Thing to Consider Before Buying Outdoor Faucet Lock

Most people don’t put much thought while buying a lock for an outside faucet. Consequently, they end up buying cheap and poor-quality faucets that start leaking just after a few uses.

To make sure this doesn’t happen to you, here’s a list of all the crucial aspects that you must consider to bag an outdoor faucet lock. Let’s have a look.


As a faucet lock is usually used for outdoor faucets, it must be made from a sturdy and long-lasting material. Steel and Brass are the two materials that are the strongest and most durable. Plus, it’s tough to cut or damage these two materials with regular tools.

It’s also important to check the finishing of the faucet as steel is vulnerable to rust, and brass is prone to corrosion. A good metal coating or paint coating can solve these problems and provide a faucet with an eye-catching look.

However, there’s a few drawbacks of both steel and brass. The materials don’t provide insulation against temperature, and they will cost more than other materials.

If you want something cost-effective, you can opt for plastic or foam-made faucet covers. Plastic and foam also work as insulators and are capable of providing years of service.


If you buy any faucet without checking its measurements, you might find out later that it doesn’t even fit your water faucets! Which means you wasted your money for nothing!

To prevent that, always check the measurements properly before purchasing a lock. First, you need to measure the size of your faucet. Then you can use those measurements to pick up a lock that fits snugly with your faucet.

Generally, most of the locks are made to fit the US-standard 3/4-inch faucets. In case you have a faucet smaller or bigger than that, ask the seller if your desired length is available.

As for the gate valve cover, the most common size is for valves with 2.5-inch to 5-inch diameters. Some brands also offer cover for smaller valves having a diameter of 1-inch or 2-inch. So take your time and look for the size variations until you find the one that perfectly matches your water faucet.


A good-quality faucet should have a strong and user-friendly design. If the lock is designed weak, anyone can open the lock with a mere screwdriver! And you don’t want that. Some brands come up with innovative ideas to make their locks more secure than regular ones.

Try to find one of those amazing anti-theft features that you feel will surely keep the water borrowers away. Also, it’s better to pick a brand that provides an extra lock and key to operate the locking device. This way, you don’t have to spend anything extra.

Ease of Use

With some cheap-quality locks, it becomes impossible to lock and unlock them comfortably. Even sometimes, you might need to cut the whole lock as it just doesn’t want to unlock!

Also, some brands build such complex locks that it takes forever to install them. So check the features and installation system before you buy the lock. The lock should unlock within moments, and it should also be lightweight and easy to handle.

Customer Reviews

When you’re making an online purchase, you have the advantage of checking out the customer ratings and reviews in detail.

As a consumer knows the product best, it’s a good idea to go through the reviews to find out the good qualities as well as the drawbacks of a product. You can also check the Amazon bestseller ratings before making your decision.


Outdoor faucet locks generally don’t cost you much. You can use the price as a filter to get rid of tricky sellers. Surprising low prices stand for bad quality. The more features you expect, the more money you have to pay. Pick up a lock that suits all your needs and your pocket as well.

How to Use Outdoor Faucet Lock?

As there are different types of faucets with distinct features, the usage isn’t the same for all outdoor faucet locks. Here’s how to use the two main types of faucet locks.

Standard Faucet Locks

Most of the faucets usually feature a valve cap with one or several locking holes at the bottom. To use it, you have to take the threaded part of the lock and put it over your faucet. Then you have to spin the other end of the lock until it’s tight.

Once you ensure a tight snug, use the provided key to seal the lock and faucet together. After that, you have to use your lock and key to perfectly secure your faucet. When you want to unlock it, use the key again and follow the mentioned process in reverse.

Faucet Covers

For the faucet covers, you have to use the given rubber loop to attach the cover to the wall behind the faucet. First, put the open end of the cover against the wall. Then create a loop around the faucet with the rubber piece.

After that, simply put the rubber strip to attach the cover with the walls. Usually, the cover has a soft foam pad to ensure a tight fit. Piece of cake, isn’t it?
