Build a Commercial Pool Preventive Maintenance Schedule

Build the schedule from three things: the manuals for your equipment, its service history, and your health code. Each task then needs an owner, a clear way to tell when it is due, and a record of the work. The CDC's Model Aquatic Health Code (MAHC) is a good outline to start from.

What does the CDC say about maintenance plans?

The CDC's page on operating public pools says to maintain filtration and recirculation systems according to manufacturer recommendations.

The 2024 MAHC, section 5.4.2, asks for a written preventive maintenance plan for each pool, kept at the facility. The plan should list how often the operator inspects, maintains, and replaces the recirculation and water treatment parts. The same section asks for the equipment manuals to be kept on site. If a manual does not exist, the facility writes its own operating steps for that equipment.

Label each task with its source so staff can tell a legal requirement from a choice your team made.

What belongs on your equipment list?

MAHC section 5.4.2.2 lists what an equipment inventory should hold for each piece of mechanical equipment:

• Equipment name and model number.
• Manufacturer and contact information.
• Local vendor or supplier and technical contact, if there is one.
• Replacement or service dates and details.

Add where the equipment sits and where its manual is kept. Most lists cover pumps, filters, chemical feeders, controllers and heaters. To open a record from the pool deck, see our guide to equipment QR and NFC lookup.

Mark unknown details as unknown. A guessed model number can send someone to the wrong manual. Add a task to confirm it instead.

What checks should happen every day before opening?

MAHC section 6.4.1.3.1 lists a daily preventive maintenance check before opening. The qualified operator or a responsible supervisor makes sure it is done and logged. Some of its items:

• Drain covers and other suction outlet covers are in place, secure, and unbroken.
• Skimmer baskets, weirs, and suction outlets are not blocked.
• Recirculation and disinfection systems, controllers, and probes are working as required.
• Underwater lights have no exposed wires or water inside.
• Gates, fences, and self-latching locks work properly.
• First aid supplies are stocked and emergency phones work.
• The pool bottom is clearly visible.

Section 6.4.1.3.2 adds monthly tests of GFCI devices and a visual check of accessible bonding conductors every 6 months, or sooner if building work nearby disturbs them. The building-work rule is easy to miss: a deck repair near the pool should start a bonding check.

How do you turn a manual into scheduled work?

Read each care task in the manual and note what makes it due. Some tasks follow the calendar. Others depend on running hours, a reading such as filter pressure, or a problem found during a check. Ask the manufacturer or your service company when the timing is unclear.

Here is a template you can copy. The MAHC rows show the model code; swap in your state's rule where it differs.

Task	When due	Source	Who does it	Record
Daily pre-opening check	Every day before opening	MAHC 6.4.1.3.1	Qualified operator or supervisor	Daily log
GFCI test	Monthly	MAHC 6.4.1.3.2	Trained staff	Maintenance log
Bonding wire visual check	Every 6 months, and after nearby construction	MAHC 6.4.1.3.2	Trained staff you name	Maintenance log
Filter cleaning	As the manual says	Filter manual	Trained operator	Service note
Pump service	As the manual says	Pump manual	Service company	Technician report

Electrical work, chemical systems and pressurized equipment go only to people trained on them.

How should you use past repair records?

Read earlier service notes before setting the next round of work. Look for repeated concerns, unfinished recommendations, and parts that were ordered but not installed. Ask a qualified service person whether the schedule needs to change.

For example, say a pool has three notes about the same pump noise. Those notes are a reason to ask for a proper check. They do not tell you the cause.

Keep water records nearby during that review. Our guides to commercial pool chlorine ranges and commercial pool pH ranges explain which limits apply. A water reading alone does not diagnose an equipment fault.

How do you handle overdue or unfinished jobs?

Keep overdue work separate from finished work waiting for review. For each unfinished job, record the reason, who knows about it, and the next step. "Waiting for a part" is more useful when it also names who is checking the order.

If equipment is unsafe or cannot do its job, ask the qualified operator and the manager about closing the pool. A booked repair visit does not make it fine to keep operating.

What should prove a task is complete?

A completion note should say what was done, when, and by whom. Attach the technician's report and any replacement part details. Leave recommendations for later work open until someone reviews them.

The MAHC, section 6.4.1.2.1, says facility records should be kept for at least 3 years and shown to the health department when asked.

Poolean tracks scheduled maintenance, repair orders, and chemical and parts requests for each pool. Its maintenance tools also keep season opening and winterization records. You can book a 30-minute call to see how those records are organized.

The short version

• Start with the manual for your exact equipment.
• Build an equipment list with model, maker, vendor, and service dates.
• Use the CDC's model code as an outline.
• Assign each task to someone with the right training.
• Keep records of finished and unfinished work, for at least as long as your code requires.
