How to catch predictable problems before they affect your schedule
Key Takeaways
- Equipment that runs smoothly at reduced capacity often reveals issues under full load.
- Most busy season problems are predictable and preventable with early assessment.
- Getting ahead of these issues helps maintain consistent programming and gives you more control over repair timing and costs.
After 60 years in this industry, we’ve seen it happen the same way. As usage increases, equipment that operated comfortably at reduced capacity is asked to run longer, harder, and more consistently. Pumps, filters, and heaters that appeared stable through the winter or slower season can begin to struggle once they’re operating under sustained load. Chemical feeders ramp up to maintain balance with higher numbers of guests in the water. Deck and safety details that were easy to overlook during quieter months become more noticeable as activity returns.
Understanding equipment performance and usage progression can help facility leaders focus on the most necessary updates and repairs to address. Below are the six most common problems that arise in the busy season and what you can do to get ahead of them.
1. Pump Motor Failures
Pump motors that have been running at partial capacity through the winter often develop bearing wear, seal degradation, or overheating issues once they’re pushed back to full operation. You might notice unusual sounds or vibration during startup.
This is one of the first things our technicians check during spring assessments. Early bearing wear is easy to miss if you’re not listening for it. Catching it in April means scheduling a replacement on your terms, rather than scrambling in July.
What you can do: Listen for grinding or whining sounds during startup. Check for leaks around the motor housing and monitor amp draw if you have the equipment. Motors showing early warning signs are good candidates for replacement before peak season, when scheduling repairs becomes harder and costs typically increase.
2. Filter Performance Issues
Filter media, grids, or cartridges that handle winter loads adequately may struggle under continuous circulation in the busy season. You’ll often see increased pressure differentials and reduced water clarity. DE filters may show channeling; sand filters may have developed hardpan.
We often find filter issues during assessments that pressure gauges alone wouldn’t catch, like early channeling or media degradation that only shows up on visual inspection.
What you can do: Compare your current influent and effluent pressure readings to baseline numbers. A pressure differential above your normal operating range indicates it’s time to inspect the filter internals. For sand filters, check for channeling by observing backwash clarity. Plan media replacement or grid cleaning before your facility gets busy.
3. Chemical Controller Drift
Controllers and sensors can drift out of calibration over time, and these errors may not always be noticeable.
What you can do: Prior to ramping up to peak season, calibrate controllers against a fresh, high-quality test kit. Replace probes that are past their service life or showing erratic readings. Check the manual for new probe recommendations. Document your calibration settings and establish a regular verification schedule. Monthly checks during peak season are a reasonable baseline for most facilities.
4. Water Quality Baseline Problems
Facilities that reduced chemical treatment during lighter months may find their water balance is off. Calcium hardness, total dissolved solids, or cyanuric acid levels may have drifted outside optimal ranges, making consistent chemistry difficult to maintain even with properly calibrated equipment. Water testing during our assessments often reveals baseline imbalances that explain ongoing chemistry struggles, even when equipment is functioning properly.
What you can do: Conduct comprehensive water testing beyond your standard daily checks. Measure calcium hardness, total alkalinity, TDS, and stabilizer levels. Calculate your Langelier Saturation Index to understand where your water stands. Addressing balance issues now, when you can make gradual adjustments, is far easier than correcting problems under peak demand.
Be sure to check local code because there may be certain testing requirements that must be met when your facility is open to patrons.
5. Automation and Valve Failures
Chemical feed systems, actuator valves, and control automation can develop problems when regular cycling resumes after months of lighter use. Valves may stick or actuators may fail to complete their rotation. Communication errors between controllers and equipment also become apparent.
We test every automated valve during facility assessments because these failures are easy to miss until they cause a problem. An actuator that hesitates today often fails completely within a few months.
What you can do: Manually cycle all automated valves and verify they complete full rotation. Check chemical feeder operation by running through a normal dosing cycle. Review controller error logs for any communication failures. Replace actuators or valves that show hesitation or incomplete travel. These problems typically get worse, not better.
6. Deck and Safety Equipment Deterioration
Seasonal changes take a toll on deck surfaces, handrails, ladders, rails, and ADA lifts. What looked acceptable in fall may now present trip hazards, loose fittings, or compliance concerns. These details are easy to overlook when you’re focused on mechanical systems, but they’re often the first things people notice when activity picks up.
Our assessments include a full review of deck and safety equipment, and checking for compliance. These are the kinds of details that rarely cause emergencies, but can create liability issues or inspection problems if they’re missed.
What you can do: Walk the entire deck area with fresh eyes. Check all handrails for secure mounting. Inspect ladder treads and anchors. Review safety signage for fading or damage. These items are straightforward to address now and become much harder to schedule once programming is in full swing.
Planning Your Pre-Season Assessment
Most facilities can complete a walk-through covering these six areas in a few hours. You don’t need to fix everything at once. But you do need to know what key items might fail, and what to address now versus later.
The difference between a walk-through you do yourself and a professional assessment is depth. Your team knows your facility, but our technicians have seen hundreds of pools and pump rooms across all sorts of venues that deal with varying capacity, including municipal pools, YMCAs, water parks, and fitness centers. We know what early failure looks like because we’ve tracked how equipment ages across different facility types and operating conditions.
Identifying which equipment is showing wear and which repairs to prioritize lets you strategically plan around your schedule rather than react to emergencies.
For facility managers who want support with this process, Landmark’s AquatiCare service plans offer proactive maintenance tailored to your specific facility. Our Certified Pool Operator (CPO) technicians provide in-depth assessments of mechanical, chemical, and deck systems, identifying potential failure points and helping you address them early—before they disrupt operations.
