Black specks in Thetford flush water

[mikemelson]

Hi,

I have a Thetford C2 with the separate flush tank, I use Thetford pink additive in this tank. I have been getting black specks in the water when flushing the loo, but it's getting worse, in fact, if not used for a few days the water comes out totally black at first.

Anyone out there know what causes this problem and what's the cure?

There is a black rubber hose that connects to the glass tube which acts as the level gauge, could this be breaking up?

Suggestions will greatly appreciated.

Thanks, Mike.

It's a common problem, and has been discussed on here recently.

This is what we did:

 

 

 

Drain tank.

 

Throw away all bottles of rubbish and uber-expensive Theford "pink" stuff.

 

Refill tank with fresh water

 

Add some cheapo automatic washing machine liquid instead...choose your preferred fragrance at Lidl/Aldi.

 

 

 

 

 

 

Save loads of dosh, works a treat, and no more black bits :-D

Just to add a footnote to BGD's post don't go too mad with the bio washing liquid, a little goes a long way, too much will create bubles and will be difficult to pump through (bubbles don't rinse very well)
