    The Ultimate FAQ Guide for Fiberglass Pressure Tanks

    If your household draws its water from a private well, you are likely to experience an unstable water supply and unbalanced water pressure. This is particularly common in households whose water treatment and distribution systems lack pressure tanks. These snags are not only applicable to entities reliant on private wells only, they are also common in enterprises fetching their water from other supply lines. Incorporating a water pressure tank into your water supply line ensures you have a reliable storage system and stabilizes your water pressure. Underneath, we are going to discuss fiberglass pressure tanks, their purpose, and extensive fields of application.

    Figure 1 Fiberglass pressure tank.

    What Are Fiberglass Pressure Tanks?

    They are high-quality water storage tanks manufactured precisely from fiberglass to preserve water and stabilize water pressure within a supply line. The use of top-notch fiberglass to manufacture the tanks ensures that they are immune to corrosion and denting. Compared to pressure tanks made from other materials e.g. stainless steel or aluminum, fiberglass pressure tanks are relatively lighter in weight. This means they are quite mobile and uncomplicated to install.

    A typical water pressure tank is primarily tasked with three roles; preserving or storing water, regulating and stabilizing water pressure as well as alleviating the workload placed on water pumps. FRP water tank are mainly deployed in well water treatment and distribution systems especially in homes using private wells. Their operation is mainly founded on physical working principles.

    Fiberglass pressure tanks operate in tandem with integrated water pressure pumps. Once the pressure tank attains a preprogrammed pressure, the integrated pressure booster pump roars into action or shuts down. At NEWater, we still abide by our admirable tradition of manufacturing first-rate fiberglass pressure tanks for small, medium, and large-scale applications. Our tanks surpass the stringent thresholds set by the relevant authorities to regulate water treatment and distribution products.

    Where Are FRP Water Tank Mainly Applied?

    These tanks essentially preserve and convey water to the required outlet at high pressure or pressure that surpasses the conventional atmospheric pressure. The majority of water treatment applications are necessitated to reserve water to mitigate unstable water supply. In addition, they necessitate high water pressure. Pressurized water tanks essentially fulfill the aforementioned roles efficiently and economically.

    For homes reliant on private well water, pressurized water tanks are a necessity, to say the least. This is because the water pressure is mostly low and infinitely running a pressure booster pump is very costly. However, fiberglass pressure tanks are also quite popular in other varied enterprises and applications. For instance, they are deployed in residential and commercial complexes to store and regulate the water pressure for washrooms and bathrooms.

    In addition, FRP water tank are manufactured in different sizes and capacities consequently permitting their application in industries, commercial entities, and households. In industries, they can be used to store liquids, gasses, and chemicals. The following are reputable enterprises presently utilizing fiberglass pressure tanks.

    • Homes using private well water.
    • Water bottling enterprises.
    • Food and beverages.
    • Petrochemical industries.
    • Restaurants and office complexes.
    • Hospitals.
    • Car wash entities.

    What is the Role of Fiberglass Pressure Tanks?

    Water pressure tanks generally perform three roles; water storage, pressure regulation, and mitigation of pressure booster pump short-cycling. Underneath, we are going to comprehensively discuss each of these roles.

    ●      Water preservation.

    Pressurized water tanks are manufactured in varying capacities often expressed in gallons per day (GPD). They act as a holding unit, which preserves excess water and conveys the water upon demand. With a fiberglass pressure tank, you are assured of constant water supply even when the water supply is low. In households, they are often used to store water for washrooms, bathrooms, kitchens, and other applications in general.

    ●      Regulation of pressure.

    As their name suggests, FRP (Fibreglass Reinforced Plastics) tanks regulate the water pressure of an integrated supply line. They generally increase water pressure above the atmospheric pressure to a preset pressure level. They consist of air, which is consequently compressed by the incoming water. This increases the pressure to a predetermined level.

    In most household pressure tanks, the maximum pressure level is set at 40-60 psi. Once a tap is turned on, water is forced out and it runs out at high pressure. As the water level in the fiberglass pressure tank depreciates, the pressure surges down to approximately 20-40 psi.

    ●      Protection of the water pump.

    Water pressure booster pumps operating in the absence of pressure tanks, switch on and off every time a tap or faucet is turned on. This frequent and successive turning on and off results in excess heat accumulation in the motor. In the end, the motor wears out prematurely thereby necessitating replacement. A fiberglass pressure tank prevents the frequent turning on and off of the water pumps thereby averting the untimely fouling caused by excess electrical heat.

    How Do Fiberglass Pressure Tanks Function?

    Fiberglass pressure tanks technically base their operations on physical properties. Since compressing water is practically impossible, the FRP water tank consists of air, which is subsequently compacted by the incoming water. Compressing more air translates into higher pressure. The compression of air continues until a predetermined pressure level is attained. For instance, most household pressure tanks have pressure level preset at 40-60 psi.

    Once this pressure level is attained, the pressure booster pump stops pumping water into the fiberglass pressure tank. Whenever a tap or outlet faucet is turned on, water leaves the pressure tank at high pressure but the pressure depreciates as the water level drops. When a predetermined minimum pressure level is attained, the pressure pump starts pumping water into the fiberglass pressure tank again.

