Sewer cleanout installation for Houston houses

Most backups we see start in the main line, somewhere between the house and the city tap. A two-way cleanout set a few feet out from the foundation lets us run a cable or jetting hose downstream toward the street, or back upstream toward the house, from one spot. That matters when the clog is roots near the property line or grease packed under the kitchen. We dig to the line, cut out a short section, install a two-way fitting with two risers and set both caps flush with the soil or inside a small box so the mower clears them. Once it is in, clearing a main line clog usually starts in the yard instead of your bathroom.

An existing cleanout only helps if the cap comes off. Brass plugs seize inside old cast iron, plastic caps crack under a mower wheel, and some risers snap off below the grass. A missing or broken cap also lets rainwater, dirt and roots into the sewer and lets sewer gas out into the yard. When the cap is the only problem, we cut the riser clean and fit a new threaded adapter and plug. If the riser has cracked down where it joins the main, we dig it out and replace the riser and fitting together, so the new cap has solid pipe to thread into.

Some lines leave no room in the yard, such as a main that runs straight under a driveway or a patio poured tight against the house. Then a cleanout right at the foundation wall is often the practical answer. It sits where the drain leaves the slab, so it also catches clogs that start inside before they reach the yard. We check the depth and fall first, because a line that exits shallow or at an odd angle may need a different fitting. If the camera shows a sag or break right at that spot, the job becomes a sewer line repair with the cleanout added as part of it.
