  "description_short": "A built-in gauge lets you dial the pressure from 0 to 8 bar, and four interchangeable heads seal against toilets, sinks, baths and floor drains so the blast goes down the pipe instead of back at you.",
  "description": "The problem with a slow drain\n\nNobody thinks about drains until the water stops going down. Then it becomes the only thing in the house that matters. You get the sink filling while you rinse a plate, the shower tray ankle deep by the time you are done, or the toilet rising instead of falling after a flush.\n\nMost of these blockages are not dramatic. There is rarely a lost toy or a brick in the pipe. What you usually have is a soft plug of hair, soap scum, cooking fat, coffee grounds and bits of food that has built up over months. The pipe narrows a little at a time until one day there is not enough space left for the water.\n\nThat matters because it changes what works. A rubber plunger pushes water one way, then pulls it back. On a soft blockage, that often just packs the material tighter against the pipe wall. You feel like you are making progress because the water moves a bit, then it stops again an hour later.\n\nHow air pressure clears a pipe\n\nAn air pressure drain cleaner pump takes a different route. You pump air into a sealed chamber until the gauge reads the pressure you want. Then you seat the head over the drain and release everything in one burst.\n\nThe pulse travels down the pipe and hits the blockage from one side with real force. Because the burst is instant rather than gradual, it tends to break the plug apart instead of compressing it. The water sitting in the trap carries the energy along, which is why these tools work better when there is some water in the system.\n\nThe whole thing takes seconds. Pump, seal, fire, check. If the water drains away, you are finished. If it does not, you add a bit more pressure and go again.\n\nWhy the gauge matters more than the maximum\n\nPlenty of air drain tools advertise a big headline pressure figure. This one reaches up to 120 PSI, which is plenty. But the number that actually changes how you use it is the gauge on the body, which reads from 0 to 8 bar.\n\nWithout a gauge you are working blind. You pump until your arms say stop and then fire whatever you happened to build. On a kitchen waste pipe that is a bad habit, because those pipes are narrower and the joints are not designed for much shock.\n\nWith the gauge you can match the force to the fixture. The supplier recommends roughly 1 to 2 bar for sinks and kitchen sinks, 3 to 4 bar for toilets, 5 to 6 bar for floor drains and sewer pipes, and 7 to 8 bar only when the situation genuinely calls for it. Treat those as starting points, not targets. The best air pressure plunger technique is to begin lower than you think you need and step up one notch at a time.\n\nGetting the seal right\n\nThis is where most people go wrong on the first attempt, and it has nothing to do with pressure.\n\nAir follows the easiest path. If there is any gap between the head and the drain surround, the burst escapes sideways into the room instead of down the pipe. You get a loud noise, a wet floor and a drain that is still blocked.\n\nFour heads come with the pump, each shaped for a different opening. Pick the one that sits flattest against your fixture, not the biggest one. Press down firmly with both hands before you release. On a bath or basin, cover the overflow with a wet cloth, because that opening is a direct escape route for the pressure.\n\nA little water around the rim helps the seal grab. If you are working on a toilet, make sure there is water in the bowl. On a dry floor gully, pour a jug in first.\n\nWhich drains it suits\n\nThe four heads cover the usual list. Toilets, bathtubs, kitchen sinks, wash basins and floor drains are all within range. For a typical house that is every drain you have.\n\nIt is a good fit if you want the best sink unblocker that does not involve pouring caustic chemicals down the pipe, or if you are on a septic tank and do not want to kill the bacteria doing the work. Only air and the water already in the system go into the pipe.\n\nIt is also worth having if you rent out property or manage a holiday let, where a blocked toilet on a Sunday evening is an expensive phone call. The tool pays for itself the first time you avoid a call-out.\n\nWhere it is less suited is deep structural problems. If a pipe has collapsed, if roots have grown in from outside, or if the blockage sits thirty metres down a shared line, no handheld tool will reach it. Signs of that include several fixtures backing up at once, gurgling from a drain you are not using, or a smell outside near an inspection chamber. Call someone with a camera at that point.\n\nUsing it without making a mess\n\nWear gloves and old clothes the first couple of times. Lay a towel around the base of the fixture. Stand slightly to one side as you release rather than directly over the opening.\n\nWork in stages. Fire once at a low setting, then look. If the water level drops at all, that is progress and another shot at the same setting will often finish it. If nothing at all happened, check your seal before you reach for more pressure, because nine times out of ten the seal is the issue.\n\nRun hot water down the pipe afterwards for a minute or two. That flushes the broken-up debris further along so it does not settle again a few inches down.\n\nFor hair in a shower or bath, it helps to pull out what you can reach with a hook first. The pump then only has to deal with what is deeper in the pipe.\n\nLooking after it\n\nRinse the body and the head you used under clean water, then dry everything before it goes back in the cupboard. Make sure no pressure is left in the chamber when you store it.\n\nThe one part worth checking is the sealing ring. If you pump and the gauge does not climb, the ring has almost certainly slipped out of its groove. Open the pump, reseat the ring all the way round so it lies flat, and close it again. That fixes the problem in nearly every case.\n\nStore it somewhere dry and out of strong sun. Rubber and sunlight are a poor combination over the long run.\n\nAt 900 g and just under 34 cm long, it fits in the cupboard under the sink alongside the cleaning bottles. Keeping it where the problem happens means you actually use it.\n\nThe short version\n\nA plunger works by moving water back and forth. This works by storing air and releasing it in one hit, which is far better at breaking up the soft, matted blockages that cause most household drain trouble.\n\nThe gauge is the feature that makes it sensible for everyday use. Set 1 to 2 bar for sinks, 3 to 4 for toilets, 5 to 6 for floor drains, and keep the top of the range for the jobs that really need it. Four heads cover every drain in a normal house, and nothing needs charging or plugging in.\n\nGet the seal right, start low, and work up. Most blockages give way long before you reach the maximum.",
