1. Angle Shut Off Valve With Escutcheon Plate And Supply Line
I am extremely satisfied with these valves. I recently had to replace the valves in all three of the toilets in my house due to a suspected leak, and these valves worked like a charm. I found a helpful video on YouTube that guided me through the process, and it was much easier than I anticipated.
One important thing to remember when changing these valves is to shut off the water supply and verify that it is indeed off by turning on a faucet nearest to the valve. It's also essential to have the new valve ready to go because there will still be some water in the line, even with the water shut off. I recommend having a big towel on the floor and two crescent wrenches – one to stop the valve from turning and the other to loosen the nut holding the valve.
Breaking the nut free may require a bit of torque, but once it's loose, it should turn by hand. The new valves are incredibly easy to install, and the connection to the toilet is straightforward. The first valve took me around 15 minutes to change because I was a bit nervous, but by the time I reached the third one, I was able to do it in just 7 minutes. It's also helpful to have someone by the valve after you replace it.
Before turning on the valve, leave it off and slowly turn on the water main. If there are any leaks, it indicates a problem that needs to be addressed. Luckily, I didn't experience any leaks. Once you've confirmed that there are no leaks, you can turn on the water main at full pressure and monitor for any drops. Make sure the valve line to the toilet is securely connected before conducting the leak check.
The nut that holds the valve needs to be tightened quite firmly, so using counter-torque with an opposing wrench is crucial to prevent the valve from twisting while tightening the nut. Overall, the installation process was incredibly easy, and I am extremely satisfied with these valves.
Additionally, I was pleased to find that these valves are of good, heavy quality. They come with all the necessary conversion bits, making them suitable for all sinks. The valve itself looks nice and is not made of plastic, which adds to its durability and aesthetic appeal.
I made a mistake by not ordering the valve with Female iron pipe threads, but I can't fault the product for my own oversight. The included braided hose also looks good, and the wall cover would fit perfectly if I didn't have iron pipe.
2. Ez-Fluid Angle Stop Valve – Shut Off Ball Valve
I recently purchased this multi-valve for my refrigerator and kitchen faucet water lines, and I must say that I am impressed with its performance. The installation process was a breeze, although I did notice that it does not have flats on it for a wrench. However, this did not pose any major issues for me.
One of the standout features of this valve is its individual shut-off valves for each water line. This allows me to easily control the water flow to my refrigerator and kitchen faucet separately. The shut-off valves work well, and I have not experienced any leaks so far. This is a major improvement compared to using a single valve with two outlets.
I initially purchased a different brand from a big box retailer, but I was disappointed to find that it leaked massively from the 1/4" shut-off handle. Thankfully, this valve has proven to be reliable and leak-free. Not only that, but it also comes at a lower cost and allows for different-sized faucet and ice-maker connections in one device. The packaging from the manufacturer was also neat and well-presented.
In terms of functionality, this valve has exceeded my expectations. It works perfectly, allowing me to connect both my refrigerator and water faucet effortlessly. The ability to close off the water flow individually is a great convenience. I have not encountered any issues with the valve, and I highly recommend it to others in need of a similar product.
The delivery of this valve was also commendable. It arrived promptly and the service was fantastic. With this valve, I was able to connect my faucet and ice maker using just one water source. Although the product claims to be drinking water safe, I cannot vouch for it as I have hard water. However, I will certainly check on it when I install a reverse osmosis system later this year.
3. Chrome Quarter Turn Water Shut Off Valve – Kitchen/bathroom
I recently purchased three of these shut off valves and I must say, they have been a great addition to my home. I had some old valves that I was hesitant to use, so I installed these in line to easily turn off the water supply to my toilets when I am away. It's a convenient and cost-effective solution.
One of my toilet water supply valves was not sealing properly, causing a constant trickle of water whenever I worked on the toilet. I decided to install this shut off valve after the leaking valve and it solved the problem completely. It's a much cheaper alternative to hiring a plumber to install a new valve.
