Pool Maintenance Schedule for Yuma Homeowners

What to do each week, each month and every few months, then how the Yuma year changes the list: long hot months, monsoon dust, mild winters and the months many owners are away.

A pool maintenance schedule is just a list of small jobs done on time, so the water never gets far from clean and balanced. The national lists are a good start, but a Yuma pool lives through months of triple-digit heat, dust that blows in during the monsoon, very hard tap water, and a long winter when many owners are here, followed by a summer when many of them are not. This guide gives you the basic weekly, monthly and quarterly list, then a Yuma calendar that shows when each part of the year needs extra attention.

A note on who wrote this: Yuma Pool Cleaning Pro does no pool work itself. It runs a free number that puts callers through to an independently owned pool company in the Yuma area, and that company handles the visits, the pricing and the billing if you decide to hand the schedule over.

The basic pool maintenance schedule: weekly, monthly, every few months

The pool industry trade group, known as the Pool and Hot Tub Alliance (PHTA), publishes a homeowner checklist. Here it is in short form, with a note on why each task matters.

Every week

Test chlorine, pH and alkalinity with a test kit, then adjust.
Brush the walls and floor. Brushing lifts algae before it can take hold.
Vacuum the floor.
Empty the skimmer and pump baskets so water flows freely.

Every month

Clean the filter as needed: backwash a sand filter or rinse a cartridge, following the maker's directions.
Shock (oxidize) the water.
Look over the pump, filter and heater for leaks, noise or wear.

Every few months

Test total dissolved solids, the minerals and other material that build up in the water over time.
Clean the tile and grout at the waterline.
Keep a simple log of test results and work done.

Testing deserves its own line. The CDC page on home pool water asks owners to check chlorine and pH no less than two times each day, with more checks when the pool is crowded. Few households test that often, which is one reason a quick check between weekly visits is worth the minute it takes. The CDC targets for a home pool are:

pH7.0 to 7.8. Chlorine works more slowly as pH rises.
Free chlorineat least 1 part per million (ppm).
Free chlorine with stabilizerat least 2 ppm when cyanuric acid or a stabilized chlorine product is in use.

A Yuma pool calendar, season by season

In Yuma the weekly tasks never take a season off. The weather decides how much extra each month adds. The dates below come from National Weather Service (NWS) climate normals for Yuma, the NWS monsoon season, and Yuma County.

Yuma pool care calendar by season, with weather facts and what to watch
Time of year	What the weather is doing	What to watch at the pool
November to February	Mild. The NWS normal for nights at or below freezing is about 0.1 a year.	Keep the weekly routine. Weaker winter sun means less chlorine lost to sunlight. On an APS time-of-use plan, the winter super off-peak window is 10 a.m. to 3 p.m. on weekdays.
March to late April	Warming fast. The average first 100 degree day is April 25.	Have the pump, filter and timer checked before the heat arrives. Clean the filter and look for scale at the tile line.
Late April to mid June	Hot and very dry, with strong sun.	Water drops faster, so check the level at the skimmer often. Chlorine use climbs. Set the pump to run outside the APS on-peak hours of 4 to 7 p.m. on weekdays.
June 15 to September 30	Monsoon season. Dust storms pick up sharply in July with the summer thunderstorms. About 25 days a year reach 110 degrees, mostly June to August; the July average high is 106.7 degrees.	Skim and empty baskets after every storm. Expect the filter to load up faster. Test the water after dust or rain blows in.
October	The average last 100 degree day is October 6, then nights cool off.	A good month for a filter cleaning, a tile check and a look at any equipment that struggled over the summer.
Winter months	Winter visitor season. Yuma County says seasonal visitors swell its population by about 90,000.	Owners who leave in spring need weekly care arranged for the hot months they are away.

Over a full year, Yuma averages about 118 days at or above 100 degrees, by the NWS 1991 to 2020 normals. That is a long stretch of hard work for a pool's chemistry and equipment, and it is why the summer rows above carry the most tasks.

