Sand filters are great at filtering out particles from water. They are also known for their ability to remove bacteria and other contaminants.

The problem is that they don’t last forever. Sand filters eventually become clogged and require cleaning or replacement.

It may seem like a difficult job, but setting up your pool with a sand filter system (see also ‘How Much Sand To Use With Your Sand Filter System’) is relatively straightforward.

The first step in installing a sand filter is to find out what size of sand you need for the project.

Sand can be purchased from most hardware stores or online at places such as The next step is to determine how much sand you will need.

Your local home improvement store can help you figure out the correct amount. Once you’ve determined the quantity, you’ll need to measure the area where you plan to place the filter. 

Once the sand has been placed, you’ll need to install the filter itself. This process usually involves connecting the various parts together.

After everything has been connected, you’ll need to test the filter by running some water through it.

If everything works properly, then you’re ready to enjoy cleaner, clearer pool water. 

There are 3 different types of hoses that you may have to connect to your sand filter system.  These three types are detailed below. 

Table of Contents

Hose #1

The first hose connects a pool’s through-wall filter to the pool’s pump. You should be able to connect the hose to a fitting on the skimmer.

Slide the clamps onto both ends of the hose to secure them. Attach one end of a hose to the skimmer fitting and tighten the clamp. Push it on tightly. 

Always use two clamps to make sure that you get a good seal.

The other end of the hose will connect similarly to the one that connects to the fitting at the back of the strainer housing.

The strainer housing is located on the front of the pump and has a clear lid and a mesh basket inside it.

Hose #2

The second hose connects to the pump port located at the back of the strainer housing.

It’s usually a shorter and heavier duty hose than the others.

Slide the clamps on the both ends of the water hose, then install the water hose onto this fitting. Use a screwdriver to tighten the clamps.

Hose #3

The last hose connects to the port labeled “return“ on the sand filter valve and goes to the water returning jet of the pool.

Like the previous steps, you will be installing the hoses using clamps.

Connecting Hoses To Your Sand Filter

How To Connect Hoses To Your Sand Filter

Sand filters can be a bit of an ordeal when it comes to connecting the various parts together.

There are several different ways you can do this, but we will focus on one method in particular: using a hose adapter.

A hose adapter is basically a piece of plastic with holes cut into it. It allows you to attach two pieces of tubing together by threading them through the holes. 

This makes it easy to connect two things together without having to use any tools.

You simply push the ends of the tubes into the holes until they meet up.

Once the two tubes are connected, you can then attach whatever you want to the end of the tube.

There are many different types of hose adapters available. We have found the most popular ones to be the following:

Hose Adapter 1 – This is a simple type of hose adapter that has a single hole drilled into it. The hole is large enough to allow both ends of the tubes to fit inside.

Hose Adapter 2 – This is another common type of hose adapter. Unlike the first type, there are multiple holes drilled into the adapter. This allows you to connect more than just two tubes together.

Hose Adapter 3 – This is yet another type of hose adapter. It is similar to the second type, except that instead of drilling holes, it uses tabs to hold the tubes in place. These tabs make it easier to disconnect the tubes if you need to.

Connecting The Hose To The Sand Filter: A Guide

The next step is to connect the hose to the sand filter. To do this, you will need to find the right fitting.

The fitting should go onto the end of the hose where the sand filter is attached.

If you are unsure which fitting goes on the hose, take a look at our guide on how to choose a sand filter.

Once you know what fitting goes on the hose, you can start attaching everything together.

First, you will need to put some tape around the outside of the hose so that it doesn’t split. Next, you will need to slide the fitting over the end of the hose. 

Make sure that the fitting is tight against the hose before you tighten down the screw.

Then, you will need to turn the screw clockwise to secure the fitting.

When you finish tightening down the screw, you will need to add some more tape to keep the screw from loosening again.

Once you have finished securing the fitting, you can now attach the sand filter to the fitting.

Use a wrench or pliers to unscrew the nut on the back of the sand filter. Slide the sand filter off of the fitting and onto the hose.

Turn the nut counterclockwise to secure the sand filter to the end of the hose and then tighten down the nut.

Now that you know how to connect hoses to sand filters, let’s take a look at some tips on how to properly install these devices.

First off, you should always read the instructions included with the equipment before attempting to use it.

If you follow the directions carefully, you won’t have any problems.

However, if you skip over important steps, you could damage the device or even cause harm to yourself.

The next thing to keep in mind is the sand filters. If you follow the directions carefully, you shouldn’t encounter any problems.

