Septic Tank Troubleshooting Checklist

How a septic tank works | By Sam Warren

Are you having problems with your septic tank? Follow our Septic Tank Troubleshooting Checklist to find out what's going on!

If your septic tank has been quietly working away underground for years without bothering you, it can be a bit of a shock when things start to go awry. If you think you might have noticed problems brewing, here's our Septic Tank Troubleshooting Checklist to help you get to the bottom (excuse the pun) of what's going on.

Ok, so what do septic tank troubles look like (or smell like, might be more appropriate)? Trouble underground can show itself above ground in all sorts of unpleasant ways. You might notice your toilets taking longer to flush than usual, or hear gurgling sounds in the pipes. You might notice puddles of dirty water pooling above where the drainage system is, or even waste water spilling out of manhole covers. You may also notice some unpleasant whiffs coming from the system - the odd niff here and there usually isn't anything to be concerned about, but if it's persisting and putting you off your lunch, you'll want to investigate (or stand well back and get someone else to).

  1. Is it time for an empty? This might sound like an obvious starting point, but if you've had family staying over, or anything that might increase the usage of your septic tank, it might be needing an empty sooner than usual. So, first things first, arrange for the septic tank to be emptied. If this sorts the problem out, then I am glad to have been of service!
  2. Check what's been flushed into the system. Septic tanks and other off mains drainage systems can be sensitive things, and there are plenty of things that could be flushed into them which would cause them all sorts of upset. Things such as antibacterial cleaning products, grease and oil and even cotton buds can wreak havoc with your septic tank (especially if you also have a soakaway system). Read our full article here on the top ten things you shouldn't flush into a septic tank. If anyone in your household has flushed something down there that they shouldn't have, this might have caused a blockage.
  3. Check that the covers for your septic tank and any other manholes are in tact - any breaks or splits can let surface water into the tank, which might cause it to overflow.
  4. Is any part of your drainage system outside of the boundary of your property? This isn't unusual in the world of off mains drainage systems. If so, you'll want to go and check whether anything's happened in the area that the system is - for example vehicle movement above soakaway pipework, which can cause the pipes to collapse.
  5. Check where you think the problem might be occurring. If you've spotted water pooling above the ground where your soakaway system is, it might mean that the soakaway has stopped working properly, and waste water is making its way to the surface instead of passing through the sub soils. Has there been any movement in the ground around the tank itself? This might indicate damage to the walls of the tank itself.
