Does Your Pool Waterfall Leak?

Estimated reading time: 4 minutes

You’re here because your pool has a leak and you want to rule out the waterfall.

Pools in Texas are a tricky thing! The soil shifts, the weather constantly changes from freezing to 100 degrees, and your pool pipes don’t stand a chance.

But when your pool leaks, how can you tell where the leak is coming from?

In many cases, it is pretty tricky, and you need a pool leak detection specialist. But for many waterfalls and water features, even pool leak detection companies need to run diagnostics that may take a day or two.

Why is this?

Pool waterfalls and water features are often built in a way that makes it impossible to pressure test.

For a company like ours, here at True Blue Leak Detection, if you follow these steps and find out that the source of your leak is your waterfall, we will entirely skip the price of the leak detection and jump straight to repairing your pool.

Who doesn’t want to save an extra few hundred bucks?

So, without further ado, here are the steps to determining if you have a leak or not in your water features.

Step One – Determine that your pool has a leak.

Before you check to see if you have a pool waterfall leak, make sure your pool is losing water from a leak first. This winter, we saw evaporation levels as high as 1/4″ per day.

That’s insane! But it’s true. So it may seem like you have a pool leak because you are filling up your pool more, but you may not.

And you know what we really hate… charging people for a pool leak detection just to tell them they don’t have a leak. It makes us sad.

So, if you haven’t done a bucket test, do that first:

If your swimming pool is losing half an inch or more a day, you won’t have to do a bucket test. But it is good to get an idea of how much water your pool is losing.

Step Two – Look Around the Back of Your Waterfall

If you see water coming out of the grout or between the rocks in your waterfall, you have a pool waterfall leak. The good thing about this is that you won’t need a pool leak detection expert to come out to tell you you have a leak in your waterfall because you’ve just found it yourself.

At this point, call a stonemason and have them re-grout your waterfall. That should do the trick.

And to be sure, after you’ve had that repair done, then do the bucket test again to make sure. Oftentimes, pools may have multiple leaks.

Step Three – Do a Bucket Test With The Pool Water Fall Off and Then With It On

This is important. And also a little tricky.

It’s important because it compares the water loss from when the water features are running and when they are off.

It’s tricky because the pool will lose water faster with evaporation when the waterfalls are running.

So, if the pool loses a tiny bit of water when the waterfalls are on, it’s probably not your a pool waterfall leak.

However, if you’re finding that either a) the pool only loses water when the features are on or b) your pool loses even more water when they are running than off, it is safe to assume you have a water feature break.

*** Important Note

If your pool waterfall or features are on a separate pump, there is one extra step you have to take.

Most water features run on the same pump that runs the entire pool system. So you most likely won’t have to follow this step.

If your water features are on a separate pump, you need to take off the lid to the pump that goes to your water features after you turn off the system and the valves to the features.

Once you have done that, then do a 24-hour bucket test and measure your water loss.

That it!

If you do these tests, tell your leak detection expert what you’ve found, and you will be able to save time and money, and you will feel like your own leak detection expert. After all, nobody knows your pool better than you do!
