How to Unblock a Blocked Toilet - Guaranteed!! Using Just a Mop and a Bag

Unblocking A Toilet How To Unblock A

A blocked toilet can seem like an emergency job requiring a plumber to remove the blockage... but do not panic, as it is a task which is often easy to fix by using our FREE yet simple method. In the first instance we are going to try a mop and a sturdy plastic bag. As you can see from the many comments we've had, it seems that many people have had success with blocked toilets using our 'super sized plunger' which is made simply from an old mop with a plastic bag tied around the head. Make sure the bag is sturdy and won't tear too easily. This seems to be a sure fire way to shift the stubborn blockages that other plungers just can't deal with. Best of all it's FREE!!

So, if you're stuck, before calling a plumber, give it a go. And please leave us a comment at the bottom of the page if it works (or not). Recent comments include:

  • "Amazing! I had a horribly blocked toilet for two days and tried everything. I was about to call a plumber when I found this web page. This method worked so quickly, I couldn't believe it. It saved me the cost and embarrassment of calling a plumber. Thank you!"

  • "Worked so well it made me laugh. Spent 2 days using various chemicals, flushing, hot water and all other methods. Finally decided 2 buy a mop and it worked in about 5 seconds. Awesome tip"

  • "Fabulous method! Fixed the problem in less than a minute! So glad I came across this page. Feel like a domestic goddess now!"

  • "How ironic that I look online for just about everything but never ONCE thought to look online when the (newly installed!!) toilet decided to act up on a Bank Holiday weekend! I didn't have cable ties but I "double bagged" the plastic bags, twisted 2 handles together (to make one sturdier one), wrapped the handles around the stick and tied really tight. Got a little nervous when it didn't work on the first go buy, as they say, if at first you don't succeed...Thank you...Thank You...THANK YOU!!!"

Our Step By Step Guide...
Step 1. Get a good sized mop and sturdy plasic bag. It's better if it won't rip.
Step 2. Attach the bag firmly to the mop. Cable ties work well.
Step 3. Force the mop down the toilet. Once may well do it. If not then try repeatedly.
Step 4. Admire your unblocked toilet...
Or The Conventional Way
To unblock a blocked toilet conventionally rather than using the mop and bag method, here are the Essential Tools you will need:
  • Plunger
  • Rubber Gloves
  • Goggles
  • Bucket
  • Clearing Rods
  • Auger

What Causes a Blockage?

Unfortunately, toilets occasionally do get blocked, usually due to too much toilet paper or heavy loads being put down the pan. First things first, you need to find the location of the blockage. If you have drain inspection covers outside, it is worth lifting the one nearest the pan. If the chamber is full, you need to try to clear the blockage in the pipes or around the drain either using a specialist rod or a makeshift device, such as a wire or piece of wood. If the Drain Is Unblocked, the blockage must be located somewhere between the chamber and the pan. In most cases, the blockage is found at the pan itself.

Unblocking the Pan
Following these simple steps should fix most blockages:
  • Try pushing a flexible drain cleaning wire down the WC pan.
  • It is a good idea to ask someone to observe the drain chamber while you are doing this to see if the item causing the blockage emerges. Anything emerging that may have caused the blockage should be removed. If you don’t remove an offending item, you only run the risk of it causing a blockage further down the system which may be more difficult to unblock.
  • It’s worth using a plunger or auger (see below) if you have one.
  • A chemical drain cleaner or caustic soda may help, but you must follow the instructions carefully and remember these products need to be handled safely. Always use rubber gloves.
Plunger Basics
Try using a plunger to unblock the damage. Most people have a cup shaped plunger but this does not always work and can be a bit messy. Toilets bowls benefit from a specialist flange shaped or a ball shaped plunger. Both these types of plunger have a bottom which is shaped to seal the opening in the bottom of the toilet bowl. This seal action as you plunge creates the necessary vacuum and pressure and is more effective.

Toilet Auger
A toilet or WC auger, available from most hardware stores, is a special plumbing tool used to clear blocked toilets. This device uses a flexible clearing rod with a hand crank, a long sleeve handle and a special auger device at the end which is used to break blockages or retrieve them. The auger drops into the toilet as far as possible. It reaches about 0.5 metres. The auger is connected via the flexible shaft to the crank handle which you control. When the obstruction is discovered you clamp and turn the cranked handle and either push or pull the blockage to dislodge it. Once the blockage is removed flush and clean your loo and disinfect the auger.

More Top Tips
Another useful tip is to consider draining water from your toilet pan. If the water level in the pan of your WC is high, you should consider this. Try using any old container to bale out the water first or you can use a hose to siphon it off. You can also try pouring hot or boiling water down the pan as an alternative to using caustic soda. Often this can be helpful and will break down clogged up matter down your waste pipe.

