Ennis Pool Service & Repair
Ennis draws its water from a single source, Lake Bardwell, and the city publishes current chemistry on that supply every year. That is a real advantage for a pool owner, because what comes out of the fill hose sets the starting point for balance, scale control, and sanitizer demand. A&M Pool Service & Repair has serviced Ellis County pools since 2006, from our family-owned shop in Waxahachie about 13 miles west, and our routes reach from neighborhoods near the Texas Motorplex to homes closer to the lake. Weekly cleaning and equipment repair both start from $140, and we work on the brands common to local backyards.

What Lake Bardwell Water Does to Your Pool
Ennis runs on surface water from Lake Bardwell under PWS 0700001, treated with chloramine. The 2024 report puts total hardness at 116 ppm and TDS at 193 ppm, which is soft to moderate by Texas standards. Soft fill water behaves differently from the hard well and blended supplies in much of the region. It is less likely to drive heavy calcium scale on salt cell plates and heater elements, and that changes how we set your saturation target and how often a salt system needs descaling.
The disinfectant is the part worth watching. Ennis chloraminates, with a measured residual of 3.17 ppm and a pH of 7.91 in the published data. Chloramine is combined chlorine, so every top-off or drain-and-fill adds combined chlorine to your water along with the volume you wanted. That can read oddly on a DPD test, where free and combined numbers do not line up the way you expect, and it can raise chlorine demand for a day or two until the pool burns through it. We account for that when we test after a fill instead of chasing a reading that the fill water itself caused.
The rest of the panel rounds out the picture: calcium at 42.6 ppm, total alkalinity at 101 ppm, magnesium at 2.29 ppm, sodium at 20.6 ppm, chloride at 24.3 ppm, and sulfate at 27.0 ppm. Alkalinity near 100 gives your pH something to hold against, which is useful on a chloraminated supply where pH tends to climb. We use these published values as a baseline and then test your actual pool water, since evaporation, swimmers, and chemicals you have already added all move the numbers off the source.
Ennis sits on Blackland Prairie clay, the Houston Black soils that run 60 to 80 percent clay. That ground swells after rain and shrinks in a dry August, and it pulls on whatever sits in it. Decks heave, coping shifts, mastic joints open, and underground plumbing takes strain over the seasons. We watch the expansion joint and the bond beam during regular visits, because a crack that gets caught early is a repair and one that gets ignored becomes a leak.
Common pool service calls in Ennis
- Chloramine spikes after a fill. After a big top-off or a drain-and-fill from city water, combined chlorine climbs and your DPD test looks off. We test and correct on the next visit rather than overdose the pool.
- Salt cell scaling. Even on softer Lake Bardwell water, salt cells build calcium over time and lose output. We inspect and descale on a schedule so the chlorine generator keeps up through summer.
- Freeze damage on the equipment pad. Ellis County still gets hard freezes, and the February 2021 storm cracked pumps and pipes across the region in days. We check freeze protection and winterize pads before the first cold snap.
- Clay movement around the deck. Wet-dry clay cycles open mastic joints and crack coping. We flag movement early and reseal joints to keep water out of the soil under your shell.

What Ennis Customers Say
"First company that actually explained what was wrong with our heater instead of just quoting a replacement. Fixed it for a fraction of what the other guys wanted to charge."
Pool Service FAQ — Ennis
The 2024 city report lists total hardness at 116 ppm and TDS at 193 ppm, which is soft to moderate. That means lighter scale pressure on salt cells and heaters than the harder supplies elsewhere in the county.
Ennis uses chloramine, which is combined chlorine. A fresh fill adds combined chlorine to your pool, so a DPD test can show numbers that do not match until the pool works through it. We test after the fill settles.
Yes. Our Ennis routes reach homes across the city, including the Lake Bardwell recreation side and neighborhoods near the Texas Motorplex.
