Boiling water should be poured down the drain after one-half cup of table salt. Alternately, you may try combining a cup of baking soda with a cup of vinegar, letting it bubble for 15 minutes, and then pouring boiling water down the drain. Try mixing half a cup of salt and a cup of baking soda, letting it sit for a few hours, and then flushing it with boiling water.
While certain drain problems need plumbing expertise, others can be resolved with the help of drain cleaning services.
Get rid of any standing water. Remove any standing water as soon as possible since it quickly attracts insects, bacteria, and mold. It can be removed so that more water can be added later to flush the drain.
Clear any obvious obstructions and inspect the waste disposal. Put on your rubber gloves and clear the area of garbage, including undesirable hair and food scraps.
