How do I adjust the water temperature on a double sink wash basin faucet?

Aug 07, 2025

Hey there! As a supplier of Double Sink Wash Basins, I often get asked about how to adjust the water temperature on a double - sink wash basin faucet. So, I thought I'd share my knowledge in this blog post.

First off, let's understand the basic types of faucets you might find on a double - sink wash basin. There are two main types: single - handle and double - handle faucets. Each type has its own way of adjusting the water temperature, and I'll break it down for you.

Single - Handle Faucets

Single - handle faucets are super popular these days because they're easy to use. You can control both the water flow and temperature with just one lever.

How it Works

The single lever on these faucets is connected to a cartridge inside the faucet body. The cartridge is like the brain of the faucet, regulating the mix of hot and cold water. When you move the lever up or down, you're controlling the water flow. When you move it left or right, you're adjusting the temperature.

Adjusting the Temperature

  • Hot Water Side: If you want hotter water, simply move the lever towards the left (in most cases; some faucets might have the opposite setup, but it's usually marked). As you move the lever further left, more hot water will mix with the cold water, raising the overall temperature.
  • Cold Water Side: To get colder water, move the lever towards the right. This allows more cold water to flow through, reducing the temperature.

However, sometimes you might find that the maximum hot or cold temperature isn't what you'd like. In that case, there's usually an adjustment screw or a temperature limiter inside the faucet. You'll need to remove the handle to access it. Use a small screwdriver to turn the screw or adjust the limiter according to your preference. But be careful not to over - adjust it, or you might end up with scalding hot or ice - cold water.

Double - Handle Faucets

Double - handle faucets have been around for a long time and are still a classic choice. They have one handle for hot water and one for cold water.

How it Works

Each handle controls the flow of either hot or cold water independently. By adjusting the position of each handle, you can control how much hot and cold water is mixed together at the spout.

Adjusting the Temperature

  • Hot Water Handle: Turning the hot water handle clockwise will usually increase the flow of hot water. The more you turn it, the hotter the water will get.
  • Cold Water Handle: Turning the cold water handle clockwise will increase the flow of cold water. If you want colder water, open the cold water handle more and close the hot water handle a bit.

Finding the right balance between the two handles takes a bit of practice. You might have to make small adjustments to both handles until you get the perfect temperature.

Troubleshooting Temperature Issues

Sometimes, even after adjusting the handles, you might still have problems with the water temperature. Here are some common issues and how to fix them:

Inconsistent Temperature

  • Check the Water Heater: If the hot water temperature is fluctuating, it could be a problem with your water heater. Make sure the thermostat on the water heater is set correctly and that the heater is working properly.
  • Mineral Buildup: Over time, mineral deposits can build up inside the faucet, affecting the water flow and temperature. You can use a descaling solution to clean the faucet aerator and the cartridges. Simply soak the parts in the solution for a few hours and then rinse them thoroughly.

No Hot Water

  • Hot Water Supply Valve: Check if the hot water supply valve under the sink is fully open. Sometimes, the valve can accidentally get turned off.
  • Water Heater Problem: If the valve is open and you still don't have hot water, there might be an issue with the water heater. It could be a faulty heating element or a problem with the thermostat. You might need to call a professional plumber to fix it.
