5 signs of a blocked sewer & what to do about it

You slept through your alarm and you’re running half an hour late.  You quickly jump out of bed, grab something to eat, run to the bathroom only to be confronted with a toilet bowl full of water once you flush……. not good!

The scenario above is a pretty gross and annoying event that should be avoided if possible.

To help you out a bit we’ve listed 5 early warning signs of a blocked sewer that you can look out for.


1// Toilet bowl fills with water and sometimes gurgles after flushing

As we have mentioned in a scenario at the start of this blog post, this is a very common problem that we are all bound to experience.  Don’t just shrug your shoulders and expect the problem to go away.  This is a definite sign that you have a blockage in your sewer and you should call a plumber to sort it out before the situation becomes worse.

If you own a restaurant or provide facilities to your customers, this is definitely something you want to get on top of straight away.

2// Strange noises

Can you hear a strange noise coming from your sewer pipes? Listen out for these noises through your toilets, bathtubs, sinks and showers. If you can hear strange noises, it doesn’t mean that your house is haunted.  It’s more than likely a sign that there is something wrong with your sewer.

3// Trees look good in your garden but they can cause damage

Look around your house and see if there are any big trees near the sewer pipes. Why? Believe it or not, tree roots have a way of getting into and crushing sewer pipes and blocking your sewer.

4// What’s that bad smell?

5// Water is slow to drain

Have you ever tried to drain something and it takes longer than usual to empty out? You guessed it – slow draining is another early warning sign that your sewer is blocked.  While you may be able to clear it temporarily using a plunger you will ultimately have to deal with the problem as most of the time it will keep occurring.

From the first phone call Curran plumbing services were professional, showed up on time for scheduled quote , then me updated when the job was going to be completed . On the day of install all of the staff were well trained , well spoken and installed my new instantaneous gas hot water system like they were installing it in their own home . The quality in detail to make sure I was satisfied didn’t go unnoticed. At the end of the day I feel like I have gained a plumber for life . 100% recommend.
