Why Your Drains Keep Clogging (and How Hydro Jetting Helps)
By The Rialto Plumbing Pros Team · October 10, 2025 · 6 min read
A drain that clogs repeatedly is telling you the cause was never removed. Here's how to find it — and when hydro jetting is the answer.
Clearing a clog feels like a fix, but if the same drain backs up again in a few weeks, the real cause is still in the pipe. Recurring clogs point to something that a quick snake-out didn't remove — and identifying it is the difference between a permanent solution and paying twice.
Common causes of recurring clogs
- Grease and soap buildup narrowing the pipe over time (common in kitchen lines)
- Hard-water scale accumulating on pipe walls
- Tree roots entering clay laterals through cracks and joints
- A partially collapsed, bellied, or offset section that catches debris
- A venting problem causing slow, gurgling drainage
Why a camera inspection comes first
For repeated clogs or multiple affected fixtures, a video camera inspection shows exactly what's happening inside the pipe — buildup, roots, breaks, or offsets — and where. A camera inspection runs $145–$390 locally, and it turns guesswork into a targeted plan. It also tells you whether a clog is a maintenance issue or a repair issue.
How hydro jetting helps
Hydro jetting uses high-pressure water to scour grease, scale, and roots from the pipe walls — a far more thorough clean than a cable snake, which often just punches a hole through the blockage. Jetting runs $290–$780 locally.
But it isn't for every line. Fragile, collapsed, or severely damaged pipe can't safely handle the pressure, which is why a technician should assess pipe condition first. On a suitable line, jetting restores full diameter and buys you far longer between problems.
Preventing the next clog
Keep grease out of kitchen drains, use strainers, and avoid pouring repeated chemical products down the line — they can damage pipes and rarely solve the underlying cause. If roots are the issue, ask about a maintenance jetting schedule or a permanent repair to the entry point.
Snaking vs. jetting: what each actually does
A cable snake punches a hole through a blockage and restores flow fast — good for a hair clog or a single stoppage. Hydro jetting scours the full diameter of the pipe with high-pressure water, removing the grease, scale, and root film a snake leaves behind. That's why jetting buys far longer between problems on a recurring line — but only when the pipe is sound. On fragile or collapsed pipe we won't jet; we camera-inspect and recommend the repair instead.
A plumber's take: the clue is which drains are slow
Where the slowness shows up tells us a lot. One slow fixture usually means a local clog. Several fixtures slowing together, gurgling toilets, or backups at the lowest drain point to the shared line — a sewer issue, not a sink issue. Matching the symptom to the right pipe is how we avoid clearing the wrong drain and charging you twice.
A five-minute monthly drain routine
A little monthly attention keeps most drains flowing and catches trouble early. Once a month, fill each sink and tub, then release it all at once — a full column of water flushes the line better than a trickle and tells you which drains are slowing. Pull and clean pop-up stoppers and shower strainers of the hair and gunk that collect there. In the kitchen, run plenty of cold water before, during, and after the disposal, and never send grease or fibrous scraps down. Skip the caustic chemical cleaners; they punish pipes and rarely fix the cause. If a drain slows despite the routine, that's your early signal to get it looked at before it becomes a full backup.
The bottom line
A drain that clogs again didn't get fixed — the cause is still in the pipe. Skip the repeat chemical pours, get a camera inspection for anything recurring, and jet the line when it's suitable. We solve the cause so you stop calling about the same drain.
Kitchen vs. bathroom clogs: different causes, different fixes
Where a drain clogs shapes the right fix. Kitchen lines clog from grease and food that cool, harden, and narrow the pipe — hydro jetting restores full diameter, and keeping grease out prevents the repeat. Bathroom drains clog from hair and soap scum binding in the trap and branch line, usually cleared mechanically, with a hair catcher as prevention. Main-line clogs that affect several fixtures at once are a different animal entirely — that's the sewer lateral, and it needs a camera inspection, not a plunger. Matching the fix to the location is how you stop paying for the wrong repair.
