Four Things to Check if your Tub/Shower is Leaking Below

Four Things to Check if your Tub/Shower is Leaking Below

Second or third floor bathrooms are great, but if there is a leak in the shower, it’s hard to know where to start!  There are many possible places that a tub or shower can leak water.  If you have a leaking shower, then don’t proceed with your repairs until you know these ways to diagnose common problems. Step #1 Test to see if the problem occurs when just the shower runs or does it also appear when water runs from the tub spout (if you just have a shower without a tub, then you will need to modify these procedures slightly). Water running from tub spout Run lots of water out of the tub spout and monitor the wet area. You may have to let it dry up before you can really see if new water is appearing.  If the leak is on a drywall ceiling below, then consider cutting a small inspection hole to help evaluate your test results.  If you still find water below, then proceed to step #2.  If you see no water from this test, then that means that the leak is either in the riser pipe that runs from the valve to the shower head inside the wall OR from water that is splashing inside the shower and finding a way through the surfaces in the shower. The Bucket Test To further narrow down these two options to one, examine the water flow carefully while the shower is running. Does it clearly spray out of the shower head or is there water streaming back to the wall? If water is running against one of the walls, then correct the problem. If you don’t think this is the case then have a helper hold a large bucket under the shower-head while testing again. View inside wall Run the shower this way for 2 or 3 minutes (or for longer if it normally takes longer for the leak to show up) dumping the bucket in the toilet or sink, as needed. Most likely this will prove to keep the leak from showing up because leaks in the pipe behind the wall are very uncommon. If your leak has been kept away by this, then the problem is not inside the wall. You most likely have a problem with a seal in the surfaces of your shower. Caulking and sealing are in order. If, after the bucket test, you’re still getting leaking water below, then you most likely have a problem with the plumbing inside the wall. Find a place to get access and cut a work hole to make the repair.  If either of these two results has revealed the problem. No need to go to step two. Just get to work! Step #2 Next let’s do another test. Stop the drain and fill your bathtub with water. Make sure that the drain is holding water and not seeping through. Fill tub with water You can usually hear the water seeping if you turn off the water and listen carefully. Let the water stand in the tub for several hours and see if the leak is present. If so, then the problem is on the top side of the tub where the drain assembly is supposed to seal to the tub. The solution is to unscrew the drain assembly and reseal it with plumbers putty (or clear silicone if you have a cultured marble tub). You have found your problem! If your test results in no water, until you un-stop the drain that is, then you can proceed to step #3! Step #3 Now let’s look further down. We have isolated the problem to below the tub surface. Cross section of tub drain In the image above you will see the bath drain shoe. On the bottom of the tub is a thick rubber seal that is pulled tightly up against the bottom of the tub by the drain shoe to keep water that goes down the drain from leaving the constraints of the pipe. This is your next most likely spot to have a problem. This seal can dry up and crack over time and lose its ability to seal. This can be replaced from the top by removing the drain assembly and slipping a new one through the drain hole and resting it under the tub.  Reinstall the drain assembly with plumber’s putty or clear silicone. In cases where the bottom of the tub is visible, simply look at the connections on all the pipes while water is running through them and determine where the leak is. It’s not so easy when the ceiling below hides all this from your view. In many cases the best way to diagnose and repair it at this point is to cut out a work hole below and patch it after the repair is complete. Step #4 If you pass all these tests and still have a leak when the water is running, then you probably have a damaged place in a pipe. Carefully cut into the ceiling or wall to expose the problem area At this point you can start cutting into the ceiling or walls to find the leak knowing that you did everything you could to eliminate the simpler solutions.  Always be careful when cutting into a wall.  Proceed slowly with a hand saw to avoid damaging a pipe or wire. It can cause serious injury, if proper care is not taken. So let’s review: Step #1 Test to see if the problem occurs when just the shower runs. Step #2 Next let’s do another test. Stop the drain and fill your bathtub with water. Step #3 Now let’s look further down.  The bottom seal can dry up and crack over time and lose its ability to seal under the tub. Step #4 If you pass all these tests and still have a leak when the water is running, then you probably have a damaged place in a pipe. I hope that this helps you when diagnosing a drain leak in your tub or shower.

What are Sump Pumps

Sump pumps are electric water pumps that take collected water below the surface of a basement floor and send it out of the house, usually into the yard.

Most sump pumps are submersible, which means that they sit in a sump basin under water and automatically turn on when the water level reaches a certain height.  After running for a few seconds or minutes, the pump should turn off again.   Sometimes this auto switching process breaks!  You don’t really want to find out that your pump didn’t turn on when it was needed most!

Many of you have sump pumps in your basement. We’re going to show you today, in more detail in video format, how to test yours, so that you can be confident it will turn on when you need it to! 

