Biological Conventional chemical
- Odours
- Digests the organic waste that causes the smell
- Perfume or para blocks mask it until they wear off
- Pipes & traps
- Keeps uric scale and grease from building up in pipework
- Only reaches the bowl or trap; build-up continues out of sight
- Water
- Clean urinals can be flushed just 4–6 times a day
- Frequent flushing to keep smells down
- Safety
- No pDCB or other dangerous, carcinogenic chemicals
- Para blocks carry a carcinogen warning; caustic and acid products need careful handling
- Drains, grease traps & septic
- Adds the good bacteria that break waste down
