The use of water tanks includes issues, tips, and challenges. Alongside the things like the algae growth in the tanks, heating the tanks contents, water overflowing from the tank is one of the events that consumers are afraid of. In general, water overflowing from tanks causes the water wastage and damage to the tanks. Usually, experts recommend that you never fill the tanks completely and always leave a certain amount of space in the tanks empty to prevent them from overturning. We want to prevent this from happening by investigating the causes of water overflow from the tank in this article.

 

What does Water Overflow Mean?

First of all, we should mention what the water overflow from the water tank means and what its consequences are. Generally speaking, water overflow from the tank means the tank overfilling and water coming out of the tank lid or the overflow pipe. The occurrence of this in the first place causes a significant amount of water to be wasted that can impose significant costs on the consumer. Also, it should be noted in the second place that filling the tanks completely can cause them to tilt and damage them. Consequently, it is better to always leave a part of the tank empty. Of course, it is worth noting that it is not possible to use the full capacity of the tank and the amount of water kept will be lower than the nominal volume of the tank. You can study the list of dimensions, size, and weight of polyethylene water tank for more information in this field.

Reasons for Water Overflow from Tank

In general, there are two events that can cause water to overflow from the tank or supply. These two events are:

Floater failure

Water returning from the outlet

We will describe both events and conditions of occurrence of each to investigate the reasons for water overflowing from the tank in the following.

 

Floater Failure

A floater is a device whose function is to keep the water level in the tank constant. As the water level decreases and the floater goes down, the valve is opened, and when water enters the tank and its level rises, the floater returns to its previous state and the valve is closed. Failure of this part can lead to failure and closing of the valve. The floater failure can have various reasons, which will be mentioned at below:

 

Gasket Failure

It is better to put enough Teflon tape (PTFE) around the gasket threads before the float installation  so that the floater can be fixed well by turning a little in order to prevent the failure of gasket or plastic equipment, which are responsible for preventing the entry and exit of water.

Ball Failure

Sometimes it happens that the ball is punctured and the ball no longer floats on the water surface when water enters it, and consequently, the water surface is not determined accurately. This problem is usually solved by replacing the ball or finding the ball hole and repairing it, and there is no need to repair all the floating parts.

 

Solids Clogging in the Floating Valve Location

  Sometimes, the float function is disturbed when solid particles get stuck in the floater valve place. This problem is also solved by opening the floater and cleaning it.

Lack of Proper Regulation of Float

Lever length can be made shorter or longer in some floaters. This feature makes it possible to increase the ball power to overcome the pressure of the water entering the tank. Improper floating regulation can cause the water in the tank to overflow.

Floater Installation in a Slanted Way

  The floater should be installed in a way that it is on the line perpendicular to the tank bottom. If the floater is installed obliquely, the pressure applied to the ball will not be transferred to the valve correctly. Consequently, the valve will not be closed at the right time.

Water Returning from the Outlet

Continuing to investigate the causes of water overflow from the tank, we find out that if the one-way valves do not operate properly, then the water will return to the tank from the place of these valves and cause the water to overflow from the supply (tank). To find out whether the one-way valves have a problem or not, you must close the water inlet valve of the building from the city network. Then, you should supply water to the building using a pump and water in the tank. If the water still overflows from the supply in these circumstances, the problem is with the water inlet floater of the tank. But if the problem of water overflowing from the tank was no longer observed by doing this, then you should know that the problem is caused by the installed one-way valves. Consequently, the damaged valves must be identified and replaced.

 

Conclusion

Using water tanks brings challenges. Among these challenges, we can mention the algae growth in the tanks and heating of the tanks and their contents in addition to water overflowing from the tanks, each of which can be solved. As we have mentioned in this article, we notice two events by investigating the reasons for water overflowing from the tank and when they occur, the water overflows from the tank. These two reasons are mentioned as follows:

Floater Failure

Water Returning from the Outlet

It is better to consult a facility expert if you complied with the mentioned items completely and you still faced the water overflowing from the tank.
