The Common Causes of Inconsistent Water Temperature

A burst of cold or hot water in the middle of a pleasant shower can be startling and should be a cause for concern. Fluctuating water temperatures could stem from several different plumbing system components and might signify a more serious plumbing problem. Here are the most common causes of changing water temperatures in your home.

Small water heater

Water heaters come in various sizes. Homeowners should be mindful to choose a unit that fits the size of their home. Unfortunately, when the water heater is too small, the water temperature will indeed fluctuate.

To ascertain whether this is the case, turn on one faucet first and then another water source quickly afterward. If the water temperature changes, it’s very likely the water heater is too small.

Small pipes

It might be the case that the diameter of the pipes in your home is too small. Most home plumbing systems work like a tree. A large pipe carries the main water supply to the home and a branch network of smaller pipes go to each room, including the kitchen and bathroom.

When the water demand becomes too high for the small pipes, the water temperature will be inconsistent. Homeowners will need to hire a professional plumbing service to check for this issue.

Faulty valves

Another common cause for fluctuating water temperatures is faulty pressure-balancing valves. A hot shower that suddenly turns cold when another household member flushes the toilet may indicate a defective valve. But replacing the pressure-balancing valve is no small feat, and homeowners will need help from a professional plumbing company.

Tankless water heaters

If you have a tankless water heater at home, that could be the source of the water temperature inconsistency. One of the advantages of a tankless water heater is hot water on demand; there is no waiting around to jump into the shower. However, one downside of this type of water heater is that cold water can pass through when the burners are off, triggering a temperature fluctuation.

It doesn’t mean that the tankless water heater is damaged; it’s just how they typically work. The good news is that an experienced plumbing technician can make certain modifications to ensure that the water heater is even more efficient.

Inverted temperature knob

An inverted temperature knob is an unlikely scenario, but it’s certainly possible. In the process of new faucet installation, the temperature could be incorrectly placed. Therefore, the hot and cold water might not flow as expected. The temperature regulating cartridges in the faucet will need replacing. Make sure to reach out to a professional plumbing team to fix the problem.

Enjoying consistent water temperatures

Undoubtedly, inconsistent water temperatures can be frustrating. But it doesn’t have to be tolerated. Often, replacing an existing water heater with a bigger unit will do the trick, although tankless water heaters are sure to cause some water temperature fluctuations when they operate.

However, small pipes are a significant issue and might need a larger investment from the homeowners.
