About Pool Filters

Maintaining your sand pool filter is a crucial part of your pools maintenance.  One of the things you must consider doing every 3-4 years is replacing the sand in your filter.

Why do you need to change the sand, you may ask?

Your filter’s job is to keep your pool water crystal clear.  To do this, water is pumped through the filter, where debris, dust, skin, hair, sunscreen particles and oil are caught by the sand, allowing clean, clear water to pass back into the pool.  Over time, the sand becomes clogged with all this organic matter.  As a result, the filter is not able to work properly.  Changing the sand allows the filter to continue being efficient and effective in keeping your pool clean.

Steps to cleaning out the sand in your filter:

1. Remove the old sand – this can either be removed with a vacuum, or alternatively by scooping out the sand with your hand or a small shovel. Because the sand is full of dirt and bacteria, it is best to wear rubber gloves when cleaning it.

2. Place some tape over the sand pipe. This is the open pipe in the middle of the tank where your sand is held.  Hold the sand pipe in the centre of the tank for the next two steps (if you don’t and the pipe moves, it is near on impossible to adjust once the sand has been replaced).

3. Add water to the filter tank, then put the new sand in. This helps to protect your filter from the impact from the sand falling into the filter.  The best sand to use is #20 silica sand as it is specifically recommended for filtering, and won’t damage your filter.  It is available from most pool supply stores nationwide

It is important to find out how much sand your model of filter requires, as using too little or too much will affect the ability of the filter to work properly, and could even irreparably damage it.

4. Replace the filter head and tighten. Finger tightening is ample, as overtightening can cause the body of the filter to crack.

5. Complete a backwash through the filter. To complete this, make sure the pool is overfull, the backwash the filter for 3-5 minutes, followed by a 1 minute rinse cycle.

These easy steps will return your sand filter back to its original, clean, state.

One of the most important aspects of pool maintenance is to make sure your pool filter is changed on time.  Pool filters are an important part of keeping your pool clean, as well as ensuring the water pressure remains within the correct range.

How do you know when your pool filter needs to be changed, though?

All types of pool filters have a recommended life.  They are:

Sand:               7-10 years

Cartridge:        2-5 years

Grid:                7-10 years

Sometimes filters need to be changed earlier than this though, due to a number of things.  If you don’t use a pool cover, more debris and dust will enter the pool and thus need to be filtered out.  The more dust and debris, the quicker your filter will clog and need to be replaced.

So, you may ask, how will I know if my pool filter needs to be replaced?  If, after checking your pool chemical levels, your pool is cloudy, or it has a lot of debris always present, you have low pressure coming out of the inlet valves, or the filter is clogging, this will point to the need to replace your filter.

Instead of a swimming pool in your backyard, does it look like you have a murky swamp?  Does it appear cloudy with lots of contaminants in it?

Have you checked the pools alkalinity, chlorine levels and pH levels finding they are within range?

If yes, then it means it is time to replace your filter!

Filters work by dirty water from the pool being sucked into the filter, then dragged through the filtering substrate, which in turn catches all the dirt and dust.  The clean water is then pumped back into the pool.

When a filter has been used for a significant amount of time, the filter substrate starts to become blocked with contaminants, and as the water passes through, it pushes the older contaminants, blocking its path, back into the pool.  As a result the water gets dirtier and dirtier as more dust and debris land in the pool and aren’t removed.  This results in your water becoming stagnant, giving it the cloudy look.

As soon as you see your pool becoming murky, and the chemical balance is correct, you should replace your filter or filter cartridge (depending on your model).

No need to fret though!  Even if your pool could be currently housing a scary swamp monster, it can be saved, by replacing the filter as soon as you can!

Most people know that a pool has a filter, but you may ask, do I actually need one? The short answer is yes!

Pool filters are necessary to keep your pool healthy and clean. It is an essential component that keeps the water clean by filtering out all the dirt, debris, clothing fibres and organic material that makes its way into your swimming pool water.  Without a filter, your pool will quickly grow algae and bacteria, as well as turn an unsightly colour.
