What are we called for most in Colleyville?
Our Colleyville calls come down to two kinds of jobs: heaters, and pumps and filters.
-
Heaters. When the weather turns, the calls sound like this: the heater clicks and never lights, lights and quits after a minute, or runs for hours while the water stays cold. Before opening the cabinet, we read the error code, confirm gas is reaching the unit, and check water flow. Details are on our pool heater repair page.
-
Pumps and filters. The rest is circulation: a pump that won't hold prime, a noisy motor, or a filter gauge that stays high after cleaning. A heater needs steady flow, so a tired pump or packed filter often shows up first as a heater error.
-
Weekly pool service is available in Colleyville too, but repair is where we spend most of our time here.
Is your pump or filter the real problem?
Often, yes. If you notice any of these, the heater may be fine and circulation needs attention:
-
The heater shows a flow or pressure-switch error.
-
Return jets push noticeably less water than they used to.
-
The pump basket fills with air, or the pump runs dry after a restart.
-
The motor squeals, rattles or hums without starting, or water collects under it.
-
Filter pressure won't come down after cleaning, or climbs again within days.
For pumps, we choose between a capacitor or seal, a new motor, or a complete pump (often Hayward or Pentair), and explain how a variable-speed model would run on your system. For filters, we clean, service and repair cartridge and DE units. More on pool pump repair and pool filter repair.
How do you get pool equipment ready for winter in Colleyville?
Make sure the pump runs when it freezes. A working freeze guard starts the pump automatically near freezing so water keeps moving through pipes and equipment. During extreme cold, Atmos Energy asks customers not to use pool heaters and to run the pump during the coldest part of the day (Atmos Energy winter tips, checked on November 11, 2026). Before the first hard freeze, we can test the freeze sensor, pump, timer and heater.

What should Colleyville pool owners know?
These facts come from official City of Colleyville documents:
-
Your water comes from Lake Arlington. Colleyville buys its water from the Trinity River Authority's Tarrant County Water Project, which draws mainly from Lake Arlington.
-
It is moderately hard. Total hardness was 119 ppm as calcium carbonate (about 7 grains per gallon) and alkalinity 101 ppm (sampled February 27, 2023). If calcium and pH drift high, that water scales the tile line and heater heat exchangers. Source for 1 and 2: City of Colleyville 2023 Consumer Confidence Report.
-
Backwash goes to the sanitary sewer. Under Ordinance O-02-1358, pools permitted on or after November 1, 2002 must send filter backwash to the sanitary sewer through city-approved means, never to a street, storm drain, creek or lake.
-
Every pool must be fenced. Colleyville's Land Development Code requires a fence or barrier at least 4 feet high, gates that close and latch on their own with the latch in the upper quarter of the gate, and pool entrances that lock with a key or combination. Source for 3 and 4: Colleyville Residential Swimming Pool and Spa Maintenance overview.
-
New codes since April 2025. Under Ordinance O-25-2317, Colleyville adopted the 2024 International Codes, including the Swimming Pool and Spa Code, effective April 1, 2025. If an equipment change involves new gas or electrical work, ask Building Inspections (817-503-1031) about permits. Sources: Colleyville adopted codes and Ordinance O-25-2317.

Why won't my pool heater light or heat?
Most heater failures trace back to gas supply, ignition, water flow, controls, or scale inside the heat exchanger.
Safety first: if you smell gas near the heater, don't light it or flip switches. Leave the area and, from a safe distance, call 911 and your gas company's emergency line. Atmos Energy's is 866-322-8667. Source: Atmos Energy winter safety, Sources last checked November 2026.
Clicks but never lights: we check the igniter, gas valve, gas pressure, and debris or insects in the burner tray.
Lights, then shuts off: we check the pressure switch, high-limit switch and flame sensor, and whether low water flow is tripping it.
Runs, but the water stays cold: we check the thermostat setting, the bypass valve, and calcium scale on the heat exchanger.
Blank display or error code: we check the control board, wiring and transformer, and whether the timer or automation is calling for heat.
Heat pump runs but heats weakly: we check the air temperature (heat pumps lose output in cold air) and the airflow around the unit.
Repair or replace? We weigh the heat exchanger's condition, the unit's age, parts availability, and whether the fault keeps returning. A failed igniter or switch on a sound heater is usually worth fixing; a corroded or badly scaled heat exchanger on an older unit often isn't.
What we don't do
We don't offer leak detection, plastering, resurfacing, tile, new pool construction, pool removal, restoration or commercial work. For those, please contact a specialist.

Colleyville pool repair FAQ
-
Do you repair gas pool heaters and heat pumps in Colleyville? Yes. We diagnose and repair both, and we install a new heater when repairing the old one no longer makes sense.
-
Why does my heater turn on and then shut off? The most common reason is low water flow from a dirty filter, a struggling pump or a closed valve, which trips the pressure switch. A faulty high-limit switch or flame sensor can do the same, so we test each one.
-
Is it worth repairing an older heater, or should I replace it? It depends on the heat exchanger, parts availability and whether the fault keeps coming back. We show you both options before any work starts.
-
Do you repair Hayward and Pentair pumps in Colleyville? Yes. Hayward and Pentair are the pumps we work on most, from capacitors and seals to complete replacements.
-
Do you offer weekly pool service in Colleyville too? Yes, weekly service is available in Colleyville, though most of our work here is heater, pump and filter repair.
