How to Size a Pool Pump for Your Home Pool

More often than not, swimming pool owners make the mistake of buying larger pool pumps than they actually require. This leads to high operating costs and straining on their pool filters because of too much pressure. They do this because they lack the appropriate information regarding what to consider before buying them. Some important questions need to be asked before choosing and buying a swimming pool pump. These are:

1. What size pool pump do I need?

2. How big is my pool?

3. Is it above-ground or in-ground?

Factors to consider

1. Size of the pool

The size of the pool directly determines the pump size you need. It is measured in gallons and can be calculated using the following formula:

Length * Width * Average Depth * Multiplier

The multiplier for round or oval pools is 5.9 while for rectangular, square or free-form pools is 7.5

The average depth is calculated by summing up the shallow end depth and deep end depth then diving the sum by two. It is important to note that all these measurements are in feet.

The resulting value is what determines the pump size you need. The best practice is to circulate the water through the filters at least three times daily meaning that the pump should be able to pump all the pool’s water in 8 hours. Therefore, the size of the pool (in gallons) should be divided by 8 in order to get the flow rate per hour then divided by 60 to get the flow rate per minute. For instance, a rectangular pool measuring 50 ft by 20 ft with a deep end depth of 8ft and a shallow end depth of 4ft should have a pump with the following flow rate

20*10*(8+4)/2*7.5=9000 gallons

9000/8=1125 gallons per hour

1125/60=18.75 gallons per minute (GPM)

This means that you will need a pump with a flow rate of 18.75 GPM.

2. Pump speed

There are three types of pool pumps categorized according to speed. These are

•        Single speed pumps

This is very common and it runs continuously at one speed depending on its motor’s horsepower. It is highly inefficient because of constantly running at one speed (which is usually high speed) while you might require different speeds to suit your filtration needs or turnover time.

•        Dual speed pumps

Dual speed pumps give you the flexibility of choosing between high speed and low speed. High speed is used mostly when cleaning the pool or when there is a major issue while low speed is used on normal times (when the water is generally clean and requires slower turnover) saving on energy costs.

•        Variable speed pumps

This is the most efficient pool pump because it has a permanent magnet motor (similar to the ones used in electric cars) which has less friction as compared to the induction motors on the single and dual speed pumps. It allows you to set the flow rate at any speed giving you the most flexibility in cleaning your pool. Though expensive, this is the best type of pool pump and is recommended for its flexibility and efficiency.

3. Above-ground or in-ground pool

The type of pool determines where your filter will be located, which then determines the pump you need. If the filter intake is positioned above the pump, you will need a top-mount pump. On the other hand, if the filter intake is on the same level as the pump, you will need a side-mount pump.

4. Filter size

A filter’s size also determines which pump to buy. A large filter requires a large pump while a small filter requires a small pump. However, it is better to have a pump with a max flow rate that does not exceed a filter flow rate just to keep the system safe. The opposite however would be catastrophic because the pump will destroy the filter.

How to size a pool pump

A pool’s size greatly determines the pump size. However, other factors also contribute to ultimately determining the pool pump size. These include the resistance from the filters and plumbing. Water passage through the filter produces resistance. As the filter gets used for a long time, it gets clogged with debris which further increases its resistance.

Similarly, the plumbing around the filtration system might include many bends or a large head which causes a significant resistance to water flow. Hence, it is recommended to get a pump with a slightly larger flow rate to cater for any form of resistance and give you the required turnover time.

How to choose a pool pump

Popular brand pool pump are the safest bet because of their durability. A good example would be Onga pool pumps such as this specifically designed Onga Pantera Ppp750 pool pump. Onga pool pumps are high quality pumps which are known for their reliability and exceptional performance.

How to buy a pool pump

With all the information above, it is time to buy the pump. Many manufacturers provide details of their pool pumps on their websites and this is a good place to compare the pumps specifications with the specifications you want.

In this case, Onga pool pumps are clearly listed and classified as filtration and specialty pumps on their website where you can compare specs then purchase from their dealer shops.

5 Reasons Why Quartz Worktops are So Popular over the Years

Quartz worktops have become the most popular type of solid kitchen worktop. There are a significant number of new homes being built with quartz kitchen worktops. They portray the classic look and call for zero maintenance. Thus, you get the desired look for your kitchen with this one.

Responsibilities of a cardiologist

Human beings are confronted with various health issues. This has led to the emergence of health specialists in various domains as they could tackle all issues with a degree of ease. Issues are bound to spring up with your blood or the heart. If such an issue arises then you would need to get in touch with a cardiologist.

