Take a look at what is happening inside
When you take a look inside your drain and begin to ask yourself questions like ‘Should there be water in my outside drain?’. Then we have got a problem. If the chamber is holding water instead of draining it away, then you can conclude that somewhere after the drain chamber is clogged. Usually, a clogged soil pipe is the cause, but other things can also cause a blockage. But, there’s just one way to be certain. Search for a full chamber on a side and an empty chamber on the other side and when you find it that is the location of your blockage.
At this point we might be able to help without contacting a drainage company and costing hundreds of pounds, we can use the below to options to help unblock your drain so why not try these first
Use Drain Rod
Manually using a drain rod is perhaps the best way to clear blocked drains. It is a useful outside drain unblocker tool that you can easily purchase in local stores or online. After locating the blocked chamber (which is where your blockage is), thrust the drain rods into this chamber until the blockage is removed. When pushing the drain rod, rotate it clockwise because this helps to dislodge the blockage properly. Nevertheless, try not to turn it anticlockwise because the plunger attachment may be unscrewed. Repeated thrusting of the rods will loosen the blockage and cause it to dislodge.
Use a self Propelled Jet wash
A great way to clear a blockage without using chemicals is to use a hose or pressure jet to force the obstruction through the pipe. To do this, you should first clear the drain as much as possible using your hands or tools and then scoop out the water to a manageable level.
You will then want to push your garden hose or pressure jet as far down the drain as possible and then begin sealing the drain cover entrance. You should do this by firmly packing the entrance with old towels or sheets to stop the pressure you’re building up from simply causing the drain to overflow.
Blocking one avenue of water egress will help the pressure rise and force through the blockage, although you should make sure to pack it tightly with material so that it doesn’t just get pushed out. This also has the added advantage of avoiding splashback that can cover both yourself and your home with stagnant water.
After turning the hose or pressure jet on high for around 10 seconds, the blockage should have cleared. If it hasn’t cleared in that time then it is unlikely that this method will work.
