So, whether you’re a homeowner or a professional builder, keep reading to learn everything there is to know about drain testing!

What is a Drain Test?

A drain test is a simple test you can do to determine if your building’s drainage system is functioning properly. This test is typically used in buildings that are not yet occupied, such as construction sites or warehouses.

To perform a drain test, first check to see if the water main feeding your building is operational. If it isn’t, call a plumber to make repairs. Next, locate the building’s flood control valve and turn it off using the handle. Once the valve is off, place a bucket underneath the valve and wait 10 minutes. If there is no water flowing from the bucket when you remove it, then the drainage system in your building is likely dysfunctional and needs to be fixed.

How to Do the Drain Test

Building drain tests are an important part of ensuring the functionality of a building’s plumbing system, as well as its compliance with current and future codes. The following steps can be used to perform a drain test:

1. Inspect all Building Services pipes for obstructions.
2. Verify proper water shutoff valves are in place.
3. Test all accessible drains by sucking out a small amount of water and checking for blockages.
4. Check all manholes and roof vents for obstructions or leaks.

What to Expect During the Drain Test

There are a few things you should expect during your drain test for building control. The first thing is to make sure all the proper safety precautions are taken. You should also make sure that the drain is properly cleaned before starting the test. After cleaning, you will need to place the drain in question under water and wait until it clears. Once it clears, you can start measuring how much water flows through the drain per minute and record this information.

Results of the Drain Test

The drain test is a simple way to determine if your building controls are working properly. To perform the test, use a garden hose to fill a bucket with water and place it next to the drain in your building. If the water starts draining into the bucket quickly, then your building controls are likely working properly. If the water drains slowly or not at all, then you may need to make adjustments to your building controls.


If your home or business has recently had flooding issues, there is a good chance that water damage was caused by building leaks.Leaks can occur in any part of the building – from the roof to the basement – and can cause extensive water damage. To determine if you have a leak and whether it needs to be fixed, you will need to do a drainage test.
