Why I Believe a Backflow Preventer is Necessary for Outside Faucets

As a homeowner, I have come to understand the importance of having a backflow preventer installed on my outside faucets. At first, I didn’t see the need for it and thought it was just an extra expense. However, after experiencing a backflow incident, I quickly realized the necessity of this device.

A backflow preventer is designed to keep contaminated water from flowing backward into your drinking water supply. This can occur when there is a sudden drop in pressure in the main water line, causing water to flow in the opposite direction. Without a backflow preventer, this contaminated water can enter your home’s plumbing system and potentially contaminate your drinking water.

Not only does this pose health risks to you and your family, but it can also damage your plumbing system and appliances. Contaminated water can cause corrosion and buildup in pipes, leading to costly repairs or replacements. It can also damage appliances such as dishwashers and washing machines, reducing their lifespan.

Installing a backflow preventer on my outside faucets has given me peace of mind knowing that my family’s health and our home’s plumbing system are protected. It is a small investment that

My Buying Guide on ‘Backflow Preventer For Outside Faucet’

As a homeowner, I understand the importance of ensuring the safety and functionality of my outdoor faucets. One essential tool for this purpose is a backflow preventer. In this buying guide, I will share my knowledge and experience in purchasing a backflow preventer for outside faucets.

What is a backflow preventer and why do I need one?

A backflow preventer is a plumbing device that prevents the reverse flow of water from entering your home’s water supply. This can occur when there is a sudden drop in water pressure, causing contaminated water (such as from a garden hose or sprinkler system) to flow back into your clean water supply. This can lead to health hazards and damage to your plumbing system.

Types of backflow preventers

There are various types of backflow preventers available in the market, but for outside faucets, the most common ones are atmospheric vacuum breakers (AVB) and pressure vacuum breakers (PVB).

– AVBs are the simplest and most affordable type of backflow preventers. They are usually attached directly to the faucet or hose bib and use air pressure to keep out any contaminants.
– PVBs are more complex and have multiple components. They are typically installed above ground on a riser pipe near the faucet or hose bib. PVBs use both air pressure and check valves to prevent backflow.

Considerations before buying

Before purchasing a backflow preventer for your outside faucet, there are some factors you should consider:

– Local regulations: Some areas have specific regulations on which type of backflow preventer is required for outdoor faucets. Make sure to check with your local authorities before making a purchase.
– Water pressure: Different types of backflow preventers have different pressure requirements. If you have low water pressure, an AVB may be more suitable as it requires less pressure to function properly.
– Ease of installation: If you plan on installing the backflow preventer yourself, make sure it comes with clear instructions and is easy to install. PVBs may require professional installation due to their complexity.
– Durability: Look for high-quality materials such as brass or stainless steel that can withstand harsh outdoor conditions.

Budget

Backflow preventers can range from $10-$100 depending on the type, brand, and features. While it may be tempting to opt for a cheaper option, investing in a quality backflow preventer can save you money in the long run by preventing costly repairs due to contaminated water.

Maintenance

Regular maintenance is essential for keeping your backflow preventer functioning properly. AVBs should be inspected annually, while PVBs may require more frequent inspections depending on local regulations.

Final thoughts

Investing in a high-quality backflow preventer for your outside faucet can provide peace of mind knowing that your clean water supply is protected from harmful contaminants. Consider local regulations, water pressure, ease of installation, durability, budget, and maintenance when choosing the right type of backflow preventer for your needs. With this guide in hand, you can make an informed decision and ensure the safety of your home’s water supply.
