Screened Overflow Kits

Everything You Need to Know About Screened Overflow Kits

Here at Precolor Tank Division, we specialise in providing clients with various kinds of water tanks and related products for both personal and commercial use. Today we’re going to focus on a particular aspect of water tanks, which concerns screened overflow tanks.

Why Are Screened Overflow Kits Important?

Screened overflow kits are an important aspect of how storage water tanks work as they make sure that your water tank complies with the legal requirements set by the UK Water Regulations. Based in UK, we make sure to lay the foundations when it comes to British and European standards, having helped to draw up the standards as a company from our fifty years of industry experience. Previously known as Byelaw 30, through the use of screened overflow kits, we can help sure that any existing tanks are meeting the current water regulations.

The Basics

The screened overflow kits that we supply at Precolor Tank Division include the screened overflow fitting, screened warning pipe, and screened tank vent. It is recommended that the overflow is at least twice the size of the inlet into the tank. The design consists of screening mesh, allowing the flow of liquids through the flow passage, but preventing solids from getting through the system.

Available Sizes

When making your decision about which sized screen overflow kit you require, consider the variety of our options. We offer five standard sizes, including ¾"/22mm, 1½"/38mm, 2"/50mm, 2½"/67mm or 3"/75mm. Additionally, we also supply UPVC overflows in either 4 inches, 6 inches, 8 inches, or 12 inches. Whatever size you need, we are sure to be able to find the right product for you.

Rodent Screens

When you require a rodent screen, this offers special protection against both insects and rodents, making sure they are kept out of the water storage tank and any connected pipework, without restricting any overflow. This type of screen system is recommended for refurbishment or renovation works for the protection of pipes during this time.
