Pool service in Chandler, AZ comes down to one fact more than any other: the water that fills your pool is already hard before the sun ever touches it. Here is what Chandler's water, rules and housing mean for a backyard pool, and what happens when you ring the free line.
Phoenix Pool Cleaning Pro does not clean or repair pools. When you ring (623) 240-0428, an automated assistant takes a quick description of the pool trouble and transfers you to an independent, locally owned pool service company that takes Chandler calls. That company comes out, gives you its price, does the work and bills you itself.
Chandler: a farm town that turned into a chip-making city
Chandler was founded in 1912 and incorporated on February 16, 1920. For decades it stayed small, with only about 3,800 residents in 1950, even after Williams Air Force Base opened nearby in 1941. Then the farm economy gave way to electronics and computer chip plants, and the population took off: about 30,000 in 1980 and 275,987 in the 2020 census.
That timeline tells you a lot about the pools. A city that grew that fast after 1980 built most of its homes, and most of its backyard pools, in a short window. Many of those pools now have original plumbing and plaster and their second or third pump. When you call about a Chandler pool, it helps to know roughly when the house was built, because the age of the finish and equipment shapes what a pool technician looks for first.

Chandler pool service and maintenance people call about
Most Chandler calls fall into four groups. Routine pool cleaning and weekly maintenance keeps chlorine up and dust off the floor through a long, hot season. Pool tile cleaning deals with the white crust that hard water leaves at the waterline. A dirty filter is often the first casualty of a dust storm, which is what pool filter cleaning covers. And when a pump, heater, timer or salt system quits, pool equipment repair is the place to start.

Pool Cleaning and Weekly Maintenance
Skimming, brushing, baskets, vacuuming and water testing week after week, and why heat, dust and hard water make the routine matter here.

Pool Equipment Repair
The whole equipment pad: valves, timers and automation, salt systems, lights and fountains, and which jobs belong to a licensed contractor.

Pool Tile Cleaning
White calcium lines at the waterline: why they form so fast in the Valley, how bead blasting and other methods compare, and what can damage tile.

Pool Filter Cleaning
Cartridge, DE and sand filters, the pressure gauge rule of thumb, and why dust storms load filters fast.
Three rivers and a well field in every glass
Chandler does not lean on a single source. The city's water supply pages describe a blend, and each part leaves its mark in the pool.
Salt and Verde rivers
About 57 percent of Chandler's drinking water comes from the Salt and Verde rivers, delivered by the Salt River Project's dams, reservoirs and canals. The city's own surface water plant draws it from the Consolidated Canal.
The Colorado River
About 37 percent is Colorado River water, carried across the desert in the Central Arizona Project (CAP) canal. Chandler also shares a treatment plant, Santan Vista, with the Town of Gilbert.
Groundwater and stored water
About 6 percent comes from city wells. Chandler has banked surface water underground and built recharge basins and injection wells so it can pump stored water during a shortage.
What 16.5 grains of hardness means for a Chandler pool
Hardness is the calcium and magnesium dissolved in water. Chandler's water quality FAQ puts its tap water anywhere from about 5 to 20 grains per gallon depending on the source in use, with a citywide average of 16.5. The city's 2023 water quality report listed total hardness of 163 to 340 milligrams per liter, which it equated to 9.5 to 19.9 grains. The same FAQ notes that the U.S. Environmental Protection Agency has set no limit for hardness, which is not considered a health concern. For a pool, though, it matters a lot.
Here is why. A Chandler pool can lose a lot of water to evaporation in summer, and only the water leaves. The calcium stays behind, so every top off adds more minerals to a pool that already had plenty. When the water also runs warm and slightly high in pH, that calcium comes out of solution and sticks to the warmest, roughest surfaces: the tile line, the heat exchanger inside a gas heater, and the plates of a salt cell. Pool technicians use a measure called the saturation index (LSI) to judge whether water is likely to scale or to etch plaster, and they adjust pH and alkalinity to keep it near balance.