When I was replacing my dishwasher, I wanted to add a shut off valve to the supply line connected to the kitchen sink hot water line. I couldn't find one at local hardware stores, but luckily, I found this valve on Amazon. It is well-made and the quarter turn function is smooth and leak-free. Now, if there is a water leak with the dishwasher, I don't have to cut off the water supply to the sink.
In another instance, I had installed a new floor and the shut off valve for the toilet was too close to the floor to easily turn the handle. I used this shut off valve between the valve and the hose, and it worked perfectly. It solved the problem and allowed me to easily control the water flow.
Like many other reviewers, I needed to shut off the hot water supply to my kitchen for dishwasher maintenance, but I didn't want to turn off the sink hot water faucet. Additionally, my existing valve was not fully stopping the water when turned off, leading to messy leaks. I installed this shut off valve between the existing valve and the dishwasher hose, and it worked like a charm. It was easy to install with some teflon tape on the male threads and now I am considering ordering the "5 pack" to be prepared for any future valve issues in my house.
4. Chrome Plated Brass Valve Set 1/2 X 3/8 (5 Pack)
I recently purchased these quarter turn angle stop shut-off valves for a remodel job, and I must say that I am extremely impressed with their performance. Unlike the previous valves I had purchased from a plumbing contractor supply house, these valves have proven to be reliable and durable.
One of the key features that stood out to me is the proper alignment of the ferrule in the valve. This ensures a leak-free installation. The instructions provided were clear and easy to follow. By assembling the ferrule in the valve without the pipe, ensuring the back of the ferrule is square with the nut, and then sliding the assembled valve over the pipe to the stop, I was able to prevent any potential failures caused by a slightly cocked ferrule.
I initially bought a case of 24 valves, thinking I would have a couple of extras in case of defects. However, three years later, I have replaced all the professional plumbing supply house valves but have not needed to use the spare valves. This speaks volumes about the quality and reliability of these valves.
Although they are made in China, I can confidently say that these are the best quarter turn valves I have ever used. The fact that they are lead-free is confirmed by the LF etched on the squared body of the valve. The lead warning on the package is simply a requirement in California, and it does not affect the safety or quality of the valve.
In terms of functionality, I love the quarter turn ball valves compared to the traditional crank valves. They provide a quick and easy shut-off with no leaks. I was disappointed to find that my local big box hardware stores no longer carried quarter turn ball valves with a compression fit. However, ordering from Amazon was a convenient and efficient solution.
While some may blame Amazon for putting local businesses out of business, I believe that it is the responsibility of these businesses to adapt to customer demands. Amazon simply provides a platform for customers to find and purchase the products they need. In this case, I needed the quarter turn valves immediately to complete a repair job, and Amazon delivered them within two days.
5. Water Shut Off Valve With Disconnect Clip: Pack Of 2
Superior to Home Depot: More Affordable and Improved Handle Design
I have had previous experience with Home Depot's Sharkbite fittings, and I must say that these ones are much better. Not only are they cheaper, but the handle design is also superior. Unlike the snubby handles from Home Depot, these fittings have traditional handles that are easier to grip and turn. The shiny surface of the handles also ensures that your hand won't slip off while in use. Additionally, the handles are designed to fit your hand comfortably, allowing for better control compared to the Home Depot fittings, which only accommodate one finger and your thumb.
One of the main advantages of these push-on pressure fittings is that they provide an excellent solution for homes that heavily rely on plastic and glue in their plumbing systems. When these plastic valves give out, it can be a hassle for individuals who lack plumbing experience or don't want to spend a fortune on hiring a plumber. Moreover, some people may feel unsure about which glue to use or may simply be uncomfortable working with it. With these push-on fittings, all you need is a clean cut, and the fitting easily slides down and locks into place. I have been using one on my hot water system for three years now, and it still hasn't developed any leaks. Just last week, I replaced my cold water system with these fittings, and I'm highly satisfied with the results. The installation process only requires a hacksaw, and it's crucial to shut off the water supply beforehand to avoid any mishaps.
