Septic systems are prone to getting smelly and blocked up

If you have a nasty septic smell – it is not only embarrassing, but it is unhealthy. Pumping the tank out will not necessarily fix the smell. Your septic smells because there is not sufficient bacteria in the tank to degrade the waste properly.

Just one sachet of Flush-It® dropped into the toilet pan last thing at night once a month is the answer to your septic and drain field problem.

    My septic tank has had an odour for months. Embarrassing when people come around. I had it pumped out and still had the odour. I went on to Google and thought I'd ring Biomaster. I purchased the pack and had it sent in overnight mail. I put the tiny sachet in the toilet as per the instructions and I have had no odour since. It works.

  • Ann Cathrine Rousseau

    Excellent stuff works very well. Highly recommended have used it now for the last eight years no problems with the septic tank at all.

  • Marion Taylor

    I have used this product. Its excellent. I inherited a very smelly tank (with a soakage pit). I had it pumped out, added blood and bone as I was advised (there were no dead cats at hand!). Nothing helped until I tried the Biomaster Flush it product. It worked like a dream. I use it monthly and now also use their drain and grease products regularly. Highly recommended.

  • Julia Ritson

    My septic had a serious problem when my husband was having chemo for myeloma. I tried other products that the hardware and supermarkets sell and they didn’t work. I came across  your products and tried the “flush it” starter pack and was amazed how well and how quick it worked. I did need to use it regularly and sometimes after his treatment I used extra sachets.

  • Gordon Anderson

    We had a plumber tell us our drainfield was too small when it was a normal size but we gave our system 2 goes of the shock treatment and it's fixed.

  • Rhonda Stubs

    I have had Septic Tanks for over 30 years on two different properties and have never had to have them pumped out. A properly maintained septic should not require pumping. Good Bacteria is key.

  • Georgia Green

    I used this.... this week actually....just as a prophylactic....but I was really surprised that the toilet started flushing really well again and there used to be a funny black stain come into the bowl...well....all clear now.... product arrived in good time too.... thank you

  • Errol Sponneck

    I didn't have a problem but i decided to try the product a month ago anyway. I'm very pleased with the results so far. Whenever the showers upstairs were being used I had a gurgling in my laundry downstairs. It disappeared after just one day so there must have been a blockage. Now one month later I have put in the second dose. I have now also bought the compost improver and the stuff for the grease trap too.

Reasons to use bacteria in your septic tank...

  • Avoid plumbers call out fees for blockages

    Using 1 teabag sized sachet of good bacteria is a DIY solution that is:

    • Faster
    • Cheaper
    • Easier than calling a plumber

    Environmentally safe and non-toxic.

    The good bacteria actually digest common pollutants.

    When pipes are slow, clogged or the toilet is blocked the whole family suffers.

    Flush-It contains over 60 different strains of beneficial bacteria specifically designed to eat through waste and toilet paper.

    Flush-It

    • Cleans pipework
    • Clears blockages
    • Prevent nasty problems

    Stops nasty smells returning.

  • STOP... Don't pump out, use good bacteria instead

    A septic tank doesn't have to be full to smell. After pumping out, the smell can come back within a few days. This is due to the lack of good bacteria in the tank.

    Odours from pumping your septic tank are:

    • Unpleasant
    • Unhealthy
    • Embarrassing

    Regular pump-outs are

    • Costly
    • Unnecessary
    • Doesn't fix the underlying problem

    Just one sachet of Flush-It dropped into the toilet pan once a month, last
    thing at night, is enough to restore the good bacteria levels your tank
    needs for peak efficiency and this will prevent future issues.

    So, there is no need for pump-outs!

  • Avoid a costly blocked drain field

    A new drain field can be incredibly costly to replace ($8,920 - $19,640 depending on size and location).

    A blocked drain field can lead to the formation of:

    • Smelly, greasy pools on the surface
    • Slow under-trench drainage

    Research shows that a badly working drain field will pollute creeks, rivers and underground streams up to 52 kilometres away.

    Flush-It septic and drain field treatment is the fast, easy, effective and efficient way to ensure drain field health.

    Thebacteria digests the waste into smaller particles that then flow freelyand unobstructed through the drain field and seepage slits.  

    Justone sachet per month of Flush-It is sufficient for a six-personhousehold and will prevent disasters for both you and the environment.

Frequently Asked Questions

What is the difference between Bacteria and Enzymes?

Bacteria form their own enzymes to deal with the waste they encounter. Enzymes can be deactivated by harsh cleaning products – the bacteria form more enzymes to take their place.

How long does it take for the smell to go once I have treated it?

For septic tank treatment – it takes 1 – 3 days for the smell to completely go.  It starts to lessen in one day.  For sinks and drains – the smell Is usually gone in 24 hours.

Does Flush-It work for long drop toilets at a campsite?

Flush-It is ideal for long drop toilets – currently used by NSW Parks and Wildlife for this purpose.

The difference between the Starter Pack and the normal pack of Flush-It?

