Pulling a hair mat out of the shower drain

Nearly every shower hair clog sits in the first arm’s length of pipe, which is why a barbed plastic strip beats a bottle of drain chemical. Here are the tools that pull a hair mat out whole, and the signs that the problem is deeper than hair.

Pulling a hair mat out of the shower drain

A shower hair clog is nearly always within arm’s reach. Hair collects at the strainer and just below it, binds with soap and shampoo residue into a mat, and sits in the top few inches of the drain body or in the trap immediately under the pan. That means the tool that works is one that grabs and pulls: a barbed plastic strip, a pair of long needle-nose pliers, or a small hand-crank drum auger if the mat has slid further down. A plunger and a bottle of chemical are the two things most people reach for first, and they are the two least likely to shift it.

Get the cover off first

You cannot pull what you cannot see, and the cover is where most people give up. There are five common types and each opens differently.

A screw-in strainer has a visible screw in the centre; back it out with a Phillips driver and lift the plate straight up.

A snap-in or press-fit cover has no fastener at all and comes up with a flat blade prised gently under the rim.

A lift-and-turn stopper in a tub lifts, then unscrews from its post once you hold the base and turn the knob.

A toe-touch stopper unscrews from the top in the open position, sometimes leaving a shaft that also unscrews.

A trip-lever tub drain has no stopper in the opening at all; the mechanism comes out through the overflow plate with two screws, and it drags a surprising amount of hair with it.

Take the extra minute here. Screws in a shower drain corrode into the crossbars, and a driver that is slightly too small rounds the head and turns a ten-minute job into a drain body replacement. If the screw will not move, a drop of penetrating oil and ten minutes of patience beat force.

The tools that actually pull hair

A barbed plastic strip removes most of these clogs; feed it in, turn it a half turn, and draw it out slowly so the mat comes up whole instead of tearing.

Long needle-nose pliers reach the mat sitting on the crossbars of the drain body, which is where a good deal of it collects.

Hemostats or locking forceps grip wet hair better than pliers do and are far easier to work one-handed.

A hand-crank drum auger with a quarter-inch cable reaches through the trap when the mat has gone past the strainer; feed it, turn it, and withdraw it slowly rather than shoving hard.

A wet and dry vacuum, with the pan wetted so the hose seals against it, will sometimes lift a loose mat that a strip cannot grip.

A torch and a small mirror, so you can look before committing to a tool, which is the step almost everybody skips.

Two things matter more than which tool you own. Pull slowly, because a mat that comes out in one piece brings the soap film with it while a mat that tears leaves half of itself behind on the crossbars. And work upward rather than pushing down: anything you drive past the trap is now somewhere the same tool cannot reach.

Why the plunger disappoints here

A plunger works by moving a column of water, and it needs a sealed system to do it. A shower has a shallow pan, a wide flat opening and no water depth to speak of, so most of the push escapes around the cup. In a tub there is an overflow opening a few inches up the wall that has to be held shut with a wet cloth or the pressure vents straight out of it. Even done properly, plunging pushes against a mat anchored to the crossbars. It compresses and springs back.

The bottle under the sink

Caustic openers do partly attack hair, since keratin is a protein, but they work slowly, they sit in the trap if they fail to clear it, and they heat the pipe wall. On old cast iron and on plastic joints neither of those is welcome. Enzyme treatments are gentler and useful as a habit on a drain that is still moving, though they will not remove a mat that is there today, and there is a separate article on this site about what those products can and cannot digest. Whatever is under the sink, never mix two of them.

When it is not hair

If you have pulled a clean mat out and the shower still drains slowly, the restriction is further along. Slab-on-grade construction is the norm in Costa Mesa, and a shower on a slab drains into pipe running under the concrete, so none of that section can be judged by eye. In housing of the 1960s and 1970s, and the median Costa Mesa home dates from 1972, that pipe is usually cast iron. Cast iron does not so much clog as close: the inside face corrodes into a rough scale that keeps catching whatever passes over it.

This is why the same shower can back up a few weeks after being cleared. A cable bores a passage through the soft material and leaves the scale it passed through exactly as it was. High pressure water, or in the worst cases a replacement section, is what deals with the wall itself. That decision should follow a camera in the line, not a guess made from the bathroom floor.

If the toilet is involved, stop

A shower that floods when the toilet is flushed is not a hair problem at all. Those two fixtures share a branch and then the main line, and water arriving in the pan from somewhere else means the blockage is downstream of both. Stop running water and go and look at the outside cleanout. The separate article here on main line signs walks through what to check and in what order.

Keeping the mat from rebuilding

A hair catcher sitting over the drain, emptied every week, keeps almost all of it out of the pipe.

Rinse the pan with hot water after a haircut or after anyone with long hair has washed it, so loose hair goes through rather than settling.

Pull the strainer and clear the crossbars monthly, which takes a minute and stops a mat ever forming.

Deal with a slow drain while it is merely slow, since a mat that has been building for a year is much harder to bring out whole.

If the mat you pull out is grey and greasy rather than clean hair, that is soap and mineral binding it together, and the same coating continues further down the pipe than your strip can reach.