In my case, I needed straight stop valves under my kitchen sink, and these fittings were perfect. They easily pushed onto the pipes after I cut away the old soldered valves that were leaking. The difference in functionality and convenience was remarkable.
I purchased these fittings to improve the connections under my sink and replace a few failing gaskets in my daisy-chained multi-turn shut-off valves. Initially, I was hesitant about buying off-brand Sharkbite fittings, but the reasonable price convinced me to give them a try. I ensured that I made clean and straight cuts on my supply lines, cleaned the copper with steel wool, and the fittings installed flawlessly without any issues or leaks. My only suggestion for improvement would be for the manufacturer to provide the insertion depth information, similar to what Sharkbite does. However, as long as you press these fittings firmly, ensuring the pipe goes in all the way, you will have no problems.
6. Eastman 1/2" Fip X 3/8" Od Angle Stop Valve
The quality of this shutoff valve is impressive. Unlike many other valves available at big box stores, this one does not have plastic components. It was easy to install by soldering a male adapter onto the water line and using thread tape to secure the valve. The installation process was straightforward and it also allows for easy future maintenance. Although I cannot speak to its long-term durability, my first impressions are positive.
I decided to order these valves online for my bathroom renovation project to ensure timely delivery and avoid potential stock issues at the store. The valves are of good quality and function as expected. It's a convenient option to have them delivered to my doorstep.
I am pleased with this valve's performance. It works as it should, and with the added benefit of prime delivery, I didn't even have to visit the store. It's hard to find any faults with this product.
I was specifically looking for a simple shut-off valve that I could easily attach with plumbing tape. This valve fulfilled my requirements without any complications such as compression fittings or soldering. It's a straightforward and hassle-free solution, especially if you have a male thread on the end of your pipe.
This valve has been holding steady without any leaks. It's the preferred method for adding an ice maker water line, particularly if you don't have copper pipes.
7. Yoo.mee Shut-Off Brass Ball Valve 1/2'' Standard Connections With Polished Chrome Finish
I recently purchased the shower shut-off valve and I am extremely satisfied with its performance. Unlike other types of shut-off valves that claim to maintain water flow but disappointingly reduce it, this valve lives up to its promise of not obstructing water flow. The open ball valve design allows for unobstructed water flow, and if you want to adjust the pressure, simply turn the handle until you achieve the desired pressure.
I was initially skeptical about the manufacturer's claim that the valve wouldn't hold back water indefinitely, but to my surprise, I left it on for seven days with full water pressure and experienced no drips or leaks. This product exceeded my expectations.
Installation was a breeze. As someone who worked in a water department for 36 years, I can confidently say that this valve is of high quality. It feels sturdy and well-made, with the only plastic parts being the handle and the ball shut-off inside. When the valve is open, it provides a complete hole for water to flow through. I believe even my teenage daughter could install this valve with ease.
Many people may purchase this valve to fix leaky showers, but my use case was to conserve water while in the shower. I wanted an easy way to turn the water off or reduce the flow when lathering or shaving. After researching different options, I chose this valve because of its ball valve design, which prevents any potential restrictions. So far, it has been working great. It completely shuts off the water, doesn't cause any noticeable restriction when fully open, and allows for easy flow adjustment.
The handle turns smoothly and effortlessly, and my only minor complaint is that it cannot be mounted in the opposite direction. However, this is a negligible issue. The valve appears to be made of solid metal and feels durable. I am particularly impressed with the ease of turning the handle, which was a concern of mine.
In terms of additional parts, I also purchased a WaterPoint extension arm and a HammerHead all-metal shower head to complement this valve. These products are of excellent quality as well. I used Mill-Rose Blue Monster PTFE tape for the connections, and it worked perfectly.
8. Brass Water Shut Off Valves – 2 Pack
I recently had the unfortunate experience of having a handle on the valve under my sink break off, leaving me in need of a replacement. After conducting extensive research and reading numerous reviews, I finally settled on a set of valves that exceeded my expectations.
