Because of the popularity of our non-pDCB urinal
blocks, other companies have emulated the concept.
However not all are
what they seem.
This picture show the results of comparative solubility tests on non-pDCB urinal blocks.
The flask on the left shows Bio-Productions block, which has completely dissolved so that only coloured water appears to be in the flask.
The flask on the right shows a competitor’s non-pDCB block which contains an insoluble
clay filler. This does not dissolve and is known to cause blockages in
outlet pipes and urinal traps.
Not all urinal blocks are created equal !!
