After the storm, not every backup is your pipe

Hill Country rain does not fall politely. It hits caliche, jumps a creek, and fills a sanitary system that was already carrying Saturday laundry. In San Antonio a backup after a storm can be a house clog that finally closed, a belly that filled, or a municipal surcharge that would have happened even if your line was perfect.

If manholes in the street are talking, wait. Running a cable into a surcharged city system is how people pay for a visit that could not have succeeded. Watch city channels for official notices. Then look at your cleanout. If the cleanout is dry and the house is wet, that is a different story.

A house line that was 80 percent closed by grease or roots has no spare capacity when the ditch is full. The storm did not “cause” the grease. It revealed it. That is a useful, unsentimental sentence.

Do not shower to “see if it is better.” Do not run the washer because the power came back. Every gallon has to go somewhere. If the somewhere is your tub, you just volunteered.

Camera work after the water falls is how you stop guessing. Roots, offset clay, and a crushed hub look different from a grease plug. The repair conversation depends on that picture. See sewer line.

Lots near San Antonio Missions National Historical Park have mature trees and older laterals. North-side PVC still bellies where fill settled. The storm does not care about the decade the house was built.

Sewage in the house is an emergency for health and finishes. Use emergency plumber. Keep people off the wet floor. Fans after the water is gone, not during.

Insurance language is not something a blog should invent. We can describe what we saw. We cannot promise how a policy reads. We also will not fabricate a review about a storm we did not attend at your address.

If you are in Schertz or Boerne, your utility owner may not be San Antonio. Use the city page that matches the driveway. The hub map on the home page stays on San Antonio for a reason.

When you write the request, say whether the street was flooding and whether more than one fixture failed. Those two facts prevent a lot of wrong first tools.

Cleanout caps that were left off “to relieve pressure” become mosquito hotels and trip hazards. If someone told you to leave it off during a surge, ask when it goes back on. A missing cap after the water falls is how debris enters the line you just cleared.

Floor drains in garages and utility rooms are the canaries. If they burp first, believe them. Running a shower to “test” after a burp is how a canary becomes a pond. Wait, look at the street, then test one fixture if the outdoor cleanout is quiet.

Lots with pecans and clay laterals should expect roots to enjoy a wet week. That is not a moral failing of the tree. It is a reason to camera after the system falls instead of declaring the house innocent because the storm was dramatic.

Sandbags and plywood belong to flood prep. They do not clear a lateral. Do not block a cleanout with storm gear. The next person may need that cap more than you need a place to stack bags.

If the backup started before the rain, the storm is not the villain. It is the amplifier. Write the timeline. “It was slow on Tuesday and exploded Thursday night” is a useful sentence. “The storm did it” is a feeling.

Hill Country rain does not wait for you to finish a load of laundry. If the washer is mid-cycle and the floor drain talks, stop the machine. Every extra gallon has to live somewhere. Tonight that somewhere might be the hall bath.
