Common Pool Issues: How to Fix and Avoid Them (and When to Call a Professional)

Without regular maintenance, even a high-quality swimming pool can experience issues with its water, equipment, and surfaces. Outdoor pools in Saudi Arabia contend with intense heat, fine dust particles in the air, sand blown by the wind, swift evaporation, and significant usage for the majority of the year. These circumstances speed up chemical depletion, heighten the need for filtration, and place additional stress on pool pumps, heaters, and surfaces.

Some of the common pool problems have straightforward fixes, while others require professional diagnosis and repair. This piece covers the causes behind each issue, practical steps to correct them, a preventive maintenance framework, and the signs that call for a qualified pool maintenance company.

Water Quality and Chemistry Problems

Cloudy Pool Water

Cloudy pool water is caused by poor filtration, low free chlorine, incorrect pH or alkalinity, fine dust and suspended particles, and heavy swimmer loads.

How to fix it: Test the water and adjust chemical levels based on the measured results and product directions. Brush the walls, steps, and floor to dislodge particles. Vacuum settled debris. Clean or backwash the filter, depending on the filter type. Run the circulation system for an extended period. Use a water clarifier only when appropriate and strictly according to the product label.

Green Water and Algae

Green water and algae are due to low sanitizer levels, poor circulation, high water temperature, organic debris buildup, and filter problems.

How to fix it: Remove large floating debris. Test the water and balance pH and alkalinity first. Brush all affected surfaces thoroughly, paying attention to steps, corners, and shaded areas. Apply the appropriate chlorine treatment based on water test results and product directions. Run the filtration system continuously during treatment. Vacuum debris once the water begins to clear. Retest and confirm safe chlorine and pH levels before allowing swimmers back in.

Low pH

Low pH can be caused by rainwater, certain sanitizing products, and organic contaminants, which can lower pH over time, leading to skin and eye irritation, corroded metal fixtures, damage to plaster and tile grout, and rapid chlorine loss.

How to fix it: Test pH and total alkalinity. Add the appropriate pH-increasing product according to the measured pool volume and the product’s manufacturer directions. Circulate water for the recommended period. Retest before making another adjustment, and add chemicals in measured increments.

High pH

This is caused by high total alkalinity, certain sanitizers, aeration from fountains or water features, and overcorrection from previous chemical additions, which reduce chlorine effectiveness and cause cloudy water and scale buildup on surfaces and equipment.

How to lower it: Test the water. Add an approved pH-reducing product according to product instructions and pool volume. Allow the water to circulate. Retest and make gradual corrections rather than a single large dose.

Strong Chlorine Smell (Chloramines)

A strong chemical smell near the pool usually signals chloramines, which form when free chlorine reacts with nitrogen-containing compounds in sweat, sunscreen, and body oils.

How to fix it: Test both free chlorine and combined chlorine. If combined chlorine levels are elevated, apply a corrective oxidation treatment (breakpoint chlorination) per test results and product directions. Improve circulation.

Equipment, Filtration, and Circulation Failures

Weak Water Circulation

This problem includes weak return jet flow, debris settling faster than normal, recurring algae in specific zones, and poor skimmer draw.

How to fix it: Empty the skimmer basket and pump strainer basket. Verify the water level is at the correct height for skimmer operation. Inspect the filter for clogs or damage. Check valves for correct positioning and inspect return jets for blockages. If the flow remains weak after these checks, have the pump professionally inspected.

Pool Filter Problems

Sand filter issues: Channeling (water bypassing the sand bed), cracked or damaged laterals, or backwash valve malfunctions.

Cartridge filter issues: Heavily clogged or physically damaged cartridges that no longer respond to cleaning.

DE filter issues: Torn or deteriorated grids and incorrect DE media levels, both of which reduce filtration capacity.

Consider replacing the filter when it causes recurring water clarity problems despite proper maintenance, when internal components are physically damaged, or when the filter has aged to the point of declining performance.

Pool Pump Is Noisy or Not Working

This may be caused by blocked baskets, air entering the suction line, low water level, worn bearings, and motor failure.

Check the water level, the condition of the pump basket, visible leaks at fittings, and any unusual sounds (grinding, screeching, or cavitation). Stop the pump and call a professional when there’s a burning smell from the motor, any sign of electrical problems, severe vibration, or persistent loss of prime after checking the water level and basket.

Pool Heater Is Not Heating

Possible causes include restricted water flow due to a dirty filter, incorrect thermostat settings, sensor or electrical faults, or a heat pump operating outside its effective temperature range. Electrical, gas, and internal heater components involve safety risks. Qualified technicians should handle these repairs.

Pool Leaks and Surface Damage

Water Level Keeps Dropping

Signs of an actual leak include water loss that exceeds evaporation, wet or soft ground near the pool, visible cracks in the shell, air bubbles in the circulation system, and unexplained increases in water bills. Professional leak detection methods include pressure testing plumbing lines, dye testing at suspected crack points, visual plumbing inspections, and equipment connection checks.

Cracked or Missing Pool Tiles

Damaged pool tiles are often due to age, ground movement, waterline chemical deterioration, poor original installation, and temperature-related expansion and contraction. Cracked or missing tiles expose sharp edges, allow water to penetrate behind the tile bed, and accelerate damage to adjacent tiles and the underlying pool structure.

Pool Surface Stains

Organic stains from leaves, algae, and plant debris typically appear as brown or green discolorations. Metal stains from dissolved iron, copper, or manganese appear as rust, blue-green, or dark marks on the pool finish. Test the water and identify the likely stain source before selecting a treatment, since applying the wrong chemical or scrubbing a metal stain with an acid intended for organic stains can damage the pool finish.

Cracks in the Pool Surface

Cosmetic cracks: Fine surface crazing in plaster or aggregate finishes. Usually superficial and not associated with water loss.

Structural cracks: Wider cracks, cracks that grow over time, or cracks accompanied by water loss. These may indicate ground movement or structural stress.

Professional inspection is necessary when there are recurring cracks after patching, measurable water loss, and any visible shifting or displacement of the pool shell.

How to Prevent Common Pool Problems

Follow a Weekly Home Maintenance Routine

Skim the water surface daily or as needed. Brush walls, steps, and the waterline weekly. Vacuum the pool floor. Test water chemistry at least twice per week. Check and maintain the correct water level. Empty skimmer and pump baskets. Inspect water clarity visually each day.

Clean the Pool Filter Regularly

Follow the filter manufacturer’s cleaning schedule. Monitor the pressure gauge and clean or backwash when pressure rises to the recommended threshold above the clean baseline. Increase cleaning frequency after dust storms, sandstorms, or periods of heavy pool use.

Inspect Pool Equipment

Listen for unusual pump sounds during operation. Check pipe connections and fittings for leaks. Monitor return jet flow and skimmer draw as indicators of circulation health. Inspect pool lights and water features periodically for proper operation.

Respond Quickly After Sandstorms

Remove surface debris promptly. Allow fine particles to settle when appropriate before vacuuming (vacuum slowly to avoid resuspending sand). Inspect and clean the filter. Test and rebalance water chemistry, as sand and dust events can shift pH and increase chlorine demand.

Schedule Preventive Professional Servicing

Scheduled inspections by a qualified pool maintenance company identify worn equipment, developing leaks, filter degradation, and chemical system issues before they become major repairs. It’s especially valuable in Saudi Arabia, where climate conditions can lead to pool problems that can compound quickly without intervention.
