Signs Your Fountain Might Be Leaking

Before we plunge into the how-to of testing, let’s ensure you’re looking for leaks in the right place. How do you even know your fountain might be leaking? Here are some telltale signs:

Water Level Fluctuation: Remember when you last filled your fountain? If the water level drops faster than you’d expect (and it’s not just evaporation), it’s hinting at a possible leak.

Excessive Wetness Around the Fountain: A wet patch around the fountain isn’t always a mischievous kid with a glass of water. It might be a sign!

Testing Your Indoor Fountain for Leaks

Now, let’s get down to business. How do you test that cosy indoor fountain?

Visual Inspection: Start with the basics. Look for visible cracks or wet spots. Sometimes, the simplest methods work wonders.

Testing Your Indoor Fountain for Leaks

Dry the Surrounding Area: Before you conduct any tests, ensure the area around the fountain is dry. This will help you spot any new wetness.

Check the Water Level: Mark the current water level with a waterproof marker. Wait for a few hours without using the fountain. Notice any significant drops?

Testing Your Outdoor Fountain for Leaks

Outdoor fountains, while grander, come with their own unique challenges.

Turn Off the Auto-fill System: To accurately test, ensure the auto-fill system is off. This will prevent any artificial maintenance of the water level.

Check the Water Level: Just like indoors, mark and monitor. Nature might be unpredictable, but drastic water level drops aren’t her doing.

Use Leak Detection Dye: Available at most hardware stores, these dyes can be added to the water and will move towards the leak source.
