Fixing a Slow Tub Drain

For slow drains in old houses, pour a bottle of bleach down the tub drain once a month in the evening (every 5 weeks for the bathroom sink). In the morning, heat up a tea kettle and pour one gallon of water down the drain. Aim for the drain (or use a funnel), so as not to crack porcelain. This works only on slow drains.

Bleach and your septic system is a delicate balance. The good bacteria break down the "sludge" and make your system work properly. I don't know the science et, but do know what my septic cleaner guy told me. Bleach used very sparingly, no garbage disposal use, no fats down the sink. Also have your system cleaned/pumped every few years. The baking soda and vinegar trick work well for me. Good luck.

So sorry but, besides what's already been mentioned about environmental issues, bleach is a highly corrosive chemical and sitting/standing in older plumbing pipes will greatly shorten the life of those pipes and the fumes emitting from it is horrible for the lungs and eyes. :-(

I agree with other posters. Bleach is a terrible idea, very toxic to the water system. And a whole bottle! A better way is 1 cup of baking soda followed by 1 cup vinegar or 1 cup boiling water. To get all the baking soda down the drain, push it along with a bit extra vinegar or water.

Do not put bleach down your drain or toilet even if it is only once a month. where I work we clean with bleach and would put bleach in toilet and the sanitation person came to do their inspection and told me that we should not do this. It can hurt the septic tank. She said just do it once in a while not everyday or once a month.

The only down side to this tip is for people who has septic tank instead of public sewage, the bleach can kill the good bacteria. :-(

I don't see any reason for using the bleach, that would not unclog the drain. It is the hot water that is doing the work. Soda and vinegar would work and would be better for the environment than bleach.

Tip: Fixing a Slow Drain

My tub drains slowly (the only one in the house that does). I am sure there isn't a clog. I have an enamel tub, so I removed the plate, and when I gently pulled it out there wasn't a chain. I don't know if it a plunger type or a ball. Do I have to remove the tub, or is there a way to take out the drain plate from the tub so I can see into the drain?

Sometimes when a bath tub drain is slow, there is an accumulation of hair and crud in the drain between the tub and the trap. Trap cleaners rarely clear these obstructions. There is a tool available at most home stores that is just right for this job and it only costs a couple of dollars. Find a Zip It, they work great!

Good luck. Rygobus

RE: Fixing a Slow Drain

I use vinegar and baking soda every week to keep my drains running smoothly and odor free. Dump baking soda down the drain, then pour vinegar in after. The acidity of the vinegar and the bubbling action will help keep drains clear. (07/01/2010)

Also, have you tried the salt and boiling water? There was a post this past week, too, by a man that puts coffee grounds down his drain and never has slow drains, search that out on this site for more details. Good luck! (07/02/2010)

RE: Fixing a Slow Drain

Try using boiling water, I mean water boiled in a pot or teakettle, not just very hot from the faucet. This should help dissolve whatever is clogging the drain. As you may have to do it several times, while waiting for the next container of water to boil you could use the vinegar/baking soda combination. (07/11/2010)

How can I clean out my bath tub drain? I've pulled out a clog of hair, but it still doesn't drain properly. I don't want to have to hire a plumber. I've also poured hot water down it and a drain cleaner. It's still slow.

RE: Fixing a Slow Drain

Because you already used commercial drain cleaner, wear rubber gloves and goggles for safety. While running water into tub, use the toilet plunger (this will bring up a lot of yuk from the drain. Wipe this up with paper towels. Don't allow it to go back down the drain. Plunge until you achieve results.

Then add 1/2 cup baking soda and 1 cup white vinegar. Let stand approximately 30 minutes. Pour in a quart of boiling water, then run cold water to rinse clear. Repeat if necessary. Remember to use baking soda, vinegar, and boiling water every month or two, and you will never buy Liquid Plumber again! (02/16/2010)

RE: Fixing a Slow Drain

Pour baking soda into the drain until it's coating the upper drain. Pour vinegar over the drain and allow the bubble action and then chase it down with hot water. The drain will open up and you water will flow freely again in the drain.

If this doesn't help unclog the drain, then you may have a more serious problem, but try it a couple of times and see if that helps. I use this method each month to keep drains clean and the water running freely. (10/03/2009)

When our bathtub drain slowed up, my husband used the toilet plunger on it. Gross, but worked. This was after using Drano and boiling water a bunch of times. (10/01/2008)

RE: Fixing a Slow Drain

What I do is to take the out the drain stopper, an easy process, pull out the gunk with needle nose pliers and replace the drain stopper. Much easier than taking the time to pouring stuff down the drain and not have it work. (10/01/2008)

Get a bent piece of wire and fish the hair out of the drain, it is usually near the top of the drain. You'd be surprised how much hair can accumulate there. (10/01/2008)

I recently read here on ThriftyFun that a plumber recommended pouring a bottle of "Nair" or another depilatory type hair remover (for women's legs) down the drain and leaving it sit for several hours because hair is usually the main culprit. You may have to do it twice. (10/04/2008)

RE: Fixing a Slow Drain

Hi Beth! None of the tips posted on the link above worked for me last time I had this problem, so I bought a product at Menard's called Instant Power Hair and Grease Dissolver. It comes in a tall black plastic bottle, inside of a clear plastic bag, like a baggie. I poured about 2 cups of it into my (bath) drain, and by the next morning the drain was completely clear! I also realized what was causing my problem, it was the body wash I had been using, one of the "cream" types. It was good for my skin, but awful for my drain! Made it greasy and a trap for hair and dirt. You might want to give it a try. :) (05/02/2008)

By Kayray

RE: Fixing a Slow Drain

The Menard's fix sounds interesting. I never use chemical products that might harm the drain. I use my garden hose to clear all drains. It even works on the toilet unless there is an unusually tight clog. Simply hook the hose to a faucet (I try to hook it to my basement stationary tub faucet so I get hot water which is more effective). Use one of nozzles on the hose that is the skinny type if you have one, and push it down the drain as far as possible, then pack wash cloths or rags all around to keep the water from coming back into the basin or tub that is slow. Have a friend turn the water on full force while you hold the nozzle into the drain. Let the water run for several minutes...at least 5. The drain should clear, but if not, I'd try it again only longer. It helps to do this process at the wall of a sink and sometimes you will discover the clog is in the trap (curved pipe) under the sink and can easily be cleaned out by hand, eliminating the need to use the hose.

Put some baking soda followed by vinegar in the drain on a regular schedule. Maybe once a month helps keep it running smooth. (05/03/2008)

RE: Fixing a Slow Drain

Hi. I frequently use the method of pouring baking soda in the drain and then vinegar. However, I do heat my vinegar in the microwave before pouring it in on top of the baking soda. But stand back, because it really steams up. You can hear the gurgling, then I run hot water afterwords and watch the little whirlpool because the water runs so much faster. (05/05/2008)
