With regular usage, it can be common for the shower waste outlets to get blocked. Learning how to clear the blockage can give you peace of mind and you wont even have to call plumber Coulsdon again and again. While you are taking a shower and the water is not draining away it is an indication that there is something wrong in inside. Shower waste that might be stuck in the outlet which is not letting the water to pass through. This waste is a collection of strands of hair, dirt and the lather from soaps and shampoos. The first thing that any homeowner would think of doing is to use the cleaning chemicals. Instead of choosing the chemical, here take a look at a simple approach through which you can unblock the waste outlet:There is always an insert in the outlet that is designed to trap the waste before it reaches the pipelines. You can simply remove the insert by twisting or pulling it. Pick up the junk stuck in there and clean the insert. This is going to be gross but it is necessary if you want the drain to start working again. Before replacing the insert, pour in some clean water so see whether it is going inside or not. If the water is still struggling, then it means that the blockage has reached deep within and removing the debris alone is not going to work. You can use a plunger to pull out whats stuck in the drain. You will have to let water in the tray to build up so that you can get the drain submerged. Place the plunger on the outlet and push it downwards and then upwards. You will have to do this more than twice. This again is going to get a bit messy but it will be worth it in the end. You can repeat it unless you see that water has started to flow.If using the plunger does not help, you can use gauge drain cleaning spring. It goes into the waste outlet and you have to turn it to remove the blockage. Continue turning it until you feel the debris. Then you have it pull it out and it will bring out all the waste that was piled up within. Run water to check the flow. If it is going down, it means you have successfully cleared the drain.Even if after using the gauge the drain does not work, simply reach for the plumbers Coulsdon.
