HOW DOES A SWIMMING POOL
FILTRATION SYSTEM WORK?

As Swimming Pool Leak Detection Experts we aim to write about swimming pools, filtration systems and how pool leak detection works in laymans terms, helping you to carry out some DIY pool leak tests and gain a deeper understanding of your swimming pool system.

All swimming pools are constructed and operated on the same principle.

In other words, regardless of the shape, size, and additional features; the functioning of all pools is basically similar. They all use a combination of chemical treatment and filtration to keep the water clean and healthy at all times.

In this post, we’ll be looking at the filtration system and how it works. Usually, the water filter is used to keep algae and other hazardous contaminants at bay.

Pump

The pump is the most important part of a pool filtration system. Its electric motor spins an impeller to move water from drains and skimmers through its wet end section to the filter.

The wet end section includes the shaft seal, strainer lid, diffuser, strainer bucket, impeller, and strainer ring.

Filter

Dirty water goes through the filter's inlet pipe to a distribution head in the tank. Different filter types (cartridge, sand, diatomaceous earth) trap debris.

Pressure gauges indicate blockage, and regular backwashing or cleaning is necessary. Filters remove visible debris, invisible contaminants (micro-organisms, pathogens, insects, food particles, saliva, sweat, urine, fecal matter), and hinder algae/bacteria growth.

Here Are The Major TypesOf Pool Filters

Cartridge filters

Cartridge filters are easy to use for above-ground pools, filtering by holding dirt particles. They can be cleaned with a hose but need annual replacement.

Diatomaceous Earth (DE) filters

DE filters are highlighted for removing tiny dirt particles (as small as three microns). The DE system involves manual cleaning and backwashing, requiring DE powder to be added in each session. The powder, made of microscopic diatom skeletons, absorbs debris like a sponge.

Sand filters

Dirt water passes through sand, trapping particles, and clean water returns to the pool. Dirty sand requires backwashing (running the filter in reverse). Sand can be recycled for at least five years, and glass media is mentioned as a better alternative.

Parts of a sand filter:

  • Corrosion-proof hollow tank
  • Specially graded sand media
  • Integral top diffuser for even water distribution
  • Slotted lateral pipes to balance sand flow
  • Laterals to hold back sand while allowing water to pass
  • Corrosion-proof bases
  • Drain plug
  • Multiport valve at the top of the tank with a clamp and o-ring

Importance of BalancingThe Pool Water

The pool filtration system plays a crucial role in maintaining cleanliness and health. A healthy chemical balance benefits swimmers, the pool, and its equipment.

An untreated or poorly treated pool can harbor pathogens. Incorrect chemical balance can damage pool parts (like filters) and cause water to become grey, cloudy, and irritating to eyes and skin.

PoolLeakages

Pool leaks are common both inside and outside the pool. When looking for a leak, check the entire filter system (heater, filter, pump, chlorinator).

Leaks can occur in in-ground pools due to cracked underground piping. It's important to distinguish water loss from leakages versus evaporation.

Contact a professional leak detection company for non-invasive leak pinpointing due to their specialized equipment and skills.

Lookout for these Signs of pool leakage

  • Extraordinary discoloration of water or algae growth
  • Abnormal consumption of water
  • Varying chemical consumption
  • Failing or loose tiles
  • Cracking of the swimming pool cement deck
  • The pool settling into the ground
  • Water corrosion around the pipes or at the pump
  • Soggy soil at the underground plumbing lines

Why You Should NEVERIgnore A Pool Leakage

Pool leakages are both an inconvenience and a potential hazard. Water escaping from the pool system can easily start accumulating in areas that it shouldn’t.

For instance, chlorinated water can spill off and damage metal components around the pool structure such as rebar covering, shells of the concrete swimming pool and galvanized steel of a vinyl liner pool walls.

Besides, the leaking water can carve through the ground of the pool if left unattended. Over an extended period, the water washes away cement strips from the concrete, leaving only gravel and sand behind. This damages the pool basement.

Pool leaks are both an inconvenience and a potential hazard. The earlier you get a leaking pool fixed, the better.