The Starter Pack is for use for either new systems or when your system is in trouble – i.e. producing smell or soggy drain fields or overflowing. These two sachets have a higher count of Beneficial Bacteria in and you use the two sachets in the first week – a shock dose. If you have two toilets, use one sachet in the toilet furthest from the septic tank and 2 days later use the other one in the second toilet. After that you should be able to go to one sachet per month for the whole system.The Flush-It two pack, 3 pack or 12 pack are suitable to maintain a system that is working, but by using Flush-It – one sachet per month, will cut down on pump outs and keep both the drain field and septic tank healthy and working efficiently and smell free.

Why does my bathroom still smell when I have just cleaned it?

Because the pipe that runs from the grating to the UBend collects toothpaste, body wash, shampoo etc. then hair and other material sticks to it – this becomes smelly and makes your bathroom “woofy” even when it is clean.  (Don’t forget the floor drain as well).  Use Drainpower – just a cupful down each outlet last thing at night will solve the problem.

Can I use Yogurt to make my septic work?

Some people say that Yoghurt/Milk fixes their septic system and is good for it.  Yoghurt/milk will not do any harm to your septic, but will not get rid of the septic smell caused by lack of good beneficial bacteria and it will not break down the solids in your septic thereby causing the drain field to become slow and eventually blockages may occur.  In the "good old days" people used dead roadkill, blood and bone, yeast, molasses or other tried and tested cures for their stinky septics, but because today we have much harsher and more diverse cleaners, cleansers, shampoos and medications, a wide spectrum of good bacteria such as in Flush-It (which has 60 different strains of beneficial bacteria)  is required and reduces the need for expensive pump outs.

Can I use ROADKILL to make my septic work?

In the "good old days" people used dead roadkill, blood and bone, yeast, molasses or other tried and tested cures for their stinky septics, but because today we have much harsher and more diverse cleaners, cleansers, shampoos and medications, a wide spectrum of good bacteria such as in Flush-It (which has 60 different strains of beneficial bacteria) is required and reduces the need for expensive pump outs.

Can I use Blood and bone to make my septic work?

Thanks for your comment. Unfortunately, blood and bone won't get rid of the smell and it doesn't have the bacteria needed to actually break down the waste. Flush-It has up to 60 different strains that are designed to deal with the complex things that go down your sinks, toilets and drains.

Can I use Sugar to make my septic work?

Sugar/Molasses excites bacteria for a short amount of time but doesn't continue to work in the drain field. There are a lot of home remedies out there that help for a short time but they just aren't as efficient as Flush-It. We have designed our bacteria to deal with problems like smells and blockages because we had a septic tank problem over 15 years ago so we worked with scientists to create something amazing that not only worked for us but for others with the same problem.

Suggestions for keeping your system safe?

Chemicals like solvents, oils, paints, disinfectants, pesticides, household cleaning products and bleaches can kill the bacteria in your septic system. This may kill the system and stop it digesting effluent.‍

Solution: switch to septic safe products and use smaller amounts than you usually would.

Also changing washing powders can make a difference. Septic systems don't like too much phosphorus so look for low-phosphorous or phosphorus-free detergents and that will help.

Why do I have a smell from my Sullage / Grey Water tank

The smell is caused by the formation of algae in the tank.

You can use Flush-It to get rid of the smell. We have a lot of customers that use Flush-It specifically to solve this problem.‍

It is best to put the Flush-It into an old stocking with some stones to weight it down and hang it into the tank.  That way you can always replenish the Flush-It later.

Can I use Garden Lime to stop my septic smelling?

Garden lime will temporarily get rid of the smell but will not address the problem of there being a lack of bacteria to break the waste down.

A wide spectrum of good bacteria such as in Flush-It (which has 60 different strains of beneficial bacteria) is required to work efficiently in the tank but also will stop blockages in the drain-field.

Don’t let these items ruin your septic system

Chemicals like solvents, oils, paints, disinfectant, pesticides, household cleaning products and bleaches can kill the bacteria in your septic system. This may kill the system and stop it digesting effluents.

  • Robyn & Ian – Premier award winning luxury retreat – Northern NSW

    "Thank you for forwarding our next 12 month supply of Flush-It.

I would recommend Flush-It to anyone with similar problems. It's great!"

  • Tony – Sydney – New South Wales

    “As a specialist in the wastewater treatment industry I can testify that Flush-It is an excellent product that provides a diverse variety of microbial cultures suitable for biodegrading a great variety of difficult-to-consume contaminants found in a variety of waste-water and sewerage systems. As a rule, I use Flush-It as a starter culture for my grey-water, sewage and industrial wastewater treatment systems to get optimum performance. Unlike an imported product that is widely available, the microbes in Flush-It are suited to Australian conditions, particularly the colder temperatures experienced South of Brisbane, as the competing product that I and colleagues have tried with no luck is suited to the extremely hot conditions in the Middle East where it is manufactured.
