Why I Believe Under Sink Thermostatic Mixing Valve is Necessary

As someone who has experienced the inconvenience and potential dangers of scalding hot water from the sink, I strongly believe that under sink thermostatic mixing valves are necessary. These valves work by mixing hot and cold water to achieve a safe and consistent temperature, making them an essential component in any household or commercial setting.

One of the main reasons why under sink thermostatic mixing valves are necessary is for safety purposes. Hot water can cause serious burns, especially for children and the elderly who have thinner and more sensitive skin. By regulating the temperature at the source, these valves prevent accidental scalding incidents that could result in painful injuries or even hospitalization.

Moreover, these valves also help to conserve energy and reduce water waste. Without a thermostatic mixing valve, one may have to constantly adjust the temperature using a separate hot and cold tap, leading to excessive use of both hot and cold water. With a thermostatic mixing valve, there is no need for manual adjustments as it maintains a consistent temperature, resulting in less wasted water and energy.

Another benefit of having an under sink thermostatic mixing valve is its versatility. It can be installed in various types of sinks such

My Buying Guide on ‘Under Sink Thermostatic Mixing Valve’

I recently purchased an under sink thermostatic mixing valve for my bathroom and it has been a game changer. If you are considering buying one yourself, here is a comprehensive guide to help you make the right decision.

What is an Under Sink Thermostatic Mixing Valve?

An under sink thermostatic mixing valve is a device that helps regulate the temperature of water coming out of your sink faucet. It is usually installed under the sink and has hot and cold water inputs, as well as a mixed output that delivers water at a desired temperature.

Why Do I Need One?

A thermostatic mixing valve is especially useful if you have young children or elderly family members at home. It ensures that the water temperature does not get too hot, reducing the risk of scalding. It also helps save energy by regulating the amount of hot water being used.

Factors to Consider

  • Type of Valve: There are two main types of thermostatic mixing valves – pressure-balancing and thermostatic. Pressure-balancing valves maintain a constant ratio between hot and cold water, while thermostatic valves have a temperature-sensitive element that adjusts the ratio based on the desired temperature.
  • Flow Rate: The flow rate refers to how much water can pass through the valve in a given amount of time. Make sure to choose a valve with a flow rate suitable for your needs.
  • Temperature Range: Different valves have different ranges for adjusting the temperature. Make sure to choose one with a range that suits your needs.
  • Durability: Look for valves made from high-quality materials such as brass or stainless steel, as they are more durable and long-lasting.

Installation

If you are not familiar with plumbing, it is best to hire a professional plumber to install your thermostatic mixing valve. Make sure to follow all safety precautions and shut off the main water supply before installation.

Maintenance

To ensure optimal functioning of your valve, it is important to perform regular maintenance. This includes checking for leaks, cleaning any debris or sediment buildup, and replacing worn out parts if necessary.

Budget

The cost of an under sink thermostatic mixing valve can range from $50-$200 depending on factors like brand, type, and features. It is important to set a budget beforehand and choose one that fits within your price range without compromising on quality.

In Conclusion

An under sink thermostatic mixing valve can greatly improve your daily routine by providing safe and comfortable water temperatures. By considering factors like type, flow rate, durability, and budget, you can find the perfect valve for your needs. Remember to always consult a professional for installation and perform regular maintenance for optimal performance.