    In most households, this value is preset at 20-40 psi. To ensure that your water pressure is consistently sufficient, you should set the minimum pressure level to be high enough. For instance, 30 psi or higher in FRP water tank supplying water to dishwashers and water treatment systems. Other water appliances or fixtures necessitate a minimum water pressure of approximately 10 psi. Click on the video underneath for more insight into the operation and importance of water pressure tanks.



    What Are the Varying Types of Water Pressure Tanks?

    Generally, there are varied types of water pressure tanks typically categorized according to construction material, imminent application field, and design. Fiberglass pressure tanks are popular water pressure vessels primarily characterized by their construction material (fiberglass). Underneath, we look at the other types of water pressure tanks.

    ●      Bladder pressure tanks.

    In bladder pressure tanks, air and water are separately held in two distinct chambers. They consist of an enormous air balloon, which is referred to as the bladder. The pressure booster pump is typically activated by the expansion and contraction of the bladder. The separation of air and water means that the addition of air is hardly needed. Compared to diaphragm pressure tanks, they are more durable.

    Figure 3 Parts of a fiberglass pressure tank.

    ●      Diaphragm pressure tanks.

    Diaphragm pressure tanks are characteristically separated on the inside into two compartments by a rubber diaphragm. The diaphragm rises and lowers depending on the pressure tank’s water level. The movement subsequently triggers the pressure booster pump to turn on or off depending on the water level.

    ●      Air over water pressure tanks.

    Air over water pressure tanks are configured in such a way that air sits above the water. In these pressure tanks, the water and air are not alienated by any tangible barrier. Over time, the air is absorbed by the water thereby necessitating air refill.

    What is the Operating Pressure of Fiberglass Pressure Tanks?

    Fiberglass pressure tanks can be preset to operate at different pressure levels depending on the pressure demands of the task at hand. Different tasks typically demand different levels of water pressure. For instance, water softener systems, dishwashers, water treatment units, and laundry machines often necessitate high pressure. These systems often necessitate a minimum water pressure of 30 psi or higher.

    Other tasks, appliances, or fixtures, especially home-based, can operate optimally at lower pressure levels. Fiberglass pressure tanks supplying water for these tasks can operate at pressure levels as low as 10 psi. However, most FRP water tanks designed for well water storage and distribution are often set at 30/50 or 40/60 psi.

    If your fiberglass pressure tank is set at 40-60 psi, once the pressure level hits 60 psi (the cut-off pressure point), the pressure booster pump automatically switches off. As the water is used, the pressure drops and once it hits 40 psi, the pressure pump turns on automatically. When presetting the minimum and maximum pressure levels, ensure that they match the pressure demands of your fixtures or appliances.

    How Long Do Fiberglass Pressure Tanks Last?

    Fiberglass pressure tanks and other water pressure tanks are generally long-lasting products. However, the duration of optimum productivity you reap from a pressure tank depends on numerous factors. The most impactful factors are the tank’s quality, the feed water quality, and cycling. First-rate pressure tanks can serve you exceptionally for up to 30 years while low-quality tanks often last 5 years. You will, however, fork out more money to purchase a high-quality FRP water tank compared to sub-standard ones.

    Low-quality feed water or raw water containing aggressive pollutants like rocks and garnet can also take a toll on certain components of the pressure tank. For example, rocks can tear up the rubber diaphragm used to separate water and air in diaphragm pressure tanks.  To avert this, pretreat the water to extract these aggressive impurities. For the most effective, efficient, and durable fiberglass pressure tanks place your order by contacting NEWater’s engineers.

    What is the Difference Between FRP Water Tanks and Stainless Steel Pressure Tanks?

    Fiberglass and stainless steel pressure are both first-rate water pressure tanks often deployed in homes, industries, and commercial entities to preserve water and regulate water pressure. Despite being utilized to fulfill similar purposes; they are both quite dissimilar. The biggest and most visible dissimilarity is their construction material. Fiberglass pressure tanks are made from fiberglass while stainless steel pressure tanks are manufactured from stainless steel.

    Stainless steel tanks are comparatively heavier due to the dense nature of steel. They are also susceptible to corrosion hence they often necessitate galvanization. FRP (Fibreglass Reinforced Plastics)tanks on the contrary are relatively lighter in weight, extremely resistant to rust, and pretty durable. They are however not as durable as stainless steel pressure tanks. In terms of price, fiberglass pressure tanks are relatively cheaper than stainless steel pressure tanks.

    Figure 5 Stainless steel pressure tanks.

    How Do I Know Which Fiberglass Pressure Tank Size is Ideal for My Application?

    Before purchasing a fiberglass pressure tank, it is imperative that one understands the ideal tank size for his/her application. To calculate the required water pressure tank size, simply base your calculation on the water pump’s flow rate. To be precise, multiply the pump’s flow rate by 4 to establish the ideal size for a water pressure tank.

    For example, if your flow rate is 10 gallons per minute (GPM) multiply 10 by 4. This means that you need a water pressure tank with a 40 GPM storage capacity. This formula essentially applies to bladder and diaphragm water pressure tanks. For stainless steel pressure tanks lacking wafers, the flow rate is multiplied by 9. For example, if the flow rate is 5 GPM, a stainless steel pressure tank with a storage capacity of 45 GPM is needed.
