Common Troubleshooting for Commercial Pool Sand Filters: Quick Solutions to Leaks, Abnormal Pressure, and Other Problems

Introduction

In commercial swimming pool facilities, it is very important to meet the demand of continuous clean water in order to meet safety standards and customer expectations. Sand filters are known for providing reliable mechanical filtration by trapping suspended particles and ensuring the supply of clean and safe water. Like all other mechanical systems, mechanical filtration is also vulnerable to occasional problems like leaks in the system and abnormal pressures. These occasional problems result in disturbing pool performance if not addressed properly.

In this article, the most common troubleshooting methods for the commercial pool sand filters are highlighted. In this article practical solutions to most common problems in sand filters are discussed, these solutions ensure the smooth operation of the pool and reduce down time. It also highlights elements of the product that increase efficiency and dependability, drawing on industry knowledge and tried-and-true methods. At the end we will introduce to you Poolking, one of the reliable and globally recognized sand filter suppliers, known for providing high performance sand filtration systems for commercial pool facilities.

Role of Commercial Sand Filters

Considering reliability, efficiency and simplicity of sand filters, they are most widely used in commercial pool facilities. They operate of mechanical principle, water is forced to pass through a bed of filtration media such as sand quartz and glass beads, leaving the impurities such as oils and suspended particles trapped in the filtration media bed, and providing clean and clear water to the pool.

Due to their ability to handle large volumes of water, sand filters are optimal choice for water parks, training facilities, and commercial swimming pools. However, when operational problems arise, there can be much loss in terms to increased downtime and compromised water quality. Identifying and rectifying these issues at early stage not only restores efficiency but also increases working life of the equipment.

Common Problems in Commercial Pool Sand Filters and Their Solutions

Leaks Around the Filter Tanks and Connections

Leaks are one of the most frequently occurring problems in the commercial sand filters, leaks usually occur around tank body, multiport valves, and connections. Causes of leaks in the system are usually worn out O rings, damaged housings, and improperly sealed connections.

The solution for leaks is to properly inspect all the connections and loose fittings. Replace faulty O rings with manufacture approved parts and ensure fittings are tightened according to standard specifications. In case of crack on sand filter tank, immediately replacement of the tank is necessary for maintaining safety standards. Regular inspection of valves and seals is necessary to avoid leakage problems.

Abnormal Pressure Readings

Pressure gauges on sand filters are important tools to get the system insight. Normal operating pressure should remain stable in balanced sand filtration system. A sudden rise in pressure indicates clogging in the filtration media bed, and drop in pressure indicates blockages in the suction line and pump malfunction.

If the pressure is high, do backwashing of sand filtration system to remove clogged particles. If pressure gauges show low pressure, inspect the pump and suction pipe for blockage and air leaks. Regular backwashing and filter media replacement every 3 to 5 years reduce pressure related problems significantly.

Cloudy Water Despite Filtration

It is one of the most frustrating problems for commercial pool facilities, as sand filter seems operating but water gets cloudy. This issue usually arises due to worn out filtration media and improper grain size selection.

The solution of this problem is to inspect the quality of filtration media, and do replacement if necessary. Commercial pool facilities should consider advanced glass beads media for their systems for ultra fine filtration. Also ensure that the water flow rate of the system is as per manufacturer’s specification, sometimes large capacity pumps force large volume of water making filtration ineffective.

Backwashing Problems

Improper backwashing leads to reduced sand filter performance. Sometimes dirty water gets into the pool due to incomplete backwashing.

Prior to backwashing, make sure the pump is operating at the proper speed, check the lines for obstructions, and make sure the multiport valve is set correctly. Automated backwashing that is activated by pressure sensors in high-use systems can ensure consistent performance while saving electricity and water.

Sand Entering the Pool

Sand particles flowing back into the pool is another common problem in commercial swimming pools. This problem indicates broken laterals inside the filter tank and incorrect sand grade.

Shut down the sand filtration system and inspect lateral inside filter tanks. Replace damaged parts and always use filtration media according the manufacturer’s specifications to avoid recurring issues.

Preventive Maintenance Practices

Preventive maintenance is very important to ensure long-term operation and reliability of commercial sand filters. Commercial pool facilities should do regular inspection for damaged parts and detect early sign of wear. Backwashing should be done considering the pressure reading rather than fixed schedule, as it saves water and energy. Timely replacement of filtration media is also very crucial in long-term reliability and performance of sand filters. Calibration of pressure gauges is also necessary to ensure accurate pressure readings. By following these preventive maintenance practices, commercial pool facilities can significantly reduce downtime, increase working life of sand filtration systems, and ensure supply of clean and clear water continuously.
