The Content Of The Article:

I work in a boarding school and in one of the kitchens we never had cold water, it stays warm or hot. Our plumbing maintenance has changed the mixer but nothing works. Do you have an idea... or a track to follow?

The reasons that make cold water network lukewarm remains are multiple. For a precise analysis, one should at least know the design of the installation.
This problem may arise from an unexpected mixture of hot and cold water in the network or at the level of a heat exchanger, cold water pipes too close to a heat source (boiler, heating pipes or hot water, etc.), a bad water / cold water seal at the level of mixers (but this cause seems to have been ruled out). Normally, a plumber / heating engineer must be able to remedy this problem by having access to the entire installation.

Why does a cold water system remain lukewarm?

FAQ - 💬

❓ Why is my cold water lukewarm?

👉 There could be a wide range of culprits causing your cold water to run warm, but the most common include too much water pressure, closeness of pipes, recirculating plumbing, improper installation of heat traps, water expansion tank valves, and even something known as the heating effect.

❓ Why is my boiler only producing lukewarm water?

👉 Your problem could lie with a thermostatic sensor, which is cutting out the flame before the water has reached the correct teperature. Or more likely the heat exchanger is scaled and the heat transfer from the fame is not being able to penetrate through properly.

❓ Why is my cold water not very cold?

👉 cold water lines are rarely insulated for energy efficiency, and so in hotter temperatures the air temp can affect the water temp. Sometimes pipes are run in attics, crawlspaces or basements that aren't conditioned. Sometimes they're run in un-insulated or under-insulated walls. Any of these factors could be at play.

❓ What causes lukewarm water?

👉 As water collects inside your hot water heater to be heated, it's common for debris in the water—like sand, dirt, and minerals—to settle at the bottom of the tank. As the particles collect on the bottom of the tank, the water heater can't effectively heat your water, resulting in lukewarm water only.

❓ Why is my cold water not working but hot is?

👉 If no cold water is a widespread issue throughout the home, it's possible a shutoff valve in the main water supply line may have been turned off accidentally. If that's the case, you can simply turn the valve back on and get back to showers as normal.

❓ How do I make my water colder?

❓ What causes low water temperature?

👉 Over time, minerals in the water can build up at the bottom of the water heater tank where the burner is located. This causes a gradual reduction in heating efficiency that will make the water heater work harder and eventually resulting in less hot water. Flushing the tank annually will prevent sediment build up.

❓ What temperature should cold tap water be?

👉 When removing grease, it is critical to keep the water temperature at a cool 46C or 48C, but at a risk of overheating. Cold water systems should be kept at temperatures below 20 degrees Fahrenheit, and temperatures have ranged from 6 degrees Celsius to 25 degrees Celsius between 2008 and 2019.

❓ Why is my cold water tap running slow?

👉 If your valves are open all the way and you're still experiencing slow water flow, then the cause might be a clog. The first place to check is the aerator. The aerator is the cap on your faucet where the water comes out of. It has a screen and, over time, sediment gets caught in it, which impedes water flow.

👉 If you find that your hot water is coming out lukewarm, not hot, don’t ignore it any more than you’d ignore hot water that is suddenly too hot. It’s important to find the reason for the temperature change, so you can get it fixed. Here are 6 common reasons why your hot water is lukewarm. 1. You Have a Tripped Breaker

👉 If you get cold water in the morning, chances are you’re touching the water that was left sitting in the pipes. If it’s still cold after a few seconds, it could be because the water heater burners have yet to ignite. And they won’t ignite until you call for hot water, which is usually the first hot shower of the day.

👉 Recirculating plumbing can also cause problems with hot and cold water. Finally, pressure problems can affect the balance of hot and cold water in the plumbing, pushing water into the wrong pipes. If your cold pipes are poorly insulated, they might warm up simply due to the residual heat of the ground they’re running through.