When installing the sand filter, you should start by attaching the bottom plate to the base of the tank.

Next, you should screw the top plate onto the bottom plate. Finally, you should attach the intake pipe to the top plate.

Now that you have everything attached correctly, you can turn the valve on the side of the tank so that it starts drawing water into the system.

If you ever notice that the water isn’t flowing as expected, you may have damaged something during installation.

In that case, you should stop what you are doing immediately and contact a professional.

Cleaning Your Sand Filter

How To Connect Hoses To Your Sand Filter

One of the most common questions we get asked is how often you should clean your sand filter.

Unfortunately, there isn’t an exact answer for this question.

You should run a backwash through your sand filter every 4 weeks or so, but a full clean should be done approximately once a year, unless you’re experiencing problems with your filter.

To clean your sand filter, you should first remove all of the dirt that has built up inside of it.

This means removing the sand filter from its base and cleaning the entire unit.

Once you have cleaned the sand filter, you can replace it in its base. To do this, simply lift the sand filter up and place it back in its base.

You should also make sure that you regularly check the water level of your pool, especially when using a sand filter.

The amount of water that you have in your pool will determine whether or not you need to clean your sand filter.

For example, if you only have one foot of water in your pool, you probably don’t need to clean your sand filter very often.

On the other hand, if the water level in your pool is unusually low and your sand filter doesn’t seem to be working well, you should consider cleaning it.

How To Clean The Sand Filter: A Step-By-Step Guide

Before starting to clean your sand filter, make sure that you have removed all of the debris that has built up inside.

It’s best to remove the sand filter from its stand and thoroughly wash it. After washing it, you should dry it completely and then reinstall it.

After you have installed the sand filter, you’ll want to fill the reservoir with water until it reaches the maximum recommended capacity.

Then, you should turn on the pump and allow the water to flow through the sand filter.

As soon as you see some bubbles coming out of the sand filter, you know that it is time to perform a backwash.

The first step in performing a backwash is to open the access door located at the front of the sand filter.

Next, you should take off the cover plate located near the top of the sand filter.

Then, you should carefully unscrew the two screws holding the sand filter together.

After you’ve loosened these screws, you should pull the sand filter away from the wall.

Next, you should use a garden hose to spray the sand filter with water.

Make sure that you keep the nozzle pointed directly into the center of the sand filter.

When you finish spraying the sand filter, you should let the water drain out of the sand filter before replacing the cover plate.

Once you have replaced the cover plate, you should wait 10 minutes before turning the pump back on again.

If you are still having trouble getting rid of the bubbles, you may need to repeat the process described above.

Once you have performed a proper backwash, you should now be ready to install the sand filter back in its base.

First, you should loosen the four screws that hold the sand filter in place. Then, you should gently slide the sand filter out of its base.

Finally, you should carefully lower the sand filter back down into its base.

How To Install A Sand Filter For Your Pool

How To Connect Hoses To Your Sand Filter

To properly install a sand filter, you should follow these steps:

Choosing The Type Of Pool Filter

First, you should decide which type of pool filter you would like to purchase.

There are three different types of filters available today: cartridge filters, mechanical filters, and sand filters.

Each of these filters has its own advantages and disadvantages. You should choose the type of filter based on how much maintenance you expect to do.

If you plan to do little more than occasionally change the filter bags, you should look at a cartridge filter.

These filters work by trapping particles of dirt and debris within their internal chambers.

They can last longer than other types of filters but they require regular cleaning.

If you expect to clean the filter regularly, you should consider purchasing a mechanical or sand filter.

Mechanical filters use a series of screens to trap particles of dirt and debris. The screens are usually made of stainless steel mesh.

Sand filters are similar to mechanical filters except that they also contain a layer of sand.

This layer of sand traps particles of dirt and debris so that they cannot escape.

Sand Filters Vs. Mechanical Filters

Sand filters are generally less expensive than mechanical filters.

However, they are not as durable because they don’t have any moving parts.

On the other hand, mechanical filters are very durable, and they tend to cost more than sand filters.

When choosing between a sand filter and a mechanical filter, it’s important to remember that both types of filters will remove particles of dirt and debris from your swimming pool.

What makes one type better than another depends on what kind of maintenance you want to perform.

Pick A Location For The Pool Filter

Next, you should pick a location where you would like to put the pool filter. It is best if this location is away from the sides of the pool.

This way, when you turn off the power supply to the filter, there won’t be any danger of electrocution.

You should also make sure that the pool filter doesn’t interfere with the flow of water through the pool.

