The Weekly Pool Maintenance Checklist

A clean, safe pool doesn't happen by accident. It takes consistent, methodical care every single week. Skip a task here or there, and you'll be fighting algae, cloudy water, and expensive equipment problems before you know it.

At JAYS Pool Service, we've spent years keeping pools across Niagara Falls and the surrounding area in top shape. This is the same checklist we use on every service call. Follow it every week, and your pool will stay swimmable, safe, and looking great all season long.

1. Skim the Surface

Start at the top. Leaves, insects, pollen, and debris floating on the surface will eventually sink, stain your liner, and clog your filter if left alone.

• Use a skimmer net with a telescoping pole to reach across the entire pool
• Skim in a sweeping motion, working from one end to the other
• Don't forget the corners — that's where debris collects first
• Do this first thing in the morning, before swimmers and wind churn debris below the surface

If you have trees near your pool, you may need to skim more than once a week. A heavy debris load can throw off your chemical balance and put unnecessary strain on your pump.

2. Vacuum the Pool Floor

Once the surface is clear, move to the bottom. Dirt, sand, and organic matter settle on the pool floor and create a breeding ground for bacteria and algae.

3. Brush the Walls and Tile Line

Vacuuming alone won't get everything. Algae and calcium deposits cling to pool walls, especially along the waterline and in corners. Brushing dislodges them so your filtration system can do its job.

• Use a nylon brush for vinyl or fiberglass pools — a steel brush will scratch the surface
• For concrete/gunite pools, a combination nylon/stainless brush works well
• Brush from the tile line downward, working in sections
• Focus on areas with poor circulation: behind ladders, in corners, near steps

Brush before you vacuum. That way, anything you dislodge settles to the floor where your vacuum can pick it up.

4. Empty the Skimmer and Pump Baskets

Full baskets restrict water flow, reduce filtration efficiency, and force your pump to work harder than it needs to. This is a two-minute task that prevents major headaches.

1. Turn off your pump before opening the pump basket lid
2. Remove the skimmer basket and dump contents into a bag or compost
3. Rinse the basket with a hose to remove any stuck-on debris
4. Open the pump basket (usually near the motor), empty and rinse it the same way
5. Inspect the basket for cracks — replace if damaged
6. Reassemble, ensuring the lid O-ring is seated properly to prevent air leaks

5. Check Filter Pressure

Your filter's pressure gauge is one of the most important diagnostic tools you have. A rising pressure reading tells you the filter is getting clogged and needs attention.

When the gauge reads 8–10 psi above your clean baseline pressure, it's time to backwash (for sand and DE filters) or clean the cartridge (for cartridge filters).

What to look for:

• Normal pressure: Within your baseline range — filter is working properly
• High pressure: Filter is dirty — backwash or clean the cartridge
• Very low pressure: Could indicate a blockage upstream — check baskets and impeller
• Erratic pressure: Air in the system — check for suction leaks

6. Test and Balance Water Chemistry

Chemical balance is what keeps your water safe, clear, and gentle on skin and equipment. Test your water at least once a week — more often during hot weather or heavy use.

Use a reliable test kit or test strips. If any levels are off, adjust immediately — waiting gives algae and bacteria a head start. Always add chemicals one at a time, never mix them directly, and run the pump for at least an hour after dosing.

7. Backwash When Needed

If you have a sand or DE filter and the pressure gauge tells you it's time, backwash the filter to flush out trapped debris. The process is straightforward:

1. Turn off the pump
2. Set the multiport valve to "Backwash"
3. Turn the pump back on and run until the sight glass runs clear (usually 2–3 minutes)
4. Turn off the pump and switch to "Rinse" for 30 seconds to settle the sand bed
5. Return to "Filter" mode and turn the pump on

If you have a cartridge filter, remove the cartridge, hose it down thoroughly, and soak it in filter cleaner if needed. Replace the cartridge annually or when you notice a significant pressure increase that cleaning doesn't fix.

8. Inspect Pool Equipment

Take five minutes each week to walk around your equipment pad and visually inspect everything:

• Listen for unusual noises from the pump motor — grinding or squealing means trouble
• Check for water leaks around the pump, filter, and fittings
• Ensure return jets are angled properly to create circulation
• Verify the timer is set correctly and operating as expected
• Check pool lights for proper operation
• Look for any signs of rust or corrosion on metal components

Catching a small issue — like a tiny leak or a worn pump seal — can save you thousands in equipment replacement costs. Prevention is always cheaper than repair.

Stay Consistent

The secret to a great-looking pool isn't one heroic weekend of cleaning. It's doing these eight steps consistently, week after week, all season long. A well-maintained pool uses fewer chemicals, runs more efficiently, and lasts longer.

Not everyone has the time or desire to handle this themselves — and that's perfectly fine. The important thing is that it gets done right.
