Drain Cleaning FAQ
What do plumbers recommend to unclog drains?
There are two separate answers here: what we recommend you try before calling anyone, and what comes off the truck when you do. They are different tools for different stages of the same problem.
Short answer
For a homeowner, most plumbers will tell you to try three things in order: a proper plunger, a barbed zip tool for hair, and pulling the P-trap under the sink. Those three cover the large majority of single-fixture clogs and none of them can damage your plumbing. For prevention, we recommend a monthly bacterial enzyme treatment rather than anything caustic. What we recommend against is store-bought chemical cleaner, especially more than once on the same drain. If a drain is slow again within days, or more than one fixture is affected, stop treating the symptom. That pattern means the restriction is further down the line, and the answer is a cable machine or a jetter, not another bottle.
The Three Tools We Tell Homeowners to Own
A drain auger is not one of them, which surprises people. The three we recommend are a plunger of the correct type, a barbed plastic zip tool, and a pair of hands willing to open a P-trap. Between them they clear most clogs that originate at or near the fixture, and crucially, none of them can damage your plumbing if used wrongly. That matters more than effectiveness. A homeowner with a powered auger and no training can score a pipe wall, punch through a weakened cast iron line, or leave a cable wrapped around an obstruction where it cannot be retrieved.
For prevention we point people at bacterial enzyme treatments rather than anything caustic. Used monthly overnight, they digest the soap and grease film before it has a chance to build into a blockage. They will not rescue a drain that has already stopped, and anyone selling them that way is overselling.
When We Tell People to Stop and Call
Three patterns mean the problem is past the point where home methods help, and recognising them early saves money:
- It comes back within days. A drain that clears and re-blocks has an accumulation still in the pipe. Something cut a channel through it; nothing removed it.
- More than one fixture is affected. A toilet that gurgles when the washer drains, or a tub that backs up when the toilet flushes, means the restriction is in the main line. Work at the sink cannot reach it. Our sewer line repair team handles these with a camera first.
- Standing water that will not budge. Nothing you pour in will reach the blockage through a full basin, and if what you pour is caustic, you have made the eventual repair hazardous.
In Fort Collins there is a local version of the first pattern worth flagging. Hard water deposits scale on the inside of drain lines, and scale is a debris trap, so the interval between clogs shortens year on year. That slow narrowing is not something a homeowner can address, and it is one of the more common reasons we recommend hydro jetting over cabling on a kitchen line that keeps coming back.
What Changes in an Older House
Advice that is fine for a 2005 build is not always fine for a 1955 one. Homes in Old Town, Andersonville and Midtown frequently still run original cast iron or clay drain lines, and both change the calculus. Cast iron corrodes from the inside, leaving a rough interior that catches debris far more readily than smooth PVC, so clogs recur faster and respond less well to chemistry. Clay laterals joint with mortar, and tree roots find those joints reliably.
In those houses we are more cautious about repeat chemical treatments and quicker to recommend a camera inspection, because the question is no longer only “what is blocking it” but “is the pipe still sound”. If you are seeing rust-coloured water or recurring blockages in an older property, the related reading on ageing supply and drain pipe is worth a look, and our Old Town service page covers what we see in that neighbourhood specifically.
What do plumbers use instead of Drano?
In the truck, nothing in the Drano category exists. For a stopped-up sink or tub we use a small drum machine with a quarter-inch or three-eighths cable and a cutting head sized to the pipe. For a main line we use a larger sectional or drum machine, and for grease and mineral scale a hydro jetter. For maintenance between visits we leave customers with a bacterial enzyme product. The reason is not brand loyalty, it is that caustic chemistry cannot remove a hair mat, cut a tree root, or scour scale off a pipe wall, which is what most real blockages are made of. Mechanical tools take the obstruction out of the pipe instead of melting a hole through the middle of it.
For homeowners we suggest the same substitution in miniature: a zip tool instead of a bottle for hair, a plunger instead of a bottle for a sink, and an enzyme product instead of a bottle for maintenance. If you have already poured something caustic and the drain is still blocked, tell whoever comes out. It changes how we open the trap, and it is a straightforward safety matter rather than a judgement.
How do plumbers clean out drains?
Professional drain cleaning is usually one of three tools, picked after we know what the clog is. A cable machine, often called a snake or auger, feeds a rotating steel cable down the line with a cutter head on the end to break up or retrieve the blockage. A hydro jetter pushes water through a reverse-thrust nozzle at high pressure to scour the pipe walls back to bare material, which is what clears grease and mineral scale rather than just punching through them. A drain camera goes in on a flexible cable so we can see whether we are looking at grease, roots, a foreign object, a sagging section or a cracked pipe. On a recurring problem the camera comes first, because it decides which of the other two is appropriate.
Which of the three we lead with depends on what the drain has been doing. A first-time single-fixture clog gets cabled, because it is fast and usually sufficient. A recurring kitchen line or a house with hard-water scale gets the camera and then usually the jetter, because cabling a scaled pipe clears the channel and leaves the walls coated. A main line in an older neighbourhood always gets the camera first. You can see the full scope of equipment and what each is for on our drain cleaning and sewer camera service page.

We scope before we quote. A camera inspection shows whether you have grease, mineral scale, tree roots, a sagging section or a cracked pipe, and that is what decides between cabling, jetting and a repair.