Great tip as good as the one about ironing out watermarks on tables it worked first time after 2 hours of messing about with all the usual

After 2 days of having a completely blocked and unusable toilet and as a last ditch attempt after trying literally EVERYTHING to unblock it, I thought I would have a go at this before calling out a plumber. Didn't for one minute think it would work to be honest but worth a try if it meant saving 100 quid. It worked after the first attempt!I have never been so happy! Thank you to whoever published this you absolute gem!!!!

Thanks you, thank you, thank you. Just spent all morning trying different methods of clearing a blockage. No joy. Found this page, one push of the mop and all is good. Cannot thank you enough for saving me the drama and cost of calling a plumber.

absolutely fabulous many thanks for a great plumbing tip. this gives me a story to tell in the pub later.
paul - 5-Apr-19 @ 10:47 AM
A big round of applause for this awesome little site!!! Love the images too!! Yep this defo truely does work! I just came across this site randomly, but tried this method a while back now (minus the bag and partly in frustration!) and it worked a treat - The only prob was that the end of the Vieleda mop detatched and got sucked down the toilet when it unblocked the offending blockage!! :O Only £3.50 for a new one in Tesco, so pretty minor. The toilet blocked again recently and I thought I would invest in a plunger, but it is useless in comparison. I selotaped the head on this time before giving the mop another whirl and it unblocked it without the head coming offthis time. Didn't think to use a plastic bag as suggested here, but that would work just as well and potentially keep the mop a bit less contaminated!!!! Happly blockage free flushing everyone!!
Damo - 4-Apr-19 @ 9:58 PM
Thank you so much! Had a blocked toilet, tried the chemicals, baking soda and vinegar, the coat hanger trick, anything you can without the tools like a snake or plunger. Ready to call the plumber and i stumble across this page and the mop technique, first go and it unblocked it! I can't thank whoever made this website enough!
MalcolmG - 29-Mar-19 @ 12:22 PM
Thank you!! I had stuck on rubber gloves and couldn't find the blockage. Then I tried this trick and it worked in seconds!
Mrs D - 17-Mar-19 @ 2:53 AM

Sarah - 10-Mar-19 @ 8:17 AM
Spent days trying to unblock my toilet. I have 2 men so you can guess that the load my toilet takes is more than usual! I was at my wits end when I found this method! Instantly unlocked and no mess or having to get my hands near the state of the toilet!! Amazing!
Klem - 24-Feb-19 @ 9:58 AM
So my toilet was blocked with GOD ONLY KNOWS and had been playing up for a couple of weeks... i tried this and within about 10 secs of "plunging" i risked lifting it up and VOILA! Water had gone. This trick is AMAZING and i will tell everyone i know
Flick - 10-Feb-19 @ 10:36 PM
Been trying on and off to clear a partial blockagein our downstairs loo, without success! THE MOP AND BAG plus plenty of water 5 minutes, hooray.
the brain - 8-Feb-19 @ 3:31 PM
The best thing I've used is a 2ltr empty plastic pop bottle leave the cap on and cut across the bottom of the bottle to take this part away then rubber glove up put the bottle in the toilet bowl get someone to flush the loo and hold the bottle with two hands around the top of the bottle and push down and up like crazy to suck the water into the bottle to create a vacuum into the bowl and it works like a plunger you may need to do two or three times but it sure does work.make sure you put the bottle into a bag after to stop drips etc.

@Dazza - yeh it's not for the drains further down the line. But this article is just for blocked toilets not blocked drains.
BNB - 13-Sep-18 @ 10:56 AM
Unless the blocked area is near to the front, then it does not work at all.
Dazza - 12-Sep-18 @ 3:23 PM
Thank you so very very much. It actually works. Yes I did use a red bag and have a lovely red colour at base, but a bit of bleach and this will gol. Im so grateful . Just been waiting for a delayed plunger to be delivered and you have solved it. Thanks
dizzy di - 30-Aug-18 @ 8:22 PM
worked a treat, used a blue Gap bag with string drawstring, and in hindsight I should have turned it inside out, as I now have a blue stain on the toilet bowl!Otherwise, I was very impressed!

Gayle - Your Question:
I managed to unblock 3 toilets at work using this tip, it's brilliant and so simple.I used a big Tesco carrier bag and just held onto the handles around the mop, I gave it a few pushes and it flushed away, then I just dropped the bag into the bin, and best of all NO SPLASH BACK.I usually have at least one toilet blocked every week, and I certainly won't be going back to using a loo brush, great idea THANKS.

Our Response:
We are glad this has managed to solve your ongoing blockage problem to minimal effect!

I am a cleaner in a mens warehouse, and the toilets are always disgusting. I have 3 toilets blocked at the moment and have used 5 toilet brushes, which wasn't a good idea, what with only having disposable hand gloves, it wasn't enough to cover my arms from the splash back.... Needless to say the length of a mop handle sounds like a great idea, I'm going to try out the mop and carrier bag tomorrow, thanks for the tip, I think I might need quite a few bags !!
