How to Safely Flood Test Your Wet Room

Creating a wet room is an exciting project that can add value and luxury to your home. However, ensuring its waterproofing is effective is crucial before you start tiling. 

At Wetroomstop, we understand the importance of a properly sealed wet room, which is why we're sharing our expert guide on how to safely flood test your wet room.

Why is Flood Testing Important?

Flood testing is a critical step in the wet room installation process. It helps identify any potential leaks or weak points in your waterproofing system before you proceed with tiling. This can save you significant time, money, and hassle in the long run by preventing water damage to your property.

What Do You Need for a Flood Test?

Before you begin, gather the following items:

• A suitable drain bung or air bag

• A measuring tape or ruler

• A marker pen

• A water source (preferably a hose)

• A timer or clock

When Should You Perform a Flood Test?

The ideal time to conduct a flood test is immediately after applying your waterproof membrane. If you're using a high-quality product, you can begin testing straight away. This allows for a fast-track flood testing procedure on-site.

How to Prepare Your Wet Room for Flood Testing?

1. Ensure the entire shower area has been properly tanked with a waterproof membrane.

2. Apply the membrane to the entire shower area plus a minimum of one metre in all directions for optimal protection.

3. Allow the membrane to cure according to the manufacturer's instructions if required.

What's the Step-by-Step Process for Flood Testing?

1. Seal the Drain

Use a suitable drain bung or air bag to plug the drain outlet. This is crucial to prevent water from escaping during the test.

2. Mark the Water Level

Using your measuring tape and marker pen, mark a line 12mm above the floor level around the perimeter of the shower area. This will serve as your reference point.

3. Fill the Area

Slowly fill the shower area with water until it reaches the 12mm mark you've drawn. Be careful not to overfill.

4. Start the Timer

Once you've reached the desired water level, start your timer.

5. Observe

Monitor the water level closely for a minimum of two hours. Look for any signs of water level decrease or leaks outside the wet room area.

How Do You Know if the Flood Test is Successful?

A successful flood test meets two criteria:

1. The water level remains the same throughout the two-hour period.

2. The waterproof membrane remains intact with no signs of damage or leakage.

If both these conditions are met, congratulations! Your wet room has passed the flood test.

What Should You Do After the Flood Test?

Once you've completed a successful flood test, carefully remove the drain bung or air bag and allow the water to drain completely. Then, inspect the area thoroughly for any signs of moisture or damage. If everything looks good, you can proceed with tiling your wet room.

What if the Flood Test Fails?

If you notice a decrease in water level or any leaks during the test:

1. Drain the water immediately.

2. Allow the area to dry completely.

3. Inspect the waterproof membrane for any visible damage or weak points.

4. Repair or reapply the membrane as necessary.

5. Repeat the flood test after repairs to ensure the issue has been resolved.

Are There Any Safety Precautions to Consider?

While flood testing is generally safe, keep these points in mind:

• Ensure proper ventilation in the area to prevent mould growth.

• Be cautious of slippery surfaces during and after the test.

• Keep electrical devices and outlets well away from the test area.

• If you're unsure about any aspect of the process, consult a professional.
