Things To Know Before Buying A Well Pressure Tank
Technologies used in tanks
If you are someone who has used a pressure water tank before, you might already be knowing that traditional tanks used to have a single compartment design.
The shell of this compartment was made of stainless steel and used to contain both the water and the air. Water pressure was regulated by the pressure of the compressed air on top of it.
However, there was a distinct disadvantage in using this concept. Under the high pressure at the contact area, water will gradually dissolve the air into it.
Thus, the air pressure used to decline gradually over a period, and subsequently, the water pressure was not regulated properly. This phenomenon was termed “waterlogging”.
With time, it became essential to devise a technique that would keep water and air separate, and prevent “waterlogging”. This was achieved by using Bladder and Diaphragm in the tanks.
You will see that most of the tanks being manufactured currently are based on either of these two technologies. Both these technologies separate the air from the water, so that uniformity of the pressure is maintained.
The only difference is that in bladder technology, a rubber bladder is used to hold the water which then contracts and expands based on the pressure it undergoes.
While on the other hand, in the diaphragm technology, a layer of rubber is used to separate the air and water and only this rubber layer moves up and down depending on the tank pressure.
Pressure tanks are now available as “pre-charged” – these tanks are ready to use, having the air sealed inside them and pressurized when they are manufactured in the factory using the diaphragm or bladder technique.
Basic tank features
I am enlisting below a few of the basic features which you should be aware of before you choose a well pressure tank:
All tanks come with an air valve to regulate the air pressure and come equipped with a pressure gauge. Some manufacturers include this pressure gauge in their product, while for others, you would have to buy it extra and get it installed.
Here’s a video that you can check out for more.
It is very important to know the drawdown capacity of the tank. A tank will never be able to fully contain water at its rated capacity. This is because it needs to maintain the optimum air pressure inside.
This is the reason that the actual amount of water a tank can contain will always be lesser than its rated volume capacity.
Drawdown capacity indicates the amount of water the pressure well tank can hold and subsequently provide before the well pump has to start pumping in water.
Higher drawdown to rated capacity ratio implies a more efficient pressure tank.
You will find that the majority of available tanks in the market are made of steel that has a risk of reacting with the water.
Carbon-fiber alternatives are also being used by many manufacturers which comply with national regulations to provide safe and drinkable water.
What is the correct size of the pressure tank for you?
The primary purpose of a pressure tank is to support the well pump and increase its longevity. Hence, the basic information you should employ while choosing the pressure tank is the requisite water demand.
If the pressure tank is smaller for the water demand, then the pump will be under stress. It is always advised that you house a higher capacity pressure tank to avoid putting the well pump under stress.
First, determine the water demand; second, determine the well pump capacity and then find out its flow rate; third, calculate the drawdown capacity of the pressure tank.
I am giving you a few thumb rules to do so:
- If a pump has a flow rate < 10 GPM, then you will have to choose a pressure tank having a drawdown capacity equal to the flow rate multiplied by 1.
- If a pump has a flow rate between 10 and 20 GPM, then you will have to choose a pressure tank having a drawdown capacity equal to the flow rate multiplied by 1.5
- If a pump has a flow rate > 20 GPM, then you will have to choose a pressure tank having a drawdown capacity equal to the flow rate multiplied by 2.
Now that you know the basic features that you should look for in a well pressure tank, we will talk about the commonly asked questions in the next section. They will provide you with a better understanding and help you make an educated decision.
Frequently Asked Questions
Q. How do I check the pressure in the tank?
You should always check the pressure every 2 months. You need to first turn off the pump and then drain the tank. Next, remove the cap over the air valve.
If there is water leakage at this stage from the valve, then the tank needs to be replaced. You can then check the pressure using the pressure gauge.
Q. What is the average lifespan of a pressure tank?
Depending on the quality of the materials used during manufacturing and if regular maintenance is done, then a pressure tank should last at least 10-15 years.
Q. Can I install the wall pressure tank outside?
Not all components of a pressure tank are built to withstand extreme weather or high-temperature variations, it is always suggested to have the pressure tanks installed indoors.
Q. How do I change the pressure?
You can use an air compression system or a bicycle pump to add air, if necessary. To release air pressure, you can use the air valve cap.
The pressure should be maintained at 2 psi lower than the pressure switch pump cut-in setting.
Q. What is the ideal size of a well pressure tank?
A large pressure tank implies large storage capacity, which is better for increased longevity of the well pump.
A larger pressure tank also implies a higher cost of purchase. Hence, choose what is optimal for you.
Yes, fitting accessories are available with which you can link together multiple tanks. With each linked tank, the overall drawdown capacity of the tank system is increased.
So when it comes to choosing the best well pressure tank, Wellmate WM-9 pressure tank stands out from the rest. It is an early adopter of the fiberglass technology and is metal-free.
It provides a very light and corrosion-free alternative, and the water has no risk of being contaminated by the metal. The tank is made of finest material, and is durable enough to last for the years to come.
While choosing a well pressure tank, we will highly recommend you check the water demands in your house, the flow rate of the pump and then determine the capacity and model that will suit you the best.
