Filter out the unseen to keep water clean.

Cleaner, clearer, healthier pool water starts with the right filtration system reducing the need for excessive maintenance, saving on chemicals.

A beautiful, clear pool should be easy to enjoy—not a constant source of stress. If your water is cloudy, algae keeps returning, or chemical levels are always off, it’s a sign that your pool system isn’t working efficiently.

Is Your
Pool Water
Water Cloudy or
Difficult to Maintain?
It’s Time,
To Call The Experts.

Cloudy or murky water – even after regular cleaning, your pool lacks that crystal-clear sparkle due to poor filtration or imbalanced chemistry
Frequent algae growth – persistent green or black algae indicate circulation or sanitation problems that need expert attention
Poor water circulation – inadequate flow prevents chemicals from evenly distributing, causing hot spots and stagnation
Excess chemical usage – constantly adding chlorine or other chemicals without lasting results increases costs and can irritate skin and eyes
Weak or failing filter system – outdated or underperforming filters can’t keep up with debris, reducing water clarity and system efficiency

These are warning signs that your pool needs professional diagnostics, maintenance, or upgrades to restore clean, healthy water.

FILTER TYPES

Which pool filter is best for you?

Choosing the right pool filter starts with understanding the different types and how they work. Let our experts guide you through the options.

Sand Filter

A budget-friendly option that requires minimal maintenance, sand filters are ideal for in-ground or above-ground pools.

How a Sand Filter Works

As pool water is pumped through the filtration system, it's pushed through a filter tank filled with sand where contaminants and debris are caught on the spiky edges of each sand particle. Standard sand used in sand pool filters are capable of filtering contaminants that measure 20 microns and larger. As water continuously flows through the filter, the contaminants trapped between the sand begin to build up — eventually restricting the flow of water, increasing internal pressure and reducing the filter's efficiency. However, with proper maintenance, a sand filter will continue to keep your pool clear and clean.

Sand Filter Maintenance

While you only need to replace the sand in your pool filter every 5 to 7 years, occasionally you will need to backwash the filter to clear out all the built-up debris. This is an easy cleaning method that simply reverses the flow of water back through the sand filter, flushing debris out to waste. Knowing when to backwash a sand filter is easy. A pressure gauge on the sand filter alerts you when internal pressure increases and it's time to backwash the filter.

Sand Filter Advantages & Disadvantages

Advantages: Low upfront cost, easy maintenance, sand lasts 5 to 7 years before needing to be changed, filtration efficiency can be boosted with additives or alternative media Disadvantages: 20-micron filtration is the least effective of the three types and backwashing is viewed by some as not environmentally friendly due to water waste.

Cartridge Filter

Cartridge filters are slightly more expensive than sand filters, and require a bit more maintenance, but can be more effective and energy efficient if you have a larger pool.

How a Cartridge Filter Works

Rather than using sand as a filtering agent, cartridge filters contain a pleated polyester filter. Just as your pool water is pumped through a sand filter, water flows into the cartridge filter tank and through the pleats where debris as small as 10 microns is captured, leaving only clean water to return to your pool.

Cartridge Filter Maintenance

Over time, as the filter collects debris, you'll need to remove the pleated cartridge from within the tank to clean it. Unlike a sand filter that can be backwashed, to clean a cartridge pool filter you simply need to remove the cartridge and spray it down with a hose until the water runs clear. While this requires slightly more work than a sand pool filter, it wastes less water than backwashing.

Cartridge Filter Advantages & Disadvantages

Advantages: Filters contaminants as small as 10 microns, no backwashing; less water waste, performs well at low speeds, such as with variable-speed pool pumps, cartridge inserts are inexpensive to replace, mid-cost filter Disadvantages: Requires slightly more manual work than sand pool filters, cartridge needs to be replaced every 2 to 3 years, deep cleaning required 1 to 2 times per year.

Diatomaceous Earth Filter

Diatomaceous earth (DE) filters are capable of filtering particles as small as 2 to 3 microns, providing the cleanest, clearest water of all three types of pool filters. However, DE filters are more expensive and require the most maintenance of the three pool filter options.

How a Diatomaceous Earth Filter Works

First and foremost, what is diatomaceous earth? It's a white powdery substance made from the crushed fossils of aquatic organisms called diatoms, often referred to as "water polishers" because they leave pool water sparkling clean. DE pool filter tanks contain several grids coated with diatomaceous earth. The diatoms act just like a sponge — water can pass through, but microscopic impurities like dirt, algae, and some forms of bacteria can't.

Diatomaceous Earth Filter Maintenance

Diatomaceous Earth Filter Advantages & Disadvantages

Advantages: Highest degree of water clarity, filters contaminants as small as 2 microns, DE powder can be added through the pool skimmer, no caustic chemicals are required for cleaning Disadvantages: Highest cost filter, requires more maintenance, grid needs to be replaced every 2 to 3 years, backwashing wastes water and may be restricted by location (check with your pool pro to find out), DE powder can be harmful if inhaled (Wear a mask!)

VALVE TYPES

Which valve is right for your needs?

Selecting the right pool or spa valve starts with understanding the different types and how they work. Let our experts guide you through the options.

Diverter Valve

The most requested swimming pool valve on the market. Diverter pool valves divert water and are available with two or three ports.

A 2-port valve essentially acts as a 1-way-in / 1-way-out valve, allowing for water flow to be shut off completely or to restrict the flow of water for a lower flow rate.

A 3-port valve provides more flexibility with one in-port and two out-ports that regulate the direction water flows.

Check Valve

A pool check valve is a type of pool valve that provides for one-way water flow, or more importantly, to prevent the flow of water in the opposite direction.

Some pool check valves also allow you to monitor the flow of water through a clear lid to ensure proper pool check valve operation.

Pool check valves are most commonly used for the following reasons:

For pool pads installed on higher ground or several feet above the pool water level to prevent water from draining back into the pool when the pump is not running.
To prevent backflow of water from a chlorinator into a heater or filter. This water contains a high concentration of chlorine and can potentially damage the pool heater.
To prevent backflow of water into a spa air blower which will damage the blower's motor.
To prevent cycling of water in a loop, e.g. solar heater systems.

Ball Valve

Similar to a two-way diverter valve, a ball valve is used to regulate the flow of pool water in one direction and is best utilized to shut off the flow of water completely.

Select the Perfect Valve for your Needs.

Selecting the right pool or spa valve starts with understanding the different types and how they work. Let our experts guide you through the options.