They are able to deal with various issues and this includes heart diseases, hypertension, and heart murmurs to name a few. As a heart specialist one has to deal with preventive mechanisms, how to diagnose and treat heart conditions as well. From time to time they may be required to perform surgical procedures as well, though it could be limited to minor ones.

Preventive medicine

It has to be said that heart problems tend to be chronic and they do exist for a long period of time. For this reason a heart specialist works hard on preventive medicine so as to neutralize and lead to a progression in the disease. More often than not a cardiologist needs to be conducting a physical examination along with an interview of the patient so as to predict if there is any issue with the heart. It would also be necessary to prescribe some form of medications with regards to patients and also advice on the lifestyle. Hereby the heart condition of the patient is improved and sustained.

Diagnostic testing

One of the main tools which a cardiologist uses is an ECG. With the aid of the instrument it is figured whether the heartbeat of a patient is normal or not. Then the cardiologist is going to interpret the results. Coupled with the fact that the results of the blood along with urine need to be interpreted as well. In the midst of this the stress test is also conducted and then the results are reviewed. With the aid of cardiac cathetezation tests an understanding on how the heart is functioning is found out as well.

Electrophysiology

It works out to be a cardiology speciality and the onus is to find out more about the rhythm of the heart. A peacemaker is planted on to the patient with the help of a surgical procedure and this is done in a brief manner. In this procedure a shock is given to the heart so that it goes on to function in a normal manner.

Other roles

Just like other doctors the cardiologists go on to perform varied administrative work. It would mean updating the records of all patients and this would mean preparation of insurance forms as well. Another important point of consideration is that cardiology is an evolving field and keeps on changing. It is of fundamental importance that a cardiologist keeps up with the changes in this field and this is done through education and training.

If you are considering the best cardiac surgeon in India then it is suggested that you undertake a little bit of research. The internet is the best place to find more about them.

Add an Eco-friendly Touch to Your Kitchen

Fortunately, more and more people are taking steps toward making their homes energy efficient and living their lives in a way that’s responsible toward the environment. Whether your goal to live a more eco-responsible lifestyle is only starting to take shape or you’ve been striving to live this way for a while, there are always improvements to be made. The kitchen is the heart (or hearth) of the home, so our approach to how its functions holds not just practical, but symbolic value. In light of that, let’s have a look at some simple changes you can make in your own kitchen to make it more eco-friendly.

Conserve water

So much water gets wasted in the kitchen sink, and leaking faucets are a major contributor. It might look as if the drips are miniscule, but they accumulate. Always check if your faucet is leaking and fix the leak – you’ll be likely to find a decrease in your annual water bill as well. If it’s time for a new one, invest in a WaterSense-labeled faucet that is low-flow and thus doesn’t use excessive amounts of water.

Eliminate plastic

…as much as possible. It might take some effort and time to get used to, but it’s not that difficult, and it’s definitely worth it. Here are some ideas:

• Use wooden cutting boards instead of plastic boards and mats. Wood types such as bamboo also naturally reduce the growth of microbes.
• Use a reusable shopping tote for groceries – one that is made from cotton, hemp, or any other natural material. Wash it frequently and hang it somewhere visible so you don’t forget it on your way to the store.
• Substitute plastic food containers with eco-friendly containers made from glass, silicon, or metal. Use reusable beeswax wraps instead of plastic food wraps as they do the job just as well, and can be washed and reused. If you buy some groceries in plastic containers, wash the container once it’s emptied and reuse it for food storage.

Illuminate your workspace efficiently

The best thing to do is to invite plenty of natural light into your kitchen, so that you can see properly without using artificial lighting an you get that bright, open, Pinterest-worthy space. In that case, you’ll need adequate window furnishings to control the amount of sunlight that comes in on hot days, so you don’t have to use air conditioning. Otherwise, invest in energy-efficient lightbulbs for your task lighting – LED lights use less energy than any other form of lighting, and this will show on your electric bill as well. Install dimmer switches so that you can use them on occasions when you don’t need full-on lighting.

Make an indoor compost bin

You might be using your garbage disposal frequently as they really are convenient, but they’re not quite eco-friendly. Make your own compost bin (you’ll see that it’s not difficult at all!) and make a point of adding to it all the vegetable scraps, leftovers, and organic matter from your food preparation. You’ll save on water and energy and you can use the compost matter to nurture your plants. Speaking of plants, here’s an extra tip: grow an herb garden inside your kitchen. It will add a touch of green to the space and also purify the air, plus you’ll be incorporating a lot of healthy herbs into your meals. And the smell in your kitchen will be better than any artificial air freshener could ever hope to be.

Invite these little changes into your kitchen and enjoy the benefits. As time passes, you’ll be implementing more and more eco-friendly tricks, and you’ll find it’s not that difficult at all. A green kitchen is the start of a green home.
