Notes on Austin pools

Notes from Sullivan's Pool Service on keeping a pool in Austin — the things we end up explaining on the phone often enough to write down. All of it is specific to this city rather than to pools in general: the fill water here is hard enough to scale a heater, the ground moves under half the metro, and an Austin summer does things to chlorine that a generic guide will not prepare you for.

    Keeping an Austin pool alive through the summer

    An Austin summer changes three things about your pool at once: water temperature climbs past 90°F, which roughly doubles chlorine demand; evaporation runs at an inch or more a day, which concentrates calcium and stabilizer; and bather load peaks. Almost every summer pool problem in this city traces back to one of those three, and the fixes are unglamorous.

    Five things that go wrong with spas, and what they mean

    Most spa problems are volume problems wearing a disguise. A spa holds a fraction of a pool’s water at twenty degrees warmer, so every bather, every hour of heat and every dose of chemical has an outsized effect. Cloudy water, a failure to heat, foaming, a chlorine smell and weak jets are the five we get called about most, and four of them are usually the same underlying cause.

    Which pool upgrades are actually worth the money

    On an Austin pool, one upgrade pays for itself and the rest are comfort purchases. A variable-speed pump is the one: power draw falls roughly with the cube of speed, so running long and slow moves the same water for a fraction of the electricity, and Austin pools run long hours. Everything else — salt, automation, lighting, heating — is worth buying for what it does, not for what it saves.
