Filter System

Filter systems are designed to remove debris suspended in the water by pushing it through a filtering media and trapping the material before the water returns to the pool.

There are three basic kinds of filter systems for swimming pools: cartridge, sand, and diatomaceous earth (DE )

  • A cartridge filter is much like a coffee filter. Made of corrugated paper or polyester cloth, a cartridge filter can be removed and cleaned with a hose. Cartridge filters must be replaced when they become worn or damaged. Expect cartridges to be replaced every other year on a seasonal commercial pool and every year for a pool in operation all 12 months. It’s a good practice to have a backup set of cartridges available for when it’s time to clean the operating set.

  • Sand filters trap the debris inside one or more filter tanks as water works its way through the sand contained in the vessel. Gravity pulls the water down through the sand, and fine debris is trapped in the sand bed. The filtered water then exits the tank and travels back to the pool through the return inlets. Backwashing is a process that must be performed 1-2 times weekly in most cases to clear the debris from the tanks. Sand filters should have their sand replaced every 4-5 years to maintain function.

  • DE filters depend on the usage of diatomaceous earth (DE), which is made of ground fossilized remains of sea organisms called diatoms. In this system, filter grids are covered with a fabric septum and then coated with DE. The water flows through the DE and through the septum on the grids, where debris is trapped. DE is particularly good at trapping very fine debris.

Sanitation

Pool water sanitation through chemical treatment works alongside effective filtration to maintain a healthy, safe, and code compliant swimming pool environment. Our technicians understand the advantages and challenges of every option in pool treatment from the most basic chlorine feeders to sophisticated automated systems with salt chlorine generation.

CHEMICAL FEEDERS

Chemical feeders inject sanitizers or pH adjusting chemicals into the water through the filter system;s return line. There are several types of chemical feeders; they can be operated manually or through an automated system.

Peristaltic Pumps

feed liquid chemicals from a storage vat into the pool return line. 

Erosion Feeders

dissolve chemicals in a tablet form such as trichlor or bromine and introduce them into the pool water over an extended period. These feeders need to be refilled as the tablets are depleted. 

Salt Chlorine Generators

dissolve chemicals in a tablet form such as trichlor or bromine and introduce them into the pool water over an extended period. These feeders need to be refilled as the tablets are depleted. 

Ozonators

do not provide a chemical residual that the health department can monitor so they can’t be used on their own in commercial pools. Ozone is generated and injected in the water where it destroys bacteria before it reverts back to oxygen form. 

Pumps and Motors

A pool pump is driven by the motor, drawing water from the skimmer and main drains in the pool and then pushing it through the filter where debris can be removed. It may also push water through a heater to warm the water. The water is then pushed back into the pool through return lines. Pumps and motors must be sized properly to assure compliance with the health authority and keep the pool looking its best. Our capable technicians perform the necessary calculations and review pump curves to make the best recommendations and assure proper function.

Pumps can be paired with a motor that is single speed, two speed, or variable speed.

Single-speed motors

are the least energy-efficient because the pump is always running at the same speed and it cannot be adjusted for a facility’s specific needs.

Two-speed motors

are more energy-efficient and offer a high and low-speed option.

Variable-speed motors

offer the greatest energy efficiency and allow the pump to be regulated based on a facility’s specific demands and schedules.

The motor required is determined by the pool volume and turnover rate needed to meet or exceed code. It’s important to match the horsepower of the pump’s motor to the pump type and flow rate. If a pump’s motor is too powerful, it can cause problems with filtration and result in damage to the filters and heating systems. The filter system must be designed to accommodate the flow that the pump and motor are generating.

Leak Detection and Repair

A pool can develop a leak for many reasons such as winter damage, equipment failure, facility age and type of construction. A poorly maintained pool can lose thousands of gallons per day and hundreds of thousands throughout the pool season. Leaks in a swimming pool should never be ignored because they not only waste water and chemicals, they make the pool itself more prone to movement and structural damage. Our leak detection and repair experts consult with pool owners to identify the source of a leak and provide the most effective solutions to preserve the integrity of your pool for many years to come.

