Who repairs pool pumps and filters in Southlake?
We do. Equipment repair is the main reason Southlake homeowners call us, and pumps and filters top that list. We work on residential pools only, mostly Hayward and Pentair equipment. Our team has more than 20 years of combined experience, and we are rated 5.0 starts in Google reviews (read them on Google).
If you are comparing companies, ask what they look at besides the part that failed. We test the pump, filter, heater, valves and timer or automation together. A new pump pushing water through a clogged filter will not last.
What are we called for most in Southlake?
Three jobs make up most of our Southlake visits: pumps and filters, heaters, and green pools.
Pool pumps are essential for circulation and filtration. We can inspect pumps experiencing reduced flow, unusual noise, leaks, or operating problems.
A dirty, damaged, or poorly functioning filter can affect water flow and filtration. We provide cartridge and DE filter cleaning, service, and repair.
We provide residential pool heater repair and installation, including system inspection and evaluation of existing pool equipment.
Three jobs make up most of our Southlake visits: pumps and filters, heaters, and green pools.
-
Pumps and filters. Most calls start with "the pump is humming but nothing's moving," "it's loud," or "the filter pressure keeps climbing." We check the motor, capacitor, impeller, shaft seal, lid O-ring and the suction side before we name a cause. On the filter, we compare the pressure reading with its clean reading and open it up to inspect cartridges, grids or sand. Details on pool pump repair and pool filter repair.
-
Heaters. A heater that clicks, lights and shuts off, or won't fire at all is often reacting to low water flow, not a failed heater. That's why we look at the pump and filter first.
-
Green pools. Green water usually means chlorine ran out while filtration was weak or stopped. We clear the water and fix whatever let it turn.

What are the signs your pump or filter needs repair or replacement?
Call for a check if you notice any of these:
-
The pump hums but won't start, or trips the breaker.
-
Grinding or screeching from the motor (often worn bearings).
-
Air bubbles in the pump basket, or the pump keeps losing prime.
-
Water dripping under the pump at the seal.
-
Filter pressure 8–10 psi above its clean reading, even after cleaning.
-
Sand or DE blowing back into the pool, or a cracked filter tank or clamp.
-
Weak return flow or a skimmer that barely pulls.
Should you repair or replace? How we decide
We decide based on the whole pad, not one part. A single failed capacitor or seal on a healthy motor is usually worth repairing. A motor with worn bearings, a cracked housing, or parts that are hard to get often isn't. For older single-speed pumps, we explain how a variable-speed pump would run on your system so you can choose. Either way, you hear the options and our recommendation before we touch anything.
Heater not heating, or water turning green?
-
Heater problems: we check flow, the pressure switch, ignition and the heat exchanger. Hard water can leave calcium scale inside the exchanger over time (see the local water facts below). More on pool heater repair.
-
Green water: we brush, balance and treat the pool, and then find the cause: a pump that stopped, a filter that is overdue for cleaning, or run time that is too short. If you want help keeping it clear, weekly service is available. See Pool Maintenance Services.

These facts come from official Southlake and Fort Worth sources:
-
Your water comes from Fort Worth. Southlake buys all of its water from the City of Fort Worth, which draws on six surface sources, including Eagle Mountain Lake and Richland-Chambers Reservoir. Source: City of Southlake 2023 Water Quality Report.
-
It is moderately hard. Fort Worth reports a total hardness of 79.9–134 ppm as calcium carbonate (about 5–8 grains per gallon). That's enough to build scale at the waterline and in heaters if calcium and pH drift. Source: Fort Worth drinking water report.
-
Backwash goes to the sanitary sewer. Southlake's pool guidelines say backwash lines must drain into a P-trap connected to the sanitary sewer. Chlorinated or salt water may not go into a storm sewer, creek, bar ditch or onto another property. A cartridge filter avoids backwashing altogether. Source: Southlake Pool Guidelines, Feb 2026.
-
Draining has its own rules. Before draining to your sewer cleanout, call Southlake Public Works (817-748-8082). Lower chlorine below 3 ppm and keep the flow at or under 50 gallons per minute. To drain onto your lawn, chlorine must be below 0.1 ppm and pH between 6 and 8. Source: City of Southlake, "How to Drain Your Pool Safely".
-
Pool barriers and gates. The barrier must be at least 48 inches above grade on the outside. Gates must open outward, away from the pool, and an outside-release latch must sit at least 54 inches high. Any fence that forms part of a pool barrier needs a city permit. Sources: Southlake Pool Guidelines and When is a permit required?
