Slow drains, gurgling toilets or a shower that backs up when the washing machine drains are signs of a deeper blockage. CPI Plumbing, Heating, Cooling & Electrical provides drain cleaning and hydro jetting for homes throughout Mount Vernon, WA. We clear the clog and clean the pipe, so the problem doesn’t come right back a few weeks later.
Every home and every clog is different. That’s why our plumbers start by finding out what’s causing the blockage and where it’s located. From there, we recommend the cleaning method that will solve the problem for the long term.
Drain Cleaning in Mount Vernon, WA
Not every clog needs hydro jetting. For a single slow sink, tub or toilet, our plumbers start with professional drain cleaning using cable machines sized for the line. This clears hair, soap scum, food waste and other common blockages quickly and safely.
When clogs keep returning, or several fixtures back up at the same time, the problem is usually further down in the main sewer line. In those cases, snaking alone often isn’t enough. That’s where hydro jetting comes in.
What Is Hydro Jetting?
Hydro jetting is like pressure washing for your pipes. A specialized nozzle at the end of a high-pressure hose sends water through the line in every direction. As it moves through the pipe, it scours away grease, sludge, scale and tree roots from the full width of the pipe walls.
A drain snake only punches a hole through a clog, leaving buildup behind that can catch new debris. Hydro jetting removes that buildup completely, restoring the pipe close to its original diameter. It uses only water, with no harsh chemicals going into your plumbing.
When Is Hydro Jetting Needed?
- Recurring clogs: Drains back up again a few weeks after snaking, a sign that buildup is still lining the pipe.
- Multiple slow drains: Several fixtures drain slowly at the same time, pointing to a problem in the main sewer line.
- Tree roots: Roots from the large trees common in Mount Vernon yards have worked their way into the sewer line.
- Grease buildup: Kitchen lines are coated with fats, oils and food waste that harden over time.
- Older pipes: Cast iron and clay lines in older Mount Vernon homes collect scale and debris that narrow the pipe.
Benefits of Hydro Jetting
- A thorough clean: Removes buildup from the full width of the pipe, not just the center of the clog
- Longer-lasting results: Clean pipe walls give new debris less to catch on, so clogs return less often
- Chemical-free: Uses only water, so there are no harsh drain cleaners in your plumbing
- Root removal: Cuts and flushes out roots that have worked into the sewer line
- Versatile: Works on kitchen lines, bathroom drains and main sewer lines
Our Hydro Jetting Process
- Camera inspection: We run a sewer video inspection to find the blockage and confirm the pipe is in good enough condition for jetting.
- Hydro jetting: We clean the line from the access point to the main, adjusting water pressure to the pipe material and condition.
- Follow-up inspection: A second camera pass confirms the line is clear and flags any cracks, offsets or root entry points that need repair.
If the camera finds a damaged or collapsed section, we’ll show you the footage and explain your options, including trenchless sewer repair.
