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. Watch the video for more information.

Norma Hiles 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.

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.

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.

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.

Reasons to use bacteria in your septic tank...

Plumber smelly septic Tank Treatment - hand holding wrench

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.

don't pump out smelly septic tank truck

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.

The bacteria digests the waste into smaller particles that then flow freely and unobstructed through the drain field and seepage slits.  

Just one sachet per month of Flush-It is sufficient for a six-person household and will prevent disasters for both you and the environment.

Frequently Asked Questions

people questioning about Music School

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.

person questioning about Music School

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.

person questioning about Music School

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.

people questioning about Music School

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.

person questioning about Music School

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.

Computer Questions about Music School

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.

to make my septic work?

person questioning about Music School

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.

Computer Questions about Music School

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.

people questioning about Music School

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.

person questioning about Music School

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.

Computer Questions about Music School

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.

Read Some Septic Tank Horror Stories and How the Problem was Solved by Biomaster

The septic tank that was brought back to life from the dead...

Here is my horror story…
Our septic tank outflow into the gravel beds was becoming really smelly so we contacted a septic tank pumping company (as the tank had never been pumped in its 20 year life). They arrived with their metal detector and found a possible tank beneath our pavers. So we dug up quite a large area of pavers and the soil underneath only to see that we had only found a transfer box where the overflow from the septic tank went before it transferred to the gravel beds.

Looking at the direction of the transfer box input, it became clear that the actual septic tank was underneath our tankstand which is a large concrete slab supporting a 22,500 litre rainwater tank. To pump the septic tank would require emptying and removing the rainwater tank and then breaking up the concrete slab in order to access the septic tank.

We decided to leave it for the time being and so filled in the hole above the transfer box and restored the pavers, leaving the smelly outflow still there. Then I searched the internet and found Biomaster treatment packs which I immediately purchased. We followed the treatment guide for a problem system and in a couple of weeks the smell disappeared. Now we find we only need to repeat the maintenance treatment every couple of months to maintain a smell-free system. Many thanks Biomaster!

The deadly smell that almost destroyed a couple. Inside and outside, nowhere was safe...

Moving from the city to the country in March 2017 meant that many physical, emotional and practical adjustments had to be made.The biggest adjustment in  the early stages was to having a septic tank and no town water!  That was a HUGE change, and to top it off, we had to pay a plumber for a contract to service the unit several times a year.  

But the SMELL!  How were we going to survive that??  If the wind blew the wrong way, (and any way seemed to be the wrong way), the house reeked of sewage, and nowhere, inside or outside, was pleasant to sit and relax. The plumbers didn't seem to have an answer, turning  the agitator up, turning the agitator down, shutting the windows (!), changing the taps to allow water to run to the garden, all to no avail. We were very careful to buy "septic safe" detergent products for both the laundry and kitchen, making sure we did our bit in an effort to solve the problem.

The plumbing contract allowed us to have four visits per year, we certainly exceeded THAT number in our first year! THEN, we discovered Biomaster, and Flush-it.  What a great discovery!  The smell was greatly reduced, we could open the windows near the bathroom and get (almost) fresh air.  We became conscientious users of Biomaster's products, despite the contract plumber's words "Oh no, don't use that". Did they even know what it was?
Time went on and we still got unpleasant "whiffs" from the septic tank but there came a time when we had to call a different plumber for another reason.  

After a conversation about the septic tank the second plumber investigated and found that the silicone seal around the base of the toilet unit was cracked, thus releasing odours directly into the house. The crack was sealed with silicone, no more nasty smells in the house or around the house outside. What a relief! It was possible to invite visitors to our new abode, without the anxiety of being unable to provide gas masks for them.

We have changed the plumbing arrangements and continue to use Biomaster products with great faith that the septic system is now being managed as well as possible. In the short term Flush-it solved our problem and we believe that it will be a great product into the future.

When the cost of a new system scares you half to death...

I first saw a post about Biomaster products on Facebook about 4 months ago, at the time we were starting to think our Septic had reached its use by date and we were going to have to get the whole system replaced, we were having to pump out our tank twice a week at this stage. I decided we had nothing to lose by giving Flush-It a try.  

We started using it once a week for a month and noticed a huge improvement after about 3 weeks (back to pumping it out once a week).  We now use Flush-It once a month and have not had to pump out our tank at all for about 5 weeks. I intend to keep using Flush-it once a month from now on, thank you so much for this amazing product, I’m so glad I decided to give it a try.

The dark muck that came up from the drain to ruin lives...

It started out simply enough. First there was a bit of a smell in the air (not all the time, just every now and then). I didn’t think too much of it, until the shower drain started running slow and the bathroom sink had a bit of a smell about it. I was able to get the shower drain to unclog by using my foot as a plunger and “paddling” over the drain until it subsided. The worst of it being that I was paddling in greywater...hmmm maybe it was a bit darker than that...    

The toilet was the next thing to play up (naturally) I’m told things happen in 3's. I wasn’t about to stick my foot in the toilet to use as a plunger, so I grabbed the mop and plunged it up and down until it cleared. Oh well I needed a new mop anyway. Thanks to some strategic advertising by the good people at BioMaster, I found the answer to my Septic horror story when I Googled “How to fix Septic Tank problems "naturally" Australia?” and an article about “Flush-it” came up. I ordered a starter pack and within a few days I was able to kick-start the Septic and get it healthy again, thanks to this Australian made product.

"Thank you for forwarding our next 12 month supply of Flush-It. Previously with the fluctuation in the number of people staying on-site using our septic system occasional odours used to escape from the septic tank. Since introducing Flush-It early last year our system has shown a dramatic improvement."

I used one Flush-It sachet per week for 3 weeks and the smell is gone. Not only that but the lawn where the trenches are look so much healthier.

12 month Flush It bacteria Product for Smelly Septic Tanks

“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. Cheers” Tony, NSW.
