Are you a pool owner? Are you concerned about the maintenance of your pool? If yes, you need to focus on the quality of the pool equipment. One of the essential pieces of equipment is the pool valve which has a significant role in pool plumbing.
It helps in the circulation of water and does not allow dirt-laden water to stay stagnant. Instead, it forces the dirty water to be washed out of the pool and promotes water sanitation.
So, to ensure the proper functioning of the pool valves, you need to have a clear idea of its performance, its method of functioning, and the best brands that offer the best pool valves that are efficient.
What Are Pool Valves And What Do They Do?
Like any other valve, a pool valve is also a machine that pumps fluid and controls its movement, and automatically allows its movement in a direction. In the case of a swimming pool, the circulation of water is controlled by using a similar valve known as a pool valve.
In other words, it may be said that the pool valves are the devices that guard the water and allow it to move inside or outside the pool and through the pool accessories.
Valves are the gatekeepers of water that move it in and out of your pool while also moving it through your pool accessories so that every component is doing its job to the fullest.
For keeping the pool clean, hygienic, and healthy, it is mandatory to circulate the water and pump out the used unclean water.
The movement of water prevents the debris from sediment formation, and thus, pool filters can work due to the efficient performance of the pool valves. Without the valves, insects, microorganisms, algae, and even mosquitoes would start piling up, making your pool a swamp.
For proper circulation, the water needs to move in the right direction to filter the water. In case of malfunctioning of the valve, the backflow of the unclean water would pollute the pool.
To ensure cleanliness and hygiene in your pool, you should have a clear perception of the quality of the valves that connect the pool equipment and the points where each device is connected to the other.
Apart from the flow of the water and the function of the filters and skimmers, you should also know about the valves that lead to the pool heater, the importance of the changing valves, etc.
Types Of Pool Valves
In the market, pool valves are available in a myriad of shapes and sizes. Each type of valve has a significant function. The various types of pool valves have been discussed below:
If you are searching for valves for your pool, the first type of valve you need to find is a multiport valve. It is essential for backwashing of water, filtering the pool, and fr getting rid of the wastewater, especially if the water is being manually vacuumed or drained out of the pool.
Another special purpose of this multiport valve is that it allows water circulation without filtering it. This becomes necessary while adding flocculant in the pool to clear the water’s cloudiness. After adding this flocculant, it must be mixed or circulated well in the pool to function precisely. In this case, you need the water to be circulated in the pool but not filter out.
Moreover, this multiport valve shall be a great help for you if you dwell in an area experiencing chilly winters. In winters, when the water freezes, the frozen water badly affects the pool water lines.
Using this type of valve blocks those lines preventing the entry of water into those lines, so freezing water can not harm the pool equipment in the winter.
These are also known as butterfly valves because of the flap-like movement of the values resembling a butterfly’s wings. These vales comprise giant flaps that open and close to allow and block the pipe to stop the water flow completely.
On opening the valve, the flap shifts towards its side, thereby unblocking the pipe. Generally, in the pool, the 2-way valves are used that possess a large-sized lever at the top. Twisting the lever opens or closes the valve.
A 3way diverter valve is also available, which posses one outlet and two outlets along with a flap for blocking the water. Although its function in a similar manner yet the flap is a bit complicated.
In this case, the valve can be used for opening r closing the flow of water or allow water to move through any one of the two outlets or allow water to enter through both the outlets.
It is advisable to handle the values carefully and open or close them slowly. If you exert excessive pressure to close this valve, the water pressure may inflict damages on the valve and the pipes in case of more significant pressure.
These are one-way valves that are used in the pool plumbing to evade the backflow of water. These are also known as non-return valves, and they function using gravity to stop the backflow of water.
When the pump in the pool is turned off, it becomes necessary to guard the outlet so that the unclean water may not infiltrate into the pool. That is why check valves are used to check the backflow.
Based on the different types of pool equipment, check valves are utilized in the pool. The use of it is explained in the context of the following pool accessories:
Often in pool water, features like a fountain or a waterfall are seen. When these features are installed, their water source is set as the water from the pool itself, or any reservoir is set for the feature to get the water supply.
If it runs on the pool water, then this valve is not needed, but in the case of a reservoir, the check valve must prevent the used water from draining into the pool after the fountain or waterfall is turned off.
You need a salt chlorinator or chlorine generator to add chlorine into the pool to maintain chemical balance. When the water moves through the circulation or filtration system, this device adds highly concentrated amounts of chlorine into the water.
This contributes to the sanitization of the pool water. However, if the check valve is not added to the chlorinator express, then the backflow of the chlorinated water into the pool equipment would negatively affect them.
The pool accessories can not withstand this high concentration of chlorine, and they lose their efficiency. Thus to avoid such a situation, check valves are necessary.
You may skip this part if you already have a regular heat pump. This is because both pool heaters and standard heat pumps have diverter valves. Solar pool heaters, however, really need check valves to function.
Solar pool heaters warm the pool water in sunlight, usually positioned on your roof for optimal coverage. But if you turn off the pump, the water is simply going to splashdown, thanks to the laws of physics. This is where a check valve can stop this backflow and retain the water on your roof where it needs to be.
If you have to do everything manually, like handling the valves, twisting its levers to open or close them, it will become a tiring task for you. Instead, you can resort to the use of valve actuators which can be installed, and the connection to a pool control box with buttons on it will enable controlling it efficiently with the push of a button.
Why spend half your day walking from pipe to pipe, twisting levers, and opening and closing valves when you could set it and forget it? You can instead work with little contraptions called valve actuators.
After you’ve successfully installed the valve actuators where you need them, you can wire t to the pool control box with a panel of buttons. Now, all you need to do is push a button to divert water or turn on your waterfall.
When To Replace A Pool Valve?
This brings us to the vital question that when you should change the valves. You must know that just like other pool equipment, you have to change it after a certain time to replace the brittle and old parts of the device.
Since the valves do not last forever, you have to be vigilant and keep checking whether it has gone through wear and tear and needs replacement. It is essential pool equipment and thus must be changed before any malfunction jeopardizes the pool’s cleanliness.
