position the bolt holes, drop it in place, take our nuts and bolts, and tighten them up one at a time. I'm pushing down on the stem of the spud gasket to make sure expands. So once their replaced and snug, we're going to tighten them with an adjustable pliers. I actually like using a socket wrench, just for clearance issues. Reconnect the supply, I'm going to reconnect our overflow and we're going to turn on the water and check for leaks. Now if there is any leakage, one point I want to make is you don't want to over tighten the bolts, that are on the spud washer between the top and the bottom bowl. You don't want to cause the china to crack. So once we've checked for leaks, we're done. And this was: how to repair a dripping toilet standpipe.