The installation process was a breeze, and I encountered no leaks whatsoever. These valves performed flawlessly, providing me with the functionality I needed. Considering the price I paid, I was pleasantly surprised by the value I received.
I primarily purchased these valves for a couple of plumbing projects, including the installation of a new dishwasher. I appreciate the ability to isolate individual appliances, and these valves allowed me to do just that. The ease of installation and quick on/off functionality make these valves a practical choice. Should the need arise, I would not hesitate to purchase them again.
One aspect of these valves that impressed me was the inclusion of thread sealant tape for the pipe connection. This thoughtful addition ensured a successful outcome during installation. It's little touches like this that elevate the overall quality of the product.
As someone who is revamping old plumbing systems, I can attest to the effectiveness of these valves. The installation process was straightforward, and they performed flawlessly. These valves have certainly made my plumbing revamp project much more manageable.
9. Triple Handle 3-Way Water Ball Valve
The hot water line connection for the sink and dishwasher works perfectly with this high-quality shut-off valve. The installation process was easy, and the valves operate smoothly without any leaks. It's worth noting that there are no flats for a wrench, but I managed to install them using a rag to protect the chrome from my pliers. Having separate valves for the sink and dishwasher is convenient, as it allows me to shut off the dishwasher without affecting the hot water supply to the sink.
One of the standout features of this shut-off valve is its hard-to-find configuration. The build quality is excellent, and the handles appear to be made of metal rather than plastic like most other brands. I also appreciate that it came with a wrench surface, although it could be wider. However, it should still work well unless you require excessive torque.
While the valve generally works well, I did encounter some issues during installation. When using blue Teflon pipe dope, there was some leaking due to the threads not being properly tapered. I had to remove and reinstall the valve using pipe dope, Teflon tape, and more pipe dope. Although the valve still bottomed out, it is now leak-free. Additionally, the lack of places to use a crescent wrench was a minor inconvenience, as I had to resort to using a pipe wrench on the threaded part, resulting in some damage.
10. Chrome Brass 1/4 Turn Angle Stop Valve
I recently installed this double shutoff valve in my new kitchen, specifically on the hot water line. I must say, it has made a significant difference in terms of convenience and functionality. Now, I can easily shut off the dishwasher separately from the sink faucet, which is quite handy.
The installation process was a breeze, and the valve has been working flawlessly ever since. The quarter turn mechanism is incredibly smooth, suggesting that it is a high-quality shutoff valve. I am confident that it will continue to perform well in the long run.
One of the standout features of this valve is its versatility. It effectively connects the hot water to the dishwasher while allowing hot water to flow through the faucet. This functionality is particularly useful when I need hot water at the faucet and want to run the dishwasher simultaneously. I highly recommend this product for anyone looking to achieve this level of control and convenience in their kitchen.
Furthermore, I was pleasantly surprised to discover that these double valves can be used to control water flow to multiple devices. By adding a tee on one or both valves, you can control three or even four devices effortlessly. This flexibility is fantastic, especially for those who require more complex water management systems.
Personally, I utilized this valve to add a separate bar faucet to my kitchen sink for filtered water. I installed a 3M Filtrete filter under the sink, and the shutoff valve played a crucial role in separating the filtered water from the regular faucet. I couldn't be happier with the results.
The overall design of this valve is worth mentioning as well. I particularly appreciate the arrangement where one hose connects to the water faucet while the other connects to the dishwasher. This design not only looks clean and organized, but it also ensures that there are no leaks. I have had this valve installed for two months now, and I haven't encountered any issues or leaks during this time.

Additionally, if you experience low water pressure or no water flow at all when the valve is turned on, it suggests a malfunction.
Lastly, a valve that does not completely shut off the water supply, even when fully closed, indicates a faulty valve that needs replacement. If you encounter any of these signs, it is recommended to consult a professional plumber for inspection and necessary repairs or replacements.