For example, if you have a waterfall feature in your pool, you shouldn’t put the pool filter near the waterfall.

Instead, you should put the pool filter somewhere else.

You should also avoid placing the pool filter too close to an underwater light fixture.

If the filter gets too hot, it could melt the plastic housing around the light fixture.

Turn Off the Pool Pump

Once you’ve picked a good location for the pool filter, you should then turn off the pump that circulates the water through the pool.

By turning off the pump, you’ll prevent any accidental damage that might occur during the installation process.

Assemble The Pool Filter

The next step is to assemble the pool filter. To do this, you should first attach the hose to the intake valve.

Then, you should attach the intake hose to the filter itself. Finally, you should attach the outlet hose to the filter.

After all of these steps are complete, you’re ready to start preparing the piping connections.

Prepare The Piping Connections

Before attaching the piping connections, you should thoroughly wash them.

You should also dry them completely before connecting them together.

To prepare the piping connections, you’ll need two pipe connectors. One connector should go into each end of the intake hose.

After you’ve attached the pipes together, you should tighten up the connection using a wrench.

Attach The Hose To The Intake Valve

To attach the hose to the pool filter, you’ll first need to open up the intake valve.

Then you should insert the end of the hose into the opening. Next, you should twist the hose until it tightens against the valve.

If you’re having trouble getting the hose to fit properly, try tightening up the hose by twisting it clockwise.

This will help the hose get snugly against the valve.

Attach The Hoses To The Outlet Valves

Now that you’ve connected the intake hose to the intake valve, you can repeat the same procedure with the outlet hose.

First, you should open up the outlet valves. Then, you should insert the end portion of the hose into the openings.

Next, you should rotate the hose until it is tight against the valves.

When you’re done, you’re ready to test out the pool filter.

Before doing so, however, you should take note of how much water comes out of the pool filter.

The amount of water coming out of the pool filter indicates whether or not the pool filter is working correctly.

Test The Pool Filter

To check on the performance of the pool filter, you must first shut down the pump.

Then, you should remove the cover and look at the level of water inside the filter.

If the water level is low, then the pool filter isn’t filtering as well as it should be.

However, if the water level is high, then the pool filter is working fine.

Record The Initial Internal Pressure

You should record the initial internal pressure of the pool filter after you’ve installed it in the pool.

To do this, simply measure the pressure inside the filter. When you’re finished measuring the pressure, you should write down the reading on a piece of paper.

Next, you should wait about 30 minutes before taking another measurement. During this time, the filter should continue to work.

As soon as you take the second measurement, you should compare the results with the previous one.

If the readings differ significantly, then there’s something wrong with the pool filter.

Tips For Installing A Sand Pool Filter

Buy the amount of sand or appropriate sand substitute recommended by the sand filter’s manufacturer.

Use a water-soluble, non-toxic disinfectant such as household bleach to clean the inside of your sand filters.

Store the filters in an area that is not exposed to sunlight and away from children.

Remove the filter when it has been used for several months.

Remove the filter from the pool when you are going to use it again.

Check the filter regularly to ensure that it continues to function properly.

Before filling the filter’s reservoir with sand, add some water to the halfway point in order to protect its lateral assemblies.

Backwash the filter before running it for the first time. Make sure the wastewater line is ready to release water in your chosen location before starting.

Turn the pool pump on and adjust the sand filter to the correct setting after performing the backwash.

After about five to seven years of use, you should empty the tank and replace the sand inside.

The sand is made up of tiny particles that can get into your skin and cause irritation or infection.

If you don’t clean it out regularly, bacteria will build up in the tank and make it smell bad.

You may also notice that the sand becomes clogged over time. This could lead to reduced filtration efficiency.

In addition, the sand could become too heavy for the filter to move through. If this happens, you’ll need to change the sand.


Sand filters are very effective at removing impurities from your pool water. They are easy to install and maintain.

You should only buy a quality sand filter, though. Otherwise, you might end up spending more money than necessary.

A sand filter is a great way to keep your swimming pool clean. It removes debris, algae, and harmful bacteria from your pool water.

The best type of sand filter uses granulated activated carbon. The filter is designed to hold large amounts of sand.

However, if you want to remove smaller contaminants, you can use a fine-grained sand filter instead.

Sand filters are a good choice for keeping your pool clean. They are inexpensive and relatively easy to install. 

We hope that our guide has helped you choose the right sand filter for your needs, and you’ve managed to successfully install your sand filter and connect the hoses without too much trouble.
