Review Image by Ernest Alston 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

    • 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

    • Tankless Water Heater Valves
Exactly what is necessary to hookup at time of install. Great value for $. Easy to install. Quality of valves themselves is super. No leaks 4 years now.

    • Good valve set with pressure relief to the side of the unit
Used to connect to my new Rheem demand water heater. The pressure relief valve points to the left facing the heater, and protrudes and exits past the edge of the heater, requiring cutting the piping cover and insulating the relief for freezing weather. It is not a major problem, and overall these worked well. ... show more

    • For my tankless install
Perfect for my tankless on demand hot water installation.

    • Worth it!
These are very heavy duty valves and worth it. Our plumber was impressed with the quality of these valves. They are a great compliment to our new tankless water heater. With the main valve opened to the fullest, these have excellent water flow and pressure. These allow us to easily access the water to flush our system yearly, as needed. The size and design were perfect! Very functional! ... show more

    • Works amazing
Great quality and value for my money. This is much more expensive at your local hardware store for the same product. The functionality is great; no leaks and easy to install yourself.

    • Don’t use the teflon tape that comes with it
Worked great for my Takagi tankless system. Save yourself the headache and don’t use the teflon tape that comes with it, super thin and nothing but leaks. Used store bought teflon tape and no issues.
