Why does my water get hot then cold then hot?
Fluctuations between hot and cold temperatures indicate that only the upper water heater circuit is working. This thermostat supplies power to the upper heating element, and diverts power to the lower element once the ideal temperature is reached in the water at the top of the tank.
Why does my hot water go cold after a few seconds?
If you’ve noticed that your hot water is suddenly turning cold after a very short amount of time, the most likely cause is a broken dip tube inside your hot water heater. And when that happens, you’ll get lukewarm water delivered to you soon after you start using hot water.
What causes hot water to fluctuate?
If your water temperature fluctuates, the pressure-balancing valve might be to blame. Your pressure-balancing valves open and close depending on your water flow in your plumbing system. If cold or hot water levels drop, a broken pressure valve could cause a drop in water pressure.
Why does my hot water run cold then hot?

Why does my shower turn cold after a few seconds?
After a few seconds, say 10-20, of decent hot water, it turns completely cold for another 10-20 seconds, even if I max out the control. Then it returns to normal hot water and stays that way until I’m done. So what accounts for that intermediate burst of cold water? No one else is in the house using hot water, so that’s not it.

How does the combi boiler hot then cold hot water problem?
Just been reading a few posts, basically I have a combi and the hot water goes hot then after say 20 seconds it gets cooler and runs cold, then runs hot again and carries on this way. How does the gas valve settings cause this fault? Is it because the gas valve canot modulate properley??..
Why does my hot water heater keep running cold?
This problem happens because the heat exchanger (the part that actually heats the water) takes a while to warm up. Before it fully warms up and starts heating the water, you get a short run of cold water. Then, once the heat exchanger heats up, you get a steady flow of warm water. So where does the initial blast of hot water come from?
Why does my hot water have a Rusty look to it?
If your plumbing is using galvanized pipes, they could corrode over time. However, if the plumbing consists of copper or plastic tubes, then you should look for the cause somewhere else. Pipes can also rupture, so dirt can slowly get inside, contaminate the water, and making it look rusty.
Why is my hot water discoloured from the tap?
If the discoloured water is only coming from the hot taps, it’s likely you have a problem with your hot water system rather than the plumbing more generally. Most likely, it’s corrosion – especially if your unit is getting old. If so, consider calling your plumber and exploring your options for a new hot water system.