Understanding the Parts of the Sump Pump

There’s a few things I want to mention before we actually look down in the sump pit, or basin. You probably have a lid. A lot of them kind of turn to unlock. So just get your lid off so you can see into the basin. Some of them screw down, and that’s okay.  Just figure out how yours attaches and get that lid off of there.

Let’s look at some of the components of a sump pump. We’re going to look down in the basin later, as I mentioned, but the things you can see on top are a power cord and usually that just plugs into the wall, and a discharge pipe.  Some go under the floor and then up the wall and out. Yours may not do that. Some of them come up and they’re on top of the floor, which is fine, but there’s going to be a discharge pipe somewhere.  

You may have a black flex hose. If you do, that’s okay, but this is going to be a little less reliable, so just remember that. You want to check this for cracks, and replace this with solid PVC piping, at some point.  If you do that, a good rule is to use 1 1/2″ piping size for most residential sump pumps. 

In the video, I show a sump pump. It’s an old one. It’s obviously not the one that we’re going to work on here, but I use it to show you a couple things.

First is that if you have the black flex hose discharge, you’re probably going to have a connector that screws into the pump and then the hose goes on there with a hose clamp. If you have this type, then make sure that clamp is tight.  A loose clamp can cause the flex hose to pop off and then no water will ever get pump out at all! 

Second, is the switching method. We’ll cover the two most common options in this post.  Some sump pumps use a floater with a switch inside of it that moves when you turn it up and down.  If you listen carefully, you should be able to hear it click when you turn the switch upside down.  So when the water fills up in your sump basin, the floater will start to float and it will kick it in the up direction and turn the sump pump on.   

The other common switching method is a floater that is attached to an arm that connects to the switch on top of the pump.  We’ll talk more about that type later.

Keeping the Sump Basin Clean

Another thing to be aware of is that sometimes your sump pump will get kind of cruddy and gross. Sometimes I find even bugs living down in there. A good solution for that is to use a liquid pool shocking chlorine. I usually just pour like a half a cup in there, or less, and then stir it a little.  Now if your sump basin is dry, I probably wouldn’t pour it into a dry sump basin. Put some water in first, maybe a quarter of the way up, and then pour the pool shock into the water and stir it around a little bit. That will kill all the bugs and bacteria living down in there.  That’s a good way to start.

Is the Discharge Obstructed Outside?

Let’s look outside now and find the pipe where our sump pump discharges. Take a look at where your pipe ends up. Is it buried in the grass? Is it being restricted in some way? Just make sure you’re getting good flow out of the discharge pipe on the outside of your house.  I’ve seen many that are completely buried under ground.  This will greatly reduce the effectiveness of your pump!

Basic Anatomy of a Sump Pump

Now we’re back down in the sump basin. We’re going to kind of look at the anatomy of the whole system. The large black bucket is called the sump basin. The most common type, as shown in the video above, has the tubes or the pipes that run around the perimeter of the basement drilled right through the side of the sump basin. When rain water collects underneath the floor or underneath the footing of the house, it migrates through the gravel bed that’s under the floor and into these pipes that have holes in them. Then the water runs through the pipes and dumps into the sump basin. 

There’s another way that you might see this done as well. That’s with small holes drilled in the side of the sump basin all around making it perforated. Then gravel surrounds that sump basin. So when water collects in that gravel, it runs through those perforated areas in the side of the sump basin and just starts filling up that way. Either way, the basis is a low point in your basement where the water is going to collect. So the water collects in the basin and the sump pump sits down in the bottom. Out of the sump pump is a discharge pipe.

Most of the time you will see a check valve in the discharge pipe. A check valve is for one way flow of water. So when water flows up and the pump kicks off, all the water that’s developed upstream, in the head of the pipe, doesn’t run all the way back down and fill the sump basin back up. This kind of holds the water at that point. When more water fills up from the bottom, the pump will kick on and it will pump more water out through the check valve. 

You might also see a slip coupling, which is just for taking your sump pump out and servicing it if you need to. You can loosen the clamps and remove the whole thing to repair or replace the sump pump.  Now we’re getting to the other common type of on/off switch.  That is switch arm with a little float on it. So when the water comes up, it floats up and it raises the arm and trips this switch. You can turn the sump pump on manually by rising the arm.  That should kick the pump on and run the majority of the water out.

Test the Sump Pump

Now, this is what I want you all to do. I want you to try to trip your sump pump and get it started manually. Make sure that it’s running. We don’t want to find out when it’s raining or some early morning you come down to find two inches of water in your basement. You want to find out now if it’s working or not.  If it runs, that tells us that the mechanics are working correctly, but what about the float.  I’ve seen them become saturated and less buoyant.  

I want you to check it another way by pouring water in there.  Take a 5 gallon bucket of water and dump it in and see if the pump kicks on. If you pour the water in and the pump kicks on, your golden! Now you know you’re safe. Now you can feel a little more confident that next time it rains your sump pump is going to kick on, and you’re not going to be stuck with water in your basement. So get out there and check your sump pumps!
