How Pool Helpline works in the San Antonio area

We're a video service, not a local pool company, and we don't have an office in the San Antonio area. You book a call, point your phone at the equipment pad (pump, filter, heater, salt cell and any display codes) and a real pool tech guides you by voice. Many problems can be diagnosed, and often fixed, in one call. If yours needs hands-on work, we'll help you find a local pro.

Flat prices, shown before you book: Quick Fix $49 · Full Diagnostic $89 · Priority Fix $139.

Power outage or a tripped breaker?

When the pump and the rest of the equipment go quiet in the San Antonio area, first work out whether it's the pool or the grid. If the neighbors and streetlights are out too, it's an outage: report it to your utility (links above). If everyone else has power, the problem is on your side, usually a tripped breaker or GFCI for the pool equipment. Reset it once. If it trips again, leave it off and call a licensed electrician (see pool light or electrical problem).

Anyone in the water who feels tingling, or a pool light flickering or on when it shouldn't be, is an emergency sign, not a repair to try: the U.S. Consumer Product Safety Commission says to get out of the water, turn off all power, and call 911 if someone may have been shocked. During an outage, SRP suggests turning off appliances so there's no surge when power returns; when it does, check that the pump primes and that the timer or automation clock didn't reset (see pump not priming).

Summer heat: pumps, heat and algae

San Antonio's summers are long and getting hotter. The National Weather Service office for Austin and San Antonio notes the city's all-time record high of 108°F on August 19, 1986, and in 2022 San Antonio tied its July record of 107°F and had its record warmest May, June and July, with exceptional drought lasting into 2023.

Hot water and long pump hours are hard on a pool. Algae can take hold quickly, so the CDC's home pool targets matter: a pH of 7.0 to 7.8 with at least 1 ppm free chlorine (at least 2 ppm with stabilized chlorine such as trichlor tablets). If the water turns cloudy or green, or the filter pressure climbs (see filter pressure high), a tech can walk you through it by video. A water level that keeps dropping faster than you'd expect could be a leak rather than evaporation (see pool losing water).

When a hard freeze hits

Freezes are uncommon here, but they happen. During the February 2021 winter storm, the National Weather Service says San Antonio International Airport stayed below freezing for 4 days and 12 hours, one hour short of the record from 1951, and problems with the Texas power grid left hundreds of thousands without power in the cold. A pool pump that can't run in that kind of cold can't protect the plumbing.

Pentair's IntelliFlo3 pump guide says that in mild climates, when temporary freezing conditions may occur, you should run your filtering equipment all night, and warns not to rely on the pump's own freeze-protection "Thermal Mode" alone to protect the whole system. If the power goes out during a freeze, report it to CPS Energy (above), and before you restart, look for cracked pump housings, filters or pipes, or have a pool tech look by video (see pump humming but not starting).

San Antonio pool barrier rules

The City of San Antonio's Development Services Department follows the 2024 International Swimming Pool and Spa Code with city amendments. Its permit bulletin (IB 170) says a residential pool needs a barrier at least 48 inches high, measured on the side away from the pool, with no more than 2 inches of clearance at the bottom over grass or gravel and no opening a 4-inch sphere can pass through. Gates must open outward away from the pool and be self-closing and self-latching, and house doors that open onto the pool area need an audible alarm or another approved protection. Cities around San Antonio set their own rules, so check with yours before changing a fence.

San Antonio pool not working? Start here

• Pump not priming: Pump runs but the basket won't fill. Almost always air or water level.
• Heater won't fire: No heat, a flow or pressure code, or an ignition lockout. Flow comes first.
• Salt cell / chlorinator codes: No Flow, Check Salt, Inspect Cell and what the IntelliChlor LEDs mean.
• Green pool water: Green means chlorine ran out. Find out why so it doesn't come back.
• Electrical safety & pool lights: Tingling, flickering lights or a GFCI that won't reset. Treat it as an emergency.
• Need a replacement part? Send us your model and the old part's label, and a tech matches the exact part.
• Need someone on site? Tell us your ZIP code and we'll help you find a local pro.