Leaving for the summer, coming back in the fall

A pool left alone through a Yuma summer can go from clear to green while its owner is far away. Two short checklists help.

Before you leave for the summer

Arrange weekly care with a pool service company or a reliable person, and leave gate access and a phone number.
Empty the skimmer and pump baskets and clean the filter as the maker directs.
Confirm the timer runs every day and avoids the APS on-peak hours.
Fill the water to about the middle of the skimmer opening.
Store chemicals in their original containers, dry, out of the sun, secured from children and pets, and within the label's temperature limit. A closed garage gets very hot in summer.
Check that the pool gate still closes and latches by itself.

When you come back in the fall

Look before anyone swims. If you cannot see the floor clearly, keep everyone out, especially children.
Empty the baskets and read the filter pressure gauge.
Check the timer, the water level and the equipment pad for drips or leaks.
Look for white crust along the tile line.
Test the water, or have the pool company test it, before the first swim.
If the water is green or cloudy, read my pool is green, how do I fix it.

Sun, evaporation and hard water: the Yuma part of pool water maintenance

Sun and stabilizer

Sunlight is one of the factors the CDC names for falling chlorine readings. Visit Yuma reports that the sun shines here about 91 percent of daylight hours. On the EPA and NWS UV index scale, a reading of 11 or more counts as extreme. Many pools use cyanuric acid, often called stabilizer or conditioner, which forms a weak bond with chlorine and shields it from the sun. The tradeoff is that chlorine kills germs more slowly with stabilizer present, which is why the CDC asks for at least 2 ppm instead of 1 when it is used. How much stabilizer a pool should carry is a question for the pool technician who tests it.

Evaporation and topping off

The EPA WaterSense program estimates that a typical uncovered pool can lose 12,000 to 31,000 gallons a year to evaporation, depending on where it is, and that a pool cover can prevent up to 95 percent of that loss. In dry desert heat, plan to check the water level at least weekly in summer. A level that sinks far down the skimmer opening lets the pump draw air. If the drop seems too fast, a bucket test (a bucket of pool water set on a step, with both levels marked) shows whether you are seeing evaporation or a possible leak.

Hard water and the tile line

City of Yuma water comes from the Colorado River, and the city's water FAQ calls it hard: 18 to 22 grains per gallon. Evaporation takes only water, leaving calcium and other minerals in the pool, and each top-off brings in a fresh dose. Month after month, the result is a pale, rough crust on the tile right at the water line. Brushing the tile on schedule slows it down. Heavy scale is a separate job; see pool tile cleaning and calcium scale.

Pump timers and APS hours

APS current time-of-use plans charge the most from 4 to 7 p.m. on weekdays, and APS advises running the pool pump off-peak. From November to April, APS plans add a super off-peak window from 10 a.m. to 3 p.m. on weekdays, and APS says running the pump then could save a customer up to $120 a year. Older APS plans use a 3 to 8 p.m. peak, so check your bill. In Wellton, electricity comes from the Wellton-Mohawk Irrigation and Drainage District, and in the Foothills or Gadsden your bill names your provider.

Pool maintenance tips and tricks that are safe for homeowners

Skim before you brush. Taking leaves and dust off the top first keeps them from sinking while you work.
Note the filter gauge when the filter is clean. Write that number down. Your filter maker's directions say how far above it the pressure can climb before cleaning.
Mark the water line on a calm day. A piece of tape at the skimmer makes fast drops easy to spot.
Check the timer after any power outage. Make sure the clock still shows the right time, so the pump runs at the hours you chose.
Keep the deck and equipment pad clear. Gravel, palm fronds and blown debris end up in the baskets.
Reset a tripped GFCI or breaker one time. If it shuts off again, leave the power off and phone a pro. Do not open the equipment or touch wiring.
Keep a log. Dates, test readings and anything odd you noticed help a pool technician find a pattern.

