Overflow Screens: What They Are and Why Your Tank Really Needs One
Let’s be honest—most of us don’t spend a lot of time thinking about water tanks or what’s hanging off the end of an overflow pipe. But if you’re using a water tank at home, on a farm, or in a commercial setup, there’s one little detail you really shouldn’t overlook: the overflow screen.
It’s a small thing, but it can save you a lot of hassle. So, what exactly is an overflow screen, and why should you care about it? Let’s break it down.
First Off… What Is an Overflow Screen?
An overflow screen is a simple device that fits onto the outlet of a tank’s overflow pipe. Its job is to let water out when the tank gets full—but more importantly, it keeps all the other stuff out. Think insects, small animals, leaves, and other debris that have no business getting into your water supply or pipework.
In other words, it’s like a filter for your tank’s overflow system. It lets water escape but blocks anything that could cause problems down the line.
So Why Do You Need One?
At first glance, a screen might not seem like a big deal. But trust us, once you know what it’s protecting you from, you’ll see it’s well worth having.
1. It Keeps Your Water Clean
Overflow pipes are basically open doors. Without a screen, bugs and even small rodents can crawl in, bringing dirt and bacteria with them. If you're using that water for drinking, irrigation, or even just washing, this can lead to serious contamination.
An overflow screen acts as a barrier, helping keep the inside of your tank clean and safe.
2. It Stops Blockages Before They Start
Ever dealt with a blocked pipe? It’s not fun. Leaves, twigs, and other bits of debris can easily find their way into an open overflow outlet and cause clogs. That can lead to overflowing tanks, water backup, and even damage to your system.
A good screen keeps all that gunk out, saving you time, money, and frustration.
3. It Keeps Critters Out
Mice, frogs, insects—you’d be surprised what tries to crawl into a tank through an overflow pipe. Not only is that gross, but once inside, they can do real damage to your system and water quality. A screen blocks their path and keeps your system pest-free.
4. It Helps You Stay Compliant
If you’re running a business, farm, or commercial property, you probably need to follow certain health and safety standards. Overflow screens are often required by regulations to prevent contamination and protect water systems.
5. It’s a Cheap Fix That Prevents Expensive Problems
Let’s be real—overflow screens aren’t expensive. But not having one? That can cost you a lot more in cleaning, repairs, or system downtime. Installing a screen is a small job with big benefits.
The Different Types of Overflow Screens
There’s no one-size-fits-all, which is why companies like MP Products offer a bunch of different styles. Here's a quick look at the most common types:
- Female thread screens: These screw directly onto male-threaded pipes. Simple and secure.
- Male thread screens: For the opposite setup—female-threaded pipes.
- Compression connector screens: Perfect when you don’t have a threaded fitting. These use a clamp or press-fit design.
- Flanged screens: Built for larger, heavy-duty setups with flanged pipe connections.
- Universal connector screens: If you’re not sure what kind of fitting you have, these are adjustable and work with different pipe types and sizes.
Where Do You Use These Things?
Basically, anywhere there’s a water tank with an overflow pipe. That could be:
- A rainwater harvesting system in your garden
- A livestock or irrigation tank on a farm
- A greywater or drinking water storage system at home
- Industrial tanks or commercial plumbing systems
If it holds water and has an overflow outlet, it can probably use a screen.
Are They Easy to Install?
Absolutely. Most overflow screens are designed for quick, tool-free installation. You just screw them on, press them into place, or tighten a compression fitting. It’s a simple job that anyone with basic DIY skills can handle in a few minutes.
Final Thoughts: Small Part, Big Protection
Overflow screens might not be flashy, but they’re one of those small additions that can make a big difference. They keep your system clean, prevent pests and debris from getting in, and help you avoid blockages and repairs.
So whether you're managing a rainwater tank at home or maintaining a larger commercial system, adding an overflow screen is a smart move.
