The best way to prevent your drains from blocking up is to be very careful about what you put down them. Oil and grease are a big no no! Even just a little bit everyday adds up.
- Collect waste cooking oil and grease in portable containers with lids and throw them in the bin.
- Wipe greasy pans and plates with paper towel before washing them and throw the paper towel in the bin.
- Once a week, fill each sink and tub in your home to the brim and then pull up the plug. The volume and weight of the water will fill the drainpipe completely with water. It will do a good job of flushing the drain line.
- If your drain is running slowly or smells, pour a pot of boiling water down it. That will clear a lot of problem clogs, especially in your kitchen drain, where oils are likely to collect and solidify.
- Check sinks and plugs every 3 months or so for hair and soap scum (biofilm) buildup and give them a quick clean by pouring a quarter of a cup of baking soda down the drain, followed by half a cup of vinegar. Wait ten minutes for that to do its thing, then flush it with boiling water.
If you have ongoing problem get a professional out to give you a permanent solution.
