GW6-15 Tanami Waterless Urinal Bowl

 

The GW6-15 Tanami waterless urinal bowl uses the same valve and "snorkel" technology as the popular GW6 cartridge.The urinal is manufactured in ceramic and is suitable for exposed pipework. The Tanami now incorporates the latest version of the GW6-15 valve core with much faster drainage - approximately 12 litres per minute. This allows for more effective sluicing of the waste pipes to keep them even cleaner. Chemical resistance has also been much improved, particularly against bleach, to which silicone valves are particularly vulnerable. The dual valves are now manufactured in a special silicone to reduce the chance of damage from harsh cleaning chemicals, although these are still best avoided in order to maximise the life of the cartridge.

Note: The bowl shown in the YouTube video demonstrating the GW6-15 is not the Tanami urinal.

• Saves water, thus reducing energy and emissions 
• Reduced expenditure on water and related sewerage costs
• No floods
• Unique dual valve technology for added protection against odours
• Small, replaceable GW6-15 valve core typically lasts for 4-6 months
• No sealant required
• High drainage rate
• Manufactured in ceramic
• No trap required connects directly to waste

Instead of a fluid barrier, the GW6-15 valve uses a silicone double-skirt valve which is tolerant of both water and common cleaning chemicals.

How to avoid blockages in waste pipes

Whilst the waste pipes of waterless urinals block less frequently than for most flushed urinals, uric acid salts can still form a sludge which eventually could cause a blockage. Sludge can be a particular problem if the waste pipes are shared with sinks or are poorly configured.  Gentworks recommends periodic sluicing with Bactericidal Cleaner to break down this sludge and carry it away into the main drain. The GW6 valve can be sluiced regularly; once every 2 to 4 weeks is recommended.  The solution used should be approximately 1 part Bactericidal Cleaner to 9 parts warm water from the washroom hot tap.