Chemical safety first. The CDC says never mix pool chemicals with each other or with anything else; chlorine and acid together can make toxic gas. Keep products in their original labeled containers, dry, cool, out of direct sun and secured away from children and pets, and follow the label. Leave acid work to a professional. If you ever smell gas near a pool heater, leave the area right away, do not use switches or anything that could spark, and from a safe distance call 911 and Southwest Gas at 877-860-6020.

Handing the schedule to a pool company

If the weekly list is more than you want to keep up with, or you will be away for the summer, the line can put you through to a local company that offers regular service. Here is how a call works.

Call the numberAn automated assistant answers (928) 615-5224 at any hour, every day of the year.
Describe the poolCloudy or green water, a pump making noise, crust on the tile, a heater that will not fire, and which part of the Yuma area you are in.
Get put throughThe call goes to an independent, locally owned pool service company in the Yuma area, which hears a short summary before it picks up.
Deal with them directlyThat company inspects, quotes, does the work and bills you. If it misses the call, your name, number, area and pool problem are passed on for a call back.

When the schedule slips

Missed weeks happen. What to do next depends on what the water looks like.

Cloudy or slightly green: the step-by-step guide my pool is green, how do I fix it explains the causes and safe first checks.
Dark green, swampy or the floor is hidden: that usually takes a green pool cleanup over more than one visit. Keep children away until the water is clear. Yuma County Public Health asks residents to report green, neglected pools because they breed West Nile mosquitoes.
Ready to stop doing it yourself: see weekly pool service in Yuma or a one-time pool cleaning, and the published price ranges in the pool maintenance cost guide.

Away for the summer or behind on the weekly list? Call any hour and say where in the Yuma area the pool is. The local company you are put through to looks at the pool and quotes its own price.

Common questions

What is a good pool maintenance schedule?

The Pool and Hot Tub Alliance, an industry group, suggests a simple rhythm. Every week: test the water and adjust, brush the walls and floor, vacuum, and empty the baskets. Every month: clean or backwash the filter as needed, shock, and look over the pump, filter and heater. Every few months: test total dissolved solids and clean the tile. In Yuma, add extra skimming after dust storms and a regular look at the water level in the hot months.

How often should you maintain your pool?

At least once a week for the full list of tasks, by the Pool and Hot Tub Alliance schedule. Water testing should happen more often than that: the CDC home pool page recommends a chlorine and pH test two or more times daily, plus extra tests on busy swim days. A weekly service visit covers the heavy work, but a quick check of the water between visits still helps.

How often should you clean your pool in the winter in Yuma?

Keep a weekly routine. Yuma winters are mild, and the National Weather Service normal for freezing nights is about 0.1 a year, so pools here are not closed for winter the way they are in cold places. The water still needs chlorine, the baskets still fill and the filter still runs. Cooler water and a lower sun mean the work is usually lighter than in July, but it does not stop.

What should I do with my pool before I leave Yuma for the summer?

Arrange for someone to care for it every week while you are gone, since an untended pool can turn green in the summer heat. Before you leave, empty the baskets, clean the filter as the maker directs, check that the timer runs every day, fill the water to the middle of the skimmer opening, and store any chemicals in their original containers, secured and away from heat. Leave gate access and a phone number with whoever will look after it.

Is pool maintenance required all year in Yuma?

The schedule on this page is practical advice, not a legal rule, but the water needs care all year. Yuma County Public Health says green, unmaintained pools are a major breeding place for West Nile mosquitoes, and a murky pool hides the bottom, which is a drowning risk for children. Year-round weekly care is the simplest way to avoid both.

Schedule slipping? Talk to a local pool company

Ring the line at any hour, say what is happening with the pool and where in the Yuma area it is, and the call is passed to an independent, locally owned pool service company. That company looks at the pool itself and sets its own price.
