Shower leaking flood test to check for leaks

Shower leaking flood test to check for leaks withing the shower. Start at the bottom and work your way up the walls.

1. Shower leaking? Is it the shower floor?
Clean the shower floor and let dry completely. Use a good-quality duct tape to cover the drain. I like to cover the drain and at least 6 inches on all sides.

Now, using a different water source such as a garden hose or another bathroom, fill buckets with water. Use this water to fill the shower until the water reaches the level of the threshold.

What will this test tell you? You are taking the water from another source to determine that the leak is not from the plumbing in this shower.

After the shower floor is filled with water, you must let it sit. This is the time-consuming and boring part, but it’s also the part where you save money instead of hiring someone to do the waiting for you.

Depending on which floor this shower is located, you might see water or water marks on a ceiling, or when you look in the basement or crawl space. The idea is to use the process of elimination and keep looking for any evidence of a leak each step of the way.

If you see a leak at this point, there likely is a problem with the shower base. This is probably a job for a professional. see our shower leaking images and services on how fb page where current shower repair prices cost.

After letting the water sit for at least 15 minutes, if you see no evidence of a leak, the problem is probably not in the shower floor.

2. Shower leaking? Is it the drain?
Next, peel the tape off the drain and let the water flow out. Check for leaks again. If you see one at this point, it’s fairly certain the problem is with the drain.

If you are comfortable doing plumbing work, typically a drain can be repaired easily, especially if the pipe is PVC.

3. Shower leaking? Is it a leak in the grout in the tiled shower walls?
If the shower drains and there is no leak, then you will need to examine whether the leak is coming from missing grout between tiles on the shower walls.

To do this, focus on one wall at a time. Starting low on the wall, splash or spray water on an isolated area, and keep checking for leaks as you work your way up, a couple of feet at a time.

Do a visual inspection of the grout before and after you dampen each area. You are looking for missing grout; even a small hole in the grout can cause a leak.

Once you’ve soaked one wall, go to the next one, all the while checking for leaks.

Once you think you’ve found the source of your leak, repeat the test in that area to be certain you’ve isolated the leak.
