Plumber Blackburn

You may have heard of a backflow prevention device, but you’re not sure what it means or how it works. You want to install one at home, but you don’t know where to start. We’re here to help! This blog post will walk through everything you need to know about installing a backflow prevention system at home as per Plumber Blackburn —from why they’re important and how they work, all the way down to tips on when and where best to use them.

Why do you need a backflow prevention system at home?

It’s important to understand the risks of drinking contaminated water. If you have any type of plumbing or drainage system, there is a chance that it could lead to contamination. This can happen if debris or other materials enter your plumbing and get into the water supply line. The contaminants will then make their way into your home, causing illness and sickness in those who drink it. Plumber Blackburn advises homeowners to install a backflow prevention device as acts as an extra layer of protection against these types of problems by reducing or eliminating any risk associated with entering another part of your home’s plumbing system through an opening such as a toilet flapper valve, Blocked Drains Blackburn or showerhead spigot (which may be located near where people wash their hands).

What are the types of backflow prevention devices?

The most common types of backflow prevention devices are check valves, pressure vacuum breakers, and double check valves.

  • A check valve (also called a “check” or “check valve assembly”) is like a one-way gate that allows water to flow through it in one direction but not the other.
  • A pressure vacuum breaker (also called PVB) prevents pressure from building up in pipes when there’s no water being forced through them by an operating pump or siphonage system; it does this by releasing any excess air from inside its housing before closing off the valve at high-pressure levels so that no more air can be sucked into its opening.

How do you prevent backflow?

  • Check your system regularly. Every few years, inspect the entire plumbing system and replace any parts that become worn out or damaged, such as copper pipes, valves, and regulators. If you have an older home with lead-based solder (which was used until recently), make sure to replace these fixtures as well.
  • Not tampering with your backflow prevention system. Do not open or tamper with any part of it unless specifically instructed by a qualified professional who knows how to work safely around water systems like yours!
  • Avoid letting water sit in pipes for extended periods of time – this can create pockets where bacteria could grow unnoticed until suddenly causing serious problems such as Legionnaires’ disease if left unchecked long enough before being detected at all since most people won’t get sick until after having been exposed repeatedly over time without realizing what’s happening underneath their noses all along.”

When to call the expert?

If you are not sure what to do, or if you want to save money and time by doing it yourself, then call the expert. If your water heater is installed by an experienced plumber and is under warranty, he or she may be able to fix it without having a backflow prevention system installed there. The same goes for any other plumbing fixture that uses hot water—if there was no way for the water heater’s output line (or its supply pipe) to get into your home’s main line before being piped through another location, then installing a backflow prevention device would be unnecessary since all of these locations are protected against small amounts of contamination.


It’s vital to know the different types of backflow prevention devices and how they work. If you have questions about what your system needs, call a professional Plumber Blackburn!
