My cat just peed on my curtains!

Cat Pee 2

Here’s how to remove a urine smell for good!

It happens: dogs, cats (even humans) sometimes pee where they shouldn’t. This often occurs during winter when your animal is reluctant to go outdoors. After all, why suffer the cold and rain when you can back-up and spray inside a nice warm lounge?

Sannitree Odour Digestor has been around for years and it is the go-to product for stubborn animal and urine smell (s) (in fact any organic smell: spilt milk, vomit, smelly shoes . . . rotten fish, you name it)

The old-fashioned approach to removing bad odours caused by urine etc. is to drown them in chemicals and deodoriser. Unfortunately this method does not work and the smell always returns. The reason for this is that the chemicals kill the very microbial bacteria which will eliminate the problem if only you would let them.

Quite simply, the odour (say sour milk) is caused by bacteria feasting on the milk solids. As the bacteria eat they release a gas. This gas is in fact the bad odour which you smell. Unfortunately, these bacteria take quite a while to work – months in some cases – and nobody can tolerate a bad malodour for that length of time. This causes frustrated home owners to resort to chemicals which will of course kill the bacteria, but won’t destroy the milk solids. In time, new bacteria will thrive and the smell will return.

So the cycle goes.

The Sannitree approach to odour removal combines modern technology with ancient natural processes. Instead of killing the friendly bacteria we help them. By giving them an over-supply of enzymes we assist them in breaking organic solids down into bite sized chunks which they can then quickly devour.

The interesting thing about this approach is that the urine smell or other bad odour actually gets worse for a 24 hour period as the microbes embark on a feeding frenzy – but then the odour magically vanishes after the bacteria run out of food. No more food means no more gas, which means no more bad smell.

And the bacteria? Unfortunately, good guys always finish last and it does not end well for them. They literally starve to death and your home is left clean and odour free.

Septic Tank Cleaning & Treatment: Chemical vs Enzymes

What is the buzz with chemicals and septic tanks – are they compatible?

In moderation they are acceptable. After all, you cannot be expected to tolerate bacteria in your toilet bowl and good hygiene is imperative in the home.But watch out for overkill – no need to saturate the toilet bowl with germ killer – so use it sparingly.

And most importantly, NEVER rinse bleach or caustics down your septic system as it will wipe out the entire microbial colony living peacefully inside your tank. Without those friendly microbial’s your effluent will not get broken down, and those killer chemicals will keep your poo in a suspended state of animation. Your tank will fill up too quickly, and before you know it, you will be forking out big bucks to have it pumped.

So what should you do when it comes to septic tank cleaning?

Rather adopt a basic maintenance program whereby you supplement the bacteria which is lost through general cleaning. By flushing Sannitree Bio-Enzymes down your toilet bowl every month you will keep the microbial colony alive and actually speed up the decomposition process that makes your tank tick.

Once those hungry Bio-Enzyme Granules reach the effluent layer inside your tank they begin to salivate and whip out their napkins and cutlery. It is like a buffet for them and they literally feast their way through the poo.

Another way to look at it is to see your septic tank as a mini eco-system. A healthy tank will show signs of life. Expect to see earthworms, small insects and perhaps a hobbit or two making their way through middle earth. Now imagine showering the poor creatures with acid rain in the form of harmful chemicals – this is why we recommend using disinfectants in moderation.

One last thing. If you own a pit toilet it is especially important to keep it biologically active. The knee-jerk reaction to dealing with a bad pit toilet smell is to toss down a bucket of sheep dip. This may kill the smell for about 24 hours, but it will return with a vengeance. Rather give the entire a toilet a good hose down. Add 100 grams of Sannitree Bio-Enzymes with copious water and if you can, give the effluent a stir with an old stick. This will puncture any gas pockets that typically form about a foot below the surface. The entire effluent layer will drop a couple of feet, giving you extra capacity – plus the smell will go away.

Help, my septic tank is blocked up!

If your septic tank is blocked up, keep reading because we can probably save you quite a bit of cash.

A septic system is easy to understand, and once you identify the cause of the blockage you can implement the correct cure. (Using Sannitree Bio-Enzymes will of course reduce the incidents of blockages, but it helps to keep in the know.)

The good news is that there are only three possible reasons for your system clogging up:

1. It’s a simple paper blockage in the septic tank pipe

Firstly, if you are lucky, the pipe system leading to your tank could have a simple paper blockage. Follow the toilet exit pipe as it makes its way to the tank. Lift the first lid of the tank and have a squizz inside (yes, things could get smelly down there, but think of the plumbing costs you are saving). You should be able to see the top of a T-Piece pipe which carries the effluent (that’s a fancy name for poo) into the first compartment of the tank. Is it overflowing? If yes, get a stick and have a poke around inside the T-Piece. If it is a simple blockage it will loosen the paper up and your system will flow again. Alternatively, give it a jet of water from your hosepipe (and don’t throw the stick over your neighbours wall).

2. The tank is full of effluent

If things have not improved then you need to consider the second possibility: your tank is full of sh*t. On average, a tank will need to be pumped every 6 years – even if it is being treated with Sannitree Bio-Enzymes. The reason is that as the effluent is broken down it forms sludge on the bottom of your tank. This sludge cannot be broken down any further and needs to be mechanically removed by a suction truck. Ouch! This will cost a few bucks, but at least you have saved on calling a plumber out to tell you something you can figure out for yourself. To see whether your septic tank needs a pump-out, simply lift the second manhole and peer inside. If you can see bits of paper and poo, then call the pump-out people – those solids belong in the first compartment only.

3. The soakaway has packed up

If no signs of effluent are visible, then it means that your soakaway has packed up, and it can get expensive. Tell-tale signs of a clogged soakaway are a raised water level in the second compartment. Is the water level higher than the exit level of the outlet pipe? If yes, you have a more serious problem because fats and soaps have probably passed right through your system and coagulated in the walls of the soak-pit, forming a waxy cocoon that prevents effluent runoff from percolating away into the soil. Sorry, but you need to call a plumber for this. [NB! Do you live in an area with a high water table? Is it winter? If yes, smile and remember that the grass is always greener over the septic tank- the water will subside with the rains.]

Remember – Prevention beats cure!

To prevent problems from occurring in the first place, we suggest that you dose 100g of Sannitree Bio-Enzymes into your tank each month. If you have a high volume of people passing through your property (perhaps you own a B & B) –then we suggest that you also add 100g of Free Flo Granules. This will attack any fats and soaps that pass into your soakaway.
