Keeping a Leon Valley septic system healthy
A septic tank in Leon Valley only needs a few things from you. Pump it on a schedule, keep heavy vehicles off the drain field, and send only water and waste down the drains. Grease, wipes and harsh chemicals shorten the life of the tank and the field. A quick yearly look at the lids and the ground above the field catches small problems early.
When to call a septic company
Call when drains slow down throughout the house, pipes gurgle, sewage smells appear indoors or in the yard, or the ground over the tank or drain field turns soggy or unusually green. A backup in the lowest drain in the house needs attention the same day. If you are buying or selling a home in Leon Valley, schedule an inspection early so there is time to act on what it finds.
Finding the right local company
Local experience matters with septic work, because soil, rules and common system types change from county to county. A company that works around Leon Valley and Balcones Heights, San Antonio, Castle Hills will know what the Bexar County health department requires and what tends to go wrong on local properties. Ask for references on bigger jobs and keep every invoice with your home records.
