Top Reasons For Abrupt Water Temperature Changes In Your Home

Inconsistent water temperature is annoying and even dangerous. Showering under warm water that turns cold unexpectedly is uncomfortable. And when the water suddenly reaches high temperatures enough to scald, it’s harmful. With that in mind, it’s always crucial to know what is causing abrupt water temperature changes at home.

Fluctuating water temperatures could stem from different plumbing system issues. Our Chula Vista repiping plumber will explain the most common reasons so you can take notes.

Why Is The Temperature Of The Water Of Your House Changing?

You Have a Small Water Heater

You must be mindful when choosing your water heater since each one comes in different sizes. Opt for a water heater that fits the size of your home.

The water temperature will drastically fluctuate if you buy a small heater. Hence the importance of choosing the right size.

To know whether the heater is too small or not, turn on one faucet first and then another quickly. If the water temperature changes, you may have a water heater that’s too small for your house.

Fortunately, you can always ask a professional plumber about the best options for water heaters so you don’t buy the wrong one.

Small Repiping System

Sometimes the diameter of the pipes in your home is the source of the problem. Your pipes can be too small for your house.

Most home plumbing and piping systems work like a tree. The main water supply goes through a large pipe. This pipe works with a branch network of smaller pipes that go to each room (kitchen, bathroom, etc.)

The water temperature may be inconsistent if the water demand is too high for small pipes. You need a Fountain Valley repiping plumber to check for this issue as soon as possible.

Faulty Valves

Another cause for fluctuating water temperatures is faulty valves. Pressure-balancing valves are crucial to keeping your water temperature optimal while doing your laundry, showering, cleaning your house, etc.

Did your hot water suddenly turn cold while taking a shower? Was another household member flushing the toilet at that moment? If the answer is yes, you may have a defective valve.

Unfortunately, replacing a pressure-balancing valve is not simple. You need help from a professional plumbing company, especially if you don’t want to have more problems with your plumbing system.

Tankless Water Heaters

Do you have a tankless water heater? That could be the reason why the water temperature is inconsistent. One benefit of having a tankless water heater is hot water on demand; you don’t need to wat a lot to jump into the shower.

However, the downside of this type of heater is that cold water can go through if the burners are off, changing the water temperature abruptly.

That doesn’t mean the water heater is damaged; it’s just its mechanism. Fortunately, you don’t need to suffer from this issue. You can get the necessary modifications with a Lakewood repiping plumber. This way, your water heater can be more efficient.

Broken Dip Tube

Normal wear and tear in your water tank can change the water temperature. Nonetheless, a cracked or broken dip tube can cause the same issue too.

Dip tubes fill the hot water tank with cold water from the water line. Their mechanism runs the water down to the bottom of the hot water tank. The water tank heats the water and rises it up to the top. The hot water is pumped out of the tank to ensure the tank water is always the hottest.

However, if the dip tube is broken, the cold water could leak into the tank when it shouldn’t, causing abrupt water temperature problems.

Faulty Temperature Knob

While not common, an inverted temperature knob is still possible. The temperature could be wrongly placed when installing a new faucet. Therefore, the cold and hot water might not run as you expect.

You will need to replace the regulating cartridges to solve this issue. We recommend you contact a professional so you get better results.
