    • Clean-Looking, Heavy-Duty Valve Kit for Tankless Setup!
Review Image by Emily A
This was a husband purchase for our tankless setup, and it turned out great! It arrived safely, and the heavy-duty brass material immediately stood out—it feels super solid, durable, and built to handle long-term water pressure without issue. The installation process was super easy and went smoothly from start to finish. In terms of compatibility, the standard 3/4-inch IPS connections hooked right up to our unit without needing extra adapters or guesswork. Its functionality is top-notch, offering smooth valve action and reliable performance for isolation and flushing maintenance. The color-coded handles make for fantastic ease of use, making it completely clear which line you are operating at any given moment. Plus, the overall appearance is very neat, polished, and looks nice and clean in our space. ... show more

It is great. They are heavy and seems of good if not excellent quality. You still need to buy the 1/2 to 3/4 from the heater to the valves, but other than that, they make the service and maintenance too easy. Again, buy the correct matching since these are too big for the water heater, but other than that, it is kind of plug and play. ... show more

Review Image by Ernest Alston
I recently installed the Hydro Master Tankless Water Heater Valve Kit, and I’m thoroughly impressed with its performance. This kit made the installation of my tankless water heater incredibly easy and hassle-free. The valves are of excellent quality, providing a secure and leak-free connection to the system. It includes everything you need for a complete setup, and the instructions were clear and straightforward, making the installation process smooth. Since installing it, I've noticed improved water flow and temperature control, and I love that it’s designed to protect the water heater from potential damage during maintenance or repairs. The durable construction gives me peace of mind, knowing that it will last for many years. Overall, the Hydro Master Tankless Water Heater Valve Kit is a must-have for anyone installing a tankless water heater. It simplifies the setup, enhances system performance, and adds an extra layer of protection. Highly recommend! ... show more

    • Good, cheaper than most, but cheap sealant used.
After install I found that both leaked slightly just below the balls sit, where the male adaptors screw into the main body holding the ball portion in the valve. I had to disassemble each and reseal the threads with fast setting sealant. When opened I found they used inferior sealant that was all cracked in the threads. Once I did that, both were leak free. Other than this issue, these are worth the price. Much cheaper (know why!) than Watts or others. ... show more

    • High quality fixtures at a phenomenal price.
I bought an electric tankless Stiebel Eltron Tempra 36pro water heater and used this heavy duty, solid brass, 3-valves set of hot, cold, and pressure release valves that came with the correct gaskets, so I didn't have to buy them separately. The valves fit perfectly straight out of the box. These solid brass valves for tankless water heaters are also a phenomenal price and they arrived overnight with FREE Prime shipping! And, the biggest bonus of all was this plumbing valve kit listing price is just 8% of the valve kit price I received from all five plumbing quotes. I highly recommend this product and this seller for stellar service and in my opinion I give this seller and product a10 out of 10. Thank you for a great buying experience.👏🙌😃 ... show more
