Common Mistakes To Avoid For Threshold Drain

Have you heard people say something like “This product might look good and get decent reviews, but it broke really quickly for me”? That might be because they have chosen the wrong product for their job.

The threshold drain system is such a good drainage system for residential and commercial properties. Domestic users often install threshold drains in front of doorways to prevent water damage.

Yet, the threshold drain itself can get damaged if we don’t use it properly.

The following 4 mistakes are what people will most likely make that reduce the lifespan of the threshold drain.

Unsuitable Drainage System

Imagine you installed a lovely shallow threshold drain around the driveway where it is most likely to flood after heavy rainfall. Not only the shallow threshold drain won’t help with the flooding situation, but constant water overload will also put a lot of pressure on the threshold and potentially damage it.

On the other way round, if you installed a big threshold drain at a light water volume location like by the pool, it would be total overkill and you would most likely overpay it.

Don’t let this happen to you.

Make sure you identify the water volume to which the threshold drain will be exposed from the beginning.

Wrong Selection of Threshold Drain

After the water flow, the second common mistake people would make is having the incorrect weight load class of the threshold drain for their area.

Weight Load Classes are the standards set by the European Standard BS EN 124:2015 that applies across the UK.

Like all building materials, threshold drains also have a limited number of weights they can handle. If you drive a car over a threshold drain that is only meant for walkways, of course, it might break.

Avoid it!

You should establish what kind of traffic will be moving around the area and check the product specification to choose the suitable threshold drain for the application.

Inaccurate Installation

Now you have the right threshold drain and are ready to be installed, here comes another potential mistake. A correct installation can make or break the threshold drain.

For example, one of the good ways to install the threshold drain is using an anchor to keep it from moving when you seal it in place.  If the threshold drain is moved during the process, it might affect the functionality and cause problems, such as standing water and incorrect redirection of the drainage.

We don’t want that!

Install the drain a few mm below your finished surface to protect it.

Additionally, do more research beforehand and get all the required tools before installation. If you are not 100%, maybe leaving it to the professional is the way to go. Spend a little more for a hassle-free and long-lasting result.

Poor Maintenance

Last but not least, anything will go bad if you don’t care for it, same for threshold drains. So many things can get washed down into the drain, for instance, leaves, stones, trash etc. All of them would affect the drainage performance or even clog the drain completely.

If the situation is left unattended, there is a high risk of the standing water getting under the doorway and damaging the foundation or flooring.

We can do better!

An annual cleanout is a good way to start, it will ensure the water can drain smoothly. A common way to clean a drain is with pressure washing, it can avoid debris and waste from building up. So, schedule it in your calendar.