Because the source blend shifts, a Chandler pool filled in one season can test differently from the same pool refilled in another. That is a good reason to ask the company you are put through to how often it tests calcium hardness, not just chlorine and pH, and what it does when the number keeps climbing. Sometimes the answer is partly draining and refilling, which brings the city's drain rules into play.
Safe checks before you call
- Baskets. Empty the skimmer and pump baskets, especially after wind. With the pump off, a packed basket is the most common reason for weak flow.
- Filter gauge. Note the pressure reading and compare it with what it reads when the filter is clean. A big rise means the filter needs attention.
- Water level. The water should sit about halfway up the skimmer opening. Too low and the pump can pull air.
- Timer. Check that the timer or automation still has the right time after a power blip.
- Breaker or GFCI. Reset a tripped one once. If it trips again, leave it off and tell the company.
Chemicals and gas, safely. Never mix pool chemicals with each other. Store them apart in a dry, shaded spot out of children's reach and follow the label. If you smell gas near a pool heater, leave the area, do not touch switches or the heater, and from a safe distance call the Southwest Gas emergency number on your bill or 911.
Draining or backwashing a pool in Chandler
Chandler's stormwater rules are about keeping pool water out of the street. Storm drains carry water away untreated, and chlorinated, salty or dirty pool water is not supposed to reach them. The city's pool drainage guidance gives Chandler homeowners and pool companies clear lines to follow.
What Chandler allows
- Draining into the sanitary sewer cleanout on your own property, with no permit needed.
- Keeping backwash and drain water on your own landscaping.
- Refilling without notifying the city, though your water bill will show it.
What Chandler prohibits
- Pipes or hoses that run off your lot to the street, alley or other city right of way.
- Treating that line as a drain path: the city calls it a direct connection to the storm drain system.
- Street draining without asking: if you cannot find your cleanout, request an exception first.
The cleanout is a capped pipe on your own lot, usually close to the house. Chandler suggests draining no faster than about 12 gallons per minute, while noting that the safe rate depends on the drain line size, the distance to the sewer main and the condition of the pipes, and it says to shut the pump off at once if water backs up into the home, since that points to a blockage or too high a flow. For a safe rate, the city says a plumber may be needed. Even with a street exception, alleys are off limits, and water headed into an HOA retention basin needs that HOA's permission.

Pool fences, power and water savings in Chandler
Chandler's pool barrier rules
Chandler's building safety pages say every pool must be enclosed by a perimeter fence at least six feet high (and no more than seven), of masonry, concrete or decorative fencing such as wrought iron, and that an existing wood fence has to be replaced when a pool goes in. The fence cannot offer hand or foot holds, and the spacing between members cannot exceed one and three-quarter inches. Pedestrian gates must close and latch on their own, swing outward from the pool if there is no inner barrier, and have a latch more than 54 inches above the ground. Gates wider than 4 feet must stay locked. Chandler's Development Services department can confirm the details for a specific project.
Whatever the fence, never leave a child alone near a pool, and treat a green or cloudy pool as a hazard because no one can see the bottom. If yours has gone that way, the green pool cleanup page explains what a cleanup involves.
Electricity and gas
Chandler's own economic development material lists both SRP and APS as electric providers in the city, so which one bills you depends on your address. SRP's residential line, (602) 236-8888, answers around the clock for outages. Natural gas comes from Southwest Gas. Neither utility works on pool equipment: when the house has power but the pump sits silent, the fault lies with the pool equipment or the circuit feeding it.
Water conservation rebates
Starting January 1, 2026, Chandler cut its single family grass removal rebate from $2.00 to $1.50 per square foot and lowered the cap from $3,000 to $2,000, and you need the city's notice to proceed before any grass comes out. Confirm the current amount with the Water Conservation Office (480-782-3583) before you start. The city also offers a rebate of half the price of a qualifying smart irrigation controller, up to $250.

An automated assistant answers day and night. When the Chandler company is busy, it still gets your details so it can ring you back. You pay the company, never the line.
Help checking the license
Many Chandler pools are on their second or third set of equipment. This site shows you how to look up a company's license on the Arizona ROC search before repair work starts.

- Deal with them directlyThat company looks at the pool, quotes, does the work and bills you. If it cannot answer, your name, number, area and problem are passed along so it can call you back.
About this line: Phoenix Pool Cleaning Pro is a free phone line, not a pool company. It answers your call and connects you with an independent local pool service company, which inspects, quotes and does the work, and which you pay directly. Companies may pay a referral fee. You never pay the line. See how the line works.
Check the license first. Arizona's Registrar of Contractors (ROC) licenses contractors, and its residential classifications include R-6, Swimming Pool Service and Repair. Repairs, equipment replacement and resurfacing generally call for a licensed contractor; whether a cleaning-only service needs a license is not spelled out, so ask the ROC if it matters to you. Ask the company for its ROC license number and look it up on the ROC contractor search (opens in a new tab) before work begins. The line does not check this for you.
Before you agree to anything, it is worth reading how to choose a pool company and the guide to what pool service costs in Phoenix.
