7 Common Problems with Septic Tanks

Common Problems with Septic Tanks

One of the most disappointing parts of the plumbing system is when our septic tank systems get into some trouble. This is not only because they contain nasty wastes and chemicals but because of the fact that our do-it-yourself skills will no longer work in this situation. This would cause us to engage with plumbing professionals to do the repair for us. Most of the times, these troubles are caused by overusing the system and improper maintenance of the household residents. But it is not a single problem that would probably arise in the system, various problems might trouble you. Listed below are the seven common septic tank problems that would require you to engage with professionals.


Too much water within the tank

   The proper usage of water at home does not only concern the bills you would have to pay if you don’t conserve it, it concerns your septic tanks as well. This is because too much water in the septic tank is dangerous to your system. It can deny the solid waste an amount of time to break down and decompose. The water within the tank would tend to elevate solid wastes in a certain level, and if the water in the tank is too much, it might elevate the wastes that much enough to block and obstruct the pipes and inlets. Even if they are small enough to pass through these pipes and inlets, they are still considered a pollutant and is harmful to the surrounding area of the tank.


Insufficient water on the other hand

   Conserving water is actually helpful to your pockets and to the environment, but when done too much, it is not helpful to the septic tank too. The lack of water within the tank is threatening to the good bacteria within the tank that helps in decomposing the wastes and in neutralising nitrogen within the system. The water helps these bacteria to thrive and when there is no enough water, it can cause the death of the bacteria and would cause sludge and wastes build-up in the tank. Aside from that, the nitrogen can no longer be neutralised that might lead to water contamination.


Non-biodegradable wastes on the system

   Non-biodegradable wastes, since time immemorial, are really not meant to be on our sewage and septic system. They are the major cause of the troubles and predicaments of our system. But sometimes, they can really find their way through the sewers and into the tank. When they are already in the tank, they can elevate the water level and occupy too much space in the tank. When the water level is raised too high, as mentioned above, it can cause the obstruction of the tubes and inlets. This can be avoided by either avoiding any access of foreign objects into your drains and toilets or pumping your septic tank often.



   Most homeowners usually use chemical drain cleaners to clean their drains and these chemical cleaners tend to end up in your septic tanks. In the long run, chemicals like solvents, cleaners, pesticides and thinners could damage your septic tank walls and harm the bacteria inside it. These chemicals can as well leak to the surrounding area of the tank when the walls leak and could be a pollutant and threat to the environment. Chemicals found in your detergents commonly known as phosphate encourages mould growth and could obstruct your inlets.


Fat, oil and grease substances

   The next primary causes of septic tank troubles are fat, oil and grease, commonly known as FOG and are usually drained in the kitchen sinks. They do not easily break down and they might obstruct our inlet pipes and distribution tubes especially due to the fact that they are usually elevated above water molecules. Aside from that, they can as well cause a stench odour that is basically harmful to your family’s health.


Tank Capacity

   When your tank has a lesser capacity, it cannot contain too much waste volume and they would probably overload causing sewage backup that is basically every homeowner’s nightmare. Septic tanks vary in the size and its size is directly proportional to its capacity. If you belong to a bigger household, it would be better to utilise a bigger tank with bigger capacity or you would have to constantly pump your tank.



       It is important that every year, your septic tank should be inspected by a plumbing professional and the amount of sludge within your tank should be measured. This inspection would be able to detect septic tank obscurities like leaks and corrosion so you could hand over early remedies.
