The last box goes out on a Friday morning and the duplex is finally empty. You run the shower to check the water heater, and the tray holds an inch of standing water before it clears. Nine days from now a new lease starts, the painters come Monday, and this vacancy is the only window you get to book the drain cleaning Leander TX landlords usually postpone until a tenant complains. Use it. Clearing and documenting that line while nobody lives in the unit costs a fraction of what the same line costs when it fails three months into a signed lease.
The Shower That Drains At A Crawl
A drain that runs slow is not a drain that is fine. It is a partially blocked one, and the blockage sits either in the branch under the fixture or further down where both units share a main. Hair and soap film build in the first few feet, while grease and root intrusion sit deeper. The National Weather Service Austin/San Antonio recorded 2.76 inches of rain at Austin Bergstrom in July 2026, running 0.60 inches above the 2.16 inch July normal. Saturated ground is when fine roots work toward a joint that has been weeping for years.
Check The Slowest Fixture Before The Paint
Before anyone tapes off a baseboard, run water in every fixture and let it all drain at once. Fill the tub a few inches, pull the stopper, and watch the kitchen sink and the washer standpipe while it empties. The case we see most often in a duplex is not one bad fixture but one shared main that only shows itself under that combined load. Write down which fixture is slowest. Never pour a caustic drain chemical into a line you plan to have snaked, because it can splash back at whoever opens the cleanout.
Photograph The Line Before The New Lease
An empty unit is the only time a camera can go down the main without asking somebody to stay out of the bathroom for an hour. Ask whoever handles your drain cleaning Leander TX work to record the pass and send you the file rather than a verbal summary. Save the video with the turnover date in the filename and note the footage of anything that looked wrong. What I cannot tell you is how many of those slow drains would have limped along another two years on their own. Nobody tracks that, and a plumber who quotes you a number is guessing.
What A Mid Lease Backup Actually Costs
Run the arithmetic on the version where you skip the vacancy visit. Say the main backs up on a Sunday in February with tenants in place: the after-hours call runs $450, two nights in a motel while the bathroom dries comes to $260, replacing the soaked closet flooring is another $600, and three days of credit against a $900 monthly rent line adds $90. That is $1,400, against maybe $425 for a scheduled cleaning and camera pass in a week the unit sat empty anyway. Those numbers are illustrative and yours will differ. The gap between the two columns will not.
Turnover Week Then Versus Turnover Week Now
Ten years ago the only tool for this was a cable. A plumber ran the snake, water moved again, and nobody knew whether the cable had bored a channel through a soft plug or actually cleared the pipe wall. Now a camera rides on most mid-size trucks, hydro jetting scrubs the wall instead of drilling through the middle of a blockage, and you leave with a file for the unit’s folder. A slow drain is a bill with a later due date. The difference now is that you can see the due date coming.
One Scheduled Visit Ends The Turnover Scramble
Nine days is enough for one plumbing visit, and one visit is what this takes. Book it for the day after the keys come back, before the painters take over the unit, and ask for the cleaning and the camera pass on the same trip so nobody bills you twice for the drive. Then put a reminder on the calendar for the next turnover. The next tenant signs on a unit whose main line was looked at, on video, within the last two weeks, and that is worth more than what it added to the turnover bill.
