Toilet Liquids & Septic Tank - Confused.

[Pebble]

We're soon to be staying on a site for a couple of weeks where you have to empty your cassette into a septic tank.

 

We currently use blue in the cassette and pink in the flush tank. I'm aware that Thetford Green (suitable for septic tanks?) can replace the Blue but as a more cost effective and availability long term solution, should I use bio or non-bio washing liquid?

 

I know that a lot of you use bio liquid in cassette but, if I've got my facts right, bio liquid isn't good for septic tanks. So, should we be using bio or non-bio in the cassette and what about the pink in the flush?

Bio clothes washing products are excellent for septic tanks.

They are enzyme based and start the break down, just what the bacteria in the septic tank want.

They have been sold for years for their intended purpose to the countless thousands of people like us who have [had] septic sewage systems.

Tescos own, £1. 5ish for 28 treatments.

 

ps; never bother with the pink, but recall that was first rate at supporting algae growths, as black debris in the flush water, so no hint of worry there.

 

I do always empty my cassette every morning as the tank is too heavy otherwise for me. Note the bio has no colouriser or much disguising scent, but it sure slurrifies things.

So Bio it is then. How much liquid per cassette, perhaps a capful (using the cap that comes with the bio bottle)?

 

Could you also use bio in the flush tank just to give a little odour to the flush?

Have just found this which says non bio for septic tanks http://www. ecoverdirect. com/products/concentrated-laundry-liquid-non-biological/econbluenonbio. aspx?productid=econbluenonbio

 

Other threads and posts on the net also suggest non bio for septic tanks but how will non bio deal with the wee and poo in our cassette?

Why not just use the correct green chemicals designed to mask the smell and break down stuff? You won't have to worry then

 

If away long term I can see why some may choose to save a few pennies but not if on a septic tank site for a couple fo weeks only. Plus lets face it its an unpleasant enough job as it is, why use something that won;t hide smell or sight of your last nights spag bol going down the chute. ...

We use Lidl Formil BIO Liquid And use the cap on container as measure . . We empty everyday

There is nothing wrong with putting non bio in septic tanks either, don't think it gives the tank the same initial help but does no harm and certainly does not suggest bio is unsuitable.

For your cassette you need that non bacterial breaking down the enzymes give, or you are in danger of bacteria action in the cassette; what the biocides of the normal fluids hold at bay.

I use a cap full per charge, at the price never explored if I could save by using less.

The own brands have no real amount of scent so I don't see an obvious reason to put it in the flush tank, can't on mine as they flush from the water system.

Why not just buy the correct Thetford Green and be done with it, its not that expensive
