Why do I Have No Cold Water?

When your water heater stops working and you have no hot water, it can be a major inconvenience and not having cold water can be just as alarming. When it comes to not having hot water, the culprit is almost always your water heater; however, if you have no cold water, the cause may not be quite as easy to diagnose. Most homeowners don’t even realize that having no cold water happens, but it does. We are going to help you solve the mystery of, “Why do I have no cold water?”

Why do I Have No Cold Water?

When it comes to using your Phoenix home’s water, finding the right temperature is one of the most important things. It doesn’t matter if you are showering, washing dishes, watering the gardening, or something else; having water that is too hot or too cold can be undesirable and could be a potential safety issue.

If you have no cold water, the water in your home may be too hot. The EPA recommends a hot water temperature setting of 120°F for health and safety. If your cold tap isn’t working, you may not be able to avoid using water that is too hot for you and your family.

Why do you have no cold water, what is causing the issue? To find out what has created the problem, you need to troubleshoot. We have provided some steps below.

  1. Try Other Faucets in Your Home. Step one to diagnosing why you have no cold water, is determining if the problem is only in one faucet or your entire home. Go around your house and check other faucets for cold water. If you have discovered that the problem is limited to one faucet, there is likely a specific issue with that particular faucet and you can move to step three. If the issue is happening throughout your home, follow the below next step.
  2. Check the Main Water Supply Line Shutoff Valve. One of the most common reasons that people find themselves without cold water is because the shutoff valve was turned off. The main shutoff valve allows a full flow of water through the pipe when it’s open. Turning off this valve (by turning it clockwise) cuts off the water supply to the entire house and can cause only hot water, or none at all. Confirm this valve is open.
  3. Check the Individual Shutoff Valve. The plumbing to each sink in your home is equipped with individual shutoff valves, which allow the water supply to be stopped locally without affecting the rest of your house. Similar to the main water shutoff valve, confirm that it is open by turning it counterclockwise.
  4. Call a Phoenix Plumbing Expert. If you have tried all of the steps above and still can’t determine why you have no cold water, you may have a larger issue and it’s time to call in a professional. There could be a kink in the water lines, a leak in your plumbing, or something else may have gone bad.