Effective leak detection requires a well-ordered process.

  • Consultation A discussion with the pool operator or pool owner is essential in getting the basic information needed about the pool’s history and details about how much water is being lost daily. This background information provides our leak detection experts with clues on where to focus their attention.

  • Inspection A visual inspection provides more background information about the pool in its current state. This inspection will also help to fill in any details or gaps from the initial consultation.

  • Observation Several non-invasive tests can be performed in cooperation with the pool owner or facility manager. Static Tests, Bucket Tests, and Dye tests help identify leak sources not related to underground plumbing.

  • Pressure Testing The testing of underground plumbing requires a pressure test. Individual pool lines are put under pressure and observed for a specific time. Loss or maintenance of pressure is noted as this may indicate which line or lines are leaking. Listening devices, Cameras and Helium testing devices may also be employed to identify leak locations.

  • Repair After testing is completed, our experts provide a detailed report and make recommendations for the most effective repair. If the solution requires extensive work, short term approaches may allow a client to get through the season so they can do the major repair after the pool season. Leak repair is best executed immediately after the pool season so that there is plenty of time to address any unforeseeable challenges.

Pool Heaters

Extend your pool season with the installation of a pool heater or heat pump. Natural gas, propane, heat pumps, electric, and even solar heating systems are all available to keep your pool temperature comfortable. There are code, safety, and efficiency considerations when selecting and installing a pool heater. A trained professional will help you make the right choice and provide a smooth installation process.

Gas Heaters

A gas heater is the most effective way to boost your pool temperature at the start and end of the pool season. Natural gas or propane is burned in a combustion chamber. Propane requires a fuel tank, which must be refilled when empty. Gas heaters typically cost a great deal less than heat-pump filters on installation, but they are less efficient, which may result in greater utility costs over time.

Heat Pumps

A heat pump doesn’t heat the water as quickly as a gas heater, but works to sustain comfortable bathing over a long time. This electrical appliance uses a condenser system to extract heat from circulating air and transfers it to the pool. A heat pump should work effectively as long as air temperatures remain above 50 degrees Fahrenheit. They are more expensive to install initially but operate at a lower utility cost.

Solar-powered heaters

convert sunlight into energy. The pool’s pump circulates water through the heating elements and a timer is set so that the heater operates only during daylight hours. Because the heater needs sunlight to run, cloudy or stormy weather can reduce its effectiveness.

Pool Covers

A properly installed safety cover acts as an important safety feature by preventing children and animals from accidentally entering the water if they access the pool area outside of the operating season. Pool covers can also keep debris like falling leaves from entering the pool, which is particularly important during the fall and winter months to prevent staining. Pool covers come in standard sizes but are most often custom made for commercial clients. Measuring for a pool cover and making notes on any features such as raised walls, waterfalls, slides are an important aspect of the job. Our technicians have been trained in all facets of pool cover installation and work closely with the manufacturer to assure excellent fit and function.

  • Mesh Safety Covers can be ordered in several grades and colors. The mesh material allows rainwater to pass through but blocks leaves and other materials from entering the water. These covers are anchored to the pool deck and help make an off-season pool area maintain a tidy appearance.

  • Solid Pool Covers are appropriate for smaller pools blocking water and sunlight from penetrating their structure. They require more off-season maintenance to keep water from accumulating on top of the cover and typically use a small electric pump to remove surface water. These covers are very effective in arresting the growth of algae in the off-season when a pool is not circulating.

  • Automatic Pool Covers are typically installed as part of a pool’s initial construction. Retrofitting a pool for an automatic cover is possible but not always cost-effective. An automatic pool cover runs on a track system incorporated into the pool wall and can be opened and closed at the push of a button.
