Imagine what will happen when you are enjoying a hot bath in a bathtub, but suddenly the water becomes cold.
Why Does My Bathtub Run Out of Hot Water? Your bathtub can run out of hot water leakage, excessive use, and accumulation of minerals. In addition, a leaking tub, an old heater, and a damaged dip tube reduce the hot water supply.
It is a significant part of utility bills, so be careful and identify the cause of its reduced functioning. However, you should not compromise on its working when you pay a lot of money to get hot water.
Excessive use
Everyone tries to use hot water to do every house chore which involves water.
For example, you need it to wash the floor and clean kitchen dishes. Sometimes everyone uses it at the same time, which reduces its supply.
It is a common practice that it is connected to other household systems, so they take their share, and the hot water supply divides into every system. For example, you use it in the laundry and to wash the dishes in the kitchen.
It is better to set a usage time like you should do laundry when no one is taking a bath, and you should use it in the dishwasher when its other connected system is not activated.
It is better to limit the bath time when you face this problem to prevent any unfavorable conditions.
You can set a bathing schedule to use its hot supply in the bathroom at a specific time to avoid its shortage.
Check the tag on its tank and call the professional if it needs replacement. It is better to use its thermostat level because it can happen when it is not operating effectively.
It can be at a lower temperature, so you should keep it at an optimum high temperature to enjoy the hot bath.
Old water heater
Every appliance has its specific age, and it can work efficiently up to this age. You can call it its working age for understanding because it does not work correctly beyond this age.
It shows signs like knocking plastic sounds and reduced hot water duration when it crosses its working age. Most heaters can work effectively for 8 to 15 years according to their quality and maintenance.
A good quality one can last even for more than 15 years when you use it correctly and arrange a maintenance check regularly.
Several companies mention their manufacturing and expiry date on their surface so you can easily get an idea of their working age.
You can ask the manufacturer of your heater if there is no date and expiry year mentioned on its body. You can fix issues like broken gas valves by checking them regularly.
It happens in gas-operated heaters, so you should keep in mind to check if it’s broken when you run short of hot water. You can clean sediment buildup on regular cleaning, which significantly affects its functional capability.
Accumulation of minerals and rust
Water contains several minerals, which can affect the supply of hot water. They are present in hard water, which contains them in bulk quantity.
Therefore, you have to read the user manual carefully because it is necessary to follow the instructions to avoid such issues.
Check the proper flush time gap on this manual for maintenance. A good quality heater needs the system flushed once a year. These minerals from the hard water start accumulating at the base of its tank, which is not a good sign.
They interact with its heating element and become the cause of less hot water availability. This is because the heating element has to heat the water, which is present at the bottom of the tank.
These minerals and sand particles are also present at this place, so heating elements start to make them hot.
It divides the heat into water and sediments, which causes this issue. Its best solution is to clean the base and remove all sediments from this place.
It can result in flooding on your floor if you do not have the expertise to fix the issue, or you can take help from a professional.
Damaged dip tube
Sometimes you do not find any visible reason for the hot water shortage in your bathtub, so you have to check its inside chamber.
The problem also occurs when the cold supply mixes with the hot water and decreases its temperature.
A faulty dip tube affects the hot water flow, and you run short of its supply. It is a kind of water carrier which carry cold water and bring it to the bottom for heating purposes.
Sometimes it becomes corroded, which reduces its working efficiency. It can also lose its capability due to the leaking of some of its components.
Your heater will not work in its damaged condition or its absence. They start to break if the hard water is entering into this chamber.
You can get an idea from the continuous knocking sounds of plastic material. It is an indication that its plastic is breaking and needs immediate repair.
You can get professional assistance from a certified person, but it will cost much. You can remove it by removing its screws, which are present at the top surface of the cold-water supply tank.
You have to replace a damaged dip tube in most cases, so it will be an extra burden on your budget. It ranges between 12$ to 160% according to the quality and working efficiency.
Leaking bathtub
Sometimes you wonder because there is enough hot water supply from the faucet, but you get little water in your bathtub. It happens quickly, and water does not accumulate in the tub.
Its common reason is the leaking of the bathtub because it does not allow water to accumulate in it. Sometimes it leaks with more speed from the tub than its supply speed from the faucet.
You should check it from all sides to ensure it is not cracked or broken. The heater can also leak in some cases, and water accumulates around it.
You should immediately address this problem because it takes a lot of effort to tolerate less warm water in the bathtub and to clean the floor every time you take a bath.
