Pool Repair for Southwest Houston's Older and Rebuilt Lots

When new equipment meets old plumbing

On lots first developed in the postwar decades, the equipment pad tends to be a patchwork. A pool that old has rarely kept its original pump or filter, so a recent motor can sit beside a filter from another decade, fed by suction and return lines older than both. On rebuilt lots the pool may be new, or an existing shell may have been kept and tied into new gear.

Patchwork pads fail in ways a single part does not explain. A new pump that pushes harder can open a tired glue joint that held for years at lower pressure. A heater's flow switch may never close while a variable-speed pump idles at its lowest setting, so the heater looks dead when the real problem is flow. An automation panel added later may be driving valve actuators older than the panel. That is why the whole loop gets checked, not only the piece that stopped. The component pages go deeper: pump repair, filter repair, heater repair and automation.

Pads that have been underwater along Brays Bayou

Brays Bayou cuts through Sharpstown, Meyerland and Braeswood Place, and its floods are part of the repair history on many of these streets. A yard-level pad in Meyerland could have gone under in 2015, again in 2016 and again in Harvey in 2017. Braeswood Place has its own record, with about 500 homes flooded in Tropical Storm Allison in 2001.

Flood damage tends to arrive late. Fine bayou silt can stay packed inside a heater or a valve body, and corrosion keeps working on wiring and circuit boards long after the water drops. The first sign might show up a year or more later as a motor that runs hot, a display that blanks out on humid days, or a GFCI that trips after a rain.

If your equipment has flooded, tell us which storm and roughly how high the water rose. That steers the diagnosis and helps decide whether a repair on previously submerged gear is money well spent. If floodwater got into the pool itself, storm clean-up comes before any repair.

Clay, big trees and water that disappears

Southwest Houston sits on the Beaumont Formation. A presentation at a University of Houston geotechnical conference rated about a quarter of its clays moderate to high in shrink and swell potential, about half high, and most of the rest very high. Pool plumbing runs through that clay to the skimmers, main drain and returns, and on an older pool a joint that shifts a little each season for decades can eventually open.

Trees add to the stress. The same presentation found that trees, mainly live oaks, or their removal were the main cause of foundation distress at most of the sites its author investigated, most of them commercial buildings. A large oak dries the clay around it, and taking one out lets that clay rewet and swell. Neither proves your plumbing is affected. But water loss that began the season a big tree came out, bubbles collecting in the pump lid, or a fresh gap between deck and coping is worth tracing before anything gets dug up.

Useful to know before a repair visit

• Roughly when the house and the pool were built, if you know
• Whether the equipment pad has ever flooded, and in which storm
• The horsepower and speed type printed on the pump motor's label
• Any large tree planted, lost or removed near the pool
• Whether the water level drops faster with the pump running or off
