Install Inground Pool Pump and Filter

If you need to install an inground pool pump and filter, this article will give you all the vital information you need. A professional technician will find it almost too simple to both select and install a pool system. However, the entire task can be rather challenging for beginners who don’t have the slightest clue of where to begin.

If you are looking to save a few bucks by installing the pool system by yourself, then understand that the task will need plumbing and electrical connections. With the help of this article, the task will be simple and straightforward.

However, before we begin the entire process, you must understand how to select a suitable pump for your inground pool. Note that you have to consider certain aspects such as your pool volume, flow rate, and pipe size when choosing the right pool pump.

Should I Install My Inground Pool Pump?

A lot of the pool equipment manufacturing companies require you to hire a professional during installation. Understand that they will need ‘proof of professional installation’ when registering for the product warranty.

This is because it can be rather risky to install your pool equipment, especially when you don’t have any electrical or plumbing skills. Improper or poor installation might damage the pool pump and filter within a short period.

What this means is that you should always hire a professional when installing any pool equipment. Understand that pool equipment is rather expensive and will probably cost you a fortune. It can be rather frustrating when you damage your equipment on the first day of installation.

Most pool owners are usually left in a dilemma because they won’t qualify for the warranty unless they hire an industry professional. However, if you need to work on your project by yourself, then you will have to forfeit the warranty on the product.

Choosing the Right Pool Pump

The first step is picking out the right pump for your inground pool. The good news is that there have been several upgrades in recent years when it comes to pool pumps. You can get a variable speed pump that is much more energy-efficient than the old single-speed variations.

Note that getting the new pool pumps also makes it easier to find replacement parts in case of any problems in the future. Most of the single-speed pumps are slowly being phased out which will make it almost impossible to find replacement parts in the future.

Before you can determine the perfect pump for your inground pool, you have to consider several key aspects. What is the size of your suction line pipes? What is your pool volume in gallons? What kind of filter are you planning to install?

It would also help if you considered whether you have a 120-volt or a 240volt electrical outlet for your new pool pump. Once you have all this information figured out, you can find the appropriate pool pump for your filtration system.

Understand that your pool pump needs to be able to filter your entire pool three times in 24 hours. Note that this is the industry standard for all residential pool filtration systems. For example, your pump needs to filter at least 30,000 gallons within 24 hours if you have a 10,000-gallon pool.

Choosing a Suitable Pool Filter

Now, understand that every pool filter includes a maximum flow rate. Understand that the filter will not work appropriately when you exceed the flow rate. You might also end up damaging the pool filter when you overwork the system.

Understand that sand filters are more limiting when compared to DE and cartridge filters. Start by looking at the maximum designed flow rate of the filter before making a purchase. Most experts will tell you to go for a bigger filter than what your pump needs. Understand that a small filter will limit the capabilities of your pool pump.

Pool Pump and Filter installation

Installing a new pool pump is not an easy task. Most people will spend the entire day working on the installation only to realize that they have no running pump by the end of the day. Understand that the plumbing system is never straightforward.

In most cases, you will have to deal with PVC but you can always find yourself looking at a poly pipe, flexible PVC, copper pipe, ABS pipe, and so much more. Start by figuring out the type of plumbing system that you are dealing with during the installation process. If you cannot figure out the kind of plumbing system in your pool, you will have a hard time installing the pool pump.

Understand that each inground pool pump has a unique orientation making the process even more challenging. However, start by ensuring that there is a straight section of pipe going straight into the pump’s suction side. If you can have a straight and unobstructed run, then the flow dynamics of your pump will be greatly improved.

If you have an existing pool system, then you will not enjoy the dynamics of design changes. All you need to do is place the pump where it needs to go and install it without any leaks. However, always ensure that you read the user manual to get a clear picture of where everything goes within the system.

Choosing the Right Pool Pump

Inground Pool Pump Thread Sealant

Use 100% silicone thread sealant when working with an inground pool pump. Ensure that the sealant is left to sit overnight before you can run the system. Apply your thread sealant to the male adapter and thread it into the female adapter as far as you can go by hand. Do not use a pipe wrench during this process because you might end up causing a lot of damage.

Pump Intake Height

What happens when you have a horizontal pipe going into the pump’s suction side? Well, all you need to do is change the pump intake height. However, ensure you shop for a pool pump with the same intake height as your pool plumbing to avoid this step. Note that changing the pump’s intake height can be a rather difficult task that is labor-intensive. (source)

Pipe Connections

Always use a 40 rigid PVC pipe when installing an inground pool pump. Unless you want to match an existing pipe material, always go for the standard option. However, ensure that all pipe connections are 100% leak-free. Do not take any shortcuts when installing the pipes to avoid causing damages to your pool system.

Pool Filter

The pool filter is always installed right after installing the new pool pump. Ensure that you read the manual on how to effectively install your new filter. Note that each filter will have different installation instructions.

However, every filter includes two basic plumbing conditions. The influent line brings water into the filter while the effluent line provides an outlet for the filtered water.

Ensure you install a gate valve on both the effluent and influent lines of your new filter. Note that the plumbing lines need to be connected to the filter’s multiport valve. Ensure that the connection is done appropriately using thread sealant and PVC cement where necessary. Click here to read more about cartridge pool filter.
